Alexander of Aphrodisias picks up Aristotle’s insufficient treatment of simultaneous perception and develops an adequate solution for the problem, thereby offering an account of the unity of perceptual consciousness—the single mental activity of a single subject with complex content. I show the adequacy of the solution by using as criteria the requirements that have been identified by Aristotle and approved (and explained) by Alexander. I analyze Alexander’s solution in two turns. First, with respect to heterogeneous perceptibles, Alexander adopts (...) and reformulates Aristotle’s metaphorical account invoking the analogy with a point. Second, with respect to homogeneous opposites, accordingly, perception is judgement, but it involves physical changes in diverse parts of the primary sense-organ. By this account Alexander resolves the issue of the unity of the subject on the level of the capacity of the soul, and coordinates the complexity of content with the complexity on the physical level. In addition to being adequate, the solution is faithful to Aristotle. I suggest that the interpretative decisions Alexander makes (the clarification of the analogy; the reference he finds to the analogy; the two components of the solution, judgement and parts of the organ) form an ingenious extension of Aristotle’s treatment. Interestingly, even though many elements in Alexander’s interpretation are taken up by modern commentators, no one has followed it in its entirety, nor even treated it in its own right. (shrink)

This article consists of critical editions of a selection of medieval commentaries on the chapter seven of Aristotle’s De sensu et sensato, which pertains to a particular philosophical problem, namely, the possibility of perceiving many perceptual qualities simultaneously. The commentaries included are written by Adam of Buckfield, Anonymous of Merton, Radulphus Brito, Anonymous of Paris, John Felmingham(?), Walter Burley, John of Jandun, and John Buridan. The most significant discovery made in the course of preparing the editions concerns Walter Burley’s commentary. (...) Previous studies indicate that he wrote only an exposition commentary on De sensu, but a more careful examination of the existing manuscripts shows that at least one of them contains a different work, here dubbed Quaestiones super librum De sensu et sensato.

It has become an academic self-evidence that space can only inadequately be conceptualized as a material or earth-bound base for social processes. This could commend a theoretical view of space as the outcome of action, which brings both social production practices and bodily deployment into focus. The action-theoretical perspective allows the constitution of space to be understood as taking place in perception. Not only are things alone perceived but also the relations between objects. This article develops a space-theoretical concept (...) according to which space is constituted through acts as the outcome of synthesis and positioning practices. This opens up a theoretical perspective defining atmospheres as an external effect, instantiated in perception, of social goods and human beings in their situated spatial order/ing. Exclusion and inclusion are accordingly comprehended in terms of perception of the attunement of places. With reference to Anthony Giddens, this article discusses how space can be understood as a duality of structural ordering and action elements. (shrink)

This volume focuses on philosophical problems concerning sense perception in the history of philosophy. It consists of thirteen essays that analyse the philosophical tradition originating in Aristotle’s writings. Each essay tackles a particular problem that tests the limits of Aristotle’s theory of perception and develops it in new directions. The problems discussed range from simultaneous perception to causality in perception, from the representational nature of sense-objects to the role of conscious attention, and from the physical/mental (...) divide to perception as quasi-rational judgement. -/- The volume gives an equal footing to Greek, Arabic, and Latin philosophical traditions. It makes a substantial contribution not just to the study of the Aristotelian analysis of sense perception, but to its reception in the commentary tradition and beyond. Thus, the papers address developments in Alexander of Aphrodisias, Themistius, Avicenna, John of Jandun, Nicole Oresme, and Sayf al-Din al-Amidi, among others. The result of this is a coherent collection that attacks a well-defined topic from a wide range of perspectives and across philosophical traditions. (shrink)

