Failings of a categorical systemFor decades, standardized classification systems have attempted to define psychiatric disorders in our mental health care system, with the Diagnostic and Statistical Manual of Mental Disorders (5th ed.; DSM-5; American Psychiatric Association (APA), 2013) and International Statistical Classification of Diseases and Related Health Problems 10th revision (ICD-10; World Health Organization, 2010) being internationally best-known. One of the major advantages of the DSM must be that it has seriously diminished the international linguistic confusion regarding psychiatric disorders. Since (...) its introduction, it contributed extensively towards one common international language for defining and conceptualizing psychiatric disorders. Strikingly, within the field of psychological testing a similar step forward seems to have not yet been taken. At present, there exists no international standard for the use of psychological tests that takes the definition of a specific symptom as listed in DSM-5 as its starting point, and reliably and validly measures this symptom. Rather, the majority of tests are measuring constructs consisting of a multitude of symptoms. For example, the Beck’s Depression Inventory (Beck et al., 1996) measures core symptoms of depression summing up to a depression score. Accordingly, we believe it is time for a change. The diagnostics of psychiatric disorders, where disorders are defined as nosological units with a single cause, a single organic substrate, and a single time course, has been problematic for centuries. The field of psychiatry has always been ambivalent about its desire to follow a medical model (Blaney, 2015), but afflicted due to its definitions of pathology. The definition of a psychiatric disorder in DSM-5 offers little room for a clear cut pathogenesis and harsh demarcation of syndromes. This is reflected in the DSM-5, where it states: “A mental disorder is a syndrome characterized by clinically significant disturbance in an individual’s cognition, emotion regulation, or behavior that reflects a dysfunction in the psychological, biological, or developmental processes underlying mental functioning” (APA, 2013, p.20). An unfortunate and recognized consequence of this definition within the current system is that many symptoms overlap within categories of psychiatric disorders and patients end up diagnosed with many co-morbid disorders.Two fundamental problemsRegardless of new attempts to improve the diagnostics of psychiatric disorders, the DSM-5 represents the status quo. Consequently, the distinction between diagnosis and classification remains substantial and more than a discussion on semantics. We identify two fundamental problems within the current framework. Generally, a psychiatric diagnosis is considered to be descriptive (Hengeveld and Schudel, 2003). The clinician will describe a syndrome (its nature, timespan, and severity) within the framework of a disorder, and often include a differential diagnosis, predisposing protective or vulnerability factors, and provoking or maintaining factors. Within the DSM-5 framework, a similar ‘approach to clinical case formulation’ is taken (APA, 2013, p. 19). Evidently, a descriptive diagnosis has a hypothetical character. It consists of the clinician’s hypothesis and is based on his or hers professional considerations according to the abovementioned factors. Once the clinician has formulated a descriptive diagnosis, it is then complementary ‘translated’ into a DSM-5 classification. Herein lies the problem. For the layman, the existence of this distinction between diagnosis and classification is usually unknown. Preceding treatment, the clinician will give the client a classification of the existing psychiatric problems and the client may attribute more meaning to it than appropriate, thereby fostering the risk of reification. Second, the DSM-5 is a categorical system. Thus, individual disorders are regarded as discrete units – ‘you either have it, or you don’t’. DSM-5 states about this: “(…) scientific evidence places many, if not most, disorders on a spectrum with closely related disorders that have shared symptoms, shared genetic and environmental risk factors (…)”. And “(…) we have come to recognize that the boundaries between disorders are more porous than originally perceived.” (APA, 2013, p. 6). This leads to a fundamental problem. Because the overwhelming majority of psychiatric disorders examined thus far using taxometric methods appear to be dimensional in nature (Haslam, 2003; Widiger and Samuel, 2005), consequently all of their categorizations become artificial and debatable. Even though DSM-5 took a modest step towards a more dimensional approach, its core remains categorical. To illustrate, consider the Borderline Personality Disorder (BPD). This classification consists of nine diagnostic criteria of which a minimum of five need to be present for the diagnosis of BPD. A simple numerical combination algorithm leads to a staggering number of 256 distinct presentations of BPD (Albion et al., 2013). Due to this chameleon-like nature, the disorder’s diagnostic validity becomes questionable. Strikingly, this number is relatively small when compared to other conditions, e.g., there are 636,120 ways to have posttraumatic stress disorder (Galatzer-Levy and Bryant, 2013).DSM-5 does propose an alternative model for personality disorders based on personality functioning and traits (APA, 2013, p. 761), as a possible answer to the problem that most patients fit with multiple co-morbid personality disorders or to the category of personality disorder not otherwise specified. In November 2012, the chair committee of APA decided to move this alternative model to section III of DSM-5 and to sustain the categorical system in section II. A potential solutionDSM-5 and its predecessors have brought about an invaluable improvement regarding the formulation of a common international language for psychiatric disorders. However, the individual disorders fit poorly with its starting point of discrete units and strict boundaries. Van Os (2014) has argued for a better balance between the categorical and personalized aspects of psychiatric disorders. We argue for a two-step approach.Particularly due to the ‘weak boundaries’ between disorders, it might be beneficial to limit ourselves by merely categorizing clients into the main categories of the DSM-5 according to their most prominent symptoms (Van Os, 2014), i.e. their main complaint. In other words, clinicians could first ask themselves whether the symptomatology is concerning a neurodevelopmental disorder, or a bipolar and related disorder, or a depressive disorder, and so on. It will drastically reduce the over 400 classifications in DSM-5 down to 20 categories. Van Os (2014) even argues to combine some of the main categories, reducing this number even further to 15 categories. The advantages of reducing the over 400 classifications are fivefold: 1) a syndrome, being an aggregation of symptoms, creates a false relation between symptoms that are that are already heterogeneous themselves; 2) 15 broad categories are functional: it results into a very heterogeneous group of clients within a category and thus prevents stereotypes and invites further personalizing of complaints; and 3) a dimensional measure of a symptom rather than a syndrome will correspond better with the client regardless of it not providing the complete picture. Focusing on the main complaint will indicate where there is an immediate need for care (Van Os, 2014); 4) it will allow clinicians to recognise subthreshold conditions more easily (Magruder and Calderone, 2000); and 5) it might facilitate the development of clear demarcations between normal and abnormal functioning (Kessler, 2002; Widiger and Samuel, 2005). Please, see also Table 1.This also fits well within scientific advances, as thus far strongest evidence has been found for a distinction between internalizing and externalizing disorders, even superseding these 15 main categories (DSM-5; APA, 2013, p.13, but see Weiss et al., 1998). The second step would concern the personalized aspect, which we argue to define on a level of core symptoms of the specific main category, to be agreed upon later. To assess these core symptoms, the field of psychological testing could develop an internationally applicable instrument to reliably and validly measure each (core) symptom on a dimensional scale. Many of these instruments are readily available and have proven its psychometric properties within scientific research. Elements from these instruments could be easily transformed to work within the new system. Within the field of psychology, this approach could aid development of a common international language to define symptoms, analogous to the field of psychiatry. Importantly, current psychological testing mainly implies the use of self-report measures. This leads to an abundance of auto-amnestic information. To increase the reliability and validity of psychological tests to assess DSM-5 symptoms, it may be important to add two additional information resources. This would entail psychological tests where a next of kin answers questions about the symptom of the client, and psychological tests that include the clinicians’ judgment, such as structured clinician-based interviews. Conversely, we also need to acknowledge the well-known limitations of clinical judgment (e.g., Faust, 1986; Garb, 1998). Advantages of a new frameworkThe changes we suggest have big implications and are not easily implemented in the current framework. Clients may prefer the comfort of a single clear label, similar to what they are used to in other areas of medicine. Health insurance providers and policy makers may argue for single labels as well. Therefore, it would require a lot of explanation from our clinicians to promote a change. Our suggestions for broader categories may not disambiguate the current situation better than the existing approach, but it will promote personalisation of health care. Difficulties in diagnostic reliability will remain in disorders that fall on the boundaries of the taxons, e.g., schizoaffective disorder versus bipolar disorder with psychotic characteristics, which may benefit from further study. There are also some politically tinged questions to keep in mind: How will we finance our health care, and how will we ensure a gradual transition from the current financing system, including clients who already have their labels? What about visitations from insurers and health inspection? How can they control for a good standard of quality in health care when considering the increasing heterogeneity? Nevertheless, we argue that the benefits outweigh the disadvantages. We will see a shift from a categorical to a personalized approach, which will lead to less (self) stigmatizing, less estrangement, and it will challenge reification thinking. DSM-V states that “a reformulation of research goals should also keep DSM-5 central to the development of dimensional approaches to diagnosis that will likely supplement or supersede current categorical approaches to diagnosis in coming years” (APA, 2013, p. 13). Our proposition for psychological testing on symptom level could contribute to this development. Furthermore, this new approach will do more justice to the heterogeneity of symptoms within and outside of classification categories, see also Table 1. Moreover, in this new approach we join forces of expert knowledge from the fields of psychiatry and psychological science. Finally, it offers new and potentially better opportunities to map health care needs. This in turn will lead to a better interface for allocation of appropriate treatment. It will present a clearer picture of when preventative care is preferred over treatment and vice versa. Importantly, health care needs will be more closely attuned to the ‘own story’ of the client.We argue for the national and international psychological associations in Europe and the United States of America to support the idea of a collective approach to develop an internationally standardized psychological testing battery to reliably assess all the core symptoms of the main categories in DSM-5.

