In this article we examine obsessive compulsive disorder (OCD). We examine and reject two existing models of this disorder: the Dysfunctional Belief Model and the Inference‐Based Approach. Instead, we propose that the main distinctive characteristic of OCD is a hyperactive sub‐personal signal of being in error, experienced by the individual as uncertainty about his or her intentional actions (including mental actions). This signalling interacts with the anxiety sensitivities of the individual to trigger conscious checking processes, including speculations about possible harms. (...) We examine the implications of this model for the individual's capacity to control his or her thoughts. (shrink)

A familiar feature of moral life is the distinctive anxiety that we feel in the face of a moral dilemma or moral conflict. Situations like these require us to take stands on controversial issues. But because we are unsure that we will make the correct decision, anxiety ensues. Despite the pervasiveness of this phenomenon, surprisingly little work has been done either to characterize this “ moral anxiety” or to explain the role that it plays in our moral lives. This paper (...) aims to address this deficiency by developing an empirically informed account of what moral anxiety is and what it does. (shrink)

Reprinted in Philosophy of Religion: An Anthology, Wadsworth 2015, 6th edition, eds Michael Rea and Louis Pojman. What is propositional faith? At a first approximation, we might answer that it is the psychological attitude picked out by standard uses of the English locution “S has faith that p,” where p takes declarative sentences as instances, as in “He has faith that they’ll win”. Although correct, this answer is not nearly as informative as we might like. Many people say that there (...) is a more informative answer. They say that, at the very least, propositional faith requires propositional belief. More precisely, they say that faith that p requires belief that p or that it must be partly constituted by belief that p. This view is common enough; call it the Common View. I have two main aims in this paper: (i) to exhibit the falsity of the Common View and the paucity of reasons for it, and (ii) to sketch a more accurate and comprehensive account of what propositional faith is.

This paper explores the nature of curiosity from an epistemological point of view. First it motivates this exploration by explaining why epistemologists do and should care about what curiosity is. Then it surveys the relevant literature and develops a particular approach.

Do we apply higher epistemic standards to subjects with high stakes? This paper argues that we expect different outward behavior from high-stakes subjects—for example, we expect them to collect more evidence than their low-stakes counterparts—but not because of any change in epistemic standards. Rather, we naturally expect subjects in any condition to think in a roughly adaptive manner, balancing the expected costs of additional evidence collection against the expected value of gains in accuracy. The paper reviews a body of empirical (...) work on the automatic regulation of cognitive effort in response to stakes, and argues that we naturally see high- and low-stakes subjects as experiencing different levels of ‘epistemic anxiety’, and anticipate different levels of cognitive effort from them for this reason. If unresolved epistemic anxiety always bars an ascription of knowledge, then we can explain our responses to cases involving shifting stakes without positing any variation in the standards of intuitive knowledge ascription.

David Lewis (1941-2001) was Class of 1943 University Professor of Philosophy at Princeton University. His contributions spanned philosophical logic, philosophy of language, philosophy of mind, philosophy of science, metaphysics, and epistemology. In On the Plurality of Worlds, he defended his challenging metaphysical position, "modal realism." He was also the author of the books Convention, Counterfactuals, Parts of Classes, and several volumes of collected papers.

This paper proposes an integrated account of the etiology of OCD that accommodates both dysfunctional cognitions and sensorimotor features of compulsive action. It is argued that cognitive/metacognitive theories do not aspire to address all obsessive-compulsive phenomenal properties and that empirical evidence concerning some of these requires the incorporation of motor deficits as an independent factor in a plausible conception of OCD. The difference in agency attribution between obsessive-compulsive persons and schizophrenia patients with delusions of control is also accounted for in (...) terms of bottom-up processes. (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)

Research on self-agency emphasizes the importance of a comparing mechanism, which scans for a match between anticipated and actual outcomes, in the subjective experience of doing.This study explored the “feeling of doing” in individuals with checking symptoms by examining the mechanism involved in the experienced agency for outcomes that matched expectations. This mechanism was explored using a task in which the subliminal priming of potential action-effects generally enhances people’s feeling of causing these effects when they occur, due to the unconscious (...) perception of a match between primed and observed outcomes. The main result revealed a negative relationship between checking and self-agency for observed outcomes that were primed prior to actions. This suggests that checking individuals fail to grasp the correspondence between actual outcomes of their actions and expected ones. We discuss the possible role of undermined self-agency in checking phenomena and its relationship with cognitive dysfunction. (shrink)

Despite the prominence of doubt in philosophy since Descartes, the published philosophical literature includes no extended treatment of the nature of doubt. In this paper, I summarize the main contributions that have been made to the subject and then develop a commonsense functionalist account of doubt by specifying the functional role of doubt that something is the case. After adding two further wrinkles, I show how the resulting account can be used to address the questions of how doubt is related (...) to belief and whether suspension of judgment can be identified with doubt. Although the account is partisan, it should hold interest for those who favor other positions in the philosophy of mind, since much of the account can be taken on board by those in other camps, and the paper demonstrates how a sufficiently detailed account of doubt can be put to work addressing longstanding questions of interest across philosophical sub-disciplines.

Explicit measures of human memory, such as recall or recognition, reflect conscious recollection of the past. Implicit tests of retention measure transfer (or priming) from past experience on tasks that do not require conscious recollection of recent experiences for their performance. The article reviews research on the relation between explicit and implicit memory. The evidence points to substantial differences between standard explicit and implicit tests, because many variables create dissociations between these tests. For example, although pictures are remembered better than (...) words on explicit tests, words produce more priming than do pictures on several implicit tests. These dissociations may implicate different memory systems that subserve distinct memorial functions, but the present argument is that many dissociations can be understood by appealing to general principles that apply to both explicit and implicit tests. Phenomena studied under the rubric of implicit memory may have important implications in many other fields, including social cognition, problem solving, and cognitive development.
