Maladapting Minds discusses a number of reasons why philosophers of psychiatry should take an interest in evolutionary explanations of mental disorders and, more generally, in evolutionary thinking. First of all, there is the nascent field of evolutionary psychiatry. Unlike other psychiatrists, evolutionary psychiatrists engage with ultimate, rather than proximate, questions about mental illnesses. Being a young and youthful new discipline, evolutionary psychiatry allows for a nice case study in the philosophy of science. Secondly, philosophers of psychiatry have engaged with evolutionary (...) theory because evolutionary considerations are often said to play a role in defining the concept of mental disorder. The basic question here is: Can the concept of mental disorder be given an objective definition, or is it rather a normative concept? Thirdly and finally, evolutionary thinking in psychiatry has often been a source of inspiration for a philosophical view on human nature. Thus evolutionary psychiatrists have suggested, for example, that man's vulnerability to mental disorders may well be one of the defining features of our species. -/- Written by leading authors in philosophy, psychiatry, biology and psychology, this volume illustrates that many debates in contemporary philosophy of psychiatry are profoundly influenced by evolutionary approaches to mental disorders. Conversely, it also reveals how philosophers can help contribute to the burgeoning field of evolutionary psychiatry. It is important reading for a wide range of readers interested in mental health care and philosophy. (shrink)

Veissière and collaborators ground their account of culture and social norms in the free-energy principle, which postulates that the utility of an outcome is equivalent to its probability. This equivalence would mean that their account entails that complying with social norms has always adaptive value. But, this is false, because many social norms are obviously maladaptive.

During the COVID-19 outbreak, individuals with or without mental disorders may resort to dysfunctional psychological strategies that could trigger or heighten their emotional distress. The current study aims to explore the links between maladaptive daydreaming, psychological symptoms of depression, anxiety, and negative stress, and COVID-19-related variables, such as changes in face-to-face and online relationships, during the COVID-19 lockdown in Italy. A total of 6,277 Italian adults completed an online survey, including socio-demographic variables, COVID-19 related information, the 16-item Maladaptive Daydreaming Scale, (...) and Depression, Anxiety, and Stress Scales-21 Items. Based on an empirically derived cut-off score, 1,082 participants were identified as probable maladaptive daydreamers. A binary logistic regression revealed that compared to controls, probable MDers reported that during the COVID-19 lockdown they experienced higher levels of anxiety and depression, decreased online social relationships, and, surprisingly, stable or increased face-to-face social relationships. Given the peculiar characteristics of the pandemic context, these findings suggest that the exposure to the risk of contagion had probably exacerbated the tendency of probable MDers to lock themselves inside their mental fantasy worlds, which in turn may have contributed to further estrangement from online social relationships and support, thus worsening their emotional distress.

Background: The literature has shown a significant association between traumatic experiences and eating psychopathology, showing a greater symptomatology in patients with trauma history. Less is known about the associations between trauma and cognitive schemas, and personality traits and the differences between childhood and adulthood trauma experiences. Thus, this paper aims to assess the clinical and psychological characteristics of eating disorder (ED) patients, looking for differences between patients without a history of trauma and patients with trauma experiences, as well as at (...) possible differences between exposure in childhood, adulthood, or repeated events. Another aim of the paper is to evaluate the possible mediation role of cognitive schemas and personality traits in the relationship between early trauma and eating psychopathology.Methods: From January to November 2020, 115 consecutive inpatients admitted for a specific multidisciplinary ED treatment in a dedicated Unit were evaluated for trauma, differentiating between trauma occurring in childhood and adulthood. The subjects were evaluated for early maladaptive schemas (EMS), personality traits, trauma symptomatology, quality of life, and specific psychopathologies linked to EDs. Mediation analyses between childhood and adulthood trauma and eating psychopathology were performed, with EMS and personality traits as mediators.Results: Patients with a history of trauma showed higher physical and psychological symptomatology scores, with a more impaired clinical profile in patients with both childhood and adulthood trauma exposure. The mediation analysis showed a specific mediator role for the “disconnection and rejection (DR)” EMS factor in the relationship between childhood trauma (cT) and eating psychopathology.Conclusion: Trauma experiences are associated with more severe clinical symptomatology in EDs and may need a specific assessment in patients with failed outpatient standard treatments. Specific cognitive schemas linked to DR domain should be evaluated in treatments for ED patients with history of trauma due to the mediation role between trauma and eating psychopathology. The need for outcome studies about treatment approaches for ED patients with history of trauma is discussed. (shrink)