Bizarre delusions are not specific to schizophrenia and can be found in other psychotic disorders. However, to date, there are no studies investigating socio-demographic and clinical characteristics associated with BizD across the psychosis spectrum. In this study 819 subjects with a diagnosis of SZ, schizoaffective disorder and bipolar I disorder were included. Patients with history of BizD and with no BizD were compared with respect to socidemographic and clinical variables, and predictors of BizD were explored. Patients with (...) BizD were less educated, less likely to be married, had higher Positive and Negative Syndrome Scale negative scores and lower Young Mania Rating Scale scores. Younger age, SZ and SZA diagnoses, higher PANSS positive scores, presence of reference delusions, tactile and olfactory hallucinations were predictors. Our results indicate that BizD are associated with higher illness severity, lower functionality and specific set of symptoms. (shrink)

This manuscript describes the responses and correlates of outpatients with schizophrenia spectrum disorders to a tool designed to measure comprehension before obtaining informed consent for research participation. We used the Evaluation to Sign Consent form to document comprehension in 100 outpatients as part of their consent to participate in an ongoing study of an exercise intervention. The findings suggest that using this form is a feasible and acceptable approach to documenting comprehension of research procedures prior to obtaining informed consent. Age (...) 49 years and older and the receipt of intramuscular antipsychotic medication predicted the need for additional assistance to complete the Evaluation to Sign Consent form successfully (χ2 = 8.29, P = 0.016). Nurse researchers should consider documenting comprehension with this tool owing to its availability, time efficiency and utility. (shrink)

Despite substantial research on overall decision-making capacity levels in schizophrenia, the factors that cause individuals to make errors when making decisions regarding research participation or treatment are relatively unknown. We examined the responses of 84 individuals, middle-aged or older, with schizophrenia or schizoaffective disorder. We used a structured decision-making capacity measure, the MacArthur Competence Assessment Tool for Clinical Research, to determine the frequency and apparent cause of participants’ errors. We found that most errors were due to difficulty recalling (...) the disclosed information, particularly the study’s procedures, potential risks, and purpose. Errors attributable to concrete thinking, psychotic symptoms, or perceived coercion were rarer. These results suggest that informed consent procedures for this population might be improved by providing information in a way that facilitates learning and memory, such as iterative disclosure of the information, corrective feedback, and emphasis of key points of the study—for instance, its purpose, procedures, and potential risks.