In physics, the temporal dimension has units of infinitesimally brief duration. Given this, how is it possible to perceive things, such as motion, music, and vibrotactile stimulation, that involve extension across many units of time? To address this problem, it is proposed that there is what is termed an “information construct of happening” (ICOH), a simultaneous representation of recent, temporally differentiated perceptual information on the millisecond time scale. The main features of the ICOH are (i) time marking, semantic labeling (...) of all information in the ICOH with ordinal temporal information and distance from what is informationally identified as the present moment, (ii) vector informational features that specify kind, direction, and rate of change for every feature in a percept, and (iii) connectives, information relating vector informational features at adjacent temporal locations in the ICOH. The ICOH integrates products of perceptual processing with recent historical information in sensory memory on the subsecond time scale. Perceptual information about happening in informational sensory memory is encoded in semantic form that preserves connected semantic trails of vector and timing information. The basic properties of the ICOH must be supported by a general and widespread timing mechanism that generates ordinal and interval timing information and it is suggested that state‐dependent networks may suffice for that purpose. Happening, therefore, is perceived at a moment and is constituted by an information structure of connected recent historical information. (shrink)

The Whorfian hypothesis has received support from recent findings in psychology, linguistics, and anthropology. This evidence has been interpreted as supporting the view that language modulates all stages of perception and cognition, in accordance with Whorf’s original proposal. In light of a much broader body of evidence on time perception, I propose to evaluate these findings with respect to their scope. When assessed collectively, the entire body of evidence on time perception shows that the Whorfian hypothesis has (...) a limited scope and that it does not affect early stages of time perception. In particular, all the available evidence shows that the scope of language modulation is limited in the case of time perception, and that the most important mechanisms for time perception are cognitive clocks and simultaneity windows, which we use to perceive the temporal properties of events. Language modulation has distorting effects, but only at later stages of processing or with respect to specific categorization tasks. The paper explains what is the role of these effects in the context of all the available evidence on time cognition and perception. (shrink)

The concept of simultaneous masking in visual field is discussed, in the light of classical examples, of the various kinds of the phenomenon, of a modal completion, of the figure/ground phenomenon, of ambiguous and reversible figures, of mimicry and camouflage and eventually of the complexity of the stimulus. There is some reference to masking in auditory field. The “reality” of the masked configuration is discussed, drawing the conclusion that it is perceptually unreal. The fact that the masking phenomenon cannot (...) take place without comparison between two perceptual acts – what we see at one moment and what we see a moment after LATER – and the fact that the masked configuration pops out with some surprise, lead to the conclusion that simultaneous masking in visual field is not a bare perceptual phenomenon, but a psychological process not unlike insight.

The time-lag argument seems to put some pressure on naïve realism to agree that seeing must happen simultaneously with what is seen; meanwhile, a wide-accepted empirical fact suggests that light takes time to transmit from objects at a distance to perceivers—which implies what is seen happened before seeing, and, accordingly, naïve realism must be false. In this paper, I will, first of all, show that the time-lag argument has in fact involves a misunderstanding concept of simultaneity: according to Special Relativity, (...) simultaneity is a matter of convention rather than a matter of fact, so, in principle, we can stipulate a perceptual conception of simultaneity, according to which what is seen is simultaneous with seeing. Secondly, the generalized time-lag argument has a mistaken view on the perceived events and perceiving; it has a doubtful assumption that these events are momentary in the mathematical sense. Such idealization is the main reason why we have the intuition that the time-lag effect of perceiving is in conflict with our ordinary perceptual experiences. Finally, I argue that the naïve realist account of the perceptual relation is a nontemporal constitutive relation; and hence naïve realism is compatible with the claim that we can perceive things as they were, and it should not be weakened by the time-lag argument.

The most fundamental question in Husserl’s unceasing analyses of inner time-consciousness is the possibility of the experience of succession or movement. This question, determining Husserl’s analyses already from his analysis in winter semester of 1904/1905, is based on a thesis that actuality of one moment of a succession precludes the actuality of any other. But if it is true that there is always only one actual moment, how is it possible to be aware of a succession that requires at least (...) two moments? Husserl’s general answer to this problem is that the moments that are not actually given are nevertheless somehow present in The aim of this paper is to show that Husserl’s adherence to the aforementioned thesis in his analyses implies a problem that undermines all his endeavors to explain the possibility of inner time-consciousness. The problem is that all the other non-present moments notwithstanding in what way they are apprehended are still static, and it is impossible to arrive at a proper succession from a multiplicity of simultaneously given static moments.

