Temporal tolerance circumscribed
(Taylor & Francis, 2005-05)
Chen's topological theory of perceptual organization includes the idea that equivalences in spatial organization and the organization of subjective experiences of time may be derived by means of common expression in terms ...
Dynamics of perceptual grouping: similarities between the organization of visual and auditory groups
(Taylor & Francis, 2001-06)
In vision, the Gestalt principles of perceptual organization are generally well understood and remain a subject of detailed analysis. However, the possibility for a unified theory of grouping across visual and auditory ...
Comparing temporal event-coding in patients with first episode psychosis and chronic schizophrenia
(Elsevier, 2008-06)
Cognitive impairments are a core feature of schizophrenia. It has been suggested that the underlying cause of the cognitive deficits in schizophrenia is an impaired ability to sequence mental activity in time. Various ...
An investigation of cognitive dysmetria in developmental dyslexia
(Pion Ltd, 2006)
An alternative to theories positing visual or phonological deficits, the 'cognitive dysmetria' hypothesis proposes the aetiology of dyslexia to take the form of a general functional coordination deficit or cognitive ...
Prefrontal cortex and the generation of oscillatory visual persistence
(Cambridge University Press, 2003-12-01)
In this commentary, the formation of "pre-iconic" visual-prime persistence is described in the context of prime-specific, independent-component activation at prefrontal and posterior EEG-recording sites. Although this ...
Electrophysiological correlates of flicker-induced color hallucinations
(Elsevier, 2009-03)
In a recent study, Becker and Elliott [Becker, C., & Elliott, M. A. (2006). Flicker induced color and form: Interdependencies and relation to stimulation frequency and phase. Consciousness & Cognition, 15(1), 175-196] ...
Visual perception in a snapshot
(Springer, 2006-04-14)
To study visual perception in its sub-second scale of
time continues to be timely: we have more unsolved
puzzles than bits of a firm undisputable knowledge
about how our perceptions are created in a snapshot of
time. ...
Enhanced GABA-A inhibition enhances synchrony coding in human perception
(Lippincott Williams & Wilkins, 2000-10-20)
The benzodiazepine, lorazepam enhances the efficiency of local, inhibitory GABAA synapses in the cortex, which stabilize postsynaptic, excitatory activity by synchronizing their own discharges at around 40 Hz. Treatment ...
Prefrontal cortex and the generation of oscillatory visual persistence
(Cambridge University Press, 2003)
In this commentary, the formation of ¿pre-iconic¿ visual-prime persistence is described in the context of prime-specific, independent-component activation at prefrontal and posterior EEG-recording sites. Although this ...
Evidence for 40-Hz oscillatory short-term visual memory revealed by human reaction-time measurements
(American Psychological Association, 2000-05)
Four experiments show that presentation of a synchronous premask frame within a 40-Hz, flickering premask matrix primes subsequent detection of a Kanizsa-type square by generation of a 40-Hz prime. Reaction time (RT) priming ...
