Perceptual representations pick out individuals and attribute properties to them. This paper considers the role of perceptual attribution in determining or guiding perceptual reference to objects. We consider three extant models of the relation between perceptual attribution and perceptual reference–all attribution guides reference, no attribution guides reference, or a privileged subset of attributions guides reference–and argue that empirical evidence undermines all three. We then defend a flexible-attributives model, on which the range (...) of perceptual attributives used to guide reference shifts adaptively with context. This model underscores the remarkable and dynamic intelligence of our perceptual capacities. We elucidate implications of the model for the boundary between perception and propositional thought.

The chapter deals with the notion of phenomenal realness, which was first systematically explored by Albert Michotte. Phenomenal realness refers to the impression that a perceptual object is perceived to have an autonomous existence in our mind-independent world. Perceptual psychology provides an abundance of phenomena, ranging from amodal completion to picture perception, that indicate that phenomenal realness is an independent perceptual attribute that can be conferred to perceptual objects in different degrees. The chapter outlines a theoretical (...) framework that appears particularly well-suited for dealing with corresponding phenomena. According to this framework, perception can be understood as a triggering of conceptual forms by sensor inputs. It is argued that the attribute of phenomenal realness is based on specific types of internal evaluation functions which deal with the segregation of causes conceived as ‘external’ from those conceived as ‘internal’. These evaluation functions integrate different internal sources of ‘knowledge’ about the potential causes for the activation of conceptual forms and provide markers by which conceptual forms can be tagged as ‘external world objects’.

This paper aims to provide an empirically informed sketch of how our perceptual capacities can interact with cognitive processes to give rise to new perceptual attributives. In section 1, I present ongoing debates about the reach of perception and direct focus toward arguments offered in recent work by Tyler Burge and Ned Block. In section 2, I draw on empirical evidence relating to language processing to argue against the claim that we have no acquired, culture-specific, high-level perceptual (...) attributives. In section 3, I turn to the cognitive dimension; I outline how cognitive procedures can be involved in the acquisition of what ought to, nonetheless, be recognized as genuinely perceptual capacities. Finally, in section 4, I argue for the importance of distinguishing these conclusions from more familiar and radical claims about rampant “cognitive penetration” into the perceptual domain. (shrink)

I argue that perceptual content is always affected by the allocation of one’s attention. Perception attributes determinable and determinate properties to the perceived scene. Attention makes (or tries to make) our perceptual attribution of properties more determinate. Hence, a change in our attention changes the determinacy of the properties attributed to the perceived scene.

A straightforward way of thinking about perception is in terms of perceptual representation. Perception is the construction of perceptual representations that represent the world correctly or incorrectly. This way of thinking about perception has been questioned recently by those who deny that there are perceptual representations. This article examines some reasons for and against the concept of perceptual representation and explores some potential ways of resolving this debate. Then it analyzes what perceptual representations may be: (...) if they attribute properties to entities, what are these attributed properties, and what are the entities they are attributed to.

Intentionalism about visual experiences is the view according to which the phenomenal character of a visual experience supervenes on the content of this experience. One of the most influential objections to this view is about blur: seeing a fuzzy contour clearly and seeing a sharp contour blurrily have different phenomenal character but the same content. I argue that this objection does not work if we understand perceptual content simply, and not particularly controversially, as partly constituted by the sum total (...) of perceptually attributed properties, some determinable, some determinate.

Many recent cognitive studies reveal that human cognition is inherently perceptual, sharing systems with perception at both the conceptual and the neural levels. This paper introduces Barsalou's theory of perceptual symbols and explores its implications for philosophy of science. If perceptual symbols lie in the heart of conceptual processing, the process of attribute selection during concept representation, which is critical for defining similarity and thus for comparing taxonomies, can no longer be determined solely by background beliefs. The (...) analogous nature of perceptual symbols and the spatial nature of intraconceptual relations impose new constraints on attribute selection. These constraints help people with different background beliefs select compatible attributes, which constitute a common "platform" for taxonomy comparison. (shrink)