This chapter reviews the field of music perception and cognition, which is the area of cognitive psychology devoted to determining the mental mechanisms underlying our appreciation of music. The chapter begins with the study of pitch, including the constructive nature of pitch perception and the cognitive structures reflecting its simultaneous and sequential organization in Western tonal‐harmonic music. This is followed by reviews of temporal organization in music, and of musical performance and ability. Next, literature concerning the cognitive (...) neuroscience of music is examined, including studies of neuropsychology, neuroimaging, and event‐related potentials. The chapter concludes with a discussion of developmental music cognition, cross‐cultural music cognition, and the evolutionary psychology of music. (shrink)

In the perceptual learning of lexical tones, an automatic and robust attention-to-phonology system enables native tonal listeners to adapt to acoustically non-optimal speech, such as phonetic conflicts in daily communications. Previous tone research reveals that non-native listeners who do not linguistically employ lexical tones in their mother tongue may find it challenging to attend to the tonal dimension or integrate it with the segmental features. However, it is unknown whether the attentional interference initially caused by a maternal attentional system would (...) continue influencing the non-optimal tone perception for simultaneous bilingual teenagers. From an endpoint in the age of language acquisition, we investigate whether the tone-specific attention mechanism developed by the Urdu-Cantonese simultaneous bilinguals is automatic enough to assist them in adapting to a phonetically-conflicting environment. Three groups of teenagers engaged in a four-condition ABX task: Urdu-Cantonese simultaneous bilinguals, Cantonese native listeners, and Urdu-speaking, late learners of Cantonese. The results showed that although the simultaneous bilinguals could phonologically process Cantonese tones in a Cantonese-like way under a conflict-free listening condition, they still failed in adapting to the phonetic conflicts, especially the segment-induced ones. It thus demonstrated that the simultaneous exposure and years of regular education in Hong Kong local schools still could not automatically guarantee simultaneous bilingual processing of Cantonese tones. In interpreting the findings, it hypothesized that, except for simultaneous exposure, the development of a tone-specific attention mechanism is also likely to be L1-inhibitory, tone experience-driven, and language-specific for simultaneous bilinguals.

The article provides a comparative analysis of the perception of time in Europe and China. Time is considered as one of the fundamentals of mentality. The author presents the specifics of mythological time, distinguishing sacred and profane times and analyzing the correlation between time, space, things, and their repetition. European logos time, which becomes mainstream in Modern Times, is examined. The article describes the postmodern period that took shape in the 20th and early 21st centuries. The formation and contemporary (...) image of time in China is traced in detail. This perception of time suddenly turns out to be the most relevant to today’s needs: in Chinese culture, time and space are closely connected, linearity is combined with cyclicality, involvement is combined with distancing, immovability and the ability to wait for the right moment – with an instant reaction. In Chinese culture, innovations are introduced under the guise of tradition, and activism, which has always been especially emphasized as the specificity of the modern Europe, as it turns out, is the most important characteristic of the Chinese. Under modern “network” conditions, the substantial understanding of things, which is characteristic of European culture, has given way to a networking perception, which is specific to the Chinese. This is a network in which interactions are carried out simultaneously and in different directions. By itself, a comparative analysis of mentalities yields important results and allows to draw far-reaching conclusions that are essential for understanding both the European and Chinese visions of the world. In conclusion, it becomes clearer what features of the Chinese mentality made possible not only the entry of China into the group of developed countries but also its transformation into one of the leaders among the world powers.

We seem to experience a world abounding with events that exhibit dynamic temporal structure; birds flying, children laughing, rain dripping from an eave, melodies unfolding, etc. Seeing objects in motion, hearing and communicating with sound, and feeling oneself move are such common everyday experiences that one is unlikely to question whether humans are capable of perceiving temporal properties and relations. Despite appearing pre-theoretically uncontroversial, there are longstanding and contentious debates concerning the structure of such experience, how temporal perception works, (...) and even whether the perception of change, motion, and succession is possible. The overarching goal of my project is to develop a comprehensive model of temporal perception that does justice to the apparent phenomenology, explains how perception functions to represent temporally structured targets, and generates empirically-informed hypotheses for how such perception is neuro-cognitively realized. I also defend my model against the challenges of anti-realist competitors whom deny the possibility of perceiving temporal relations between non-simultaneous events. (shrink)