In lieu of an abstract, here is a brief excerpt of the content:Lack of Autonomy: A View From the InsideSteve Weiner (bio)Keywordsagency, autonomy, deficit, determinismThe most vivid and truly overwhelming response I have to all arguments stressing agency/autonomy, that is, what lay people call free will, is this: that I’ve never had the sensation of acting autonomously since the onset of my mental illness on August 28, 1965. I have never been comfortable with saying that “I made a choice,” or (...) with other people either lecturing me or attempting to reassure me, often at the same time, by saying that I acted with autonomy/primary agency, as it were. That is my overwhelming subjective experience. I usually refrain from attempting to make a general case for determinism about myself or the universe in general, although, again, I feel far more determined than free. (I would note that Mary Midgley [2006] points out that the word determined and the concept, by extension, of determinism have two different meanings in say, social theory and geometry.)One strong criticism of this article I would put forward is that the Davidson and Shahan seemed to mention only depression among many diagnoses to make their case, although their French mentors/ co-thinkers apparently focused on schizophrenia, however unusually defined by them. In obsessive-compulsive disorder, we all have the very strong impression of the obsessive thoughts having been forced into our mind by something or someone else. My impression is that we all engage in our warding-off rituals, especially in the later, most frequent, most ritualistic repetitions, “against our will.”My most frequent diagnoses over the decades have been paranoid schizophrenia and schizoaffective disorder, and I more or less agree most of the time with those labels. I find Louis Sass’ “discovery” that our delusions are better thought of as semi-delusions with our simultaneously believing and not believing them, and our usual failure to take action on them, pretty well describes my own long-term experience. I know he is insistent on ascribing some degree of agency/whole personality involvement to us as compared with the standard National Alliance on Mental Illness/biological model, but I feel that he is getting closer to most of the “truth” when he talks about a subtle interweaving of affliction/deficit and agency.The authors’ reliance on French thinkers almost inevitably sends me back to a once-prominent French intellectual, one of my favorite writers Albert Memmi, the Tunisian-Jewish born socialist and Zionist. In a book that mentions The Story of O, (Memmi 1984) a story of extreme sexual submission or masochism, he makes the striking remark that the mentally ill are “oppressed from within.” I have spoken of this often because it seems to touch perfectly on my experience and that of fellow mentally ill people I have met. From the perspective of the outsider, it seems that the whole [End Page 237] and integrated person is involved in every behavior. What looks like agency to others, especially when it comes to undesirable behaviors, when experienced from within, is actually a situation of affliction from a seemingly autonomous place. We experience this as coming, yes, from within us, but not ultimately of us.I cannot be sure, but a belief in some degree of metaphysical choice from the beginning of one’s life seems to me the only way the authors of this article can firmly, enthusiastically come down on the side of agency as opposed to deficit/malfunction in trying to explain human problems. In contrast, I suppose I could be called a physicalist. I have noticed that physical substances (alcohol, caffeine, psychiatric drugs) have such a vivid and consistent effect on my mind that it makes sense to me to conclude that yes, mind is probably ultimately reducible to brain/body/experience of the senses. That is my private opinion based on experience as mediated through knowledge/intellect.One final point: Despite the (almost certainly) radical left politics of the authors, as an officially disabled person almost completely dependent on the welfare state, I fear that in competitive individualist America, the authors’ hoped-for far greater emphasis on autonomy will feed into popular “blame the victim” ideology. I believe... (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Psychiatric Comorbidity:More Than a Kuhnian AnomalyPeter Zachar (bio)Keywordscomorbidity, classification, epidemiology, differential diagnosis, personality disorderDr. Aragona's article in this issue of Philosophy, Psychiatry, & Psychology makes some important points regarding the relationship between comorbidity rates and the classification system currently used in psychiatry. Particularly persuasive is his claim that observed patterns of comorbidity are, in important respects, consequences of the structure of the classification system. I am not convinced, however, (...) that comorbidity is best conceptualized as an artifact of the taxonic structure of the Diagnostic and Statistical Manual of Mental Disorders (DSM) and the International Classification of Diseases (ICD). Instead, I suggest that the use of dichotomies such as true versus artifactual should be used with caution when psychiatric classification is being discussed.In contrast with the artifact hypothesis, I argue that the phenomena covered by the term "comorbidity" are real, expectable features of the psychiatric domain. They are not the phlogiston and luminiferous ether of psychiatry. I am skeptical of the notion that high comorbidity rates as a whole can be understood as Kuhnian anomalies, or that there is a crisis, or that after a period of revolutionary science a new paradigm would eliminate these 'anomalies.' In short, high rates of comorbidity in psychiatry will not simply disappear once scientists develop a better nosological paradigm. High levels of comorbidity can, however, be both lowered and provided a better, evidence-based conceptual framework.Many Conditions, One OrganIn general medicine, comorbidity conventionally refers to the simultaneous occurrence of two independent disease processes or distinct clinical entities, such as heart disease and liver cancer (Feinstein, 1970; Jablensky 2004). The presence of one disease is supposed to affect the other in such a way that the co-occurrence of the two has implications for prognosis and treatment.Comorbidity in psychiatry is a broader concept, referring to a variety of conditions that overlap in multiple ways. The different kinds of overlap are amenable to detailed empirical analysis (e. g., Klein and Riso 1993; Neale and Kendler 1995). Depressive reactions to primary disorders, attention deficit symptoms associated with mania, panic attacks in the context of severe borderline personality disorder, substance abuse disorders among psychopaths, histrionic dynamics combined [End Page 13] with narcissistic personality traits, and emergent conditions such as schizoaffective disorder are all distinct types of comorbidity. The kinds of overlapping conditions just listed are sometimes termed psychiatric comorbidity. Also important is comorbidity between psychiatric disorders and general medical conditions as is studied in behavioral medicine and health psychology. The crisis, if there is one, is a crisis of comorbidities.The heart disease and liver cancer type of comorbidity as independent organ systems being affected is ruled out a priori in psychiatric comorbidity proper. In psychiatry, "psychopathological disease processes" can all be expected to affect a single organ, namely the brain or, more likely, affect the different systems that are tightly integrated in the brain. The tight integration can make putative comorbid psychiatric disorders difficult to disentangle.It is a widely held consensus that causes, not organ systems, are what matter in comorbidity. In this tradition, Dr. Aragona claims that in general medicine shared symptoms between two diseases (such as fever and fatigue) are not a problem because the diseases are differentiated with respect to etiology; in psychiatry, however, where syndromes are differentiated by a description of symptoms only, symptomatic overlap is a problem.Is descriptive psychopathology, therefore, a root cause of the "crisis of comorbidity" and should it be abandoned in favor of etiological classification? Unfortunately, forcing psychiatric nosology to conform to an etiological paradigm is unlikely to resolve the problem of psychiatric comorbidity. As noted, the problem is one of distinguishing between the different etiological disease processes that are affecting tightly integrated systems in the brain. The brain as a whole is a multilevel, dynamic, and open system, which has an ecology (Zachar 2000). As argued by Kendler (2005) and Schaffner (2002, 2008), it has not thus far, and may never be fully possible to segregate causes and their associated psychiatric disorders into parsimonious etiological packages. In the ecology of neuroscience, causes and effects tend to merge in a continuous series of common pathways.It would be foolish... (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Carmen MirandaJessica LesCarmen Miranda, she called herself today. She suffered from decades of schizoaffective disorder and now more recently, end–stage renal disease from uncontrolled diabetes. I first met Carmen two weeks prior when she had been brought to the hospital on a 72 hour psychiatric hold for self–harm. She failed to go to dialysis for a week, an act that would kill her if allowed to continue. (...) Now she was here again, for the same reason.Everyone of competent mind has the right to refuse medical treatment. Unfortunately, Carmen’s mind was not currently grounded in reality. So against her will, our family medicine team admitted her to the hospital and arranged for dialysis early the next morning. None of us liked doing this. Fortunately, when the time came for the dialysis tech to insert the dialysis catheter into her shunt, Carmen agreed peacefully. After her dialysis, we had no right to keep her in the hospital because her life was no longer in danger, at least until the next week. We discharged her to home. However the question remained, what about next time?To navigate this ethical gray zone, we called an ethics committee meeting. An ethicist, nurses, hospital social workers, the inpatient family medicine resident team, and most importantly, two people who knew her very well—her caseworker and long–term psychiatrist—discussed her case for an [End Page 103] hour. Our medicine team learned that in her last period of clarity two months prior, Carmen made contradictory statements regarding her wishes. Carmen told her caseworker she was tired of dialysis and being sick and stated it was time to let herself go. During the same lucid week she told her psychiatrist that she was grateful she had been forced to complete dialysis against her wishes after a run of non–adherence while suffering psychosis a couple of months prior. Now months later she was in a downward spiral, exacerbated by the deterioration of her mentally ill husband. If she missed a dialysis treatment here and there, it was okay, but when she went on a run missing several treatments, it was slow suicide.The ethics meeting concluded that Carmen needed to complete an advanced directive and select a power of attorney other than her gravely incompetent husband as soon as she was deemed competent. If she did not become lucid again, her psychiatric team should apply for conservatorship, a legally appointed person who serves as guardian for a gravely disabled mentally ill person. However, conservatorship would take months. In the interim, the ethics committee ruled that our medicine team would continue to provide lifesaving treatment for her, against her wishes if necessary.The ethics meeting adjourned but our medicine team remained in a gray area. To what length should we go to treat her? If she continued to refuse dialysis would we hold her in the hospital until she became sufficiently docile by inevitable uremia that we could peacefully dialyze her? Possibly. Would we go so far as to put her under anesthesia to complete her dialysis? Personally, I hoped not.Just three days after the ethics committee meeting, her caseworker found Carmen yelling nonsensical phrases through the front door of her home while her husband held the door shut with his beer belly and good shoulder. After gaining entry later in the day, Carmen’s caseworker found their mutual medication collection strewn in the bathtub and no food in the house. He placed Carmen on a psychiatric hold and transported her to the hospital. The emergency department paged me when Carmen arrived. I braced myself for the possibilities that lay ahead. When I reached Carmen, she was sitting in a room reserved for psychiatric patients and under watch by a friendly police officer accustomed to these situations.“Hi, Carmen,” I said, one step into her room. She sat on the edge of the gurney, wrapped in three blankets.“Cold,” she said.The police officer spoke from behind my shoulder, “She has been requesting cup after cup of ice water, she won’t take anything else.”“Let’s get you more comfortable.” I returned with a warm blanket and draped it over her...

