Defining perceptual synchrony
(Kijima Printing Co., 2007)
How does neuronal activity bring about the interpretation of visual space in terms of objects or complex perceptual events? If they group, simple visual features can bring about the integration of spikes from neurons ...
New measures of functional (but not perceptual) continuity in visual grouping
(International Society for Psychophysics, 2004)
The benzodiazepine, Lorazepam enhances the efficiency of inhibitory GABA-A synapses in the cortex, which stabilize postsynaptic, excitatory activity by synchronizing their own discharges at around 40 Hz. Lorazepam treatment ...
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 ...
Some effects of negative delays upon the perception of causal relatedness
(The International Society for Psychophysics, 2004)
We examined the effects of negative delays on the perception of causality using a variation of the paradigm originated by Michotte (1954) and as an extension to similar work conducted by Kanizsa and Vicario (1968). In our ...
Expectancy, not memory determines identical search rates in static and dynamic displays.
(International Society for Psychophysics, 2005)
Search rates are often used as a measure of search efficiency. Horowitz & Wolfe employed this measure to compare static and dynamic visual search (Horowitz & Wolfe, 1998). Based on identical search rates, they argued that ...
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 ...
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 ...
