There is a large tradition of work in moral psychology that explores the capacity for moral judgment by focusing on the basic capacity to distinguish moral violations (e.g. hitting another person) from conventional violations (e.g. playing with your food). However, only recently have there been attempts to characterize the cognitive mechanisms underlying moral judgment (e.g. Cognition 57 (1995) 1; Ethics 103 (1993) 337). Recent evidence indicates that affect plays a crucial role in mediating the capacity to draw the moral/conventional distinction. However, the prevailing account of the role of affect in moral judgment is problematic. This paper argues that the capacity to draw the moral/conventional distinction depends on both a body of information about which actions are prohibited (a Normative Theory) and an affective mechanism. This account leads to the prediction that other normative prohibitions that are connected to an affective mechanism might be treated as non-conventional. An experiment is presented that indicates that “disgust” violations (e.g. spitting at the table), are distinguished from conventional violations along the same dimensions as moral violations.

Introspection plays a crucial role in Modern philosophy in two different ways. From the beginnings of Modern philosophy, introspection has been used a tool for philosophical exploration in a variety of thought experiments. But Modern philosophers (e.g., Locke and Hume) also tried to characterize the nature of introspection as a psychological phenomenon. In contemporary philosophy, introspection is still frequently used in thought experiments. And in the analytic tradition, philosophers have tried to characterize conceptually necessary features of introspection.² But over the last several decades, philosophers have devoted relatively little attention to the cognitive characteristics of introspection. This has begun to change, impelled largely by a fascinating body of work on how children and autistic individuals understand the mind.³ In a pair of recent papers, Stephen Stich and I have drawn on this empirical work to develop an account of introspection or self-awareness.⁴ In this paper, I will elaborate and defend this cognitive theory of introspection further and argue that if the account is right, it may have important ramifications for psychological and philosophical debates over the self

Memory of past episodes provides a sense of personal identity — the sense that I am the same person as someone in the past. We present a neurological case study of a patient who has accurate memories of scenes from his past, but for whom the memories lack the sense of mineness. On the basis of this case study, we propose that the sense of identity derives from two components, one delivering the content of the memory and the other generating the sense of mineness. We argue that this new model of the sense of identity has implications for debates about quasi-memory. In addition, articulating the components of the sense of identity promises to bear on the extent to which this sense of identity provides evidence of personal identity.

Since the paper will cover a rather diverse set of issues, let me begin by mapping out the structure of what follows. In section II, I will set out the most prominent account of introspection in the recent literature, the Theory Theory of self-awareness, according to which.

Williams (1970) argues that our intuitions about personal identity vary depending on how a given thought experiment is framed. Some frames lead us to think that persistence of self requires persistence of one's psychological characteristics; other frames lead us to think that the self persists even after the loss of one's distinctive psychological characteristics. The current paper takes an empirical approach to these issues. We find that framing does affect whether or not people judge that persistence of psychological characteristics is required for persistence of self. Open-ended, abstract questions about what is required for survival tend to elicit responses that appeal to the importance of psychological characteristics. This emphasis on psychological characteristics is largely preserved even when participants are exposed to a concrete case that yields conflicting intuitions over whether memory must be preserved in order for a person to persist. Insofar as our philosophical theory of personal identity should be based on our intuitions, the results provide some support for the view that psychological characteristics really are critical for persistence of self.

Heal (1996a) maintains that evidence of cognitive penetrability doesn't determine whether stimulation theory or theory theory wins. Given the wide variety of mechanisms and processes that get called ‘simulation’, we argue that it's not useful to ask‘who wins?’. The label ‘simulation’picks out no natural or theoretically interesting category. We propose a more fine‐grained taxonomy and argue that some processes that have been labelled ‘simulation’, eg.,‘actual‐situation‐simulation’, clearly do exist, while other processes labelled ‘simulation’, e.g., ‘pretence‐driven‐off‐line‐simulation’are quite controversial. We do concede that evidence of cognitive penetrability isn't decisive evidence against pretence‐driven‐off‐line‐simulation. Nonetheless, advocates of pretence‐driven‐off‐line‐simulation need to provide some explanation of the experimental evidence of penetrability. We argue that Heal's suggestion that simulation is restricted to‘rational’processes is unprincipled, and we offer an alternative proposal for restricted simulation.