People suffering from Obsessive-Compulsive Disorder (OCD) do things they do not want to do, and/or they think things they do not want to think. In about 10 percent of OCD patients, none of the available treatment options is effective. A small group of these patients is currently being treated with deep brain stimulation (DBS). Deep brain stimulation involves the implantation of electrodes in the brain. These electrodes give a continuous electrical pulse to the brain area in which they are (...) implanted. It turns out that patients may experience profound changes as a result of DBS treatment. It is not just the symptoms that change; patients rather seem to experience a different way of being in the world. These global effects are insufficiently captured by traditional psychiatric scales, which mainly consist of behavioural measures of the severity of the symptoms. In this article we aim to capture the changes in the patients’ phenomenology and make sense of the broad range of changes they report. For that we introduce an enactive, affordance-based model that fleshes out the dynamic interactions between person and world in four aspects. The first aspect is the patients’ experience of the world. We propose to specify the patients’ world in terms of a field of affordances, with the three dimensions of broadness of scope (‘width’ of the field), temporal horizon (‘depth’), and relevance of the perceived affordances (‘height’). The second aspect is the person-side of the interaction, that is, the patients’ self-experience, notably their moods and feelings. Thirdly, we point to the different characteristics of the way in which patients relate to the world. And lastly, the existential stance refers to the stance that patients take towards the changes they experience: the second-order evaluative relation to their interactions and themselves. With our model we intend to specify the notion of being in the world in order to do justice to the phenomenological effects of DBS treatment. (shrink)

In this paper, I present a challenge for Michael McKenna’s conversational theory of moral responsibility. On his view, to be a responsible agent is to be able to engage in a type of moral conversation. I argue that individuals with autism spectrum disorder present a considerable problem for the conversational theory because empirical evidence on the disorder seems to suggest that there are individuals in the world who meet all of the conditions for responsible agency that the theory (...) lays out but who are nevertheless not responsible agents. Attending to the moral psychology of such individuals will, I think, help shed light on an important gap in the conversational theory. (shrink)

Deep Brain Stimulation (DBS) is a relatively new, experimental treatment for patients suffering from treatment-refractory Obsessive Compulsive Disorder (OCD). The effects of treatment are typically assessed with psychopathological scales that measure the amount of symptoms. However, clinical experience indicates that the effects of DBS are not limited to symptoms only: patients for instance report changes in perception, feeling stronger and more confident, and doing things unreflectively. Our aim is to get a better overview of the whole variety of changes (...) that OCD patients experience during DBS treatment. For that purpose we conducted in-depth, semi-structured interviews with 18 OCD patients. In this paper, we present the results from this qualitative study.We list the changes grouped in four domains: with regard to (a) person, (b) (social) world, (c)characteristics of person-world interactions, and (d) existential stance. We subsequently provide an interpretation of these results. In particular, we suggest that many of these changes can be seen as different expressions of the same process; namely that the experience of anxiety and tension gives way to an increased basic trust and increased reliance on one’s abilities. We then discuss the clinical implications of our findings, especially with regard to properly informing patients of what they can expect from treatment, the usefulness of including CBT in treatment, and the limitations of current measures of treatment success. We end by making several concrete suggestions for further research. (shrink)

Christopher Boorse’s biostatistical theory of medical disorder claims that biological part-dysfunction (i.e., failure of an internal mechanism to perform its biological function), a factual criterion, is both necessary and sufficient for disorder. Jerome Wakefield’s harmful dysfunction analysis of medical disorder agrees that part-dysfunction is necessary but rejects the sufficiency claim, maintaining that disorder also requires that the part-dysfunction causes harm to the individual, a value criterion. In this paper, I present two considerations against the sufficiency claim. (...) First, I analyze Boorse’s central argument for the sufficiency claim, the “pathologist argument,” which takes pathologists’ intuitions about pathology as determinative of medical disorder and conclude that it begs the question and fails to support the sufficiency claim. Second, I present four counterexamples from the medical literature in which salient part-dysfunctions are considered nondisorders, including healthy disease carriers, HIV-positive status, benign mutations, and situs inversus totalis, thus falsifying the sufficiency claim and supporting the harm criterion.

This study discusses the potential of virtual reality therapy to treat traumatic experiences. It considers the main advantages of exposure therapy through virtual reality in comparison with traditional exposure therapy. In order to explain the effectiveness of using virtual reality to treat trauma, the main research question that was asked was how to conceptualize it. It was assumed that the trauma was a deviation from the normal narrative that people create for a particular crisis event. The results of the empirical (...) research prove that virtual reality therapy can be considered a powerful tool for treating traumatic experiences, as cyberspace allows reformulation of self-images, experimenting and practicing coping skills, creating a new life story, and finding meaning in certain crisis events.