Human beings, like other organisms, are the products of evolution. Like other organisms, we exhibit traits that are the product of natural selection. Our psychological capacities are evolved traits as much as are our gait and posture. This much few would dispute. Evolutionary psychology goes further than this, claiming that our psychological traits -- including a wide variety of traits, from mate preference and jealousy to language and reason -- can be understood as specific adaptations to ancestral Pleistocene conditions. In (...) Evolutionary Psychology as Maladapted Psychology, Robert Richardson takes a critical look at evolutionary psychology by subjecting its ambitious and controversial claims to the same sorts of methodological and evidential constraints that are broadly accepted within evolutionary biology. The claims of evolutionary psychology may pass muster as psychology; but what are their evolutionary credentials? Richardson considers three ways adaptive hypotheses can be evaluated, using examples from the biological literature to illustrate what sorts of evidence and methodology would be necessary to establish specific evolutionary and adaptive explanations of human psychological traits. He shows that existing explanations within evolutionary psychology fall woefully short of accepted biological standards. The theories offered by evolutionary psychologists may identify traits that are, or were, beneficial to humans. But gauged by biological standards, there is inadequate evidence: evolutionary psychologists are largely silent on the evolutionary evidence relevant to assessing their claims, including such matters as variation in ancestral populations, heritability, and the advantage offered to our ancestors. As evolutionary claims they are unsubstantiated. Evolutionary psychology, Richardson concludes, may offer a program of research, but it lacks the kind of evidence that is generally expected within evolutionary biology. It is speculation rather than sound science -- and we should treat its claims with skepticism. (shrink)

Dissociation is the psychological aspect of stress response. It is an adaptive reaction to a stressor on a short-term basis but can be maladaptive if under- or overutilized and comprises the partitioning of consciousness, ranging from barely to rigidly partitioned. Current means of measuring dissociation focus primarily on DSM-IV-TR Dissociative Disorders and do not sufficiently account for adaptive sub-clinical forms or maladaptive under-dissociating. These measures of pathology are not useful for determining how well-adapted a population is to stress– i.e., how (...) well dissociation is generally put to use. The purpose of this paper is: (1) to analyze the general population and university student studies that have been conducted using current epidemiological methods of assessing dissociation in sub-clinical populations; and (2) to compare and contrast anthropological and epidemiological models of dissociation. An alternative method for assessing dissociation that synthesizes these two views is proposed. (shrink)

Open peer commentary on the target article “How and Why the Brain Lays the Foundations for a Conscious Self” by Martin V. Butz. Excerpt: There are circumstances when anticipation can be maladaptive. In the following paragraphs, the occurrence of maladaptive anticipation will be illustrated in reference to psychological disorders (depression, generalised anxiety disorder, social phobia). It will be shown that anticipation does not always lead to improved control of oneself and the environment and that anticipation is not always beneficial. Finally, (...) the question is raised of whether it is the strength of the anticipatory drive or the content of the anticipations that is the important factor in the development and construction of the self.

Empirical research has shown that maladaptive perfectionism may lead to lower life satisfaction. However, the relationship between maladaptive perfectionism and life satisfaction among medical students and the mechanism underlying this relationship still need to be further explored. The present study used a large sample of undergraduate medical students to examine the associations between maladaptive perfectionism and life satisfaction and to explore the mechanism underlying the associations. Specifically, the present study tried to probe the mediating role of academic burnout and the (...) moderating role of self-esteem in the relationship between maladaptive perfectionism and life satisfaction in medical students. We invited 1628 undergraduate medical students from two medical universities in Northeastern China to participate in the survey. Among the students recruited, 1377 medical students completed questionnaires including the Frost Multidimensional Perfectionism Scale maladaptive perfectionism subscales, the Chinese College Student Academic Burnout Inventory, the Satisfaction With Life Scale, the Rosenberg Self-Esteem Scale and demographic information. Results show that maladaptive perfectionism was significantly negatively related to life satisfaction among medical students and academic burnout played a significant mediating role in this relationship. Moderated mediation analyses reveal that the mediating effect of maladaptive perfectionism on life satisfaction via academic burnout was moderated by self-esteem. Maladaptive perfectionism exerted a stronger effect on life satisfaction via the mediating role of academic burnout for medical students with high self-esteem [β = −0.026, SE = 0.009, 95%CI = ] than for medical students with low self-esteem [β = −0.019, SE = 0.009, 95%CI = ]. Medical institutions can implement effective interventions to decrease medical students’ maladaptive perfectionism levels and academic burnout levels, and increase their self-esteem levels in order to enhance their life satisfaction.

