I explore, from a proof-theoretic perspective, the hierarchy of classical and paraconsistent logics introduced by Barrio, Pailos and Szmuc in (Journal o f Philosophical Logic,49, 93-120, 2021). First, I provide sequent rules and axioms for all the logics in the hierarchy, for all inferential levels, and establish soundness and completeness results. Second, I show how to extend those systems with a corresponding hierarchy of validity predicates, each one of which is meant to capture “validity” at a different inferential level. Then, (...) I point out two potential philosophical implications of these results. (i) Since the logics in the hierarchy differ from one another on the rules, I argue that each such logic maintains its own distinct identity (contrary to arguments like the one given by Dicher and Paoli in 2019). (ii) Each validity predicate need not capture “validity” at more than one metainferential level. Hence, there are reasons to deny the thesis (put forward in Barrio, E., Rosenblatt, L. & Tajer, D. (Synthese, 2016)) that the validity predicate introduced in by Beall and Murzi in (Journal o f Philosophy,110(3), 143–165, 2013) has to express facts not only about what follows from what, but also about the metarules, etc. (shrink)

Bilateralism is the view that the speech act of denial is as primitive as that of assertion. Bilateralism has proved helpful in providing an intuitive interpretation of formalisms that, prima facie, look counterintuitive, namely, multiple-conclusion sequent calculi. Under this interpretation, a sequent of the form $\Gamma \vdash \Delta$ is regarded as the statement that it is incoherent, according to our conversational norms, to occupy the position of asserting all the sentences in $\Gamma$ and denying all the sentences in $\Delta$. Some (...) have argued, based on this interpretation, that the notion of invalidity is as conceptually primitive and important as the notion of validity: whereas the latter is couched in terms of what positions are incoherent and hence untenable, the former is couched in terms of what positions are coherent and hence tenable. My ultimate goal in this paper is to contest this view. Based on a novel technical account of the two notions—one that I find more accurate than the existing accounts in the literature—I shall argue that the notion of incoherence takes conceptual priority over the notion of coherence.

To assess whether and how environmental values and sense of place relate to sustainable farming practices, we conducted a study in South Kona, Hawaii, addressing environmental values, sense of place, and farm sustainability in five categories: environmental health, community engagement and food security, culture and history, education and research, and economics. We found that the sense of place and environmental values indexes showed significant correlation to each category of sustainability in both independent linear regressions and multivariate regression. In total, sense (...) of place explained a larger share of the overall farm performance. However, each indicator showed relative strengths; environmental values showed significantly higher correlation to environmental and educational practices. Furthermore the scales were complimentary, and the use of both scales greatly improved prediction of good farming practices from a multiple-impact perspective. With implications for community and environmental impacts, results suggest that a more comprehensive view of farmers’ environmental values and place connections may help illuminate individual farmers’ decisions and sustainability-related practices.

Minimally inconsistent LP (MiLP) is a nonmonotonic paraconsistent logic based on Graham Priest's logic of paradox (LP). Unlike LP, MiLP purports to recover, in consistent situations, all of classical reasoning. The present paper conducts a proof-theoretic analysis of MiLP. I highlight certain properties of this logic, introduce a simple sequent system for it, and establish soundness and completeness results. In addition, I show how to use my proof system in response to a criticism of this logic put forward by JC (...) Beall. (shrink)

ABSTRACTIn this study, we developed a cognitive bias modification procedure that targets inferential style, and tested its effect on hope, mood, and self-esteem. Participants were randomly assigned to training conditions intended to encourage either a negative or a positive inferential style. Participants’ inferences for their failure on a cognitive challenge were congruent with their training condition. Moreover, compared to participants in the positive training condition, those in the negative condition reported less hope and exhibited lower mood and self-esteem following the (...) failure. Finally, the training affected mood and self-esteem indirectly via its effect on participants’ inferences for their failure. These findings provide support for the causal role of inferential style in depressed affect. (shrink)

This special issue examines the diverse realities created by the intersection of emerging technologies, new scientific knowledge, and the human being. It engages with two key questions: how is the human being shaped and constructed in new ways through advances in science and technology? and how might these new ways of imagining the subject shape present and future human rights law and practice? The papers examine a variety of scientific technologies—personalized medicine and organ transplant, mitochondrial DNA replacement, and scaffolds and (...) regenerative medicine—and their implications for our conceptualization of the human subject. Each is then followed by a commentary that both brings to light new dimensions of the original paper and presents a new theoretical take on the topic. Together these papers offer a serious challenge to the vision of the human subject at the root of human rights law. Instead of the autonomous, rational, unique, and physically discrete individual who owns herself and her body, the subject that emerges from the human technology assemblage has physically porous boundaries and a relational self. This depiction of the human being as a relational subject enmeshed in her technoscientific environment requires that we reconceptualize human rights law and practice. (shrink)