Codes of ethics and conduct have become common in UK organisations. This paper explores how such codes are understood and responded to by those whom the codes seek to influence. The study is an interpretative one, based on interview material, in which a dialectical pattern is seen in employees’ reactions to codes. Initial contradictions are found in codes of ethics (which claim to give employees space in which to exercise their integrity, but simultaneously are seen as impugning employees’ moral status) (...) and in codes of conduct (which require a loyal adherence to rules that interferes with wider loyalties). These tensions create perceptions of a two‐tier system in organisations in which core employees are subject to codes of ethics that are loosely applied, but non‐core staff are subject to codes of conduct that are strictly applied. However, even core staff are aware of a dialectical contradiction in their position. They believe that loyalty to the organisation is the price they pay for being allowed freedom of integrity by their organisations, but that the price they have to pay for showing integrity may be breaking faith with their organisations. This chiasmus of integrity and loyalty represents a difficulty for the project of improving standards of corporate citizenship. The use of this trope and other rhetorical figures to exemplify processes of understanding and interpretation in organisations is discussed. (shrink)

According to the received view in the philosophical literature on pictorial perception, when perceiving an object in a picture, we perceive both the picture’s surface and the depicted object, but the surface is only unconsciously represented. Furthermore, it is suggested, such unconscious representation does not need attention. This poses a crucial problem, as empirical research on visual attention shows that there can hardly be any visual representation, conscious or unconscious, without attention. Secondly, according to such a received view, when (...) looking at a picture aesthetically, one both consciously represents and visually attends to both the depicted object and the picture’s surface simultaneously. Thus, contra the empirical research on attention, only conscious visual representations are coupled, by such current view, with attention. And this clearly poses a second problem, as this philosophical account is not in tune with what vision science tells us about the functioning of our visual system. Furthermore, this raises another crucial problem, namely, that of explaining why aesthetic experience of pictures does not feel odd or conflicting, since, as previously noted in the philosophical literature, and contra the received view, if we are simultaneously consciously perceiving both the picture’s surface and the depicted object, there seems to be two things, at the same time, in the foreground of one’s visual consciousness. But, if so, as suggested, this would lead to a conflicting spatial visual experience. This paper offers a new description of the role of visual attention in picture perception, which explains the difference between the usual and the aesthetic way of perceiving a depicted object, without facing the problems reported above. A crucial role in our new account is played by the notion of unconscious attention, the distinction between focal and distributed, as well as top-down and bottom-up visual attention and the relationship between visual attention and visual consciousness. The paper, thus, offers the first theory concerning the exercise of visual attention in pictorial perception that is both philosophically rigorous and empirically reliable. (shrink)

Kant's response to ‘Hume's problem’ in his analysis of the a priori structure of causality as law-governed succession in the Second Analogy of Experience has unquestionably overshadowed the account of simultaneity (Zugleichsein), which follows in the Third Analogy. The analysis of simultaneity in the first Critique relies entirely upon that of succession and is ultimately no more than a more complicated variant of the causal dependence of substances: two objects are experienced as simultaneous only when each of those objects (...) grounds some determination of the other, that is when they are reciprocally determined in dynamic community. By investigating Kant's remark in the third Critique that the experience of the sublime “makes simultaneity intuitable” this paper develops a Kantian analysis of simultaneity that is irreducible to the more prominent analysis of causal succession. This more robust account of simultaneity is then seen to play an essential role in the constitution of the objects of perception (and not only the regulation of their relations) as thematized in the Axioms of Intuition in the Critique of Pure Reason.

The question I am interested in is this. What exactly is the role of conscious experience in the acquisition of knowledge on the basis of perception? The problem here, as I see it, is to solve simultaneously for the nature of this experience, and its role in acquiring and sustaining the relevant beliefs, in such a way as to vindicate what I regard as an undeniable datum, that perception is a basic source of knowledge about the mind-independent world, (...) in a sense of ‘basic’ which is also to be elucidated. I shall sketch the way in which I think that this should be done. In section I, I argue that perceptual experiences must provide reasons for empirical beliefs. In section II, I explain how they do so. My thesis is that a correct account of the sense in which perceptual experiences are experiences of mind-independent things is itself an account of the way in which they provide peculiarly basic reasons for beliefs about the world around the perceiver.

