People believe that perception is reliable and that what they perceive reflects objective reality. On this view, we perceive a red circle because there is something out there that is a red circle. It is also commonly believed that perceptual reliability is threatened if what we see is allowed to be influenced by what we know or expect. I argue that although human perception is often highly consistent and stable, it is difficult to evaluate its reliability because when it comes (...) to perception, it is unclear how one could establish a fact of the matter. An alternative to thinking of perception as being in the business of truth, is thinking of it as being in the business of transducing sensory energy into a form useful for guiding adaptive behavior. On this position, perception ought to be richly influenced by some types of knowledge insofar as this knowledge can aid in the construction of useful representations from sensory input. (shrink)

In his recent work, T.M. Scanlon has argued for a relationship based theory of blame. For Scanlon moral blame involves the modification of the moral relationship. He holds that this relationship obtains among all rational beings. George Sher has recently argued that Scanlon’s theory cannot account for blame between strangers. Following Sher, I argue that Scanlon’s account of blame precludes complete strangers and that his conception of the moral relationship is fundamentally inconsistent with his theory of blame generally. I contend (...) that Scanlon’s moral relationship, in itself, precludes the possibility of blaming on his account. (shrink)

Orange heart shapes are commonly perceived as slightly reddish, which is an example of the memory color effect (MCE). Given that the MCE is a modulation of visual memories of typical colors of familiar objects, it can be considered to be a top-down effect. Whether cognitive penetration can explain MCEs has been actively debated since Macpherson argued that the belief that hearts are red alters orange perception. This paper aims to provide a credible explanation of the MCE that is consistent (...) with scientific studies. I first prove that Macpherson’s theory is not properly supported by the psychological evidence that she provides. I also show that her model contradicts a report on the neural correlate of the MCE. Next, I examine color constancy, which enables the perception of colors as constant under various illuminations, as a possible noncognitive principle for the MCE. The relationship between them, however, is not well established. Using statistical analyses of scenes around us, Purves suggests that perception is determined by the most frequent percepts. I argue that Purves’ view better explains the noncognitive aspects of visual memory and is consistent with the finding of the neural correlate of the MCE. (shrink)

Albert Newen and Petra Vetter argue that neurophysiological considerations and psychophysical studies provide striking evidence for cognitive penetration. This commentary focuses mainly on the neurophysiological considerations, which have thus far remained largely absent in the philosophical debate concerning cognitive penetration, and on the cognitive penetration of perceptual experiences, which is the form of cognitive penetration philosophers have debated about the most. It is argued that Newen and Vetter's evidence for cognitive penetration is unpersuasive because they do not sufficiently scrutinize the (...) details of the empirical studies they make use of-the details of the empirical studies are crucial also when the studies are used in philosophical debates. The previous does not mean that cognitive penetration could not occur. Quite the contrary, details of the feedback connections to the visual perceptual module and one of the candidates presented by Newen and Vetter suggest that cognitive penetration can occur in rare cases.

I argue for sensory pluralism. This is the view that there are many forms of sensory interaction and unity, and no single category that classifies them all. In other words, sensory interactions do not form a single natural kind. This view suggests that how we classify sensory systems (and the experiences they generate) partly depends on our explanatory purposes. I begin with a detailed discussion of the issue as it arises for our understanding of thermal perception, followed by a general (...) account and defense of sensory pluralism. (shrink)

This paper develops a theory of perception that reconciles representationalism and relationalism by relying on pragmatist ideas. I call it the pragmatic view of perception. I argue that fully reconciling representationalism and relationalism requires, first, providing a theory in which how we perceive the world involves representations; second, preserving the idea that perception is constitutively shaped by its objects; and third, offering a direct realist account of perception. This constitutes what I call the Hybrid Triad. I discuss how Charles Peirce’s (...) theory of perception can provide a framework for such a view and I devote the rest of the paper to developing my own pragmatic and Peircean theory of perception. In particular, I argue that considering perception as a continuous temporal process, which essentially involves interaction with the environment, allows us to do justice to the Hybrid Triad. I motivate this view by discussing how a pragmatic theory of perception would deal with issues such as the distinction between veridical and non-veridical experiences and the nature of perceptual objects.

