This book is an important study in the philosophy of the mind; drawing on the work of philosopher Wilfrid Sellars and the theory of critical realism to develop a novel argument for understanding perception and metaphysics.

The nature of perception has long been a central question in philosophy. It is of crucial importance not just in the philosophy of mind, but also in epistemology, metaphysics, aesthetics, and the philosophy of science. The essays in this 1992 volume not only offer fresh answers to some of the traditional problems of perception, but also examine the subject in light of contemporary research on mental content. A substantial introduction locates the essays within the recent history of the (...) subject, and demonstrates the links between them. The Contents of Experience brings together some prominent philosophers in the field, and offers a major statement on a problem central to current philosophical thinking. Notable contributors include Christopher Peacocke, Brian O'Shaughnessy and Michael Tye. (shrink)

Artificial intelligence is not only disrupting industries and businesses, particularly the ones have fallen behind the adoption, but also significantly impacting public life as well. This calls for government authorities pay attention to public opinions and sentiments towards AI. Nonetheless, there is limited knowledge on what the drivers behind the public perception of AI are. Bridging this gap is the rationale of this paper. As the methodological approach, the study conducts an online public perception survey with the residents (...) of Sydney, Melbourne, and Brisbane, and explores the collected survey data through statistical analysis. The analysis reveals that: the public is concerned of AI invading their privacy, but not much concerned of AI becoming more intelligent than humans; the public trusts AI in their lifestyle, but the trust is lower for companies and government deploying AI; the public appreciates the benefits of AI in urban services and disaster management; depending on the local context, public perceptions vary; and the drivers behind the public perception include gender, age, AI knowledge, and AI experience. The findings inform authorities in developing policies to minimise public concerns and maximise AI awareness. (shrink)

Recent research in cognitive and computational neuroscience portrays the neocortex as a hierarchically structured prediction machine. Several theorists have drawn on this research to challenge the traditional distinction between perception and cognition – specifically, to challenge the very idea that perception and cognition constitute useful kinds from the perspective of cognitive neuroscience. In place of this traditional taxonomy, such theorists advocate a unified inferential hierarchy subject to substantial bi-directional message passing. I outline the nature of this challenge and (...) then raise two objections to the cognitive architecture it proposes as a replacement: first, standard ways of characterising this inferential hierarchy are in tension with the representational reach of conceptual thought; second, there is compelling evidence that commonsense reasoning is structured around highly domain-specific intuitive theories that are difficult to situate within a single hierarchy.

The paper discusses the role affective factors may play in explaining why, in Capgras'delusion, the delusional belief once formed is maintained and argues that there is an important link between the modularity of the relevant emotional system and the persistence of the delusional belief.

The success of the Bayesian approach to perception suggests probabilistic perceptual representations. But if perceptual representation is probabilistic, why doesn't normal conscious perception reflect the full probability distributions that the probabilistic point of view endorses? For example, neurons in MT/V5 that respond to the direction of motion are broadly tuned: a patch of cortex that is tuned to vertical motion also responds to horizontal motion, but when we see vertical motion, foveally, in good conditions, it does not look (...) at all horizontal. This article argues that the best Bayesian approach to this problem does not require probabilistic representation. (shrink)

An extensive research program surrounding a phenomenon called inattentional blindness is reported by Mack and Rock in their book of the same name. The general conclusion that is drawn from the work is that no conscious perception can occur without attention. Because the bulk of the evidence surrounding inattentional blindness comes from memorial reports of displays, it is possible that inattentional blindness reflects a problem with memory, rather than a problem with perception. It is argued here that at (...) least some instances of inattentional blindness are better characterized as memorial failures than perceptual failures. The extent to which unattended stimuli fail to engage perceptual processing is an empirical question that the combination of inattentional blindness and online measures of processing can be used to address.

Platon düşünce tarihinde idealist felsefenin kuramlaştırıcısıdır. Sistematik bağlamda düşüncelerini diyaloglarla anlatmıştır. Diyaloglarda Yunan kültürünün yansımalarına, kültürün yaşam alanı bulduğu polislere de yer yer dikkat çekmiştir. Diyaloglarda bazen şehrin bir bölgesine, bazen bir halk kültürüne, bazen de herhangi bir yaşam olgusuna dikkat çekmektedir. Bu nedenle de onun eserlerinde polislerdeki yaşamın anlatısı tıpkı mitolojik ögeler ve analojiler gibi değerlendirilir ve diyalogdaki felsefi konunun anlaşılmasında kullanılır. Şehir yaşamından ögeler yer yer diyalog girişinde okuyucuyu konuya hazırlar, yer yer konunun ilerleyişinin gelişimini kavratmak için kullanılır. (...) Bu yönüyle Platon aynı zamanda bir kültür felsefecisidir. Amacımız diyaloglardaki Atina polisinin yansımalarını ortaya koymaktır. Diğer bir bağlamda Platon diyaloglarının şehir algısına bakışını siyaset felsefesi dışında kalarak kültürel bakışla ele alıp değerlendirmek olacaktır. Makale, diyaloglardan hareketle Platon’un diyaloglarında Atina polisinin yansımalarını, polisten hareketle de şehri ve kültürünü alt başlıklar halinde değerlendirmeye odaklanacaktır. Makale, şehir algısını (Atina) diyaloglardan hareketle yorumlamaya dayanan yöntemle ele almayı hedeflemektedir. (shrink)

Nichols offers the first comprehensive interpretation of the eighteenth-century Scottish philosopher Thomas Reid's theory of perception - by far the most important feature of his philosophical system. Nichols's consummate knowledge of Reid's texts, lively examples, and plainspoken style make this book especially readable. It will be the definitive analysis for a long time to come.

