Low time resolution in schizophrenia: Lengthened windows of simultaneity for visual, auditory and bimodal stimuli
(Elsevier, 2007-12)
The guarantee of perceptual coherence for events through everyday life situations depends upon the capacity to correctly integrate series of multi-sensory experiences. Patients with schizophrenia have been shown to reveal ...
Electrophysiological correlates of similarity-based interference during detection of visual forms
(MIT Press, 2006-06)
Illusory figure completion demonstrates the ability of the visual system to integrate information across gaps. Mechanisms that underlie figural emergence support the interpolation of contours and the filling-in of form ...
The effects of subthreshold synchrony on the perception of simultaneity.
(Springer, 2007)
We aimed to examine the effects of subthreshold synchrony and asynchrony on the perception of simultaneity. We rendered simultaneous or asynchronous luminance changes below detection thresholds by embedding them in a ...
Synchronization and stimulus timing: Implications for temporal models of visual information processing.
(Lawrence Erlbaum and Associates / Psychology Press (Taylor & Francis), 2004)
In the visual system, objects and object groupings may be initially coded in terms of
physically separable attributes or features, representing differential spatial frequencies,
orientations, colors, directions of motion, ...
Evidence for impaired visuo-perceptual organization in developmental dyslexics and its relation to temporal processes.
(Taylor & Francis, 2005-07)
An analysis of normal and dyslexic readers' reaction-time (RT) performance in a standard visualdetection task (Experiment A) and in temporally primed visual detection (Experiment B) reveals a tendency for significantly ...
Closure of salient regions determines search for a collinear target configuration
(Psychonomic Society, 2007-01)
Grouping operations offer an effective mechanism by which to structure complex visual scenes. Among the various principles that support element integration, closure may be regarded as a main factor in shape extraction. In ...
The dynamics of operations in visual memory: A review and new evidence for oscillatory priming
(Hogrefe & Huber, 2004-10)
Evidence from neurophysiological studies indicates that the synchronization of distributed neuronal assemblies in the gamma frequency range is responsible for the integration of discrete stimulus components into coherent ...
Some facilitatory effects of lorazepam on dynamic visual binding
(Springer, 2006)
Rationale: The benzodiazepine lorazepam enhances the potential for inhibitory (GABAA) synapses in the cortex to stabilize postsynaptic, excitatory activity by synchronizing discharge rates at frequencies of around 40 Hz. ...
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 ...
