Implicit and explicit attitudes manifest themselves as distinct and partly dissociable behavioral dispositions. It is natural to think that these differences reflect differing underlying representations. The present article argues that this may be a mistake. Although non-verbal and verbal measures of attitudes often dissociate, this may be because the two types of outcome-measure are differentially impacted by other factors, not because they are tapping into distinct kinds of representation or distinct storage systems. I arrive at this view through closer consideration (...) than is usual of the mechanisms and processes that underlie overt behavior. (shrink)

In a pair of recent papers and his new book, Christopher Peacocke (2007, 2008a, 2008b) takes up and defends the claim that our awareness of our own actions is immediate and not perceptually based, and extends it into the domain of mental action.1 He aims to provide an account of action-awareness that will generalize to explain how we have immediate awareness of our own judgments, decisions, imaginings, and so forth. These claims form an important component in a much larger philosophical (...) edifice, with many implications for the philosophy of mind and for epistemology. The present paper advances multiple criticisms of Peacocke's account. In particular, it shows that he has given insufficient grounds for thinking that we have non-perceptual awareness of our own actions; and it shows that the account of action-awareness that he provides does not, in any case, generalize to mental actions of the sort that he intends.

Does the Wright & Liley model predict: (1) that subdural and hippocampal EEGs coherence tend to rise and fall in parallel for many frequencies, (2) that it is locally high or low within 10mm and falls steeply on average or, (3) that it is in constant flux, mostly rising and falling within 5–15 sec?

Preadaptation for language is an unnecessary assumption because intermediate stages of linguistic ability are possible and adaptive. Language could have evolved through gradual selection from structures exhibiting few features associated with modern structures. Without physical evidence pertaining to language ability in prehabilis hominids, it remains possible that selective pressures for language use preceded and necessitated modern neurolinguistic structures.

What does it mean to know oneself, and what is the self that one hopes to know? This article outlines the implications of an embodied understanding of persons and some aspects of the “self” that are generally ignored when thinking about our selves. The Cartesian model of body–soul dualism reinforces the idea that there is within us a soul, or self, or mind that is our hidden, inner, and real self. Thus, the path to self-knowledge is introspection. The alternative view (...) is that persons are embodied, embedded, and at times extended. This article emphasizes the bodily, active, contextual, relational, often simulated, and sometimes extended nature of the selves that we are, and that we hope to know. (shrink)

Why do irrational beliefs adopt the trappings of science, to become what is known as “pseudoscience”? Here, we develop and extend an epidemiological framework to map the factors that explain the form and the popularity of irrational beliefs in scientific garb. These factors include the exploitation of epistemic vigilance, the misunderstanding of the authority of science, the use of the honorific title of “science” as an explicit argument for belief, and the phenomenon of epistemic negligence. We conclude by integrating the (...) various factors in an epidemiological framework and thus provide a comprehensive cultural evolutionary account of science mimicry. (shrink)

Despite some sound basic assumptions, Wilkins & Wakefield portray a Homo habilis too linguistically sophisticated to fit in with the subsequent fossil record and thereby lose a reasoned explanation for human innovativeness. They err, too, in accepting a single-level model of conceptual structure and in deriving initial linguistic units from calls, a process far more dubious than the derivation of home-sign from naive gesture.

A crucial disanalogy between Twin Earth and Inverted Earth undermines qualia‐internalism. A recent transplant to Inverted Earth has been equipped with color‐inverting contact lenses, so that she is unable to see the colors of objects whereas a recent transplant to Twin Earth can see twater. It is implausible to think that time alone could rectify this perceptual shortcoming – that the passage of time could alter the contents of her visual perceptions or the meaning of her color terms. Thus, the (...) thought experiment does not refute the close tie between phenomenology and representation in the case of color. (shrink)

Although information-processing theories cannot provide a full explanatory account of P-consciousness, there is less conflation and confusion in cognitive psychology than Block suspects. Some of the reasoning that Block criticises can be interpreted plausibly in the light of a folk psychological view of the relation between P-consciousness and A-consciousness.

Block's distinction between phenomenal and access consciousness is accepted, and it is agreed that one may be found without the other, but his account of the distinction is challenged. Phenomenal consciousness is perceptual consciousness, and it is a matter of gaining information of a detailed, nonverbal sort about the subject's body and environment. Access consciousness is good, old-fashioned introspection.