The chapter argues from an ethology-inspired internalist perspective that ‘colour’ is not a homogeneous and autonomous attribute, but rather plays different roles in different conceptual forms underlying perception. It discusses empirical and theoretical evidence that indicates that core assumptions underlying orthodox conceptions are grossly inadequate. The assumptions pertain to the idea that colour is a kind of autonomous and unitary attribute. It is regarded as unitary or homogeneous by assuming that its core properties do not depend on the type of (...) ‘perceptual object’ to which it pertains and that‘colour per se’ constitutes a natural attribute in the functional architecture of the perceptual system. It is regarded as autonomous by assuming that it can be studied in isolation of other perceptual attributes. More generally, the chapter argues on the bases of corresponding empirical and theoretical evidence that perception cannot be understood as the ‘recovery’ of physical world structure from sensory structure by input-based computational processes. Rather, the sensory input serves as a kind of sign for biologically relevant aspects of the external world that activates biologically given conceptual forms with their internal parameters. Although the sensory input is a causally necessary requirement for the activation of conceptual forms, the perceptual computations triggered are under the control of an internal programme based on a set of conceptual forms.

Representationalists hold that perceptual experience is a conscious representational state with content, something which is accurate or inaccurate in certain conditions. The most common version of Representationalism takes perceptual content to be singular in the object-place and otherwise consisting of attribution of properties (Singularism/Attributionism). Schellenberg has recently developed a version on which perceptual content is singular even in the property-place in containing a de re mode of presentation of a property-instance (Particularism). In this paper, I show (...) that Particularism faces a version of the problem of the Unity of Perceptual Content. Namely, its supporters haven’t told us how objects can be bound together with property-instances into a content such that it represents them and has accuracy-conditions. Furthermore, I argue that Particularists face an in-principle obstacle in solving it. In contrast, Attributionists can solve the problem and that establishes their view as the only game in town.

Colour is, according to prevailing orthodoxy in perceptual psychology, a kind of autonomous and unitary attribute. It is regarded as unitary or homogeneous by assuming that its core properties do not depend on the type of ‘perceptual object’ to which it pertains and that‘colour per se’ constitutes a natural attribute in the functional architecture of the perceptual system. It is regarded as autonomous by assuming that it can be studied in isolation of other perceptual attributes. These (...) assumptions also provide the pillars for the technical field of colorimetry, and have proved very fruitful for neurophysiological investigations into peripheral colour coding. They also have become, in a technology-driven cultural process of abstraction, part of our common-sense conception of colour. With respect to perception theory, however, both assumptions are grossly inadequate, on both empirical and theoretical grounds. All the same, the idea of an internal homogeneous and autonomous attribute of ‘colour per se’, mostly taken not as an empirical hypothesis but as a kind of truism, became a guiding idea in perceptual psychology. Here, it has impeded the identification of relevant theoretical issues and consequently has become detrimental for the development of explanatory frameworks for the role of ‘colour’ within the structure of our perceptual system. The chapter argues that enquiries into colour perception cannot be divorced from general enquiries into the structure of the conceptual forms underlying perception. (shrink)

Many philosophers and brain scientists hold that explaining consciousness is one of the major outstanding problems facing modern science today. One type of consciousness in particular—phenomenal consciousness—is thought to be especially problematic. The reasons given for believing that this phenomenon exists in the first place, however, often hinge on the claim that its existence is simply obvious in ordinary perceptual experience. Such claims motivate the study of people's intuitions about consciousness. In recent years a number of researchers in experimental (...) philosophy of mind have begun to shed light on this area, investigating how people understand and attribute those mental states that have been thought to be phenomenally conscious. In this article, we discuss the philosophical concept of phenomenal consciousness and detail the work that has been done on the question of whether lay people have this concept. (shrink)

Young and colleagues . Betwixt life and death: case studies of the Cotard delusion. In P. W. Halligan & J. C. Marshall , Method in madness: Case studies in cognitive neuropsychiatry. Mahway, NJ: Lawrence Erlbaum Associates.) have suggested that cases of the Cotard delusion result when a particular perceptual anomaly occurs in the context of an internalising attributional style. This hypothesis has not previously been tested directly. We report here an investigation of attributional style in a 24-year-old woman with (...) Cotard delusion . LU’s attributional style was assessed using the Internal, Personal and Situational Attributions Questionnaire . A new measure of causal locus: the internal, personal and situational attributions questionnaire. Personality and Individual Differences, 20, 261–264.). LU showed a significantly greater proportion of internalising attributions than the control group, both overall and for negative events specifically. The results obtained thus support an association of Cotard delusion with an internalising attributional style, and are therefore consistent with the account of Young and colleagues. The potential brain basis of Cotard delusion is discussed. (shrink)

