Theories of philosophy of perception are too simplifying. Direct realism and representationalism, for example, are philosophical theories of perception about the nature of the perceived object and its location. It is common sense to say that we directly perceive, through our senses, physical objects together with their properties. However, if perceptual experience is representational, it only appears that we directly perceive the represented physical objects. Despite psychological studies concerning the role of memory in perception, what these two philosophical theories do (...) not explicate are the continuity of the external describable object and the role of memory in perceiving the continuity, difference, break or ending. Using empirical evidence of particular cases and the hypothetico-deductive model, this research article analyses how one is able to perceive the continuity of same things. The early stages of perceptual process are not sufficient for the perception of continuity. Empirical evidence of memory disorders shows that persons with a memory disorder do not perceive the same thing or the familiar place they previously saw and now experience or remember what they are thinking about, even if the object, the place or the person has remained the same. I will argue that the perception of continuity requires memory. In fact, observation indicates how the memory runs at the same time, when the object is seen over time. This fact implies the memory system’s essential role for perceiving the continuity of the same things. (shrink)

Purely parallel neural networks can model object recognition in brief displays – the same conditions under which illusory conjunctions have been demonstrated empirically. Correcting errors of illusory conjunction is the “tag-assignment” problem for a purely parallel processor: the problem of assigning a spatial tag to nonspatial features, feature combinations, and objects. This problem must be solved to model human object recognition over a longer time scale. Our model simulates both the parallel processes that may underlie illusory conjunctions and the serial (...) processes that may solve the tag-assignment problem in normal perception. One component of the model extracts pooled features and another provides attentional tags that correct illusory conjunctions. Our approach addresses two questions: How can objects be identified from simultaneously attended features in a parallel, distributed representation? How can the spatial selectional requirements of such an attentional process be met by a separation of pathways for spatial and nonspatial processing? Our analysis of these questions yields a neurally plausible simulation of tag assignment based on synchronizing feature processing activity in a spatial focus of attention. (shrink)

Two experiments show that action alters the shape categories formed by 2-year-olds. Experiment 1 shows that moving an object horizontally (or vertically) defines the horizontal (or vertical) axis as the main axis of elongation and systematically changes the range of shapes seen as similar. Experiment 2 shows that moving an object symmetrically (or asymmetrically) also alters shape categories. Previous work has shown marked developmental changes in object recognition between 1 and 3 years of age. These results suggest a role for (...) action in this developmental process. (shrink)

Classical antiquity provides not just the storehouse metaphor, which postdates Plato, but also parts of the correspondence metaphor. In the fifth century B.C., Thucydides (1.22) considered the role of gist and accuracy in writing history, and Aristotle (Poetics1451b, 1460b 8–11) offered an explanation. Finally, the Greek for truth (alêtheia) means “that which is not forgotten.”.

For many years, the Shroud of Turin has been famous for images of a body and face which many believe were formed during The Resurrection. More recently, however, claims have been made that the Shroud also contains evidence of other objects, and these claims have been used to support the view that the Shroud is the burial cloth of Jesus. However, these claims are based on marks that are barely visible and the psychological processes known to be involved in perceiving (...) objects under data-limited conditions have been largely ignored. Here, we consider these processes and assess the claims that objects can be seen on the Shroud. We conclude that the viewing conditions provided by images of the Shroud are likely to lead to the illusory perception of objects, and knowing the psychological processes underlying these perceptions is crucial for accurately determining the provenance of the Shroud and other material artefacts.

This article examines the structure and processing of editorial cartoons appropriating Joe Rosenthal's famous Iwo Jima photograph in view of the theory of conceptual blending (Fauconnier & Turner, 2002 Fauconnier, G. and Turner, M. 2002. The way we think: Conceptual blending and the mind's hidden complexities, New York,, NY: Basic Books. [Google Scholar]). The main claim argued is that Blending theory accounts for complex processes of meaning constructing provoked by editorial cartoons that invoke several conceptual domains to define and evaluate (...) their topic, Iwo Jima cartoons being cases in point. The second section introduces the relevant aspects of Blending theory: mental spaces and types of blending networks. The third section addresses the Iwo Jima image as one particular input space; a moral criterion to which the selected sociopolitical topic of the cartoon is compared and judged. The fourth section isolates four types of graphic operations blending the Iwo Jima image with topical entities. The fifth section demonstrates how various kinds of blends give rise to either positive or negative evaluations. The final section argues that the study's scope of application extends to any kind of multi-domain cartoon, not just those addressed in this article. (shrink)

This article considers how people judge the identity of objects (e.g., how people decide that a description of an object at one time, t₀, belongs to the same object as a description of it at another time, t₁). The authors propose a causal continuer model for these judgments, based on an earlier theory by Nozick (1981). According to this model, the 2 descriptions belong to the same object if (a) the object at t₁ is among those that are causally close (...) enough to be genuine continuers of the original and (b) it is the closest of these close-enough contenders. A quantitative version of the model makes accurate predictions about judgments of which a pair of objects is identical to an original (Experiments 1 and 2). The model makes correct qualitative predictions about identity across radical disassembly (Experiment 1) as well as more ordinary transformations (Experiments 2 and 3). (shrink)