Audiovisual interaction in speech perception is well defined in adults. Despite the large body of evidence suggesting that children are also sensitive to visual input, very few empirical studies have been conducted. To further investigate whether visual inputs influence auditory perception of phonemes in preschoolers in the same way as in adults, we conducted an audiovisual identification test. The auditory stimuli were presented either in an auditory condition only or simultaneously with a visual presentation of the articulation of (...) the vowel /e/ or /ø/. The results suggest that, although all participants experienced visual influence on auditory perception, substantial individual differences exist in the 5- to 6-year-old group. While additional work is required to confirm this hypothesis, we suggest that auditory and visual systems are developing at that age and that multisensory phonological categorization of the rounding contrast took place only in children whose sensory systems and sensorimotor representations were mature.

Purpose This study aims to explore how the public perceives the effectiveness of surveillance technology, and how people’s views on privacy and their views on effectiveness are related. Likewise, it looks at the relation between perceptions of effectiveness and opinions on the acceptable cost of surveillance technology. Design/methodology/approach For this study, surveys of Dutch students and their parents were conducted over three consecutive years. Findings A key finding of this paper is that the public does not engage in a trade-off (...) neither with regard to privacy-effectiveness nor with effectiveness-cost, but rather expects all three elements to be achieved simultaneously. This paper also found that the correlation between perceived effectiveness and perceived privacy was stronger for parents than for students. Research limitations/implications Participants for this study were exclusively in The Netherlands. Survey questions on the effectiveness of surveillance technology focused on one type of technology, and on private mobile device use in two scenarios. Social implications The public’s perceptions of the effectiveness of surveillance technology potentially influence its acceptance of the technology, which, in turn, can affect the legitimacy and use of the technology. Originality/value Within the much-discussed privacy-security debate lies a less-heard debate – that of the effectiveness of the surveillance technology in question. The public is one actor in this debate. This study examines the public’s perceptions of this less-heard debate. (shrink)

Merleau-Ponty’s phenomenology of perception comprises two main levels of analysis: the description of the general foundation upon which all human perception occurs and that of the lived, situated aspects of perception, as experienced by individuals. These ‘structural’ and ‘situated’ accounts of perception assume, respectively, the existence of a pre-personal body, which all human beings possess in principle, and of a historical body, which is the product of an individual’s ‘synchronization’ with the world. A comprehensive and faithful (...) description of human perceptual experience must contain, simultaneously, the general, structural, individual, and situational elements involved in perception. It has also to show the ways in which these elements impact each other, leading to distinct outcomes. I propose, here, a situated account of perception that fulfills these requisites while confirming Merleau-Ponty’s insights and descriptions empirically, through cases of perceptual skill and learning in a large industrial plant near the Amazon rainforest in Brazil.

In an essay entitled ‘The Nobility of Sight’, Hans Jonas argues that ‘[s] ince the days of Greek philosophy sight has been recognized as the most excellent of senses’ (Jonas, 1954, p.507). Seeking to account for the historical elevation of vision over other forms of sensory engagement with the world, Jonas contends that ‘[t]he unique distinction of sight consists in what we may call the image performance, where “image” implies three characteristics: (1) simultaneity in the presentation of a manifold; (2) (...) neutralization of the causality of sense-affection; (3) distance in the spatial and mental senses’ (ibid.). In the case of (1), what distinguishes sight from other senses is the fact that it can give us both dynamic and static reality: our eyes can survey a whole field of possible percepts as well as focus directly upon a fixed object (ibid., pp.508–9). In the case of (2), what further marks out vision is that it does not require the perceiver and the object of perception to be directly engaged — the ‘dynamic’ relation between the two is, in Jonas’ words, ‘neutralized’ (ibid., p.514). And in the case of (3), seeing’s inimitability is also guaranteed by its being ‘the only sense in which the advantage lies not in proximity but in distance: the best view is by no means the closest view’ (ibid., pp.517–8).