Call the idea that states of perceptual awareness have intentional content, and in virtue of that aim at or represent ways the world might be, the ‘Content View.’ I argue that though Kant is widely interpreted as endorsing the Content View there are significant problems for any such interpretation. I further argue that given the problems associated with attributing the Content View to Kant, interpreters should instead consider him as endorsing a form of acquaintance theory. Though perceptual acquaintance (...) is controversial in itself and in attribution to Kant, it promises to make sense of central claims within his critical philosophy. (shrink)

Is there some general reason to expect organisms that have beliefs to have false beliefs? And after you observe that an organism occasionally occupies a given neural state that you think encodes a perceptual belief, how do you evaluate hypotheses about the semantic content that that state has, where some of those hypotheses attribute beliefs that are sometimes false while others attribute beliefs that are always true? To address the first of these questions, we discuss evolution by natural selection (...) and show how organisms that are risk-prone in the beliefs they form can be fitter than organisms that are risk-free. To address the second question, we discuss a problem that is widely recognized in statistics – the problem of over-fitting – and one influential device for addressing that problem, the Akaike Information Criterion (AIC). We then use AIC to solve epistemological versions of the disjunction and distality problems, which are two key problems concerning what it is for a belief state to have one semantic content rather than another.

Traditional debates between semantic temporalists and eternalists appeal to the efficacy of temporal operators and the intuitive (in)validity of instances of temporal reasoning. In this paper, I argue that such debates are inconclusive at best and that under-explored arguments concerning perceptual experience, memory, and knowledge offer more productive means of advancing debates between temporalists and eternalists and rendering salient several significant potential costs and benefits of these views.

Entities that are, in ordinary perceptual situations, veridically presented as objects can be called ‘perceptual objects’. In the philosophical literature, one can find various approaches to the crucial features that distinguish the class of perceptual objects. While these positions differ in many respects, they share an important general feature: they all characterize perceptual objects as largely subject-independent. More specifically, they do not attribute a significant constitutive role to the perceptual relation connecting a fragment of the (...) environment with a perceiving subject. Fragments of the environment are perceptual objects no matter whether they stand in a perceptual relation to any subject, mainly by virtue of having a certain physical structure. I question this common assumption, relying on Green’s ( 2019 ) definition of perceptual objects, arguing that a proper theory of perceptual objects should accommodate the constitutive role of perceptual relations. This is because there exist fragments of the environment that are perceptual objects only when they stand in a perceptual relation to a subject. (shrink)

Pessoa et al. (1998a) summarize a wide body of data suggesting that perceptual filling-in phenomena can be attributed to neural filling-in processes. However, they reject, on philosophical grounds, the hypothesis that filled-in representations in the brain are the immediate substrate of visual percepts. It is proposed in this commentary that resonant binding between distributed cortical areas may instead be the crucial ingredient for conscious visual percepts, and that filling-in processes may facilitate the interactions between behaving organisms and object surfaces. (...) These suggestions circumvent some of the philosophical problems associated with the idea of localized visual representations. (shrink)

Computational neuroscience attributes coloured areas and other perceptual qualia to calculations that are realizable in multiple cellular forms. This faces serious issues in explaining how the various qualia arise and how they bind to form overall perceptions. Qualia may instead be neuroelectrical. Growing evidence indicates that perceptions correlate with neuroelectrical activity spotted by locally activated EEGs, the different qualia correlate with the different electrochemistries of unique detector cells, a unified neural-electromagnetic field binds this activity to form overall perceptions, and (...) this field interacts with sensory circuits to help attentively guide perception. The coloured areas in images may thus be seated in the electrochemistry of unique cells, while constancy mechanisms and other multiply realizable computations just help refine these images behind the scenes. This theory is ultimately testable. (shrink)

Part of a symposium on Christopher Hill's book, Perceptual experience. Hill argues that perceptual experiences typically represent objects as having exotic properties that he calls Thouless properties. This and his representational pluralism allow him to attribute less perceptual error than the view that experiences represent simple relational properties (only). However, I think it is plausible that perceptual systems do make these sorts of errors, which although pervasive and systematic, are relatively subtle and perfectly explicable. I also (...) express some concerns about representational pluralism, especially in the context of a representationalist view of the phenomenal character of experience. (shrink)

