According to rich views of consciousness (e.g., James, Searle), we have a constant, complex flow of experience (or 'phenomenology') in multiple modalities simultaneously. According to thin views (e.g., Dennett, Mack and Rock), conscious experience is limited to one or a few topics, regions, objects, or modalities at a time. Existing introspective and empirical arguments on this issue (including arguments from 'inattentional blindness') generally beg the question. Participants in the present experiment wore beepers during everyday activity. When a beep sounded, they (...) were to take note of the conscious experience, if any, they were having at the last undisturbed moment immediately prior to the beep. Some participants were asked to report any experience they could remember. Others were asked simply to report whether there was visual experience or not (and if so, what it was). Still others were asked about experience in the far right visual field, or tactile experience, or tactile experience in the left foot. A majority of participants in the full experience and the visual conditions reported visual experience in every single sample. Tactile and peripheral visual experience were reported less often. However, the proper interpretation of these results is uncertain. (shrink)

"Self-knowledge" is commonly used in philosophy to refer to knowledge of one's particular mental states, including one's beliefs, desires, and sensations. It is also sometimes used to refer to knowledge about a persisting self -- its ontological nature, identity conditions, or character traits. At least since Descartes, most philosophers have believed that self-knowledge is importantly different from knowledge of the world external to oneself, including others' thoughts. But there is little agreement about what precisely distinguishes self-knowledge from knowledge in other (...) realms. Partially because of this disagreement, philosophers have endorsed competing accounts of how we acquire self-knowledge. These accounts have important consequences for the scope of mental content, for mental ontology, and for personal identity. (shrink)

The paper defends the position that phenomenological interviews can provide a rich source of knowledge and that they are in no principled way less reliable or less valid than quantitative or experimental methods in general. It responds to several skeptic objections such as those raised against introspection, those targeting the unreliability of episodic memory, and those claiming that interviews cannot address the psychological, cognitive and biological correlates of experience. It argues that the skeptic must either heed the methodological and epistemological (...) justification of the phenomenological interview provided, or embrace a more fundamental skepticism, a “deep mistrust”, in which scientific discourse can have no recourse to conscious processes as explananda, with ensuing dire consequences for our conception of science.

To study conscious experience we must, to some extent, trust introspective reports; yet introspective reports often do not merit our trust. A century ago, E.B. Titchener advocated extensive introspective training as a means of resolving this difficulty. He describes many of his training techniques in his four-volume laboratory manual of 1901- 1905. This paper explores Titchener's laboratory manual with an eye to general questions about the prospects of introspective training for contemporary consciousness studies, with a focus on the following examples: (...) introspective knowledge of the combination tones that arise when a musical interval is played; the 'flight of colours' in the afterimage of a field of bright, broad- spectrum light; and the possibility of non-obvious visual illusions. Introspective training appears to have some merit, but also to involve significant hazards. (shrink)

Reflection on skeptical scenarios in the philosophy of perception, made vivid in the arguments from illusion and hallucination, have led to the formulation of theories of the metaphysical and epistemological nature of perceptual experience. In recent times, the locus of the debate concerning the nature of perceptual experience has been the dispute between disjunctivists and common-kind theorists. Disjunctivists have held that there are substantial dissimilarities (either metaphysical or epistemological or both) between veridical perceptual experiences occurring when one perceives and perceptual (...) experiences involved in hallucination. Common-kind theorists have denied this. In this paper, I examine the nature of introspection – a faculty that has often been compared and contrasted to perception. I reflect on cases where introspection goes wrong in ways analogous to that in which our perceptual faculties can go wrong and formulate, what I take to be, an attractive theory of introspection. The cases that I focus on in which things go wrong are the case of zombies and the case of subjects with Anton’s syndrome. (Anton’s syndrome is a condition in which people who are blind claim that they can see.) I suggest that, just as it is possible to be a disjunctivist about perception, it is possible to be a disjunctivist about introspection. I argue that this is a good view of one type of introspection, namely, introspection of states that have phenomenal character, such as perceptual experiences. It has a good account to give of the cases in which such introspection seems to go wrong and it yields a plausible metaphysical and epistemological view of the nature of introspection. However, while I favour a disjunctive view of introspection, I do not favour a disjunctive view of perception. And, I suspect, that many disjunctivists about perception would not wish to condone my disjunctivist theory of introspection. I therefore go on to examine to what extent.. (shrink)