The ArgumentThis paper provides a historical perspective to one of the liveliest debates in common law courts today — the one over scientific expert testimony. Arguing against the current tendency to present the problem of expert testimony as a late twentieth-century predicament which threatens to spin out of control, the paper shows that the phenomena of conflicting scientific testimonies have been perennial for at least two centuries, and intensely debated in both the legal and the scientific communities for at least (...) 150 years.

Fertility treatments, which are part of "assisted reproductive technologies" (ART), mainly undertaken through in vitro fertilization (IVF), offer the opportunity to infertile couples to conceive. IVF treatments are undertaken in Israel in significantly higher numbers than in the rest of the world. As such, Israel provides an important case-in-point for examining the validity of the actual claims used to justify the more generous public funding of IVF treatments at the policy level. In this article, we utilize an analytical philosophy approach (...) to conduct this examination. First, we highlight two fundamental concepts that were used at the Israeli public policy level in order to justify the generous public funding of IVF treatments. These concepts are “emotional vulnerability” and the “worthlessness of the childless,” where the latter emphasizes the infinite value of children. Then, by applying the perspective of the European model of Bioethical Principlism, and focusing the attention to these two concepts we show that these justifications are invalid. Specifically, it is suggested that these concepts are on the one hand both relying on and expressing the principles of vulnerability, dignity, and integrity; yet on the other hand, these concepts are also undermining the very principles of bioethics they are supposed to express and rely on. Based on this suggested criticism, we offer two “take home” messages informed by our analysis of the Israeli case, but reaching beyond it. (shrink)

Early Buddhist Metaphysics provides a philosophical account of the major doctrinal shift in the history of early Theravada tradition in India: the transition from the earliest stratum of Buddhist thought to the systematic and allegedly scholastic philosophy of the Pali Abhidhamma movement. Entwining comparative philosophy and Buddhology, the author probes the Abhidhamma's metaphysical transition in terms of the Aristotelian tradition and vis-à-vis modern philosophy, exploits Western philosophical literature from Plato to contemporary texts in the fields of philosophy of mind and (...) cultural criticism.

Graham Priest has formulated the minimally inconsistent logic of paradox (MiLP), which is paraconsistent like Priest’s logic of paradox (LP), while staying closer to classical logic. We present logics that stand to (the propositional fragments of) strong Kleene logic (K3) and the logic of first-degree entailment (FDE) as MiLP stands to LP. That is, our logics share the paracomplete and the paraconsistent-cum-paracomplete nature of K3 and FDE, respectively, while keeping these features to a minimum in order to stay closer to (...) classical logic. We give semantic and sequent-calculus formulations of these logics, and we highlight some reasons why these logics may be interesting in their own right. (shrink)

The use of models to assign truth values to sentences and to counterexemplify invalid inferences is a basic feature of model theory. Yet sentences and inferences are not the only phenomena that model theory has to take care of. In particular, the development of sequent calculi raises the question of how metainferences are to be accounted for from a model-theoretic perspective. Unfortunately there is no agreement on this matter. Rather, one can find in the literature two competing model-theoretic notions of (...) metainferential validity, known as the ‘global’ notion and the ‘local’ notion. In this article, I argue that, given certain plausible considerations about metainferential validity, the global notion collapses into the local notion. (shrink)

The increasing awareness of personal health responsibility had led to the claim that patients with ‘self-inflicted’ conditions have less of a right to treatment at the public's expense than patients whose conditions arose from ‘uncontrollable’ causes. This paper suggests that regardless of any social decision as to the limits and scope of individual responsibility for health, the moral framework for discussing this issue is equality. In order to reach a consensus, discourse should be according to the common basis of all (...) theories of justice, Aristotle's formal principle of justice: ‘equals must be treated equally and unequals must be treated unequally, in proportion to the relevant inequality’. This paper deals with the question of whether and under what circumstances risk-taking behaviour could be regarded as a ‘relevant inequality’ with respect to the right to health care. Following a discussion of the relevant inequalities in health care, the conclusion is reached that the fact that the condition was avoidably caused by the patient and is therefore his or her fault can not be regarded necessarily as a relevant inequality. Therefore, the issue is one of societal support for health care; after defining relevant inequalities in this respect, the paper attempts to apply them to self-inflicted conditions. This analysis reveals that, in theory, it may be just to restrict societal support in such cases. However, the application of this conclusion requires proof of many factual claims—for which there is often very limited evidence. (shrink)

