  1. Contents of Unconscious Color Perception.Błażej Skrzypulec - 2022 - Review of Philosophy and Psychology 13 (3):665-681.
    In the contemporary discussions concerning unconscious perception it is not uncommon to postulate that content and phenomenal character are ‘orthogonal’, i.e., there is no type of content which is essentially conscious, but instead, every representational content can be either conscious or not. Furthermore, this is not merely treated as a thesis justified by theoretical investigations, but as supported by empirical considerations concerning the actual functioning of the human cognition. In this paper, I address unconscious color perception and argue for a (...)

  2. Is Blindsight Possible Under Signal Detection Theory? Comment on Phillips (2021).Mathias Michel & Hakwan Lau - 2021 - Psychological Review 128 (3):585-591.
    Phillips argues that blindsight is due to response criterion artefacts under degraded conscious vision. His view provides alternative explanations for some studies, but may not work well when one considers several key findings in conjunction. Empirically, not all criterion effects are decidedly non-perceptual. Awareness is not completely abolished for some stimuli, in some patients. But in other cases, it was clearly impaired relative to the corresponding visual sensitivity. This relative dissociation is what makes blindsight so important and interesting.

  3. The Role of Experience in Demonstrative Thought.Michael Barkasi - 2019 - Mind and Language 34 (5):648-666.
    Attention plays a role in demonstrative thought: It sets the targets. Visual experience also plays a role. I argue here that it makes visual information available for use in the voluntary control of focal attention. To do so I use both introspection and neurophysiological evidence from projections between areas of attentional control and neural correlates of consciousness. Campbell and Smithies also identify roles for experience, but they further argue that only experience can play those roles. In contrast, I argue that (...)

  4. Naïve Realism and Unconscious Perception: A Reply to Berger and Nanay.Alfonso Anaya & Sam Clarke - 2017 - Analysis 77 (2):267-273.
    In a recent paper, Berger and Nanay consider, and reject, three ways of addressing the phenomenon of unconscious perception within a naïve realist framework. Since these three approaches seem to exhaust the options open to naïve realists, and since there is said to be excellent evidence that perception of the same fundamental kind can occur, both consciously and unconsciously, this is seen to present a problem for the view. We take this opportunity to show that all three approaches considered remain (...)

  5. Type 2 Blindsight and the Nature of Visual Experience.Berit Brogaard - 2015 - Consciousness and Cognition 32:92-103.
    Blindsight is a kind of residual vision found in people with lesions to V1. Subjects with blindsight typically report no visual awareness, but they are nonetheless able to make above-chance guesses about the shape, location, color and movement of visual stimuli presented to them in their blind field. A different kind of blindsight, sometimes called type 2 blindsight, is a kind of residual vision found in patients with V1 lesions in the presence of some residual awareness. Type 2 blindsight differs (...)

  6. Are There Unconscious Perceptual Processes?Berit Brogaard - 2011 - Consciousness and Cognition 20 (2):449-63.
    Blindsight and vision for action seem to be exemplars of unconscious visual processes. However, researchers have recently argued that blindsight is not really a kind of uncon- scious vision but is rather severely degraded conscious vision. Morten Overgaard and col- leagues have recently developed new methods for measuring the visibility of visual stimuli. Studies using these methods show that reported clarity of visual stimuli correlates with accuracy in both normal individuals and blindsight patients. Vision for action has also come under (...)

  7. Blindsight in Monkeys: Lost and (Perhaps) Found.Sean Allen-Hermanson - 2010 - Journal of Consciousness Studies 17 (1-2): 47-71.
    Stoerig and Cowey’s work is widely regarded as showing that monkeys with lesions in the primary visual cortex have blindsight. However, Mole and Kelly persuasively argue that the experimental results are compatible with an alternative hypothesis positing only a deficit in attention and perceptual working memory. I describe a revised procedure which can distinguish these hypotheses, and offer reasons for thinking that the blindsight hypothesis provides a superior explanation. The study of blindsight might contribute towards a general investigation into animal (...)

  8. Insects and the Problem of Simple Minds: Are Bees Natural Zombies?Sean Allen-Hermanson - 2008 - Journal of Philosophy 105 (8): 389-415.
    This paper explores the idea that many “simple minded” invertebrates are “natural zombies” in that they utilize their senses in intelligent ways, but without phenomenal awareness. The discussion considers how “first-order” representationalist theories of consciousness meet the explanatory challenge posed by blindsight. It would be an advantage of first-order representationalism, over higher-order versions, if it does not rule out consciousness in most non-human animals. However, it is argued that a first-order representationalism which adequately accounts for blindsight also implies that most (...)

  9. A Re-Evaluation of Blindsight and the Role of Striate Cortex (V1) in Visual Awareness.Juha Silvanto - 2008 - Neuropsychologia.
    Some patients with a lesion to the striate cortex (V1), when assessed through forced-choice paradigms, are able to detect stimuli presented in the blind field, despite reporting a complete lack of visual experience. This phenomenon, known as blindsight, strongly implicates V1 in visual awareness. However, the view that V1 is indispensable for conscious visual perception is challenged by a recent finding that the blindsight subject GY can be aware of visual qualia in his blind field, implying that V1may not be (...)

  10. On Schellenberg’s The Unity of Perception.Ayoob Shahmoradi - manuscript
    My general worry is that Schellenberg’s arguments against naive realism, generalism, and Russellian representationalism do not seem to be successful. Thus her attempt at ruling these views out fails. Her main arguments rely on a shared premise whose plausibility, in the absence of an appropriate theory of particulars, is hard to assess (§2.1). Apart from that, these arguments rely on an under-specified notion of constitution; there seems to be no sense of the term that makes all the premises of her (...)