Aphantasia is a condition characterised by a deficit of mental imagery. Since several psychopathologies are partially maintained by mental imagery, it may be illuminating to consider the condition against the background of psychological disorder. After outlining current findings and hypotheses regarding aphantasia and psychopathology, this paper suggests that some support for defining aphantasia as a lack of voluntary imagery may be found here. The paper then outlines potentially fruitful directions for future research into aphantasia in general and its relation (...) to psychopathology in particular, including rethinking use of the SUIS to measure involuntary imagery, whether aphantasia offers protection against addiction, and whether hyperphantasia is a potential risk factor for maladaptive daydreaming, among others.

This paper has both theoretical and practical ambitions. The theoretical ambitions are to explore what would constitute both effective and ethical treatment of Autism Spectrum Disorder.1 However, the practical ambition is perhaps more important: we argue that a dominant form of Applied Behavior Analysis, which is widely taken to be far-and-away the best “treatment”2 for ASD, manifests systematic violations of the fundamental tenets of bioethics. Moreover, the supposed benefits of the treatment not only fail to mitigate these violations, but (...) they often exacerbate them.

This paper is a critical analysis of the concept of mental disorder recently advanced by Jerome Wakefield. Wakefield suggests that mental disorders are most aptly conceived as "harmful dysfunctions" involving two distinct and separable components: the failure of the mechanism in the person to perform a natural function for which the mechanism was designed by natural selection, and a value judgment that the dysfunction is undesirable.

In this paper, my goal is to use an epistemic injustice framework to extend an existing normative analysis of over-medicalization to psychiatry and thus draw attention to overlooked injustices. Kaczmarek has developed a promising bioethical and pragmatic approach to over-medicalization, which consists of four guiding questions covering issues related to the harms and benefits of medicalization. In a nutshell, if we answer “yes” to all proposed questions, then it is a case of over-medicalization. Building on an epistemic injustice framework, I (...) will argue that Kaczmarek’s proposal lacks guidance concerning the procedures through which we are to answer the four questions, and I will import the conceptual resources of epistemic injustice to guide our thinking on these issues. This will lead me to defend more inclusive decision-making procedures regarding medicalization in the DSM. Kaczmarek’s account complemented with an epistemic injustice framework can help us achieve better forms of medicalization. I will then use a contested case of medicalization, the creation of Premenstrual Dysphoric Disorder in the DSM-5 to illustrate how the epistemic injustice framework can help to shed light on these issues and to show its relevance to distinguish good and bad forms of medicalization.

While the prevalence of opioid use disorder among pregnant women has multiplied in the United States in the last decade, buprenorphine treatment for peripartum women with OUD has been administered to reduce risks of repeated cycles of craving and withdrawal. However, the maternal behavior and bonding in mothers with OUD may be altered as the underlying maternal behavior neurocircuit is opioid sensitive. In the regulation of rodent maternal behaviors such as licking and grooming, a series of opioid-sensitive brain regions (...) are functionally connected, including the ventral pallidum. In humans, these brain regions, interact with the supplementary motor area to regulate maternal behaviors and are functionally dysregulated by opioids. It is unclear how these brain regions respond to the emotions of their child for mothers receiving BT. In this functional magnetic resonance imaging pilot study in 22 mothers within the first postpartum year, including six mothers receiving BT and 16 non-OUD mothers as a comparison group, we devised a child face mirroring task in fMRI settings to assess maternal responses to pictures of facial expressions of own child and an unknown child in an empathic mirroring condition and a non-mirroring observation condition. In each condition, faces of neutral, ambiguous, distressed, and joyful expressions of each child were repeatedly displayed in a random order. The response of SMA during empathic mirroring vs. non-mirroring of own child was reduced among BT/OUD vs. CG. Within MBN, the left VP, critical for parental sensitivity, had a similar deficit. This study outlines potential mechanisms for investigating the risks of deficits in the neural responses to actual maternal sensitivity and parenting behavior in mothers with OUD, and potential targets for interventions that reduce stress and augment maternal behavior and child outcome.

This article has two aims. The first is to introduce some novel data that highlight rather surprising pragmatic abilities in autism spectrum disorder (ASD). The second is to consider a possible implication of these data for an emerging empirical methodology in philosophy of language and mind. In pursuing the first aim, we expect our main audience to be clinicians and linguists interested in pragmatics. It is when we turn to methodological issues that we hope to pique the interest of (...) philosophers. Still, the methodological issue becomes pressing precisely because of the empirical finding—thus the first part is important for the philosophical readers as well. The game plan is as follows. Given our intended dual audience, we begin with background on autism and pragmatics. Some of this material will be familiar to some of our readership, but few will know all of it. (Those who do are invited to skip these sections.) We then present some results from our pilot study on a corpus of speech by people with ASD. The heart of our finding is that certain speakers with ASD, who have severe trouble with familiar pragmatic phenomena such as metaphor and conversational implicature, exhibit surprising abilities with respect to what is often called “pragmatic determinants of what is said.” We turn next to a possible implication of this finding: It seems to suggest that hitherto seemingly promising evidence from ASD about the semantics/pragmatics boundary is..

Externalist theories hold that a comprehensive understanding of mental disorder cannot be achieved unless we attend to factors that lie outside of the head: neural explanations alone will not fully capture the complex dependencies that exist between an individual’s psychiatric condition and her social, cultural, and material environment. Here, we firstly offer a taxonomy of ways in which the externalist viewpoint can be understood, and unpack its commitments concerning the nature and physical realization of mental disorder. Secondly, we (...) apply a strongly externalist approach to the case of Autistic Spectrum Disorder, and argue that this condition can be illuminated by appeal to the hypothesis of extended cognition. We conclude by briefly considering the significance this strongly externalist approach may have for psychiatric practice and pedagogy. (shrink)

Based on previous studies implicating increased functional connectivity within the self-referential brain network in major depressive disorder (MDD), and considering the functional roles of three distinct modules of such brain net (responsible for three-dimensional components of Selfhood) together with the documented abnormalities of self-related processing in MDD, we tested the hypothesis that patients with depression would exhibit increased connectivity within each module of the self-referential brain network and that the strength of these connections would correlate positively with depression severity. (...) Applying the electroencephalogram (EEG) operational synchrony analysis to extract three modules of the self-referential brain network in 12 medication-free depressive outpatients and 10 control subjects we have found an increase in the strength of EEG synchrony within all three modules in depressive patients (though non-significant for the right module). Furthermore, multiple regression analysis that used 3 factors (values of synchrony strength for all three modules) as input indicated that combined increase in the strength of synchrony in all three modules was positively associated with severity of depression. Taken together the findings of this study suggest that depression is primarily associated with hypersynchrony in all three modules of the brain self-referential network (the anterior module been responsible for “witnessing observation and first–person perspective”, the left posterior module been responsible for “reflective agency and narration” and the right posterior module been responsible for “bodily representational-emotional agency”), thus contributing to excessive self-focus, rumination, and body tension.