While "Consciousness Explained" has received an enormous amount of attention since its publication, there is still little agreement on what Dennett’s account of consciousness is. Most interpreters treat his view as an instance of one or another of the standard ontological positions (functionalism, behaviorism, eliminativism, instrumentalism). I believe a different metaphysical account underlies Dennett’s view, one that is important though ill-understood. In the paper I attempt to point in the direction of a proper characterization of that account through the use (...) of two illustrative examples. A ten-point story that applies to the examples is developed, and it is suggested that the story applies equally well to Dennett’s view of consciousness. (shrink)

The paper discusses some recent suggestions offered by the so-called sensorimotor (or enactivist) theorists as to the problem of the explanatory gap, that is, the alleged impossibility of accounting for phenomenal consciousness in any scientific theory. We argue in the paper that, although some enactivist theorists’ suggestions appear fresh and eye-opening, the claim that the explanatory gap is (dis)solved is much overstated.

This paper offers practical advice about how to interact with machines that we have reason to believe could have minds. I argue that we should approach these interactions by assigning credences to judgements about whether the machines in question can think. We should treat the premises of philosophical arguments about whether these machines can think as offering evidence that may increase or reduce these credences. I describe two cases in which you should refrain from doing as your favored philosophical view (...) about thinking machines suggests. Even if you believe that machines are mindless, you should acknowledge that treating them as if they are mindless risks wronging them. Suppose your considered philosophical view that a machine has a mind leads you to consider dating it. You may have reason to regret that decision should these dates lead on to a life-long relationship with a mindless machine. In the paper’s final section, I suggest that building a machine that is capable of performing all intelligent human behavior should produce a general increase in confidence that machines can think. Any reasonable judge should count this feat as evidence in favor of machines having minds. This rational nudge could lead to broad acceptance of the idea that machines can think. (shrink)

This paper is both systematic and historical in nature. From a historical viewpoint, I aim to show that to establish Wittgenstein’s claim that “an ‘inner process’ stands in need of outward criteria” there is an enthymeme in Wittgenstein’s private language argument overlooked in the literature, namely Wittgenstein’s suggestion that both perceptual and bodily experiences are _transparent_ in the relevant sense that one cannot point to a mental state and wonder “What is that?” From a systematic viewpoint, I aim to show (...) that Wittgenstein’s PLA teaches us that the prevailing picture of the nature of phenomenal concepts is upside down: we can only introspectively know what is going on inside our heads, after we learn of what is going on outside. In this regard, I aim to defend two associate claims against the prevailing view of PCs on the basis of PLA. First, by means of transparency, I aim to show that there is no _de re_ awareness of our private sensation that could determine the meaning of sensation-words; for example, I am never aware _of _the phenomenal blueness of my experience of something blue. The second associated claim is that introspective self-knowledge of our private sensation is always _de dicto_. We can only know introspectively that phenomenal blueness is the phenomenal character of the experience we are undergoing after we have learned _that _ blue is the color that usually causes in us that kind of experience. Likewise, we can only introspectively know that pain is the phenomenal character of the experience we are undergoing after we have learned that pain is what usually causes some typical pain behavior.

The perpetual music track is a new concept that describes a condition of constant or near-constant musical imagery. This condition appears to be very rare even among composers and musicians. I present here a detailed self-analysis of musical imagery for the purpose of defining the psychological features of a perpetual music track. I have music running through my head almost constantly during waking hours, consisting of a combination of recently- heard pieces and distant pieces that spontaneously pop into the head. (...) Imagery consists mainly of short musical fragments that get looped repeatedly upon themselves. Corporeal manifestations of imagery occur in the form of unconscious finger movements whose patterns correspond to the melodic contour of the imagined piece. Musical dreams occur every week or two, and contain a combination of familiar and originally- composed music. These results are discussed in light of theories of imagery, consciousness, hallucination, obsessive cognition, and most especially the notion that acoustic consciousness can be split into multiple parallel streams.

The mind body problem is a continuing issue in philosophy. No surveys known to us have been conducted about the actual preferences of, for example, psychology students for particular preconceptions about the mind body relation. These preconceptions may have different practical implications for decisions concerning the object and method of research, the choice of explanatory device for psychological and other research data and for the approach of professionals in practice. A questionnaire comprising ten different preconceptions about the mind body relation (...) and other items was returned by 209 German students of various disciplines and by a second sample of 233 first year psychology students. Identity theory, interactionism and complementarity were preferred most. The students clearly believed that the preference for certain preconceptions has important practical implications. There were no differences between the students of different disciplines in the choice of preferred preconceptions about the mind body relation or in the view that these preconceptions are of practical importance.