Conventionalism about logic is the view that logical principles hold in virtue of some linguistic conventions. According to explicit conventionalism, these conventions have to be stipulated explicitly. Explicit conventionalism is subject to a famous criticism by Quine, who accused it of leading to an infinite regress. In response to the criticism, several authors have suggested reconstructing conventionalism as implicit in our linguistic behaviour. In this paper, drawing on a distinction from proof theory between derivable and admissible rules, I argue that (...) implicit conventionalism has not been stated in a sufficiently precise way, as it leaves open what one needs to say about admissible yet underivable rules. Moreover, it turns out that this challenge cannot be easily met, and that any attempt to meet the challenge makes conventionalism much less attractive a thesis. (shrink)

I introduce a novel and quite intuitive interpretation of the ternary relation that figures in the relational semantics of many relevance logics. Conceptually, my interpretation makes use only of incompatibility and parthood relations, defined over a set of states. In this way, the proposed interpretation—of the ternary relation and the conditional—extends Dunn’s and Restall’s works on negation and the Routley star operator. Therefore, the interpretation is unified, and hence not only intuitive but also parsimonious. Additionally, the interpretation provides us with (...) a cogent argument to the effect that a ternary relation is indispensable, and we cannot merely do with a binary relation. (shrink)

Substructural solutions to the semantic paradoxes have been broadly discussed in recent years. In particular, according to the non-transitive solution, we have to give up the metarule of Cut, whose role is to guarantee that the consequence relation is transitive. This concession—giving up a meta rule—allows us to maintain the entire consequence relation of classical logic. The non-transitive solution has been generalized in recent works into a hierarchy of logics where classicality is maintained at more and more metainferential levels. All (...) the logics in this hierarchy can accommodate a truth predicate, including the logic at the top of the hierarchy—known as CMω—which presumably maintains classicality at all levels. CMω has so far been accounted for exclusively in model-theoretic terms. Therefore, there remains an open question: how do we account for this logic in proof-theoretic terms? Can there be found a proof system that admits each and every classical principle—at all inferential levels—but nevertheless blocks the derivation of the liar? In the present paper, I solve this problem by providing such a proof system and establishing soundness and completeness results. Yet, I also argue that the outcome is philosophically unsatisfactory. In fact, I’m afraid that in light of my results this metainferential solution to the paradoxes can hardly be called a “solution,” let alone a good one. (shrink)

Ignorance, or the lack of knowledge, appears to be steadily spreading, despite the increasing availability of information. The notion of informed ignorance herein proposed to describe the widespread position of being exposed to an abundance of information yet lacking relevant knowledge, which is tied to the exponential growth in misinformation driven by technological developments and social media. Linked to many of societies’ most looming catastrophes, from political polarization to the climate crisis, practices related to knowledge and information are deemed some (...) of the most imminent and daunting modern threats, evidenced by the latest report of the World Economic Forum, which has named misinformation the most severe short-term global risk. This paper’s epistemic perspective links the properties of today’s information culture and the ways in which it interacts with individual capacities and limitations in current technological and socio-political contexts. Such a position is analyzed through the lens of epistemic principles as a contemporary epistemic phenotype that emerges from an environment of ill-adapted and excessive information inputs and leads to a distinctive type of social injustice that is primarily epistemic in nature. While equity and accessibility are widely discussed as important contributing factors to epistemic discrepancies, other overlooked but fundamental issues underlying epistemic injustices are considered, such as information manipulation, cognitive limitations, and epistemic degradation. To effectively face this elusive threat, we propose an inclusive viewpoint that harnesses knowledge from cognitive science, science and technology studies, and social epistemology to inform a unifying theory of its main impacts and driving forces. By adjusting a modern epistemic framework to the described phenomena, we intend to contextually outline its trajectory and possible means of containment based on a shared responsibility to maintain ethical epistemic standards. In a time of international unrest and mounting civil acts of violence, it is pertinent to emphasize the ethical principles of knowledge systems and authorities and suggest policy adaptations to maintain a social contract based on the shared values of truth and freedom.

