    A Signal-Detection-Theory Representation of Normal and Hallucinatory Perception.Igor Dolgov & Michael K. McBeath - 2005 - Behavioral and Brain Sciences 28 (6):761-762.
    Collerton et al.'s Perception and Attention Deficit model argues that all recurrent complex visual hallucinations result from maladaptive, deficient sensory and attentional processing. We outline a constructivist-based representation of perception using signal detection theory, in which hallucinations are modeled as false alarms when confirmational perceptual information is lacking. This representation allows for some individuals to have RCVH due to a criterion shift associated with attentional proficiency that results in an increased awareness of the environment.

  5. Is Vision Continuous with Cognition? The Case for Cognitive Impenetrability of Visual Perception.Zenon W. Pylyshyn - 1999 - Behavioral and Brain Sciences 22 (3):341-365.
    Although the study of visual perception has made more progress in the past 40 years than any other area of cognitive science, there remain major disagreements as to how closely vision is tied to general cognition. This paper sets out some of the arguments for both sides and defends the position that an important part of visual perception, which may be called early vision or just vision, is prohibited from accessing relevant expectations, knowledge and utilities - in other words it (...)

    Signal Detection Theory, the Exclusion Failure Paradigm and Weak Consciousness—Evidence for the Access/Phenomenal Distinction?Elizabeth Irvine - 2009 - Consciousness and Cognition 18 (2):551-560.
    Block [Block, N. . Two neural correlates of consciousness. Trends in Cognitive Science, 9, 46–52] and Snodgrass claim that a signal detection theory analysis of qualitative difference paradigms, in particular the exclusion failure paradigm, reveals cases of phenomenal consciousness without access consciousness. This claim is unwarranted on several grounds. First, partial cognitive access rather than a total lack of cognitive access can account for exclusion failure results. Second, Snodgrass’s Objective Threshold/Strategic model of perception relies on a problematic ‘enable’ approach (...)

    Is Vision Continuous with Cognition?Zenon W. Pylyshyn - 2000 - Behavioral and Brain Sciences 22 (3):341-365.
    Although the study of visual perception has made more progress in the past 40 years than any other area of cognitive science, there remain major disagreements as to how closely vision is tied to cognition. This target article sets out some of the arguments for both sides (arguments from computer vision, neuroscience, psychophysics, perceptual learning, and other areas of vision science) and defends the position that an important part of visual perception, corresponding to what some people have called early vision, (...)

    Consciousness and Criterion: On Block's Case for Unconscious Seeing.Ian Phillips - 2016 - Philosophy and Phenomenological Research 93 (2):419-451.
    Block () highlights two experimental studies of neglect patients which, he contends, provide ‘dramatic evidence’ for unconscious seeing. In Block's hands this is the highly non-trivial thesis that seeing of the same fundamental kind as ordinary conscious seeing can occur outside of phenomenal consciousness. Block's case for it provides an excellent opportunity to consider a large body of research on clinical syndromes widely held to evidence unconscious perception. I begin by considering in detail the two studies of neglect to which (...)

    Interactive Perception for Amplification of Intended Behavior in Complex Noisy Environments.Yasser Mohammad & Toyoaki Nishida - 2009 - AI and Society 23 (2):167-186.
    The detection of a human’s intended behavior is one of the most important skills that a social robot should have in order to become acceptable as a part of human society, because humans are used to understand the actions of other humans in a goal-directed manner and they will expect the social robot to behave similarly. A breakthrough in this area can advance several research branches related to social intelligence such as learning by imitation and mutual adaptation. To achieve (...)

  25. Subjective Discriminability of Invisibility: A Framework for Distinguishing Perceptual and Attentional Failures of Awareness.Ryota Kanai, Vincent Walsh & Chia-Huei Tseng - 2010 - Consciousness and Cognition 19 (4):1045-1057.
    Conscious visual perception can fail in many circumstances. However, little is known about the causes and processes leading to failures of visual awareness. In this study, we introduce a new signal detection measure termed subjective discriminability of invisibility that allows one to distinguish between subjective blindness due to reduction of sensory signals or to lack of attentional access to sensory signals. The SDI is computed based upon subjective confidence in reporting the absence of a target . Using this new (...)