The perception theory of emotions mainly argues for the similarity between emotions and perception from different perspectives, including the argument for non-inferential structure, which proposes that emotions and perception share non-inferential structure and non-conceptual content; the argument from the epistemic role, which advocates for the similarity between emotions and perception from an epistemic perspective; and the argument from phenomenology, which argues for the similarity between emotions and perception from a phenomenal perspective. However, these arguments all (...) have some problems. In the argument for non-inferential structure, emotions not only follow the criterion of correctness but also the criterion of truth and are closer to beliefs, while perception only follows the criterion of correctness and is different from beliefs. The argument from the epistemic role overlooks the influence of individual differences on perception and emotions. The argument from phenomenology lacks reliable evidence for cognitively impenetrable emotions. (shrink)

The aim of the study was to determine the acceptance and perception of Nigerian patients to medical photography. A self-administered questionnaire was distributed among Nigerian patients attending oral and maxillofacial surgery and plastic surgery clinics of 3 tertiary health institutions. Information requested included patients' opinion about consent process, capturing equipment, distribution and accessibility of medical photographs. The use of non-identifiable medical photographs was more acceptable than identifiable to respondents for all purposes (P = 0.003). Most respondents were favourably disposed (...) to photographs being taken for inclusion in the case note, but opposed to identifiable photographs being used for other purposes most especially in medical websites and medical journals. Female respondents preferred non-identifiable medical photographs to identifiable ones (P = 0.001). Most respondents (78%) indicated that their consent be sought for each of the outline needs for medical photography. Half of the respondents indicated that identifiable photographs may have a negative effect on their persons; and the most commonly mentioned effects were social stigmatization, bad publicity and emotional/psychological effects. Most of the respondents preferred the use of hospital-owned camera to personal camera/personal camera-phone for their medical photographs. Most respondents (67.8%) indicated that they would like to be informed about the use of their photographs on every occasion, and 74% indicated that they would like to be informed of the specific journal in which their medical photographs are to be published. In conclusion, non-identifiable rather than identifiable medical photography is acceptable to most patients in the studied Nigerian environment. The use of personal camera/personal camera-phone should be discouraged as its acceptance by respondents is very low. Judicious use of medical photography is therefore advocated to avoid breach of principle of privacy and confidentiality in medical practice. (shrink)

Most philosophers agree that beliefs and perceptions represent the world to us and that a particular belief or perception is sometimes distinct from another particular belief or perception because what they represent is different; for example, one thing that distinguishes the belief that snow is white from the belief that grass is green is that the former represents snow while the latter represents grass. However, most philosophers of mind hold that a particular belief or perception is sometimes (...) distinct from another particular belief or perception because of how they represent. Indeed, though few philosophers explicitly recognize a distinction between what something represents and how it represents, the view that there is more to belief and perception than what they represent is about as close to philosophical orthodoxy as anything is. In this dissertation, I give a substantive account the relevant notion of representation and the distinction between what something represents and how it represents. I also bring out this hidden orthodoxy and argue that it is mistaken. Contrary to the orthodoxy, I defend the view that belief and perception present a single class of mental phenomena marked by their representational nature and that any mental difference between any two members of the class must be a difference in what they represent.

Perception of temporal patterns is fundamental to normal hearing, speech, motor control, and music. Certain types of pattern understanding are unique to humans, such as musical rhythm. Although human responses to musical rhythm are universal, there is much we do not understand about how rhythm is processed in the brain. Here, I consider findings from research into basic timing mechanisms and models through to the neuroscience of rhythm and meter. A network of neural areas, including motor regions, is regularly (...) implicated in basic timing as well as processing of musical rhythm. However, fractionating the specific roles of individual areas in this network has remained a challenge. Distinctions in activity patterns appear between "automatic" and "cognitively controlled" timing processes, but the perception of musical rhythm requires features of both automatic and controlled processes. In addition, many experimental manipulations rely on participants directing their attention toward or away from certain stimulus features, and measuring corresponding differences in neural activity. Many temporal features, however, are implicitly processed whether attended to or not, making it difficult to create controlled baseline conditions for experimental comparisons. The variety of stimuli, paradigms, and definitions can further complicate comparisons across domains or methodologies. Despite these challenges, the high level of interest and multitude of methodological approaches from different cognitive domains (including music, language, and motor learning) have yielded new insights and hold promise for future progress.