According to proponents of the sensorimotor contingency theory of perception (Hurley & Noë 2003, Noë 2004, O’Regan 2011), active control of camera movement is necessary for the emergence of distal attribution in tactile-visual sensory substitution (TVSS) because it enables the subject to acquire knowledge of the way stimulation in the substituting modality varies as a function of self-initiated, bodily action. This chapter, by contrast, approaches distal attribution as a solution to a causal inference problem faced by the subject’s (...) perceptual systems. Given all of the available endogenous and exogenous evidence available to those systems, what is the most probable source of stimulation in the substituting modality? From this perspective, active control over the camera’s movements matters for rather different reasons. Most importantly, it generates proprioceptive and efference-copy based information about the camera’s body-relative position necessary to make use of the spatial cues present in the stimulation that the subject receives for purposes of egocentric object localization.

The objective of this paper is to analyse the concept of skilful action underlying the studies of perceptual experience, especially the visual one, from the perspective of the theory of direct perception. The problem we propose to investigate can be formulated as follows: what are the possible contributions of the concept of affordance to understand the nature of skilful actions generally attributed to processes resulting from internal representations or mental models? In particular, we will try to investigate to what (...) extent the concept of social affordance can help to understand aspects of complex skilful actions that involve capacities considered as deriving from the possession of a Theory of Mind. We will try to show that the perspective of the ecological psychology of direct perception allows to understand aspects of human skilled action, especially of a collaborative nature, from a conception of perceptual experience that involves information intrinsically significant.

The problem of other minds has a distinguished philosophical history stretching back more than two hundred years. Taken at face value, it is an epistemological question: it concerns how we can have knowledge of, or at least justified belief in, the existence of minds other than our own. In recent decades, philosophers, psychologists, neuroscientists, anthropologists and primatologists have debated a related question: how we actually go about attributing mental states to others (regardless of whether we ever achieve knowledge or rational (...) justification in this domain). Until the mid-nineties, the latter debate – which sometimes goes under the name of the “mindreading” debate – was characterized by a fairly clear-cut opposition between two theoretical outlooks: “theory-theory” (TT) and “simulation theory” (ST). Theory-theorists typically argued that we attribute mental states to others on the basis of a “theory of mind” that is either constructed in early infancy and subsequently revised and modified (Gopnik 1996), or else is the result of maturation of innate mindreading “modules” (Baron-Cohen 1995).

This article traces the philosophical idea of self-perception from the times of ancient Stoicism to the thirteenth century by analyzing the views of Seneca, Augustine, and Olivi. The central argument is that they defend the same idea according to which self-preservation and the appropriate use of one’s body requires awareness thereof, despite the obvious contextual differences and the uncertainty of direct historical connections between the authors. They think that this kind of self-awareness does not belong only to human beings, because (...) irrational animals need to perceive their bodies, the functions of their bodily parts, and to perceive themselves as living beings in order to act appropriately and survive. The attribution of self-perception to animals is based on a distinction between the experiential awareness of the soul and the intellectual understanding of its essence, a distinction postulated by all three authors. The philosophical affinities between their views show that ideas that originate in Stoic thought were transmitted, directly or indirectly, to medieval philosophical psychology. (shrink)

<The definitive version is available at www.blackwell-synergy.com > -- In this paper I carve out a space between the concept of "the object" and the seemingly endless ways in which "the object" can be represented pictorially. I will call the aspect of the pictorial representation which is made possible by this space, the pictorial representation's "style". I will explore this space by drawing upon theories of pictorial representation, leaving out, for the sake of my purposes here, a consideration of the (...) artist's intention. That an attribution of "style" can be comprehensive while leaving out a consideration of artists' intentions, I will argue by adopting the conceptual framework of Paul Thom's theory of interpretation. Before embarking on my project, I begin with a brief overview of the rather slippery notion of "style". (shrink)

