Recent research in both psychophysics and electrophysiology has revealed a number of examples in which behaviour is guided by (i.e. Spence & Driver, 1996), and brain activity has been argued to correlate with, the formation ...

Aside from their pharmacokinetic properties, e.g. their speed of action and the duration of residual effects, benzodiazepines are still considered as equivalent in terms of their effects on cognition. Here we review evidence ...

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 ...

We argue that the effectiveness of synchronization of oscillatory neural activities coding simple features, as it relates to perceptual organization, may originate in the temporal characteristics of resonance that develops ...

Detection of a target grouping is expedited when the target display is preceded by presentation of an oscillating premask that includes priming elements presented intraphasically and below detection threshold at the display ...

Studies on the involvement of object completions in search for illusory figures have so far reported equivocal results. We have addressed this issue by investigating at which level object attributes in Kanizsa figures ...

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 ...

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, ...