Medical explanations of socially maladaptive behaviors most often involve an appeal to neuro-physiological models. One consequence of the appeal to such models is a lack of attention to the social character of the behaviors. It is, I argue, the social character of the behaviors that, even accepting a neuro-physiological etiology, makes classification and, hence, explanation of these disorders controversial and suspect. At the heart of the problem is the difficulty, resulting from the social aspects of the disorder, in fulfilling the (...) logical conditions of the analogical arguments employed in the explanations. The theoretical points of the paper are illustrated by a discussion of hyperactivity. CiteULike Connotea Del.icio.us What's this? (shrink)

The docility hypothesis holds that human social learning produces genuinely altruistic behaviors as a maladaptive by-product. This article examines five possible sources of such altruistic mistakes. The first two mechanisms, the smoke-detector principle and the cost-accuracy tradeoff, are not specifically linked to social learning. Both predict that it may be adaptive for cooperators to allow some altruistic mistakes to happen, as long as those mistakes are rare and cost little. The other three mechanisms are specific to social learning: Through culture, (...) individuals may come to adopt altruistic norms selected at the group level. Culture may provide people with cheap, accessible, but occasionally mediocre information that they are too reliant upon—a kind of informational dumping. Lastly, people may copy sources good to follow in one domain but not in another, thus committing calibration errors. I argue that those sources of errors are unlikely to lead to important amounts of altruism toward non-kin. Experimental evidence shows humans to be sufficiently skeptical, discriminative, and conscious of their own interest to avoid such altruistic mistakes in most cases. Docile altruism is unlikely to be an important aspect of human cooperation. (shrink)

Consciousness, as a higher-order cognitive capacity allowing for the explicit representation of abstract mental states, might be the incidental byproduct of design features from other adaptive systems, such as those governing expansion of the frontal lobes in primates. Although such abilities may have occurred entirely by chance, the standardized entrenchment of this representational capacity in human cognition may have posed engineering dilemmas for natural selection in that consciousness could not be easily removed without disrupting the adaptive features of other design (...) solutions. If so, then those organisms saddled with the burden of higher-order representation by the occurrence of these chance events were suddenly assaulted with a series of social problems previously unencountered by any other species in evolutionary history. Such consciousness-based problems constituted enormous selective pressure for generating ancestrally adaptive psychological programs designed to cope with them. Each of these design solutions was, by necessity, generated and progressively pruned over an extraordinarily short span of geological time. In addition, these programs ran into conflict with more ancient primate social adaptations — such as those underlying sexual coercion and violence — that did not evolve to be sensitive to the epistemic positions of others. These mosaic processes have likely resulted in selection for innumerable algorithmic properties driving human-specific behaviors which are both proximally and ultimately caused by consciousness. Consciousness by itself should be classified as maladaptive; what is adaptive are those psychological programs in place to support its incidental and problematic arrival in the human brain. (shrink)

Rumination is associated with psychological adjustment and WM capacity. Studies have shown that psychological interventions such as expressive writing can reduce negative rumination and improve WM capacity. The present study investigated the effect of positive rumination training in expressive writing on psychological adjustment and WM updating. Within an experimental design, positive rumination was manipulated for 10 participants who were maladaptive ruminators in an experiment using a five week training compared to the control group with 9 participants. Results revealed significant enhancement (...) of psychological adjustment and the response time (RT) of WM updating in the experimental group but not in the control group. The two groups did show signifcant difference of all the outcomes in pretest. But the experimental group showed significantly better oucomes than the control group in posttest. The results indicate that positive rumination training in expressive writing is effective and rumination has a causal influence on WM updating capacity. (shrink)