There is considerable debate in comparative psychology and philosophy over whether nonhuman animals can attribute beliefs. The empirical studies that suggest that they can are shown to be inconclusive, and the main philosophical and empirical arguments that purport to show they cannot are shown to be invalid or weak. What is needed to move the debate and the field forward, it is argued, is a fundamentally new experimental protocol for testing belief attribution in animals, one capable of distinguishing genuine (...) belief-attributing subjects from their perceptual-state attributing and behavior-reading counterparts. Such a protocol is outlined and defended. The rest, it is argued, is in the hands of experimentalists. (shrink)

Two common strategies have dominated attempts to account for the nature of taste. On the one side, we have an affectivist understanding of taste where aesthetic attribution has to do with the expression of a subjective response. On the other side, we find a non-affectivist approach according to which to judge something aesthetically is to epistemically track its main aesthetic properties. Our main argument will show that neither emotion nor perception can explain the nature of aesthetic taste single-handedly. In (...) this paper, our principal aim is to examine the relationship between perceptual discernment and emotional sensibility as we find it in the process of ascribing aesthetic qualities. Is it the nature of the specific aesthetic property in question which determines the way in which perception and emotion are balanced in aesthetic attribution, or is it, rather, something about how our sensory skills operate? One of the notions we would like to explore in greater detail in this context is the idea of attunement, or the way in which aesthetic agents can align themselves to the content of an artwork o in order to better grasp its content and significance. According to our proposed picture, the exercise of taste involves an adjustment of one’s emotional sensibility to the aesthetic character of o. From here, we will posit both emotional and perceptual training as part of an agent’s aesthetic education in her use of aesthetic terms. (shrink)

The term ‘recalcitrant emotions’ refers to those cases where we feel an emotion that apparently contradicts our better judgements. For instance, one may be afraid of flying while claiming not to believe that it is dangerous. This phenomenon is commonly conceived as an objection to cognitivism, according to which emotions are based on the subject's beliefs, insofar as it would force us to ascribe to the subject who feels them an excessive degree of irrationality, comparing recalcitrant emotions to contradictory beliefs. (...) For this reason, many philosophers have developed perceptual theories which describe emotions as forms of perception, allowing us to explain recalcitrant emotions without attributing to the subject contradictory beliefs, treating them as perceptual illusions. Facing the most compelling of these attempts, the article shows that perceptual accounts fail to explain in what sense recalcitrant emotions (and people who feel them) are irrational, keeping the comparison with optical illusions, which are not. Having rebutted three popular perceptual proposals, I conclude that the analogy between emotions and perceptions is flawed and that the appeal of these theories lies on a surreptitious shift in the meaning of the term ‘perceive’.

A ‘Radical Simulationist’ account of how folk psychology functions has been developed by Robert Gordon. I argue that Radical Simulationism is false. In its simplest form it is not sufficient to explain our attribution of mental states to subjects whose desires and preferences differ from our own. Modifying the theory to capture these attributions invariably generates innumerable other false attributions. Further, the theory predicts that deficits in mentalizing ought to co-occur with certain deficits in imagining perceptually-based scenarios. I present (...) evidence suggesting that this prediction is false, and outline further possible empirical tests of the theory. (shrink)

We present two studies investigating the impact of causal perceptions and the moral emotions of anger, shame, and guilt on the justification of deviant workplace behavior. Study 1 tests our conceptual framework using a sample of undergraduate business students; Study 2 examines a population of practicing physicians. Results varied significantly between the two samples, suggesting that individual and contextual factors play an important role in shaping the perceptual and emotional processes by which individuals form reactions to undesirable affective workplace (...) events. Implications of these findings for the study of ethics, emotions, and attributions, as well as for promoting ethical behavior, are discussed. (shrink)

In recent years sense–datum theories have received much criticism, but there is one type of error frequently involved in the sense–datum concept which is in need of further consideration. This error consists in a category confusion of such a nature that what is properly regarded as perceptual mode is treated as though it were the attribute of a thing. The mode or manner of perception is mistakenly transferred to the sense–datum with results which a little careful reflection shows to (...) be absurd. In what follows a specific case of this error connected with the notion of phenomenal organization will be discussed. (shrink)

Open peer commentary on the article “Perception-Action Mutuality Obviates Mental Construction” by Martin Flament Fultot, Lin Nie & Claudia Carello. Upshot: The main goal of this commentary is to make more discriminative the comparison between enactive and ecological theories of perception. Emergence at the level of the animal-environment system might be playing the role attributed to mental construction in basic perceptual processes. If correct, this would render some forms of enactivism compatible with the theoretical tenets of the target article.