There is a pervasive view that inference—as opposed, notably, to a grasp of objects—is an intralinguistic process that does not draw on extralinguistic resources. The present paper aims to show that this dichotomy between inferring and grasping objects can be resisted. Specifically, I offer an alternative view: a phenomenological account according to which our most basic inferences draw on our grasp of objects. I motivate this account on the grounds that, although it is restricted to such basic inferences, it has (...) significant implications for the general question of whether inference involves taking one's premises to support one's conclusion. The proposed account implies that basic inferences need not involve corresponding “takings,” (even though such inferences involve conceptual content), but it leaves open the possibility that non-basic inferences do involve corresponding “takings,” while relying on basic inferences. It will turn out that such a disjunctive view, according to which non-basic reasoning is somewhat parasitic on basic reasoning, manages to avoid many of the problems with which the literature on the “taking condition” deals.

An ideal vision model accounts for behavior and neurophysiology in both naturalistic conditions and designed lab experiments. Unlike psychological theories, artificial neural networks (ANNs) actually perform visual tasks and generate testable predictions for arbitrary inputs. These advantages enable ANNs to engage the entire spectrum of the evidence. Failures of particular models drive progress in a vibrant ANN research program of human vision.

Models of set theory are constructed where the non-stationary ideal on PΩ1λ is presaturated. The initial model has a Woodin cardinal. Using the Lévy collapse the Woodin cardinal becomes λ+ in the final model. These models provide new information about the consistency strength of a presaturated ideal onPΩ1λ for λ greater than Ω1.

Nearly 30 years have passed since Donald Davidson first presented his ar- gument against the possibility of psychophysical laws in “Mental Events”. The argument applies to intentional rather than phenomenal properties, so whenever I refer to mental properties and to psychophysical laws it should be understood that I mean intentional properties and laws relating them to physical properties. No consensus has emerged over what the argument actually is, and the subsequent versions of it presented by Davidson show significant differences. But (...) many have been inclined to agree with the spirit of the argument and with its conclusion. (shrink)

Logical pluralists are committed to the idea of a neutral metalanguage, which serves as a framework for debates in logic. Two versions of this neutrality can be found in the literature: an agreed upon collection of inferences, and a metalanguage that is neutral as such. I discuss both versions and show that they are not immune to Quinean criticism, which builds on the notion of meaning. In particular, I show that the first version of neutrality is sub-optimal, and hard to (...) reconcile with the theories of meaning for logical constants, and the second version collapses mathematically, if rival logics, as object languages, are treated with charity in the metalanguage. I substantiate by proving a collapse theorem that generalizes familiar results. Thus, the existence of a neutral metalanguage cannot be taken for granted, and meaning-invariant logical pluralism might turn out to be dubious. (shrink)

This chapter focuses on the dispute between necessitarians and contingentists, mainly addressing the issue as to whether laws of nature are metaphysically necessary or metaphysically contingent with a weaker kind of necessity, commonly referred to as natural, nomological, or nomic necessity. It is assumed here that all fundamental properties are dispositional or role properties, making the dispute a strictly verbal one. The existence of categorical intrinsic properties as well as dispositional properties is also assumed and the relationship between them examined. (...) Finally, the chapter concludes by returning to the debate between necessitarians and contingentists under the assumption that both dispositional and categorical fundamental properties exist. It is argued here that necessitarian positions can be recast as contingentist, but that there are unequivocally contingentist positions preferred because they are less mysterious despite being ontologically more complex.

Plurality of beliefs and theories in different knowledge domains calls for modelling multi-viewpoint ontologies and knowledge organization systems. A generic theoretical approach recently proposed for heterogeneity representation in KOS was linking each ontological statement to a specific validity scope to determine a set of conditions under which the statement is valid. However, the practical applicability of this approach has yet to be empirically assessed. In addition, there is still a need to investigate the types of inconsistencies that might arise in (...) multi-viewpoint ontologies as well as their possible causes. This study proposes a new framework for systematic analysis and classification of inconsistencies in multi-viewpoint ontologies. The framework is based on eight generic logical structures of ontological statements. To test the validity of the proposed framework, two ontologies from different knowledge domains were examined. We found that only three of the eight structures led to inconsistencies in both ontologies, while the other two structures were always present in logically consistent statements. The study has practical implications for building diversified and personalized knowledge systems. (shrink)