This volume presents new essays on the propositional imagination by leading researchers. The propositional imagination---the mental capacity we exploit when we imagine that everyone is colour-blind or that Hamlet is a procrastinator---plays an essential role in philosophical theorizing, engaging with fiction, and indeed in everyday life. Yet only recently has there been a systematic attempt to give a cognitive account of the propositional imagination. These thirteen essays, specially written for the volume, capitalize on this recent work, extending the theoretical picture of the imagination and exploring the philosophical implications of cognitive accounts of the imagination. The book also investigates broader philosophical issues surrounding the propositional imagination. The first section addresses the nature of the imagination, its role in emotion production, and its sophistication manifestation in childhood. The essays in the second section focus on the nature of pretence and how pretence is implicated in adult communication. The third section addresses the problem of 'imaginative resistance', the striking fact that when we encounter morally repugnant assertions in fiction, we seem to resist imagining them and accepting them as fictionally true. In the final section, contributors explore the relation between imagining, conceiving, and judgements of possibility and impossibility. The Architecture of the Imagination will be an essential resource for the growing number of philosophers and psychologists studying the nature of the imagination and on its role in philosophy, aesthetics, and everyday life

The everyday capacity to understand the mind, fancifully dubbed 'mindreading', plays an enormous role in our lives. In the latter half of the 20th century mindreading became the object of sustained scientific and theoretical research, capturing the attention of a wide range of disciplines, including philosophy, developmental psychology, behavioral ecology, anthropology, and cognitive psychopathology. What has been missing is a detailed and integrated account of the mental components that underlie this remarkable capacity. Nichols and Stich develop and defend a new account of the psychological mechanisms underlying mindreading. They maintain that it is, as common sense would suggest, vital to distinguish between reading others' minds and reading one's own. In reading other minds, the imagination plays a central role. As a result, the authors begin with an explicit and systematic account of pretence and imagination which proposes that pretence representations are contained in a separate mental workspace, the 'Possible World Box', which is part of the basic architecture of the human mind. The mechanisms underlying pretence get recruited when people attempt to understand others and predict their behaviour. In some cases, we use our own mental mechanisms to simulate the mental processes of another, as suggested by the 'simulation theory' of mindreading. However, mindreading also implicates very different kinds of mechanisms that rely on rich bodies of information, as suggested by information-based accounts of mindreading. In addition, the authors argue, reading other minds involves important processes that don't fit into either category. None of these mechanisms, though, explain how we read our own minds, which, according to the authors, requires invoking an entirely independent set of mechanisms.What we find, then, is an intricate web of mental components to explain our fascinating and multifarious knack of understanding minds. This account provides a valuable framework for future work on mindreading and has broad implications for philosophical debates that have surrounded the issue for the last quarter century.

Kühberger et al. show that producing the Langer effect is considerably more difficult than has been assumed. Although their results clearly demonstrate a need for further exploration of the Langer effect, none of their arguments undermines the evidence against simulation theory that we presented in Nichols et al. (1996). In our study the actor subjects did show an effect, but the prediction subjects did not predict it, despite the fact that they were provided with all the details of the actor's situation. Further, we report additional evidence that corroborates our empirical case against simulation theory.

Iteration presents opposing puzzles for a theory of the imagination. The first puzzle, noted by David Lewis, is that when a person pretends to pretend, the iteration is often preserved. Let’s call this the puzzle of ‘pre- served iteration’. At the other pole, Gregory Currie has noted that very often when we pretend to pretend, the iteration does collapse. We might call this the puzzle of ‘collapsed iteration’. Somehow a theory of the imagination must be able to address these two puzzles. I argue that an empirically inspired cognitive theory of the imagination (Nichols & Stich 2000) can accommodate both puzzles.

Experimental philosophy is a new interdisciplinary field that uses methods normally associated with psychology to investigate questions normally associated with philosophy. The present review focuses on research in experimental philosophy on four central questions. First, why is it that people's moral judgments appear to influence their intuitions about seemingly nonmoral questions? Second, do people think that moral questions have objective answers, or do they see morality as fundamentally relative? Third, do people believe in free will, and do they see free will as compatible with determinism? Fourth, how do people determine whether an entity is conscious?

According to recent accounts of the imagination, mental mechanisms that can take input from both imagining and from believing will process imagination‐based inputs (pretense representations) and isomorphic beliefs in much the same way. That is, such a mechanism should produce similar outputs whether its input is the belief that p or the pretense representation that p. Unfortunately, there seem to be clear counterexamples to this hypothesis, for in many cases, imagining that p and believing that p have quite different psychological consequences. This paper sets out some central problem cases and argues that the cases might be accommodated by adverting to the role of desires concerning real and imaginary situations.

It is common in various quarters of philosophy to derive philosophically significant conclusions from theories of reference. In this paper, we argue that philosophers should give up on such 'arguments from reference.' Intuitions play a central role in establishing theories of reference, and recent cross-cultural work suggests that intuitions about reference vary across cultures and between individuals within a culture (Machery et al. 2004). We argue that accommodating this variation within a theory of reference undermines arguments from reference.