In social contexts, people are responsible for their actions and outcomes. Diffusion of responsibility is a well-known social phenomenon: people feel less responsible when performing an action with co-actors than when acting alone. In previous studies, co-actors reduced the participant’s responsibility attribution by making the cause of the outcomes ambiguous. Meanwhile, it is unclear whether the presence of co-actors creates diffusion of responsibility even in situations where it is “obvious” that both oneself and the co-actor are the causes of (...) an outcome. To investigate this potential diffusion of responsibility, we used a temporal binding task as a measure of causal attribution. Low TB effects indicate the enhancement of external attribution in perceptual processing for the action and outcomes. To investigate the influence of presence of a co-actor on causal attribution, participants were required to act under two experimental conditions: an ALONE condition or a TOGETHER condition. The only difference between the two conditions was whether the actions were shared. In addition, to make participants feel responsible, they were induced to feel guilt. In the High-harm condition, participants gave a financial reduction to a third party. When guilt was induced, participants showed lower TB effects in the TOGETHER condition compared to the ALONE condition. Our study suggests that actions with a co-actor change causal attributions even though the causes of the outcome are obvious. This may have implications for understanding diffusion of responsibility in inhumane situations. (shrink)

To investigate the possible dichotomy between the neurophysiological bases of perceptual transitions versus sustaining a particular percept over time, an fMRI study was conducted with subjects viewing fragmented pictures. Unlike most other perceptually unstable stimuli, fragmented pictures give rise to only one perceptual transition and a continuous period of sustained perception. Earlier research is inconclusive on the subject of which anatomical regions should be attributed to what temporal aspect of perception, and the aim of the present study was (...) to shed more light on the subject. In this study occipitotemporal and fronto-parietal regions were found to be activated for both aspects. However, regions in the medial-temporal lobe were activated specifically for transitions, whereas medial and dorsolateral prefrontal regions were activated specifically for sustained perception. These results provide further support for the theory that the initial creation of perceptual awareness and upholding perceptual awareness over time are separate processes involving different brain regions.

It has recently been pointed out that perceptual nonconceptualism admits of two different and logically independent interpretations. On the first (content) view, perceptual nonconceptualism is a thesis about the kind of content perceptual experiences have. On the second (state) view, perceptual nonconceptualism is a thesis about the relation that holds between a subject undergoing a perceptual experience and its content. For the state nonconceptualist, it thus seems consistent to hold that both perceptual experiences and (...) beliefs share the same (conceptual) content, but that for a subject to undergo a perceptual experience, the subject need not possess the concepts involved in a correct characterization of such content. I argue that the consistency of this position requires a non-Fregean notion of content that fails to capture the way the subject grasps the world as being. Hence state nonconceptualism leaves perceptual content attribution unsupported. Yet, on a characterization of content along the relevant (neo-Fregean) lines, this position would become incoherent, as it would entail that a subject could exercise cognitive abilities she doesn’t possess. I conclude that, given the notion of content demanded by the debate, the state view does entail the content view after all. (shrink)

The focus of this commentary is what Andy Clark takes to be the most groundbreaking of the philosophical import of the ‘bidirectional hierarchical model of brain functions’, namely, the claim that perceptual representations represent probabilities. This is what makes his account Bayesian and this is a philosophical or theoretical conclusion that neuroscientists and psychologists are also quick and happy to draw. My claim is that nothing in the ‘bidirectional hierarchical models of brain functions’ implies that perceptual representations are (...) probabilistic, or that they represent or ‘encode probability density distributions’. There is a much more parsimonious way of describing the representations in the bidirectional hierarchical model of brain functions: they attribute properties to objects (or to the perceived scene) that are not fully determinate.

