Showing papers in "Consciousness and Cognition in 1998"


Journal ArticleDOI
TL;DR: The authors presented and discussed transcripts of some 270 explanations subjects provided subsequently for recognition memory decisions that had been associated with remember, know, or guess responses at the time the recognition decisions were made.

321 citations


Journal ArticleDOI
TL;DR: The results point to schizophrenia and related disorders as a paradigmatic alteration of a "Who?" system for self-consciousness.

298 citations


Journal ArticleDOI
TL;DR: It is concluded that action can be controlled by a sensory system which is specialized for on-line processing of relevant goal characteristics, and the performance obtained suggests that short-lived motor representations may rather be considered as real "presentation" of the action world, which share its metric properties.

217 citations


Journal ArticleDOI
TL;DR: Results indicate that only in the case of external raters' estimates do negative emotions outweigh the positive ones; but in the cases of self-ratings (i.e., those made by the dreamer himself/herself), the ratio was balanced.

140 citations


Journal ArticleDOI
TL;DR: Results are consistent with the assumption that subconscious threat detection can lead to misrepresentations of stimulus significance and that pathological anxiety is characterized by a hyperactive preattentive alarm system that is insufficiently controlled by higher cognitive processes.

89 citations


Journal ArticleDOI
TL;DR: The backward referral hypothesis, as formulated by Libet, should not be retained and results of coupling peripheral and cortical stimuli are explained by a latency after the cortical Minimum Train Duration, having roughly the same duration as the latency for supraliminal skin stimuli.

84 citations


Journal ArticleDOI
TL;DR: An attempt is made at finding an explanation of neglect and the links between the mechanisms of space representation and consciousness through the study of the changes induced by unilateral brain lesions in the characteristics of space-coding neurons.

78 citations


Journal ArticleDOI
TL;DR: The results explain why patients with blindsight are apparently more often "aware" of moving stimuli than of static stimuli, and imply that blindsight is unlike normal vision near threshold, and that pattern- and motion-detection in blindsight may depend on different sets of neural mechanisms during yes-no and forced-choice tests.

76 citations


Journal ArticleDOI
TL;DR: Results are inconsistent with general predictions made by the nonspecific activation hypothesis, but not the affective primacy or perceptual fluency hypotheses which were discussed in terms of cognitive neuroscience research.

71 citations


Journal ArticleDOI
TL;DR: It is assumed that the "near-the-threshold" depolarized state of neurons in the thalamus and cerebral cortex is a necessary condition for perceptual processes and consciousness, such as occurs during waking and in an altered form during rapid eye movement sleep.

Journal ArticleDOI
TL;DR: The results showed that, relative to the control subjects, DF's grasping movements produced normal peak velocity-distance scaling-when she reached for blocks which varied in depth or pointed to LED targets which were presented at different distances in depth, although her verbal estimates of object distance were poorly scaled, although they improved slightly under the binocular conditions.

Journal ArticleDOI
TL;DR: Assessment of visual form agnosic patient DF, whose lesion mainly affects the ventral stream, on a prehension task requiring allocentric spatial coding, finds her unable to adjust her grip aperture or her hand orientation in the three-hole task, consistent with the idea that allocentric processing of spatial information requires a functioning ventrals stream.

Journal ArticleDOI
TL;DR: It is suggested that much of the symptomology of left neglect can be interpreted as a disconnection between brain mechanisms that are relatively specialized for local (detail) visual processing and global (panoramic) processing, which has consequences for how perceptual and representational content enters into awareness.

Journal ArticleDOI
TL;DR: While sleep-onset reports can include all features of rapid eye movement (REM) dream reports, the number of such features is markedly reduced at sleep onset, suggesting that this mentation is a greatly diminished version of REM dreaming.


Journal ArticleDOI
TL;DR: Visual word-form priming was linked to a brain potential recorded from the scalp over the occipital lobe about 450 ms after word onset that differed from another potential previously associated with recollection, suggesting that distinct operations associated with these two types of memory can be monitored at the precise time that they occur in the human brain.

Journal ArticleDOI
TL;DR: It is argued that the authors' conscious visual experience of the world arises in the cortical visual system beyond V1, and much of the evidence suggests that the McCollough effect depends on neural mechanisms that are located early in the cortex visual pathways, probably in V1.

Journal ArticleDOI
TL;DR: Word-identification priming may depend on awareness of word identity at the time of study, and was reduced for ignored relative to attended words and after color naming relative to emotional valence rating.

Journal ArticleDOI
TL;DR: Experimental research of memory function in DID focuses on between-identity transfer of newly learned neutral material and shows that the apparent amnestic asymmetry for explicit information was substantiated in the laboratory, although at least some leakage was present between the apparentlyAmnestic identities.

Journal ArticleDOI
TL;DR: It is proposed that an immediate recognition mechanism belongs to the class of mental processes which are grouped under the name of intuition, that is, the processes by which situations or people's intentions are immediately understood, without conscious reasoning.

Journal ArticleDOI
TL;DR: Whether the process of making a spatially based decision is critical in forcing subjects to use the information in the cognitive system for spatial tasks is inquired, indicating that choice can be handled within the context-insensitive sensorimotor system.


Journal ArticleDOI
TL;DR: It is suggested that, in the visuomotor domain, information on the contralateral side is processed minimally, if at all, in patients with hemispatial neglect.


Journal ArticleDOI
TL;DR: It is suggested that demonstration of intact residual processes rather than the operation of covert processes, where proficient performance is accompanied by a denial of phenomenal awareness, reveal the possible covert use of chromatic differences.

Journal ArticleDOI
TL;DR: An exploration is given of neural network features now being uncovered in cortical processing which begins to go a little way to help bridge the "Explanatory Gap" between phenomenal consciousness and correlated brain activity.

Journal ArticleDOI
TL;DR: The results show that reaction times to seen targets in the normal hemifield of monkeys are influenced by the presentation of "unseen" target in the anopic hem ifield, as in some patients with cortically blind visual field defects.

Journal ArticleDOI
TL;DR: Results are consistent with typing and grammatical judgment tests tapping independent mechanisms and indicate that implicit learning may consist of many different forms of learning rather than being a unitary learning mechanism.

Journal ArticleDOI
TL;DR: Taylor’s paper purports to bridge the explanatory gap between neurophysiological function and phenomenal experience (PE), and suggests properties of PE, attempts to show how these properties map onto underlying neural information processing, and argues that a particular form of neural network, the locally recurrent network, has the requisite properties for producing the most elemental forms ofPE, or qualia.