This thesis is an empirical and theoretical exploration of the surprising finding that people often may fail to notice dramatic mismatches between what they want and what they get, a phenomenon my collaborators and I have named choice blindness. The thesis consists of four co-authored papers, dealing with different aspects of the phenomenon. Paper one presents an initial set of studies using a computerised choice procedure, and discusses the relation of choice blindness to the parent phenomenon of change blindness. Paper (...) two is the most central paper of the thesis. In this study, participants were shown pairs of pictures of female faces, and were instructed to choose which face in each pair they found most attractive. In addition, on some trials, immediately after their choice, they were asked to verbally describe the reasons for choosing the way they did. Unknown to the participants, on certain trials, a double-card ploy was used to covertly exchange one face for the other. On these trials, the outcome of the choice became the opposite of what they intended. Counting across all conditions of the experiment no more than a fourth of all such manipulated trials were detected. But not only were the participants in the experiment blind to the manipulation of their choices, they also offered introspectively derived reasons for preferring the alternative they were given instead. A second major conclusion of this paper is that normal participants may produce confabulatory reports when asked to describe the reasons behind their choices. Paper three applies this form of analysis of introspection and confabulation to a second corpus of reports collected within the choice blindness paradigm. In this paper we use word-frequency and latent semantic analysis to contrast the introspective reasons given in non-manipulated and manipulated trials, but very few differences between these two groups of reports were found. In paper four, passer-by shoppers in a local supermarket were invited to sample two different varieties of jam and tea, and to decide which alternative in each pair they preferred the most. After their choice, the participants were asked to again sample to chosen alternative and describe why that one was preferred. At this point, the content of the sample containers were secretly switched, so that the outcome of the choice became the opposite of what the participants intended. No more than a third of the manipulated trials were detected, thus demonstrating considerable levels of choice blindness for the taste and smell of two different consumer goods. (shrink)

This paper argues for a position of ‘dark pessimism’ towards introspective reports playing a strong justificatory role in consciousness science, based on the application of frameworks and concepts of measurement. I first show that treating introspective reports as measurements fits well within current discussions of the reliability of introspection, and argue that introspective reports must satisfy at least a minimal definition of measurement in order to play a justificatory role in consciousness science. I then show how treating introspective reports as (...) measurements makes it possible to identify the foundational methodological problems that underlie much of the current philosophical and scientific debate about the status of introspective evidence in studying consciousness. I argue that these problems prevent introspective reports from playing a strong justificatory role and resolving long-standing debates in consciousness science, both in contemporary work and in the future.

Patient or public involvement in health research is increasingly expected as a matter of policy. In theory, PPI can contribute both to the epistemic aims intrinsic to research, and to extrinsically valued features of research such as social inclusion and transparency. In practice, the aims of PPI have not always been clear, although there has been a tendency to encourage the involvement of so-called ordinary people who are regarded as representative of an assumed patient perspective. In this paper we focus (...) on the epistemic potential of PPI, using theoretical work in epistemology to develop a nuanced account of patients’ experiential knowledge and how this might contribute directly to conceptual development, hypothesis generation and data interpretation. We also consider how some features of health research pose barriers to this kind of epistemic contribution. Drawing on Miranda Fricker’s idea of testimonial injustice, we explore how disciplinary indicators of credibility in clinical and academic health research contexts might be wrongly applied to those involved in PPI, undermining their potential to contribute. Finally we argue for a range of strategies to maximize opportunities for patients to engage with research teams and make epistemologically significant contributions to research. (shrink)