I elaborate on Pylyshyn's definition of the cognitive impenetrability (CI) of early vision, and draw on the role of concepts in perceptual processing, which links the problem of the CI or cognitive penetrability (CP) of early vision with the problem of the nonconceptual content (NCC) of perception. I explain, first, the sense in which the content of early vision is CI and I argue that if some content is CI, it is conceptually encapsulated, that is, it is NCC. Then, I (...) examine the definitions of NCC and argue that they lead to the view that the NCC of perception is retrieved in a stage of visual processing that is CI. Thus, the CI of a state and content is a sufficient and necessary condition for the state and its content to be purely NCC, the CI?≡?NCC thesis. Since early vision is CI, the purely NCC of perception is formed in early vision. I defend the CI?≡?NCC thesis by arguing against objections raised against both the sufficient and the necessary part of the thesis. (shrink)

Moral perception is typically understood as moral properties perception, i.e., the perceptual registration of moral properties such as wrongness or dignity. In this article, I defend a view of moral perception as a process that involves imaginative apprehension of reality. It is meant as an adjustment to the dominant view of moral perception as moral properties perception and as an addition to existing Murdochian approaches to moral perception. The view I present here builds on Iris Murdoch’s moral psychology and holds (...) that moral perception is an imaginative exploration of the particularity of concrete objects of moral reality (e.g., persons, situations, and events), rather than a registration of moral properties. I argue that such imaginative apprehension includes direct and reflective uses of imagination and that this process grounds experiential moral knowledge that serves the ultimate role of moral perception: getting a better grip on concrete objects of moral reality.

This paper develops Kendall Walton's account of pictorial experience. Walton argues that the key feature of that experience is that it is imaginatively-penetrated experience. I argue that this idea, as put forward by Walton, has various shortcomings. After discussing these limitations, I suggest, on the basis of a more general phenomenon of cognitive penetration, a refinement of Walton's account. I then show how the revised account explains various features of pictorial experience. Specifically, I show that, given the manner in which (...) imaginings influence perceptual experience, Walton can dispense with the thesis that pictorial experience is twofold. (shrink)

The question of how we actually arrive at our knowledge of others’ mental lives is lively debated, and some philosophers defend the idea that mentality is sometimes accessible to perception. In this paper, a distinction is introduced between “mind awareness” and “mental state awareness,” and it is argued that the former at least sometimes belongs to perceptual, rather than cognitive, processing.

This paper proposes a set of criteria for an appropriate experiment on the issue of the theory ladenness of perception. These criteria are used to select a number of experiments that use: belief-based ambiguous figures, fragmented figures, or memory color. Crucially, the data in experiments of this type are based on the participant’s qualitative visual experience. Across many different types of experimental designs, different types of stimuli, and different types of belief manipulation, these experiments show the impact of belief/theory on (...) visual perception. Using an ecological validity argument, I conclude that attention-based interpretations of these findings are not successful because the relevant epistemological issues only require that we examine final perception, in the sense of visual awareness of the everyday world. Finally, I argue that the epistemological consequences of theory-ladenness can be reduced by using a top-down/bottom-up theoretical framework and by adopting appropriate methodological procedures to data derived from individual observations.

Empirical research suggests that motive states modulate perception affecting perceptual processing either directly, or indirectly through the modulation of spatial attention. The affective modulation of perception occurs at various latencies, some of which fall within late vision, that is, after 150 ms. poststimulus. Earlier effects enhance the C1 and P1 ERP components in early vision, the former enhancement being the result of direct emotive effects on perceptual processing, and the latter being the result of indirect effects of emotional stimuli on (...) perceptual processing that automatically capture exogenous attention. Other research suggests that emotional stimuli do not capture attention automatically but attentional capture is conditioned on the context. Since context dependent effects are first registered with the elicitation of N1 ERP component about 170 ms. poststimulus, emotional stimuli affect late vision. However, the early affective modulation of early vision by emotive states threatens the cognitive impenetrability of early vision since emotive states are associated with learning and past experiences. I argue that the emotive modulation of early vision does not entail the cognitive penetrability of early vision. First, the early indirect affective modulation of P1 is akin to the effects of spatial pre-cueing by non-emotive cues and these preparatory effects do not signify the cognitive impenetrability of early vision. Second, because the direct modulation of C1 signifies an initial, involuntary appraisal of threat in the incoming stimulus that precedes any cognitive states. (shrink)