Topology has been characterized as an unsuitable mathematical framework for the investigation of geometric-perceptual phenomena. This has been attributed to the highly abstract nature of topology leading to failures in tasks such as making distinctions between geometrical figures (e.g., a cube versus a sphere) in which the human perceptual system succeeds easily. An alternative thesis is proposed on both philosophical and empirical grounds. The present analysis applies the Müller-Lyer (ML) illusion as a method of investigation to examine the (...) suitability of topology in raising questions about geometric-perceptual phenomena and formulating potential answers to these questions. Not only will it be concluded that topology is a suitable mathematical framework in which one can formulate relevant questions and potential answers with respect to perceptual phenomena such as the ML illusion, it will also be discussed that topology will not be replaced by other means of spatial representation consistent with the findings that indicate its contributions to our daily spatial behavior along with other means such as Euclidean geometry. In addition, the analysis will be discussed with respect to two relevant themes: 1) the implications of the proposed view in relation to Husserl’s phenomenology and 2) the effect of developmental stages and education that may change the involvement of topology in such perceptual responses over time.

A sample of Yukatek Maya children was tested on their capacity to attribute false beliefs to a variety of stimuli, both natural and non-natural. Children's capacity to correctly infer that humans have limited perceptual access, and are, therefore, not likely to know what is inside a container if the contents have been surreptitiously replaced, is shown to have significant consequences. Children who passed the test with the human stimulus showed a nuanced capacity to attribute similar or dissimilar knowledge to (...) other natural and non-natural entities, consistently with these entities' cultural representations. In contrast, those who failed the test with the human stimulus tended to attribute similar beliefs to all natural and non-natural entity stimuli. (shrink)

In this paper I argue that there is a viable simulationist account of emotion attribution. However, I also try to say something specific about the form that this account ought to take. I argue that someone who wants to give by a simulationist account of emotion attribution should focus on similarities between emotions and perceptual judgments.

Negative compatibility effects in the masked-prime paradigm are usually obtained when primes are masked effectively. With ineffective masks—and primes above the perceptual threshold—positive compatibility effects occur. We investigated whether this pattern reflects a causal relationship between conscious awareness and low-level motor control, or whether it reflects the fact that both are affected in the same way by changes in physical stimulus attributes. In a 5-session perceptual learning task, participants learned to consciously identify masked primes. However, they showed unaltered (...) NCEs that were not different from those produced by participants in a control group without equivalent perceptual learning. A control experiment demonstrated that no NCEs occur when prime identification is made possible by ineffective masking. The results suggest that perceptual awareness and low-level motor control are affected by the same factors, but are fundamentally independent of each other. (shrink)

This phenomenological research investigates how it is possible to determine the extent to which a chromatic colour appears white and black in order to use it to build a new Colour Rendering Index. We tested two methods of subjective evaluation; in the first, the perceptual presence of white (and black) in a colour alone was assessed on a unipolar intensity scale, independently for the two attributes. In the second method, evaluations of whiteness (and blackness) were conducted for colours presented (...) in a sequence ordered from the least to the greatest presence of the respective attribute. In both tests evaluations were made either by moving an arrow on a slider from left (minimum) to right (maximum) or by choosing a grey cylinder that matched the same degree of similarity to white (and black) as the test colour. In four experiments, 16 colours of 4 hues and 4 different shades were studied; in a fifth experiment, 48 colours, 12 for each quadrant of the colour wheel, were studied; finally, in another test, 10 greys were studied. In the first three experiments, the results were unexpected, as the evaluations of whiteness and blackness were complementary, adding up to 100%, while in the current NCS, 100% includes not only the evaluation of white and black but also that of chromaticness, therefore white and black are not complementary. In the fourth and fifth experiments, the sum of the evaluations of white and black was always less than 100%, in accordance with the present NCS. In the last experiment, the evaluations of white and black given independently to the 10 greys samples were complementary, confirming the bipolar nature of white-black continuum. Suggestions have been provided to resolve the discrepancy between the results of this research and the structure of the current NCS. (shrink)

High figure-ground contrast usually results in more positive evaluations of visual stimuli. This may either reflect that high figure-ground contrast per se is a desirable attribute or that this attribute facilitates fluent processing. In the latter case, the influence of high figure-ground contrast should be most pronounced under short exposure times, that is, under conditions where the facilitative influence on perceptual fluency is most pronounced. Supporting this hypothesis, ratings of the prettiness of visual stimuli increased with figure-ground contrast under (...) short exposure times (.3, 1, and 3 seconds, respectively). This positive influence of figure-ground contrast was eliminated under an exposure time of 10 seconds. We conclude that stimuli with high figure-ground contrast are more appealing because they are easier to process, not because high figure-ground contrast per se is a desirable attribute. We discuss this finding in the context of William James? notion that the fringe of consciousness includes vague contextual feelings at the periphery of the focus of attention and suggest that perceptual fluency is one of these feelings.