Developmental coordination disorder is a neurodevelopmental disorder that significantly impairs a child’s ability to learn motor skills and to perform everyday activities. The cause of DCD is unknown; however, evidence suggests that children with DCD have altered brain structure and function. While the cerebellum has been hypothesised to be involved in developmental coordination disorder, no studies have specifically examined cerebellar structure in this population. The purpose of our study was to examine cerebellar differences in children with DCD (...) compared to typically-developing children. Using voxel-based morphometry, we assessed cerebellar morphology in children 8–12 years of age. Forty-six children were investigated using high resolution T1-weighted images, which were then processed using the spatially unbiased atlas template of the cerebellum and brainstem toolbox for a region of interest-based examination of the cerebellum. Results revealed that children with DCD had reduced grey matter volume in several regions, namely: the brainstem, right/left crus I, right crus II, left VI, right VIIb, and right VIIIa lobules. Further, Pearson correlations revealed significant positive associations between the total motor percentile score on the Movement Assessment Battery for Children-2 and regions that had reduced grey matter volume in our cohort. These findings indicate that reductions in cerebellar grey matter volume are associated with poorer motor skills. Given the cerebellum’s involvement in internal models of movement, results of this study may help to explain why children with DCD struggle to learn motor skills. (shrink)

Attention-deficit hyperactivity disorder is one of the most common neurodevelopmental disorders in children and adolescents. People who have this disorder are characterized by presenting difficulties in the processes of sustained attention, being very active, and having poor control of their impulses. Despite the high prevalence of this disorder and the existence of various tests used for its diagnosis, few data are available regarding the usefulness and diagnostic validity of these tools. Given the difficulties that these subjects present (...) in executive functions, the aim of this study was to evaluate whether the Neuropsychological Assessment of Executive Functions battery for Children allows to establish specific profiles of executive performance for people with attention-deficit hyperactivity disorder. The sample was made up of 197 participants of both sexes, aged between 6 and 12 years age. A nonexperimental design was followed, using a comparative descriptive study method. The results indicated that the scales of phonological fluency, color path, rings, and interference are the most associated with the diagnosis of ADHD, providing data on inhibition, mental flexibility, sustained and selective attention, planning, verbal fluency, and working memory, among others. The practical implication of these results is in line with providing support in the clinical diagnosis that is carried out in children’s mental health units. In addition, the ENFEN tool can be valued as a suitable psychometric instrument in the psychoeducational field, helping professionals in a school environment to be more aware of the areas of cognitive development in which a student diagnosed with ADHD will have more difficulties and, in doing so, providing more adjusted and effective psychopedagogical measures when it comes to supporting students in their adaptation to the school environment.

In recent decades, attempts to explain autism have been frustrated by the heterogeneous nature of its behavioral symptoms and the underlying genetic, neural, and cognitive mechanisms that produce them. This has led some to propose eliminating the category altogether. The eliminativist inference relies on a conception of psychiatric categories as kinds defined by their underlying mechanistic structure. I review the evidence for eliminativism and propose an alternative model of the family of autisms. On this account, autism is a network category (...) defined by a set of idealized exemplars linked by multiple levels of theoretically significant properties. I argue that this network model better captures the empirical phenomena, the historical growth of the category, and the ways the category has been shaped by social norms and interests. Finally, I defend a realist interpretation of network categories against the challenge from eliminativists. (shrink)

The diagnostic category of borderline personality disorder (BPD) has come under increasing criticism in recent years. In this paper, we analyze the role and impact of epistemic injustice, specifically testimonial injustice, in relation to the diagnosis of BPD. We first offer a critical sociological and historical account, detailing and expanding a range of arguments that BPD is problematic nosologically. We then turn to explore the epistemic injustices that can result from a BPD diagnosis, showing how they can lead to (...) experiences of testimonial injustice which impede patient engagement in meaning-making activities, thereby undermining standard therapeutic goals. We conclude by showing how our arguments bolster ongoing efforts to replace the diagnostic category of BPD with alternatives such as complex post-traumatic stress disorder. (shrink)

Background Deep brain stimulation is approved for treating refractory obsessive-compulsive disorder in adults under the US Food and Drug Administration Humanitarian Device Exemption, and studies have shown its efficacy in reducing symptom severity and improving quality of life. While similar deep brain stimulation treatment is available for pediatric patients with dystonia, it is not yet available for pediatric patients with obsessive-compulsive disorder, although soon could be. The prospect of growing indications for pediatric deep brain stimulation raises several ethical (...) concerns relating to bodily integrity, the ability to offer informed assent, and the role pediatric patients play in the decision-making process. Objective The aim of this study is to solicit and assess the views of stakeholders (children, parents, clinicians) on pediatric assent, autonomy, and bodily integrity in the context of potential pediatric deep brain stimulation for obsessive-compulsive disorder. Methods Semi-structured interviews were conducted with pediatric obsessive-compulsive disorder patients ( n = 21), caregivers of pediatric obsessive-compulsive disorder patients aged 14–18 ( n = 19), and clinicians with experience treating refractory obsessive-compulsive disorder ( n = 25). Interviews were transcribed and coded in MAXQDA 2018 and 2020 software and processed for thematic content analysis to isolate and compare specific themes. Results A majority of respondents (74%, 48/65) across all three stakeholder groups voiced that the decision-making process should be collaborative and involve everyone (clinicians: 84% or 21/25, caregivers 71% or 15/21, and patients 63% or 12/19). We identified a split between respondents’ views on who should have the final say in the event of disagreement (38% or 25/65 favored the patient versus 35% or 23/65 favoring caregivers). A split between respondents also emerged concerning the maturity relevant for deep brain stimulation decision-making, with 45% (29/65) favoring developmental maturity (age/physiological development) and 45% (29/65) favoring decisional maturity (capacity to understand and weigh information). A majority of clinicians indicated that they would not move forward with deep brain stimulation without securing patient assent (80% or 20/25), with some stating the only exception is if patient quality of life was very poor and/or they lacked insight. Both caregivers and patients expressed a significant respect for the patient's right to bodily integrity, with 67% of caregivers (14/21) and 68% of patients (13/19) justifying patient involvement in decision-making specifically with reference to infringements of bodily integrity. Conclusion Our findings demonstrate that despite broad agreement across stakeholders that the decision-making process for pediatric deep brain stimulation for obsessive-compulsive disorder should be collaborative and somehow involve pediatric patients, there is disagreement about what this process entails and what factors determine patient involvement in the process. However, there is agreement that children have a right to bodily and brain integrity, which should only be infringed upon in rare circumstances. (shrink)