ObjectiveApproximately half of all people living with amyotrophic lateral sclerosis experience persistent or recurrent emotional distress, yet little is known about the psychological processes that maintain emotional distress in this population. The self-regulatory executive functioning model specifies that maladaptive metacognitive beliefs and processes are central to the development and maintenance of emotional distress. This study explored whether maladaptive metacognitive beliefs are associated with emotional distress after controlling for demographic factors, time since diagnosis, and current level of physical functioning.DesignIn a cross-sectional (...) design, 75 adults with a diagnosis of ALS completed self-report questionnaires. Participants had a mean age of 60.40 years, mean duration of symptoms 63.92 months, and male:female gender ratio of 14:11.Main Outcome MeasuresQuestionnaires assessed emotional distress, physical functioning, repetitive negative thinking, metacognitive beliefs, and demographic factors.ResultsMaladaptive metacognitive beliefs explained additional variance in emotional distress after controlling for age, gender, time since diagnosis, physical functioning, and repetitive negative thinking. Repetitive negative thinking partially mediated the relationships between positive and negative metacognitive beliefs and emotional distress.ConclusionsThese data support the utility of the metacognitive model in understanding emotional distress in people with ALS. Examination of the temporal relationship between maladaptive metacognitive beliefs and emotional distress in people living with ALS may help to guide the development of therapeutic approaches.

Research has revealed that child abuse experience can increase pathological Internet use; however, few studies have focused on the influence of child abuse experience on pathological Internet use. This study examined the mediating roles of security and maladaptive cognitions in the association between child abuse and pathological Internet use. A total of 918 Chinese university students participated in the study, with measurements of child abuse, security, maladaptive cognitions, and pathological Internet use being employed. Structural equation modeling results indicated that child (...) abuse could positively predict pathological Internet use, pathological Internet use through the mediating role of security, pathological Internet use through the mediating role of maladaptive cognitions, and pathological Internet use through the chain mediating role of security and maladaptive cognitions. These results indicated that security and maladaptive cognitions were the primary factors in the association between child abuse and pathological Internet use. (shrink)

In his ‘script theory,' Tomkins first proposed that people unconsciously organize their life experiences in terms of narrative structures he termed “scripts.” I use a clinical vignette to illustrate how the psychotherapeutic process of “making the unconscious conscious” involves becoming aware of the maladaptive scripts that people unwittingly live by, and developing them into the “conviction narratives” proposed by the authors.

ABSTRACTAlthough social anxiety symptoms are robustly linked to biased self-evaluations across time, the mechanisms of this relation remain unclear. The present study tested three maladaptive emotion regulation strategies – state post-event processing, state experiential avoidance, and state expressive suppression – as potential mediators of this relation. Undergraduate participants rated their social skill in an impromptu conversation task and then returned to the laboratory approximately two days later to evaluate their social skill in the conversation again. Consistent with expectations, state post-event (...) processing and state experiential avoidance mediated the relation between social anxiety symptoms and worsening self-evaluations of social skill, particularly for positive qualities. State expressive suppression did not mediate the relation between social anxiety symptoms and cha... (shrink)

The Dark Triad traits—narcissism, Machiavellianism and psychopathy—have been found to be associated with intra- or interpersonal deception production frequency. This cross-sectional study ( N = 207) investigated if the Dark Triad traits are also associated with deception detection accuracy, as implicated by the recent conception of a deception-general ability. To investigate associations between maladaptive personality space and deception, the PID-5 maladaptive personality traits were included to investigate if besides Machiavellianism, Detachment is negatively associated with response bias. Finally, associations between the (...) Dark Triad traits, Antagonism, Negative Affectivity and confidence judgments were investigated. Participants watched videos of lying vs. truth-telling senders and judged the truthfulness of the statements. None of the Dark Triad traits was found to be associated with the ability to detect deception. Detachment was negatively associated with response bias. Psychopathy was associated with global confidence judgments. The results provide additional support that dark and maladaptive personality traits are associated with judgmental biases but not with accuracy in deception detection. The internal consistencies of 4 of the 8 subscales of the used personality short scales were only low and nearly sufficient (αs =0.65–0.69). (shrink)