    Brief Body-Scan Meditation Practice Improves Somatosensory Perceptual Decision Making.Laura Mirams, Ellen Poliakoff, Richard J. Brown & Donna M. Lloyd - 2013 - Consciousness and Cognition 22 (1):348-359.
    We have previously found that attention to internal somatic sensations during a heart beat perception task increases the misperception of external touch on a somatic signal detection task , during which healthy participants erroneously report feeling near-threshold vibrations presented to their fingertip in the absence of a stimulus. However, it has been suggested that mindful interoceptive attention should result in more accurate somatic perception, due to its non-evaluative and controlled nature. To investigate this possibility, 62 participants completed the SSDT (...)

  27. A Higher Order Bayesian Decision Theory of Consciousness.Hakwan Lau - 2008 - In Rahul Banerjee & B. K. Chakrabarti (eds.), Models of Brain and Mind: Physical, Computational, and Psychological Approaches. Elsevier.
    It is usually taken as given that consciousness involves superior or more elaborate forms of information processing. Contemporary models equate consciousness with global processing, system complexity, or depth or stability of computation. This is in stark contrast with the powerful philosophical intuition that being conscious is more than just having the ability to compute. I argue that it is also incompatible with current empirical findings. I present a model that is free from the strong assumption that consciousness predicts superior performance. (...)

  28. Conscious Access to Fear-Relevant Information is Mediated by Threshold.Remigiusz Szczepanowski - 2011 - Polish Psychological Bulletin 42 (2):56-64.
    Conscious access to fear-relevant information is mediated by threshold The present report proposed a model of access consciousness to fear-relevant information according to which there is a threshold for emotional perception beyond that the subject makes hits with no false alarm. The model was examined by having the participants performed a confidence-ratings masking task with fearful faces. Measures of the thresholds for conscious access were taken by looking at the receiver operating characteristics curves generated from a three-state low- and high-threshold (...)

  29. Preferential Access to Emotion Under Attentional Blink: Evidence for Threshold Phenomenon.Lewis O. Harvey, Zhao Fan, Jakub Traczyk & Remigiusz Szczepanowski - 2015 - Polish Psychological Bulletin 46 (1):127-132.
    The present study provides evidence that the activation strength produced by emotional stimuli must pass a threshold level in order to be consciously perceived, contrary to the assumption of continuous quality of representation. An analysis of receiver operating characteristics for attentional blink performance was used to distinguish between two models of emotion perception by inspecting two different ROC’s shapes. Across all conditions, the results showed that performance in the attentional blink task was better described by the two-limbs ROC predicted by (...)

    Split-Brain Reveals Separate but Equal Self-Recognition in the Two Cerebral Hemispheres.Lucina Q. Uddin, Jan Rayman & Eran Zaidel - 2005 - Consciousness and Cognition 14 (3):633-640.
    To assess the ability of the disconnected cerebral hemispheres to recognize images of the self, a split-brain patient was tested using morphed self-face images presented to one visual hemifield at a time while making “self/other” judgments. The performance of the right and left hemispheres of this patient as assessed by a signal detection method was not significantly different, though a measure of bias did reveal hemispheric differences. The right and left hemispheres of this patient independently and equally possessed the (...)

    The Anomaly Called Psi: Recent Research and Criticism.K. Ramakrishna Rao & John R. Palmer - 1987 - Behavioral and Brain Sciences 10 (4):539-51.
    Over the past hundred years, a number of scientific investigators claim to have adduced experimental evidence for phenomena information” seems to behave like a weak signal that has to compete for the information-processing resources of the organism, a reduction of ongoing sensorimotor activity may facilitate ESP detection. Such a meaningful convergence of results suggests that psi phenomena may represent a unitary, coherent process whose nature and compatibility with current physical theory have yet to be determined. The theoretical implications and (...)