Unregulated patient treatments and approved clinical trials have been conducted with haematopoietic stem cells and mesenchymal stem cells for children with autism spectrum disorder. While the former direct-to-consumer practice is usually considered rogue and should be legally constrained, regulated clinical trials could also be ethically questionable. Here, we outline principal objections against these trials as they are currently conducted. Notably, these often lack a clear rationale for how transplanted cells may confer a therapeutic benefit in ASD, and thus, have (...) ill-defined therapeutic outcomes. We posit that ambiguous and unsubstantiated descriptions of outcome from such clinical trials may nonetheless appeal to the lay public as being based on authentic scientific findings. These may further fuel caregivers of patients with ASD to pursue unregulated direct-to-consumer treatments, thus exposing them to unnecessary risks. There is, therefore, a moral obligation on the part of those regulating and conducting clinical trials of stem cell-based therapeutic for ASD minors to incorporate clear therapeutic targets, scientific rigour and reporting accuracy in their work. Any further stem cell-based trials for ASD unsupported by significant preclinical advances and particularly sound scientific hypothesis and aims would be ethically indefensible. (shrink)

Despite numerous studies on the treatment of developmental language disorder, the intervention effect has long been debated. Systematic reviews of the effect of language therapy alone are rare. This evidence-based study investigated the effect of language therapy alone for different expressive and receptive language levels in children with DLD. Publications in databases including PubMed, the Cochrane Library, the Wanfang Database and the China National Knowledge Infrastructure were searched. Randomized controlled trials were selected. The methodological quality of the included trials (...) was assessed using the modified Jadad method. RevMan 5.3 software was used for the data analysis. Fifteen trials were included in this study. Compared with the control group, the intervention group showed significant differences in overall expressive language development [standard mean differences, 0.46; 95% confidence interval, 0.12–0.80], mean length of utterances in a language sample, number of utterances in a language sample, parent reports of expressive phrase complexity, overall expressive vocabulary development and different words used in a language sample. However, language therapy did not show satisfactory long-term effects on DLD. Although language therapy is helpful in improving the performance of children with DLD, its long-term effect is unsatisfactory. (shrink)

Cannabis use in some individuals can meaningfully introduce de novo risk for the initiation of opioid use and development of opioid use disorder. These risks may be particularly high during adolescence when cannabis use may disrupt critical periods of neurodevelopment. Current research studying the combination of genetic and environmental factors involved in substance use disorders is poorly understood. More research is needed, particularly to identify which adolescents are most at risk and to develop effective interventions addressing contributing factors such (...) as trauma and psychiatric comorbidity.

The general definition of mental disorder stated in the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders seems to identify a mental disorder with a harmful dysfunction. However, the presence of distress or disability, which may be bracketed as the presence of harm, is taken to be merely usual, and thus not a necessary requirement: a mental disorder can be diagnosed as such even if there is no harm at all. In this paper, we (...) focus on the harm requirement. First, we clarify what it means to say that the harm requirement is not necessary for defining the general concept of mental disorder. In this respect, we briefly examine the two components of harm, distress and disability, and then trace a distinction between mental disorder tokens and mental disorder types. Second, we argue that the decision not to regard the harm requirement as a necessary criterion for mental disorder is tenable for a number of practical and theoretical reasons, some pertaining to conceptual issues surrounding the two components of harm and others pertaining to the problem of false negatives and the status of psychiatry vis-à-vis somatic medicine. However, we believe that the harm requirement can be maintained among the specific diagnostic criteria of certain individual mental disorders. More precisely, we argue that insofar as the harm requirement is needed among the specific diagnostic criteria of certain individual mental disorders, it should be unpacked and clarified. (shrink)

Although not identical, this article suggests that complex posttraumatic stress disorder, depersonalization and schizophrenia share at least one feature: in all these cases, the body becomes a defective tool, an IT. In turn, those suffering from them can no longer be-in-the-world through the living body but rather experience their body as an object; they manage their lives on the level of body image.The next section outlines some cognitive and phenomenological concepts such as body schema, body image, body-as-subject and body-as-object. (...) Thereafter, the article explores the phenomenology of C-PTSD, depersonalization, and schizophrenia, finally suggesting that in each of these cases the body... (shrink)

About ten years ago, I participated in a consensus process on migraine nomenclature. Participants used a modified Delphi technique to explore their views about what migraine is. Candidate concepts included an illness, disease, syndrome, condition, disorder, or susceptibility. Initially, there was a wide range of views about which concept best fits our concept of migraine. Migraine—in common with many psychiatric disorders—is poorly understood by neuroscience. On scientific grounds, participants thought that "susceptibility" and "syndrome" describes our current knowledge well. However, (...) participants were concerned that terms like "susceptibility" and "syndrome" could lead to migraine not... (shrink)

The dominant philosophical conceptions of obsessive-compulsive behavior present its subject as having a deficiency, usually characterized as volitional, due to which she lacks control and choice in acting. Compulsions (mental or physical) tend to be treated in isolation from the obsessive thoughts that give rise to them. I offer a different picture of compulsive action, one that is, I believe, more faithful to clinical reality. The clue to (most) obsessive-compulsive behavior seems to be the way obsessive thoughts, which are grounded (...) in an irrational cognitive style in matters of risk, danger, and responsibility, motivate compulsions through bizarre means–end reasoning. I show that the patient with obsessive-compulsive disorder (OCD) is not weak and passive with regard to the compulsive act; rather, the act is voluntary and regarded by the patient as an instrument of control. I also defend the idea that OCD-related cognitions are either beliefs or mental states with relevantly similar functional roles. (shrink)

AbstractAdvances in precision agriculture, driven by big data technologies and machine learning algorithms can transform agriculture by enhancing crop and livestock productivity and supporting faster and more accurate on and off-farm decision making. However, little is known about how PA can influence farmers’ sense of self, their skills and competencies, and the meanings that farmers ascribe to farming. This study is animated by scholarly commitment to social identity research, and draws from socio-cyber-physical systems research, domestication theory, and activity theory. This (...) conceptualization of PA within these theoretical perspectives helps to render visible how big agricultural data and machine learning algorithms can affect meaning, doing, and being for US farmers. Through analysis of data from six focus group discussions and follow-up surveys with stakeholders across the PA value chain, this paper shows that PA tools can necessitate farmers to learn and develop new competencies such as flying drones and interpreting yield maps. At the same time, PA can shape new meaning of farm work and new expectation about a ‘good farmer’, changing what it means to be a ‘successful’ farmer from someone who is not only a data observer or data gatherer but also validators of PA models by using their local knowledge of agronomic and environmental phenomenon. We conclude that PA can alter social expectations about farming by reorienting the role of farmers. Policymakers and agriculture extension and outreach programmers can develop more socially relevant PA knowledge and innovation if they can attend to both new and traditional ‘good farmer’ identities.

