Showing papers in "Consciousness and Cognition in 2004"

TL;DR: It is suggested that the way the authors both remember their past and imagine their future is constrained by their current goals.

TL;DR: The results suggest the authors can dissociate between two components of subjective experience during sustained attention: task unrelated thought which corresponds to an absent minded disengagement from the task and a pre-occupation with one's task performance that seems to be best conceptualised as a strategic attempt to deploy attentional resources in response to a perception of environmental demands which exceed ones ability to perform the task.

TL;DR: It is proposed that a necessary prerequisite to the experience of flow is a state of transient hypofrontality that enables the temporary suppression of the analytical and meta-conscious capacities of the explicit system.

TL;DR: Evidence is presented that speed at different stages of the perceptual process contributes to perceptual fluency, and it is suggested that speed of processing at various stages condensed into a unified subjective experience of perceptualfluency.

TL;DR: A conceptual analysis of the empirical data will lead to the establishment of the taxonomy of the different levels of action representations, and the definition of the sense of agency should be refined by distinguishing thesense of initiation andThe sense of one's own movements.

TL;DR: The study of ambiguity gives insight into how activity at different stations of the brain can result in a micro-consciousness for an attribute, and also gives insights into the neurological machinery that artists have tapped to create the ambiguity that is commonly a hallmark of great works of art.

TL;DR: The data suggest that definable states of brain activity and subjective experiences exist, in addition to waking, sleeping and dreaming, that may be operationally defined by psychological and physiological measures along a continuum of Object-referral/Self-reFERral Continuum of self-awareness.

TL;DR: The results of all three experiments support the notion that the maintenance of spontaneously occurring images and thoughts is simultaneously influenced by both the semantic content and the personal salience of the information held in working memory.

TL;DR: Concious accessibility is not either-or but more or less, and variable over time, and some laboratory evidence suggests that accessibility measures, as they approach chance, may actually dip below chance (subchance perception).

TL;DR: Hypnosis itself had no effect on the subjective experience of voluntariness associated with willed movements and passive movements or on time estimations of their occurrence, but subjective time estimates of a hypnotically-suggested, 'involuntary' finger movement were more similar to those for passive movements than for voluntary movements.

TL;DR: It is found that color priming in normal observers is significantly reduced when an additional paracontrast mask precedes the target at optimal masking SOAs, however, no reduction of form-priming effects was obtained at similar optimal parAContrast SOAs.

TL;DR: Three priming experiments were conducted to determine how information about the self from different sensory modalities/cognitive domains affects self-face recognition, and the finding of a left-hand advantage for self- face recognition was replicated when no primes were presented.

TL;DR: This article sketches an idealized strategy for the identification of neural correlates of consciousness based on a state space approach originating from the analysis of dynamical systems, which focuses on one constituent of consciousness, phenomenal awareness.

TL;DR: The findings confirm the existence of sex-related influences in the recall of emotional information, and suggest that sex- related traits, rather than actual sex per se, may be a more sensitive indicator of these influences.

TL;DR: In four experiments using an artificial grammar (AG) learning procedure, the authors examined the links between the "classic" mere exposure effect [heightened affect for previously encountered stimulus items] and the "structural" mere Exposure effect [greater hedonic appreciation for novel stimuli that conform to an implicitly acquired underlying rule system (Gordon & Holyoak, 1983].

TL;DR: Motivational and emotional content was significantly greater in REM than NREM sleep, even after controlling for the greater word count of REM reports.

TL;DR: Evidence and arguments are presented showing that visual masking techniques, by revealing more detailed aspects of target masking and target recovery, support a theoretical approach to visual masksing and visual perception that must take into account activities in two separate neural channels or processing streams.

TL;DR: This work exploits motion-induced blindness to investigate the related question of the influence of visual awareness on the formation of negative afterimages, and shows that MIB does not affect the persistence and intensity of afterimages.

TL;DR: It was found that the magnitude and time course of activation within the anterior cingulate, medial prefrontal cortex, and frontopolar cortex predicted whether or not information was consciously perceived during the critical period for the attentional blink.

TL;DR: The data suggest that in some delusional schizophrenic patients, it may be possible to gain access to and modify their mental states when perspective is shifted from the first person to third person.

TL;DR: This paper found that the verbal span of the high-dissociative group was about half a word larger than of the medium and low-disociative groups, and suggested that dissociative style may be one of only very few individual differences that is directly relevant to consciousness research.

TL;DR: This paper explicates Proust's theory of conscious experience and shows how it leads him directly to a theory of aesthetic perception, and proposes a possible neural basis for this ProuStian/Jamesian phenomenology.

TL;DR: Variations in interhemispheric interaction (as measured by degree of handedness) contribute to differences in consciousness, specifically when consciousness is used in rumination versus the metacognitive task of self-reflection.

TL;DR: A review of the literature suggests that conclusion that learning is thought to occur in the absence of contingency or demand awareness may be premature because measures of awareness lack the rigor that is found in studies of other kinds of human learning.

TL;DR: Results indicated that the chronostasis effect is constant across a wide range of stimulus durations and does not reflect the pattern of visual stimulation experienced during a saccade, suggesting that arousal is not critical.

TL;DR: It is suggested that significant progress on construct validity issues is possible and below-chance effects are part of a more general bidirectional phenomenon, very likely unconscious, and do not threaten absolute subliminality; practice/learning effects pose potential difficulties for time-based dissociation paradigms.

TL;DR: The causal relationships implicit in definitions of access consciousness and phenomenal consciousness are made explicit, and the corresponding causal relationships at the more detailed levels of perception, memory, and skill learning are described.

TL;DR: It is concluded that visual attention may result in far more transitory awareness of visual information than previously appreciated.

TL;DR: The results of this fMRI study provide further support for the theory that the initial creation of perceptual awareness and upholding perceptual awareness over time are separate processes involving different brain regions.