We think of the world around us as divided into physical objects like toasters and daisies, rather than solely as a smear of properties like yellow and smooth. How do we single out these objects? One theory of object concepts uses part‐of relations and relations of connectedness. According to this proposal, an object is a connected spatial item of maximal extent: Any other connected item that overlaps (i.e., shares a part with) the object must be a part of that object. (...) This article reports four experiments that test this proposal. Participants see descriptions or diagrams of spatial items that vary across trials in their relative positions. In separate experiments, participants decide whether the items are physical objects, whether they are wholes, or how many objects are present. All experiments find support for connectedness as a contributor to object status, but they find little support for maximality. The results suggest that maximality is not a necessary feature of wholes or of objects. (shrink)

The effect of uniform lighting on face identity processing is little understood, despite its potential influence on our ability to recognize faces. Here, we investigated how changes in uniform lighting level affected face identification performance during face memory tests. Observers were tasked with learning a series of faces, followed by a memory test where observers judged whether the faces presented were studied before or novel. Face stimuli were presented under uniform bright or dim illuminations, and lighting across the face learning (...) and the memory test sessions could be the same or different. This led to four experimental conditions: Bright/Dim ; Bright/Bright; Dim/Bright; and Dim/Dim. Our results revealed that incongruent lighting levels across sessions significantly reduced sensitivity to faces and introduced conservative biases compared to congruent lighting levels. No significant differences in performance were detected between the congruent lighting conditions and between the incongruent lighting conditions. Thus, incongruent lighting deteriorated performance in face identification. These findings implied that the level of uniform lighting should be considered in an illumination-specific face representation and potential applications such as eyewitness testimony. (shrink)

It is common to think of warfare as a setting in which emotion can lead combatants to engage in unethical behavior. On this view, it is natural to conceptualize the aim of military ethics training as quelling the influence of emotion in combat in order to reduce the risk that military personnel are vulnerable to its influence. Recent research, however, indicates that what is called “emotion processing” is connected in important ways with moral judgment and behavior. In this view, acting (...) ethically is not simply a matter of subordinating emotion to reason, but of responding with appropriate rather than inappropriate emotion. In this respect, such research challenges the powerful “rationalist” account of moral judgment and behavior. More fundamentally, it calls into question the distinction between reason and emotion as a way to understand our moral sensibilities. This article describes this research and discusses work on naturalistic decision-making and neuroscience that provide support for its insights. It then suggests ways in which such research is consistent with Aristotelian notions of character and virtue. Finally, it identifies ways in which some military training implicitly draws on lessons from this body of research, and suggests how it might do so more deliberately. (shrink)

Fodor has argued that observation is theory neutral, since the perceptual systems are modular, that is, they are domain‐specific, encapsulated, mandatory, fast, hard‐wired in the organism, and have a fixed neural architecture. Churchland attacks the theoretical neutrality of observation on the grounds that (a) the abundant top‐down pathways in the brain suggest the cognitive penetration of perception and (b) perceptual learning can change in the wiring of the perceptual systems. In this paper I introduce a distinction between sensation, perception, and (...) observation and I argue that although Churchland is right that observation involves top‐down processes, there is also a substantial amount of information in perception which is theory‐neutral. I argue that perceptual learning does not threaten the cognitive impenetrability of perception, and that the neuropsychological research does not provide evidence in favor of the top‐down character of perception. Finally, I discuss the possibility of an off‐line cognitive penetrability of perception. (shrink)

We represent shape in both sight and touch, but how do these abilities relate to one another? This issue has been discussed in the context of Molyneux's question of whether someone born blind could, upon being granted sight, identify shapes visually. Some have suggested that we might look to real‐world cases of sight restoration to illuminate the relation between visual and tactual shape representations. Here, I argue that newly sighted perceivers should not be relied on in this way because they (...) are unlikely to form the kinds of shape representations responsible for cross‐modal recognition in normally sighted perceivers. I then argue that the available evidence makes a compelling case for the type identity view, on which the visual and tactual representations responsible for cross‐modal recognition are type‐identical.

This article examines the anatomy and circuitry of skills that, like reading, calculating, recognizing, or remembering, are common abilities of humans. While the anatomical areas active are unique to each skill there are features common to all tasks. For example, all skills produce activation of a small number of widely separated neural areas that appear necessary to perform the task. These neural areas relate to internal codes that may not be observed by any external behavior nor be reportable by the (...) performer. There is considerable plasticity to the performance of skills. Task components can be given priority through attention, which serves to increase activation of the relevant brain areas. Attention can also cause reactivation of sensory areas driven by input, but usually only after a delay. The threshold for activation for any area may be temporarily reduced by prior activation . Skill components requiring attention tend to cause interference resulting in the dual tasks effects and unified focus of attention described in many cognitive studies. Practice may change the size or number of brain areas involved and alter the pathways used by the skill. By combining cognitive and anatomical analyses, a more general picture of the nature of skill emerges. (shrink)