In this paper, we study the interactional organization of an instructed object exploration among sighted and visually impaired people (VIPs) in order to contribute to studies of instructional activities and the observable accomplishment of haptic perception. We do this by showing the situated, interactional, and co-operative organization of achieving object understanding. We focus on the dynamics of haptic perception as being reliant on instructions, while at the same time being an observable production that furnishes further instructions. We show (...) the organization of visual and verbal instructions versus the touching of objects for haptic perception. Based on ethnomethodological conversation analysis of video data, we study a VIP’s haptic actions in interaction with a professional, sighted ICT consultant who provides instructions on what an object is and what it can do. We show how the instructions are sequentially adjusted to make them relevant for a simultaneous, emerging exploration in which the VIP uses their hands and fingers to perceive very specific details of the object. We argue that achieving object understanding is accomplished in and through the fine-tuned coordination of haptic exploration, both as a response to verbal instructions and also as a means of conveying perception-related actions, which the ICT uses to build new actions. The paper thus makes a case for instructed and distributed haptic perception as observable in social interaction and as a resource for building object understanding within phenomenal fields.

Inter-species variation in colour perception poses a serious problem for the view that colours are mind-independent properties. Given that colour perception varies so drastically across species, which species perceives colours as they really are? In this paper, I argue that all do. Specifically, I argue that members of different species perceive properties that are determinates of different, mutually compatible, determinables. This is an instance of a general selectionist strategy for dealing with cases of perceptual variation. According to selectionist (...) views, objects simultaneously instantiate a plurality of colours, all of them genuinely mind-independent, and subjects select from amongst this plurality which colours they perceive. I contrast selectionist views with relationalist views that deny the mind-independence of colour, and consider some general objections to this strategy. (shrink)

The traditional problem of incontinence raises the question of whether there is any way to account for action contrary to judgment. When one acts, rather than only being acted upon by circumstances, the action is explained in terms of the reasons for action one judges oneself to have. It therefore seems impossible to explain action that iscontrary to such judgment. This paper examines the question of how such explanation would be possible. After excluding accounts that either eliminate incontinence or render (...) it inexplicable, I argue that genuine incontinence would require three components: first, a distinction between the types of judgments simultaneously present in the agent; second, the Aristotelian idea that not all of those types of judgments can be directly action-guiding; and third, that the judgments that are action-guiding can be pre-conceptual perceptions. I then use elements of Collingwood's aesthetics to make the case that although such pre-conceptual perceptions would not be propositional judgments and the relationship between them and the behaviors of the agent could not be causal, those behaviors could still qualify as incontinent actions.

In a seminal 1977 article, Rumelhart argued that perception required the simultaneous use of multiple sources of information, allowing perceivers to optimally interpret sensory information at many levels of representation in real time as information arrives. Building on Rumelhart's arguments, we present the Interactive Activation hypothesis—the idea that the mechanism used in perception and comprehension to achieve these feats exploits an interactive activation process implemented through the bidirectional propagation of activation among simple processing units. We then examine (...) the interactive activation model of letter and word perception and the TRACE model of speech perception, as early attempts to explore this hypothesis, and review the experimental evidence relevant to their assumptions and predictions. We consider how well these models address the computational challenge posed by the problem of perception, and we consider how consistent they are with evidence from behavioral experiments. We examine empirical and theoretical controversies surrounding the idea of interactive processing, including a controversy that swirls around the relationship between interactive computation and optimal Bayesian inference. Some of the implementation details of early versions of interactive activation models caused deviation from optimality and from aspects of human performance data. More recent versions of these models, however, overcome these deficiencies. Among these is a model called the multinomial interactive activation model, which explicitly links interactive activation and Bayesian computations. We also review evidence from neurophysiological and neuroimaging studies supporting the view that interactive processing is a characteristic of the perceptual processing machinery in the brain. In sum, we argue that a computational analysis, as well as behavioral and neuroscience evidence, all support the Interactive Activation hypothesis. The evidence suggests that contemporary versions of models based on the idea of interactive activation continue to provide a basis for efforts to achieve a fuller understanding of the process of perception.