PurposeThe purpose of this study is to describe the implementation and outcomes of an Eye Movement and Desensitization Reprocessing treatment-program for women with posttraumatic stress disorder after childbirth.MethodsA prospective cohort-study with pre- and post-measurements was carried out in the setting of an academic hospital in the Netherland. Included were women who gave birth to a living child at least 4 weeks ago, with a diagnosis of PTSD, or severe symptoms of PTSD combined with another psychiatric diagnosis. All received up (...) to 8 sessions of EMDR-therapy. The posttraumatic stress disorder Checklist for DSM-5 was administered before and after treatment. Trauma history was assessed before treatment with the Life Events Checklist for the DSM-5, the Childhood Trauma Questionnaire and the Childbirth Perception Scale. Descriptive statistics were used.ResultsForty-four women were referred, 26 met the inclusion criteria. After treatment, none of the women met the criteria for diagnosis of PTSD after on average 5 weekly sessions of EMDR- therapy. These outcomes are promising, as they were achieved in women with relatively high levels of psychiatric comorbidity and high rates of previous mental health treatment.ConclusionImplementing an EMDR-treatment program for women with PTSD after childbirth in the setting of an academic hospital is feasible and effective. Key factors for success include a close collaboration between the relevant hospital departments and a thorough case conceptualization addressing the etiology of the PTSD. (shrink)

The end-state comfort effect refers to the consistent tendency of healthy adults to end their movements in a comfortable end posture. In children with and without developmental coordination disorder, the results of studies focusing on ESC planning have been inconclusive, which is likely to be due to differences in task constraints. The present pilot study focused on the question whether children with and without DCD were able to change their planning strategy and were more likely to plan for ESC (...) when demanded by complex object manipulations at the end of a task. To this end, we examined ESC planning in 18 children with and without DCD using the previously used sword-task and the newly developed hammer-task. In the sword-task, children had to insert a sword in a wooden block, which could be relatively easily completed with an uncomfortable end-posture. In the hammer-task, children had to strike down a nail in a wooden pounding bench, which required additional force and speed demands, making it relatively difficult to complete the movement with an uncomfortable end-posture. In line with our hypothesis, the results demonstrated that children with and without DCD were more likely to plan for ESC on the hammer-task compared with the sword-task. Thus, while children with and without DCD show inconsistent ESC planning on many previously used tasks, the present pilot study shows that many of them are able to take into account the end-state of their movements if demanded by task constraints.

Emotions might contribute to our being rational cognitive agents. Anxiety – and more specifically epistemic anxiety – provides an especially interesting case study into the role of emotion for adaptive cognition. In this paper, I aim at clarifying the epistemic contribution of anxiety, and the role that ill-calibrated anxiety might play in maladaptive epistemic activities which can be observed in psychopathology. In particular, I argue that this emotion contributes to our ability to adapt our cognitive efforts to how we represent (...) the practical factors relevant to the task at hand, by sig- naling the need for increased cognitive processing and evidence gathering in high- stakes situations. I hypothesize that dysfunctional or ill-calibrated epistemic anxiety might play an important role in the motivation driving persons with obsessive- compulsive disorder (OCD) to invest high amounts of cognitive resources into the resolution of apparently simple and innocuous questions. As I argue, OCD might be conceived as a case in which epistemic anxiety is inappropriately elicited, represent- ing these as high-stakes questions, and inadequately signaling a need for cognition. In this paper, I thus make use of the concept of (epistemic) anxiety as developed in the philosophy of emotion and in epistemology, to propose an account of the role of anxiety in the pathological doubt that is central to obsessive-compulsive disorder.

Eye movement desensitization and reprocessing therapy is a well-established therapeutic method to treat post-traumatic stress disorder. However, how EMDR exerts its therapeutic action has been studied in many types of research but still needs to be completely understood. This is in part due to limited knowledge of the neurobiological mechanisms underlying EMDR, and in part to our incomplete understanding of PTSD. In order to model PTSD, we used a biologically inspired computational model based on firing rate units, encompassing the (...) cortex, hippocampus, and amygdala. Through the modulation of its parameters, we fitted real data from patients treated with EMDR or classical exposure therapy. This allowed us to gain insights into PTSD mechanisms and to investigate how EMDR achieves trauma remission. (shrink)

This study explores the emergence and productivity of word order usage in Mandarin-speaking typically-developing children and children with autism spectrum disorder, and examines how this emergence relates to frequency of use in caregiver input. Forty-two caregiver-child dyads participated in video-recorded 30-min semi-structured play sessions. Eleven children with ASD were matched with 10 20-month-old TD children and another 11 children with ASD were matched with 10 26-month-old TD children, on expressive language. We report four major findings: Preschool Mandarin-speaking children with (...) ASD produced word order structures with pervasive ellipsis at similar rates to language-matched TD children, but also displayed differences from TD children in their usage of SVt and VtO frames; Grammatical productivity was observed in both TD children and children with ASD; moreover, children with ASD with higher expressive language produced less stereotyped language; Both TD children and children with ASD heard a range of word orders in their caregivers’ input, with TD children’s input greater in amount and complexity; however, caregivers of both groups also showed no age/language-related changes in word order usage; Few word-order-specific correlations emerged between caregivers and their children; however, strong correlations were observed for mean length of utterances for both groups: Caregivers who produced longer/more complex utterances had children who did the same. Taken together, it seems that despite their pragmatic deficits, the early grammatical knowledge of word order in Mandarin-exposed children with ASD is well preserved and in general follows the typical developmental pattern. Moreover, caregiver input is broadly rather than finely tuned to the linguistic development of TD children and children with ASD, and plays a more important role in children’s general syntactic development than in specific word order acquisition. Thus, early word order usage in preschool Mandarin-speaking TD children and children with ASD may be influenced by both caregiver input and child abilities. (shrink)

This article discusses a puzzle arising from the phenomenon of insight in obsessive–compulsive disorder. “Insight” refers to an awareness or understanding of obsessive thoughts as false or irrational. I argue that a natural and plausible way of characterizing insight in OCD conflicts with several different possible explanations of the epistemic attitude underlying insight‐directed obsessive thought. After laying out the puzzle for five proposed explanations of obsessive thought and then discussing several possible ways that the puzzle might be avoided, I (...) close the article by arguing that we can avoid the puzzle by adopting a new positive view of insight‐directed obsessive thought.