BackgroundPrevious studies have not investigated the role of resilience and coping style on the association between maladaptive perfectionism and academic procrastination among nursing undergraduates. However, how to mobilize the learning enthusiasm of nursing students and reduce the incidence of academic procrastination is an important factor to reduce nursing loss and improve nursing quality.ObjectivesTo investigate the influence of maladaptive perfectionism, resilience and coping style on academic procrastination among Chinese undergraduate nursing students.MethodsA cross-sectional study was conducted. A convenience sampling method was used (...) to select 665 nursing undergraduates from March to May 2022 in China. Maladaptive perfectionism, coping style, resilience, and academic procrastination were measured using questionnaires. The descriptive analysis, Pearson’s correlation analysis and the Hayes’ PROCESS Macro in SPSS 25.0 were used to test the model.ResultsThe results showed that nursing undergraduates’ maladaptive perfectionism, resilience, positive coping style and academic procrastination were significantly correlated between every two variables, with coefficients ranging between −0.290 and 0.584. In addition, resilience played a partial mediating role in maladaptive perfectionism and academic procrastination, accounting for 15.70% of the total effect; in the meantime, this process was moderated by positive coping style.ConclusionMaladaptive perfectionism positively predicted nursing undergraduates’ academic procrastination; as a mediating mechanism with moderating, resilience and positive coping style further explained how maladaptive perfectionism promoted the academic procrastination of nursing undergraduates. Understanding this mechanism is of great significance for nursing educators to reduce the risk of academic procrastination in nursing undergraduates. (shrink)

The negative impact of the COVID-19 pandemic on individuals’ psychosocial functioning was widely attested during the last year. However, the extent to which individual differences are associated with adaptive and maladaptive outcomes during quarantine in Italy remains largely unexplored. Using a person-oriented approach, the present study explored the association of personality profiles, based on three broad individual dispositions and two self-efficacy beliefs in the emotional area, with adaptive and maladaptive outcomes during the first Italian lockdown. In doing so, we focused (...) also on how different age groups differently faced the pandemic. The study was conducted through an online survey from May to June 2020 and included 1341 participants living in Italy, divided into two groups: 737 young adults aged 18–35 and 604 adults aged 36–60 years old. Latent Profile Analysis identified three personality profiles: resilient, vulnerable, and moderate. A subsequent path analysis model showed that the resilient profile was positively associated with prosocial behavior as an indicator of adaptive outcome, and negatively associated with three maladaptive outcomes: interpersonal aggression, depressive symptoms, and anxiety problems. Contrarily, the vulnerable profile resulted negatively associated with prosocial behavior and positively associated with the three maladaptive outcomes. Finally, regarding age group differences, young adults belonging to the vulnerable profile showed a greater association especially with interpersonal aggression, depression, and anxiety problems, as compared to adults belonging to the same profile. Overall, the results of the present study highlighted the importance to analyze individual functioning during an isolation period by using a person-oriented approach. Findings evidenced the existence of three different profiles and subsequent path analysis revealed, especially for the vulnerable profile and young adults, a greater maladaptive consequence of the quarantine. The practical implications will be discussed. (shrink)

Neuromodulatory effects of non-invasive brain stimulation (NIBS) have been extensively studied in chronic pain. A hypothetic mechanism of action would be to prevent or revert the ongoing maladaptive plasticity within the pain matrix. In this review, the authors discuss the mechanisms underlying the development of an abnormal plasticity in patients with chronic pain and the putative mechanisms of NIBS in modulating synaptic plasticity in neuropathic pain conditions.

Inflammatory bowel disease is chronic and incurable. Imperious diarrhea, rectal bleeding, fatigue, and weight loss, the main manifestations, cause a decrease in the quality of the patient’s personal and professional life. The objectives of this study were to identify a possible relationship between early maladaptive schemas and disease activity status using logistic regression, to identify the prevalence of early maladaptive schemes in patients and to propose a psychotherapeutic intervention plan. The following were found in a sample of 46 patients aged (...) 16–76 years. An increase in the domain overvigilance and inhibition score had a significant effect, with an increase of 1.137 CI95% [1.031, 1.254] of the risk of the disease being diagnosed as active. High and very high scores were observed for the emotional deprivation scheme and dependence/incompetence, vulnerability to harm and illness and subjugation schemas. The results show that the proposed model could predict and reconfirm the diagnosis; patients have specific psychotherapeutic needs. The therapeutic goal would be to offer care, empathy and protection, to strengthen self-confidence, to make patients realize that they have the ability to cope, to provide permission, encourage the patient to experiment, and guide the patient to express their anger healthily. The therapy scheme’s intervention could lead to increased long-term disease management capacity and, consequently, reduce costs directly and indirectly caused by this condition. (shrink)