Despite the immense societal importance of ethically designing artificial intelligence, little research on the public perceptions of ethical artificial intelligence principles exists. This becomes even more striking when considering that ethical artificial intelligence development has the aim to be human-centric and of benefit for the whole society. In this study, we investigate how ethical principles are weighted in comparison to each other. This is especially important, since simultaneously considering ethical principles is not only costly, but sometimes even impossible, as developers (...) must make specific trade-off decisions. In this paper, we give first answers on the relative importance of ethical principles given a specific use case—the use of artificial intelligence in tax fraud detection. The results of a large conjoint survey suggest that, by and large, German respondents evaluate the ethical principles as equally important. However, subsequent cluster analysis shows that different preference models for ethically designed systems exist among the German population. These clusters substantially differ not only in the preferred ethical principles but also in the importance levels of the principles themselves. We further describe how these groups are constituted in terms of sociodemographics as well as opinions on artificial intelligence. Societal implications, as well as design challenges, are discussed.

Schizophrenia is associated with a series of visual perception impairments, which might impact on the patients’ every day life and be related to clinical symptoms. However, the heterogeneity of the visual disorders make it a challenge to understand both the mechanisms and the consequences of these impairments, i.e., the way patients experience the outer world. Based on earlier psychiatry literature, we argue that issues regarding time might shed a new light on the disorders observed in patients with schizophrenia.We will (...) briefly review the mechanisms involved in the sense of time continuity and clinical evidence that they are impaired in patients with schizophrenia.We will then summarize a recent experimental approach regarding the coding of time-event structure in time, namely the ability to discriminate between simultaneous and asynchronous events. The use of an original method of analysis allowed us to distinguish between explicit and implicit judgments of synchrony.We showed that for SOAs below 20ms neither patients nor controls fuse events in time. On the contrary subjects distinguish events at an implicit level even when judging them as synchronous. In addition, the implicit responses of patients and controls differ qualitatively. It is as if controls always put more weight on the last occurred event, whereas patients have a difficulty to follow events in time at an implicit level. In patients, there is a clear dissociation between results at short and large asynchronies, that suggest selective mechanisms for the implicit coding of time-event structure. These results might explain the disruption of the sense of time continuity in patients.We argue that this line of research might also help us to better understand the mechanisms of the visual impairments in patients and how they see their environment.

Can psychology explain the qualitative content of experience? A persistent philosophical objection to that discipline is that it cannot. Qualitative states or 'qualia' are argued to have characteristics which cannot be explained in terms of their relationships to other psychological states, stimuli, and behavior. Since psychology is confined to descriptions of such relationships, it seems that psychology cannot explain qualia. A paradigm case of qualia is provided by simultaneous color contrast effects, in which a neutral grey patch is made (...) to look reddish by being enclosed in a green surround. If the qualia based objections are sound, psychology ought not to be able to explain simultaneous color contrast; but psychology at least seems to be able quite successfully to explain those effects. This paper analyzes the logic of psychological explanations of simultaneous color contrast effects, and the import of various qualia based objections to those explanations. I argue that the qualia objections do not demonstrate any explanatory inadequacy in existing psychological explanations of 'looks'. Psychology succeeds in explaining at least some qualia. In a more positive vein, I argue that once the structure of such explanations is sufficiently understood, a place can be found for qualia within the emerging scientific account of color perception. The resulting account can deal with many of the traditional perplexities over qualia. (shrink)

A cognition is a psychological property distinct from the properties of a person's body and objects of sensory experience. A cognition rests or occurs in a self, and for only an instant before giving way to another cognition, each having as content, when veridical, intersubjective objects other than itself. But a cognition is also causally continuous with its objects—in the one direction, through the operation of the sense organs, sight, hearing, and so on, and, in the other, in having a (...) causal role in action undertaken voluntarily. This paper sketches the Nyāya theory of perception with special attention to the arguments of the "New" or late Nyāya philosopher of the fourteenth century, Gangesa, in addressing two thorny areas of the Nyāya picture: (1) focus wanted and unwanted along with apparent cognitive simultaneity in a synthesis of sensory information deriving from the operation of more than one sense organ, and (2) the peculiar sensory connection involved in perception of future instances of universals, illusorty perception, and in recognition of someone or something that one has encountered before.