David Haig propounds and illustrates the unity of a radically revised set of definitions of the family of terms at the heart of philosophy of cognitive science and mind: information, meaning, interpretation, text, choice, possibility, cause. This biological re-grounding of much-debated concepts yields a bounty of insights into the nature of meaning and life. An interpreter is a mechanism that uses information in choice. The capabilities of the interpreter couple an entropy of inputs to an entropy of outputs is dispelled (...) by observation. The second entropy is dispelled. I propose that an interpreter’s response to inputs meaning of the information for the interpreter. In this conceptual framework, the mechanisms of interpreters provide the much-debated link between Shannon information and semantics. (shrink)

By characterizing the function of the ventral and dorsal visual streams as, respectively, vision-for-perception and vision-for-action, Milner and Goodale have brought some action onto the perceptual scene. However, with the distinction of the ventral "what" system and the dorsal "how" system, comes a dilemma: How is the operation of the two systems united toward common goals? This is an example of a binding problem. We propose that for binding these two systems, no mechanism needs to exist in the brain to (...) bring ventral and dorsal representations together. Coherent behavior may be accomplished by focusing the two streams upon the same external object through a strategy of spatial selection, using either the fovea or selective attention. This strategy exploits the simple fact that two objects cannot occupy the same place at the same time. Other kinds of binding, like that involving the perceptual binding of the elements of a scene into coherent perceptual units, may be accomplished by exploiting other regularities of the environment, such as the likelihood that two simultaneous sounds were caused by a common event. From an evolutionary perspective, the most effective way to cope with the distant environment is to use different but complementary sensors, both contributing to aspects of identification and action guidance. For example, audition plays a role both in perceptual analysis and in action guidance, suggesting the possibility of segregated processing of auditory information. Thus, the functional distinction between a "what" system and a "how" system may not be limited to the visual modality, but may be a fundamental distinction for behavioral control in general.

While we agree that the frame problem, as initially stated by McCarthy and Hayes (1969), is a problem that arises because of the use of representations, we do not accept the anti-representationalist position that the way around the problem is to eliminate representations. We believe that internal representations of the external world are a necessary, perhaps even a defining feature, of higher cognition. We explore the notion of dynamically created context-dependent representations that emerge from a continual interaction between working memory, (...) external input, and long-term memory. We claim that only this kind of representation, necessary for higher cognitive abilities such as counterfactualization, will allow the combinatorial explosion inherent in the frame problem to be avoided.

Rapid advances in the field of neuroimaging techniques including magnetoencephalography (MEG), electroencephalography (EEG), functional MRI (fMRI), diffusion tensor imaging (DTI), voxel based morphomentry (VBM), and optical imaging, have allowed neuroscientists to investigate neural processes in ways that have not been possible until recently. Combining these techniques with advanced analysis procedures during different conditions such as hypnosis, psychiatric and neurological conditions, subliminal stimulation, and psychotropic drugs began transforming the study of neuroscience, ushering a new paradigm that may allow neuroscientists to tackle (...) the hard problem of consciousness.

This monograph explains in terms of specified neuronal brain mechanisms and systems, how the human brain does its cognitive work. It elucidates functions such as declarative and episodic learning, imagery, spatial representation, object recognition, semantic processing, narrative comprehension, planning, and motivation. Neurophysiological, psychological, and clinical findings are presented in support of the theoretical model, and a variety of computer simulation tests demonstrate its competence. -/- .

This paper is a response to some recent discussions of many-minds interpretations in the philosophical literature. After an introduction to the many-minds idea, the complexity of quantum states for macroscopic objects is stressed. Then it is proposed that a characterization of the physical structure of observers is a proper goal for physical theory. It is argued that an observer cannot be defined merely by the instantaneous structure of a brain, but that the history of the brain's functioning must also be (...) taken into account. Next the nature of probability in many-minds interpretations is discussed and it is suggested that only discrete probability models are needed. The paper concludes with brief comments on issues of actuality and identity over time. (shrink)

The distinction between phenomenal and access consciousness arises from the battle between biological and computational approaches to the mind. If P = A, the computationalists are right; but if not, the biological nature of P yields its scientific nature.

Our understanding of human visual perception generally rests on the assumption that conscious visual states represent the interaction of spatial structures in the environment and our nervous system. This assumption is questioned by circumstances where conscious visual states can be triggered by external stimulation which is not primarily spatially defined. This work discusses psychophysical experiments investigating flicker induced subjective experiences of colour and form. Using the presentation of spatially uniform flicker with a precise temporal resolution it is shown that subjective (...) experiences do not only depend on stimulation frequency, but also on stimulation phase. In addition, the occurrence of one subjective experience appears to be associated with the occurrence of others. The phenomenology of subjective colour and form is further explored and the physiological mechanisms underlying subjective colour are investigated using electroencephalography. While these data indicate that conscious visual experience may be evoked directly by particular variations in the flow of spatially unstructured light over time it may be assumed that the systems reponsible are essentially temporal in character and capable of representing a variety of visual forms and colours, coded in different frequencies or at different phases of the same processing rhythm.

In this paper we aim to defend a version of the thesis of “extended mind” against the criticism of some authors that consider that the “extracraneal” devices cannott acomplish the requirements that the components of mental processes must meet. We propose a quality of integration as a criterion to be a mental process, and we consider that, in some situations, external devices can be considered as meeting this criterion.