In the context of English as a Foreign Language, burnout study dominantly revolves around teachers but learners’ academic burnout is largely underexplored. Academic burnout is a concerning issue worldwide that is particularly predicted by academic motivation. However, we know little about the association between motivation and burnout among EFL learners and whether maladaptive emotion regulation strategies could moderate their association. To fill this research gap, we recruited 841 EFL undergraduates from two universities in China. Descriptive analysis showed that participants reported (...) high levels of language learning burnout. Correlational and bootstrapped moderation analysis found that motivation and maladaptive ERS were significantly correlated with burnout in opposite directions and the correlation between motivation and burnout was significantly influenced by students’ use of two maladaptive ERS. The more frequently students chose to avoid and vent unpleasant feelings, the protective role of motivation on burnout was weaker. The implications of these findings are discussed. (shrink)

The increasing role that new technologies play in intimate relationships has led to the emergence of a new form of couple violence, cyber dating abuse, especially among adolescents and young adults. Although this phenomenon has received increased attention, no research has investigated predictors of cyber dating abuse taking into account the interdependence of the two partners. The study examines adverse childhood experiences and early maladaptive schemas as possible predictors of young adults’ perpetrated and suffered cyber dating abuse. Adopting a dyadic (...) approach, mediational models in which adverse childhood experiences were assumed to be related to individual and partner’s cyber dating abuse through individual early maladaptive schemas were tested. 134 couples completed online self-reports of the variables of interest, including a bidimensional measure of cyber dating abuse assessing pressure-aggression and control-monitoring. Actor-partner interdependence mediation model analyses were conducted. Results indicated that the emotional deprivation schema mediated the association between adverse childhood experiences and cyber dating abuse, whereas the abandonment schema did not. Specifically, more frequent experiences of emotional abuse and physical neglect during childhood were indirectly related to increased likelihood of perpetrating cyber dating pressure-aggression as well as of perpetrating and suffering cyber dating control-monitoring in both males and females. These associations were mediated by a stronger internalization of the emotional deprivation schema and were supported by both self-reported and partner-reported data. Also, a strong and direct association was found between childhood exposure to intimate partner violence by the opposite-sex parent and cyber dating pressure-aggression by females or control-monitoring by both males and females. These findings help to clarify the potential negative effects of specific adverse childhood experiences and early maladaptive schemas on the tendency to perpetrate and suffer cyber abuse in romantic relationships. The implications for prevention and treatment programs are noted and avenues for future research are described. (shrink)

While infant fearfulness, and its expression via crying, may have been adaptive in our evolutionary history, for modern parents, crying can be challenging to respond to. We discuss how and why prolonged crying can raise the risk for difficulties with adult care. Given that crying is the most-reported trigger for shaking, its potential to elicit maladaptive responses should not be overlooked.

The present study examined the longitudinal association among the Big Five personality traits, maladaptive cognitions, and Internet addiction during the COVID-19 pandemic. A total of 481 Chinese university students were surveyed three times by using the Chinese version of the Big Five Personality Traits Scale, Maladaptive Cognitions Scale, and Internet Addiction Scale. The results of a cross-lagged panel analysis highlighted that extraversion, agreeableness, conscientiousness, and openness were negatively associated with maladaptive cognitions and Internet addiction, whereas neuroticism was found to be (...) positively associated with maladaptive cognitions and Internet addiction across time; associations among the Big Five personality traits, maladaptive cognitions, and Internet addiction were dynamic and bidirectional; and maladaptive cognitions played mediating roles in extraversion, agreeableness, conscientiousness, openness, and Internet addiction across time. The Big Five personality traits, maladaptive cognitions, and Internet addiction predicted each other across time, and maladaptive cognitions were likely to be the key mediating factor in the associations between the Big Five personality traits and Internet addiction, which supported and expanded the Davis’ cognitive–behavioral model.