ArgumentThis article describes how science and law were called upon (and failed) to resolve a controversy that created a painful rift between the Israeli State and some of its elite soldiers. The controversy, which came to be known as “the Kishon affair,” erupted in 2000, when veterans of an elite and secretive unit in the Israeli navy claimed that pollution in the Kishon River where they had trained and dived during their military service had been the cause of a rash (...) of cancers. The veterans demanded that the Ministry of Defense take responsibility for their illnesses, finance their medical treatment, and support their families if they die. The military denied the causal connection between the polluted river and the veterans’ cancers and rejected their demands. The dispute quickly escalated into a bitter public controversy, and a high-rank commission comprised of one of Israel's top jurists and two prominent scientists was called upon to study the disputed causal relation and reveal its true nature. However, after nearly three years of intense inquiry the jurist and the scientists reached opposing conclusions: the jurist found a causal connection while the scientists rejected it. (shrink)

Today we face the consequences of ‗God's death‘, or falling out of heaven, and with him the collapse of many ideologies and values. We witness the disintegration of the Other, the dissolution of prohibition, and the confusion and angst it creates. Also we witness a growing movement back to dogmatic religion and the emergence of persecuting fathers or small Gods: like the rise of totalitarianism of the laws of the market and rating, and the compulsion to enjoy. Is there another (...) alternative? Can psychoanalysis deal with these changes in new ways? This paper addresses these issues through clinical observations which show the tangent points of psychoanalysis, and spiritual and religious concepts. Examples include two cases of orthodox Jews, a man and a woman who obeyed the ceremonial aspects of religion to the letter; but there was no presence of god or spiritual experience whatsoever in their discourse. Therefore, they were struggling with broken identity, suffering and cynicism, and lost their defined place in the world. Two others: secular, atheistic man and woman discovered god and its representatives and found a new "name of the father". (shrink)

The current international asylum regime recognizes only persecuted persons as rightful asylum applicants. The Geneva Convention and Protocol enumerate specific grounds upon which persecution is recognized. Claimants who cannot demonstrate a real risk of persecution based on one of the recognized grounds are unlikely to be granted asylum. This paper aims to relate real-world practices to normative theories, asking whether the Convention’s restricted preference towards persecuted persons is normatively justified. I intend to show that the justifications of the persecution criterion (...) also apply to grounds currently lacking recognition. My main concern will be persecution on the grounds of gender.The first section introduces the dominant standpoints in theories of asylum, which give different answers to the question of who should be granted asylum, based on different normative considerations. Humanitarian theories base their claims on the factual neediness of asylum-seekers, holding that whoever is in grave danger of harm or deprivation should be granted asylum. Political theories base their justifications on conceptions of legitimacy and membership, holding that whoever has been denied membership in their original state should be granted asylum. Under political theories, Matthew Price’s theory will be discussed, which provides a normative justification of the currently recognized persecution criterion. The second section provides a descriptive definition of persecution based on Kuosmanen, and evaluates the normative relevance of the different elements of this definition based on the theories presented previously. The third section is devoted to the examination of the normative justifiability of the nexus clause’s exclusive list of the bases upon which persons might be persecuted. The section argues that while the clause does not recognize that persecution might be based on gender, in fact many women experience harms based on gender that fulfil all the normatively relevant definitive conditions constituting persecution. The conclusion shows that although the current law’s preferences towards the persecuted are justifiable, the nexus clause’s limiting enumeration of grounds is not. This applies especially to the exclusion of gender as grounds for granting asylum.Article first published online: 21 DEC 2015. (shrink)

The following is an account of an early Socialist approach to American historiography, including a biographical note on Fedor Kapelusz (1876–1945).

In contrast to the fruitful relationship between psychoanalysis/psychoanalysts and the humanities, institutionalized psychoanalysis has been largely resistant to the integration of psychoanalysis with other empirical branches of knowledge, as well as clinical ones [primarily cognitive-behavioral therapy ]. Drawing from two decades of theoretical and empirical work on psychopathology, psychotherapy, and psychoanalysis, the author aims to show how a reformulation of object relations theory using psychological science may enhance a clinical-psychoanalytic understanding and treatment of suicidal depression, which constitutes one of the (...) most formidable health challenges of our time. Specifically, he rewrote the notion of Melanie Klein positions—primarily the depressive position—using extant knowledge of structure of emotions, the centrality of mental representations of the future and the toxic nature of criticism-based emotions. This reformulation enables a dialog between clinical psychoanalysis and other therapeutic schools of thought and sheds light on the understanding and treatment of suicidal depression. (shrink)