Participants who were unable to detect familiarity from masked 17 ms faces did report a vague, partial visual percept. Two experiments investigated the relative strength of the visual percept generated by famous and unfamiliar faces, using masked 17 ms exposure. Each trial presented simultaneously a famous and an unfamiliar face, one face in LVF and the other in RVF. In one task, participants responded according to which of the faces generated the stronger visual percept, and in the other task, they (...) attempted an explicit familiarity decision. The relative strength of the visual percept of the famous face compared to the unfamiliar face was moderated by response latency and participants’ attitude towards the famous person. There was also an interaction of visual field with response latency, suggesting that the right hemisphere can generate a visual percept differentiating famous from unfamiliar faces more rapidly than the left hemisphere. Participants were at chance in the explicit familiarity decision, confirming the absence of awareness of facial familiarity. (shrink)

In timing perception studies, the timing of one event is usually manipulated relative to another, and participants are asked to judge if the two events were synchronous, or to judge which of the two events occurred first. Responses are analyzed to determine a measure of central tendency, which is taken as an estimate of the timing at which the two events are perceptually synchronous. When these estimates do not coincide with physical synchrony, it is often assumed that the sensory (...) signals are asynchronous, as though the transfer of information concerning one input has been accelerated or decelerated relative to the other. Here we show that, while this is a viable interpretation, it is equally plausible that such effects are driven by shifts in the criteria used to differentiate simultaneous from asynchronous inputs. Our analyses expose important ambiguities concerning the interpretation of simultaneity judgement data, which have hitherto been underappreciated. (shrink)

In "The Incoherence of Whitehead’s Theory of Perception" (PS 9:94-104), Robert H. Kimball tries to show how Alfred North Whitehead’s account of perception is a failed attempt to reconcile two traditional theories of perception: phenomenological (or sense-data) theory and causal (or physiological) theory. Whitehead fails, Kimball argues, in two main ways. First because his notion of symbolic reference requires the simultaneous enjoyment of perceptions in the mode of presentational immediacy and causal efficacy. Kimball believes this experience (...) is, in principle, impossible and supports this claim by attacking Whitehead’s conception of causal efficacy and the experiential evidence used to support it. Whitehead’s second failure results from the first: Whitehead’s erroneous belief in the simultaneous enjoyment of the two modes of perception leads him to construct a theory of perception which is composed of two contradictory parts: realism and mediatism. In this essay, I will examine Kimball’s attack on causal efficacy and symbolic reference and show why Whitehead’s theory of perception is not susceptible to Kimball’s charge of incoherence. (shrink)

Holistic thinking involves four subconstructs: causality, contradiction, attention to the whole, and change. This holistic perspective varies across Eastern–Western cultures and genders. We theorize that holistic thinking reduces three domain-specific risk-taking behavioral intentions (ethical, financial, and health/safety) directly and indirectly through enhanced risk-taking attitudes. Our formative theoretical model treats the four subconstructs of holistic thinking as yoked antecedents and frames it in a proximal context of causes and consequences. We simultaneously explore the direct and indirect paths and test our model (...) across cultures, genders, and the combination of the two. For the entire sample (N = 531), holistic thinking negatively relates to risk intentions via enhanced risk perceptions. Across cultures, the indirect paths prevail among Chinese people (n = 284), and both direct and indirect paths triumph for Americans (n = 247). Across genders, the indirect paths exist for females, whereas the negative direct path (risk-raking attitudes → behavioral intentions) succeeds for males. Across cultures and genders, holistic thinking negatively relates to American males’ ethical risks the most but Chinese males’ financial risks the least. Risk-taking perceptions are negatively related to Chinese males’ ethical risks the most, but Chinese people’s (males/females) financial risks the least. Causality and change are vital for all contexts, attention to the whole for all males and Chinese males, and contradiction for Americans and all females. Holistic thinking has limits and is less robust than risk-taking perceptions in reducing risky behavioral intentions. Our practical implications help people make ethical, healthy, and wealthy decisions. (shrink)