Visual modules can be viewed as expressions of a marked analytic attitude in the study of vision. In vision psychology, this attitude is accompanied by hypotheses that characterize how visual modules are thought to operate in perceptual processes. Our thesis here is that there are what we call “intrinsic reasons” for the presence of such hypotheses in a vision theory, that is, reasons of a deductive kind, which are imposed by the partiality of the basic terms in the definition (...) of a module, and by peculiar characteristics of those terms. Specifically, we discuss three hypotheses of functional attributes: successive stages in the action of modules, residual indeterminacy of their effects, and the role of prior constraints. For each of the three, we indicate its occurrence in perceptual psychology, explain corresponding intrinsic reasons, and illustrate such reasons with examples. (shrink)

We use a transmission chain method to establish how context and category salience influence the formation of novel stereotypes through cumulative cultural evolution. We created novel alien targets by combining features from three category dimensions—color, movement, and shape—thereby creating social targets that were individually unique but that also shared category membership with other aliens (e.g., two aliens might be the same color and shape but move differently). At the start of the transmission chains each alien was randomly assigned attributes that (...) described it (e.g., arrogant, caring, confident). Participants were given training on the alien‐attribute assignments and were then tested on their memory for these. The alien‐attribute assignments participants produced during test were used as the training materials for the next participant in the transmission chain. As information was repeatedly transmitted an increasingly simplified, learnable stereotype‐like structure emerged for targets who shared the same color, such that by the end of the chains targets who shared the same color were more likely to share the same attributes (a reanalysis of data from Martin et al., which we term Experiment 1). The apparent bias toward the formation of novel stereotypes around the color category dimension was also found for objects (Experiment 2). However, when the category dimension of color was made less salient, it no longer dominated the formation of novel stereotypes (Experiment 3). The current findings suggest that context and category salience influence category dimension salience, which in turn influences the cumulative cultural evolution of information. (shrink)

The purpose of this research is to highlight the relationship between green product attributes and consumer trust that influence consumers’ decision to purchase green products in the context of Pakistan. This study contributes to determining quantitatively how green product attributes such as physical, perceptual, and reflexive attributes influence consumers’ trust to purchase a green product and investigates the mediating role of green marketing. Data was collected from different industrial sectors through a survey questionnaire. We employed Structural Equation Modeling using (...) the SMART-PLS software to check the reliability and validity of the constructs, and to test the hypotheses. This study reveals variations in terms of shaping the sustainable consumers’ buying behavior by modifying product attributes and green marketing strategies that are in congruence with the proposed hypotheses of this study. In the end, the findings and interpretations of the results are given which can guide the managers to develop effective green marketing campaigns in reshaping the purchase intentions of consumers toward their green products.

This report concerns the fragmented visual percepts in a woman, TR, following a right entorhinal–perirhinal infarct. In a previous report, Weddell [Weddell, R. A. . A visual disorder producing highly selective deletion of recurring letters. Cortex, 41, 471–485] linked TR’s highly selective tendency to delete recurrent letters with her fragmented percepts. The conflation of same-identity form elements was attributed to anterior extrastriate damage, which reduced the amount of information sustainable in fully resolved visual percepts, and the present experimental investigation of (...) her subjective account of segment formation and resolution completes the story. She said that complex objects and long words first appeared as blurred regions, which sometimes included form elements. It is argued that figure-centred attentional mechanisms subdivided this blurred region into up to 3–4 parts. String length, lexical status , and background colour and/or luminance determined fragment length. Two rules described the fragment resolution sequence: largest segments usually resolved first, left-to-right resolution accounting for a few sequences. This resolution sequence occurred when stimuli were exposed too briefly for saccadic exploration, implicating endogenous attentional shifts. Experiment 4 confirmed TR’s assertion that spatial, orthographic, and phonological information were stored during the fragment resolution process. Moreover, TR exerted considerable voluntarily control over the fragment resolution sequence and some influence over fragment length. Finally, these findings were interpreted in terms of an extended version of a neural network model of vision largely derived from nonhuman primate studies. (shrink)