Imagination is widely thought to come in two varieties: perception-like and belief-like imagination. What precisely sets them apart, however, is not settled. More needs to be said about the features that make one variety perception-like and the other belief-like. One common, although typically implicit, view is that they mimic their counterparts along the conceptuality dimension: while the content of belief-like imagination is fully conceptual, the content of perception-like imagination is fully non-conceptual. Such a view, however, is not sufficiently motivated in (...) the literature. I will show that there are good reasons to reject it and I will argue that both varieties of imagination involve fully conceptual contents. I will suggest an alternative way to draw the distinction between perception-like and belief-like imagination along the conceptuality dimension, according to which only perception-like imagination requires observational concepts.

In the 1950s, dream researchers commonly thought that dreams were predominantly a black and white phenomenon, although both earlier and later treatments of dreaming assume or assert that dreams have color. The first half of the twentieth century saw the rise of black and white film media, and it is likely that the emergence of the view that dreams are black and white was connected to this change in film technology. If our opinions about basic features of our dreams can (...) change with changes in technology, it seems to follow that our knowledge of the experience of dreaming is much less secure than we might at first have thought it to be.

What happens when a psychologist who’s spent the last 30 years developing a method of introspective sampling and a philosopher whose central research project is casting skeptical doubt on the accuracy of introspection write a book together? The result, Hurlburt & Schwitzgebel’s thought-provoking Describing Inner Experience?, is both encouraging and disheartening. Encouraging, because the book is a fine example of fruitful and open-minded interdisciplinary engagement; disheartening, because it makes clear just how difficult it is to justify the accuracy of introspective (...) methods in psychology and philosophy. And since debates in consciousness studies largely turn on fine points of introspective detail, this is no minor methodological stumbling block. (shrink)

Dennett argues that we can be mistaken about our own conscious experience. Despite this, he repeatedly asserts that we can or do have unchallengeable authority of some sort in our reports about that experience. This assertion takes three forms. First, Dennett compares our authority to the authority of an author over his fictional world. Unfortunately, that appears to involve denying that there are actual facts about experience that subjects may be truly or falsely reporting. Second, Dennett sometimes seems to say (...) that even though we may be mistaken about what our conscious experience is, our reports about “what it’s like to be us” must be correct. That view unfortunately requires a nonstandard and unremarked distinction between facts about consciousness and facts about “what it’s like.” Third, Dennett says that reports about experience may be “incorrigible.” However, that claim stands in tension with evidence, highlighted by Dennett himself, that seems to suggest that people can be demonstrably mistaken about their own experience. Dennett needlessly muddies his case against infallibilism with these unsatisfactory compromises. (shrink)

The paper proposes a minimal definition of dreaming in terms of immersive spatiotemporal hallucination (ISTH) occurring in sleep or during sleep–wake transitions and under the assumption of reportability. I take these conditions to be both necessary and sufficient for dreaming to arise. While empirical research results may, in the future, allow for an extension of the concept of dreaming beyond sleep and possibly even independently of reportability, ISTH is part of any possible extension of this definition and thus is a (...) constitutive condition of dreaming. I also argue that the proposed ISTH model of dreaming, in conjunction with considerations on the epistemic relationship between dreaming and dream reports, raises important questions about the extent to which dreams typically involve a detailed body representation—an assumption that plays an important role in philosophical work on dreaming. As a commonly accepted definition of dreaming is lacking in current dream research, the ISTH model, which integrates conceptual analysis and epistemological considerations with results from empirical research, is an important contribution to this field. By linking dreaming to felt presence, full-body illusions, and autoscopic phenomena such as out-of-body experiences in wakefulness and in the hypnagogic state, the ISTH model of dreaming also helps integrate dream research, both theoretically and experimentally, with the study of other altered states of consciousness involving hallucinations. It makes straightforward and investigable predictions by claiming that all of these experiences have amodal spatiotemporal hallucinations as their common denominator. Finally, it is theoretically relevant for the philosophical discussion on minimal phenomenal selfhood. (shrink)