Like many other staple metaphysical concepts, “determination” acquires its own special flavor when translated into the Spinozistic framework. This process is even more pronounced when applied to finite modes. This chapter explains what the necessary conditions are for finite modes to be determined, and furthermore in what this determination consists. It looks at a couple of key texts where Spinoza discusses determination and highlight what might initially seem puzzling. One consequence of adhering to a plenum physics for both Spinoza and (...) Descartes is that all motion is relative, and consequently, the proportion of motion and rest of a given body involves the proportion of motion and rest of surrounding bodies. The chapter concludes by highlighting the connection between determination and activity and the metaphysical consequences of this connection. (shrink)

This book offers a new way of approaching the place of the will in Descartes' mature epistemology and ethics. Departing from the widely accepted view, Noa Naaman-Zauderer suggests that Descartes regards the will, rather than the intellect, as the most significant mark of human rationality, both intellectual and practical. Through a close reading of Cartesian texts from the Meditations onward, she brings to light a deontological and non-consequentialist dimension of Descartes' later thinking, which credits the proper use of free will (...) with a constitutive, evaluative role. She shows that the right use of free will, to which Descartes assigns obligatory force, constitutes for him an end in its own right rather than merely a means for attaining any other end, however valuable. Her important study has significant implications for the unity of Descartes' thinking, and for the issue of responsibility, inviting scholars to reassess Descartes' philosophical legacy. (shrink)

This article explores attempts at legalization of the practice of euthanasia and assisted suicide. Although in many countries there have been high levels of public support for euthanasia and assisted suicide, in most of them, no legislative activity has taken place concerning these practices, and there is a lack of clarity about what is permitted and what is not. I argue that accurate definition of the relevant concepts and a clear delineation of the territory of the debate would help draw (...) a coherent roadmap for legalization. To this end, I analyze five legal approaches to the legalization euthanasia: maintenance of the status quo, legal defenses, de-prioritization, de-criminalization, and legislation. I conclude with a discussion of the moral and legal implications of the foregoing analysis. (shrink)

There is a long tradition of reading Spinoza as committed, perhaps unwillingly, to the non-reality of finite modes. While acknowledging that Spinoza does seem to rely on the reality of modes in certain places, Michael Della Rocca has called attention to what he labels an “idealist strand.” As a concluding remark in “Steps Toward Eleaticism in Spinoza's Philosophy of Action,” he claims that faced with these two conflicting strands, which are genuinely to be found in the text, it is better (...) to note both rather than artificially imposing a unity on the text. In this paper, I suggest that one need not admit two conflicting strands in Spinoza, on the one hand, nor arbitrarily disregard one strand, on the other. Rather, I argue for a unified view that diagnoses what gives rise to both seemingly conflicting strands. The key to this enterprise is recognizing that finite modes, paradoxically seeming perhaps at first, are not wholly finite. That is, a finite mode is determined by the totality of finite modes—wherein lies its finite aspect, but at the same time, and equally, partially actively determines this totality—wherein lies its infinite aspect.

Several authors maintain that we are capable of having inconsistent intentional states, either in cases of illusion, in certain cases of imagination, or because the observable world is (partly) inconsistent and we perceive it as such. These views are all premised on the assumption that inconsistent intentional states—even if acknowledged—are peculiar and have nothing essential to do with our perceptual capacities. In the present article, I would like to present, and argue for, a much stronger thesis: that inconsistent intentional states (...) underlie the possibility of having intentional content in mind. I argue for this thesis based on a Husserlian phenomenological analysis of our grasp of objects, which I formulate in terms of incompatibility semantics. (shrink)

Depression is associated with increased maintenance of negative affect (NA) and reduced – blunted and short-lived – maintenance of positive affect (PA). Studies have focused on factors associated with the maintenance of NA, specifically, the emotion regulation strategy of brooding and the capacity to hold negative affective experiences in working memory (WM). Despite its theoretical importance, less attention has been given to factors associated with the maintenance of PA in depression. This study aims to synthesise factors playing a role in (...) the maintenance of both NA and PA. Specifically, we used self-reported assessment of PA and NA regulation and performance-based measures of NA and PA processing in WM to predict depressive symptoms severity. Participants (N = 219) completed the Affective Maintenance Task (AMT, Mikels et al., Citation2008), which provided performance-based measures of PA and NA maintenance, and filled out questionnaires assessing brooding, positive rumination and depressive severity. Brooding, positive rumination and AMT-based measures of positive (but not negative) affective information processing were independently associated with depressive symptoms. We highlight the unique contributions of PA processing, as well as of self-reported emotion regulation strategies in understanding depression maintenance. (shrink)
