Most contemporary theorists regard the traditional thesis that perception is essentially conscious as just another armchair edict to be abandoned in the wake of empirical discovery. Here I reconsider this dramatic departure from tradition. My aim is not to recapture our prelapsarian confidence that perception is inevitably conscious (though much I say might be recruited to that cause). Instead, I want to problematize the now ubiquitous belief in unconscious perception. The paper divides into two parts. Part One is more purely (...) philosophical. It explains how standard arguments for unconscious perception rely on contentious background assumptions concerning the relation between ordinary perception and the explanatory constructs of scientific psychology. Part Two, in contrast, offers detailed engagement with relevant empirical work. It exposes how, even setting aside the concerns identified in Part One, a dilemma confronts the believer in unconscious perception. This dilemma arises because ordinary perception is an individual-level state or occurrence, yet criteria sufficiently stringent to guarantee that a putatively perceptual state is unconscious vitiate the grounds for its attribution to the individual. The dilemma foments a hypothesis, namely that the conditions for genuine, individual-level perception are sufficient conditions for perceptual consciousness. The viability of this hypothesis should unnerve anyone who thinks unconscious perception is simply an empirical given. (shrink)

According to representationalism, phenomenal character supervenes on representational content. According to first-person reports, blindsighters have no phenomenal character in the scotoma, even though their abilities suggest that they have conscious visual representations in the scotoma. The traditional representationalist response is that the representations in the scotoma are either non-conscious or non-visual. Drawing on empirical work, I consider the interpretation that blindsighters are unable to represent—and thus lack the phenomenal character of—luminance in the scotoma. However, they maintain the capacity to represent (...) other visible properties in the scotoma, and thus retain the luminance-lacking phenomenal character of these properties. (shrink)

The most widely endorsed philosophical and scientific theories of consciousness assume that it contributes a single functional capacity to an organism’s information processing toolkit. However, conscious processes are a heterogeneous class of psychological phenomena supported by a variety of neurobiological mechanisms. This suggests a plurality of functional contributions of consciousness (FCCs), in the sense that conscious experience facilitates different functional capacities in different psychological domains. In this paper, I first develop a general methodological framework for isolating the psychological functions that (...) are associated with conscious experience. I then use this to show that the leading accounts—Global Workspace Theories, Higher Order Thought Theory and Information Integration Theory—all fail to acknowledge this functional pluralism, which limits their applicability as theories of consciousness.
