Shape and motion interactions at perceptual and attentional levels during processing of structure from motion stimuli.

27 Dec 2008 This study uses a rapid-serial-visual-presentation (RSVP) paradigm to test the extent to which shape and motion direction can be independently accessed and processed during the perception of structure-from-motion (SFM) stimuli. Subjects reported the ...

Birds of a feather flock together: experience-driven formation of visual object categories in human ventral temporal cortex.

22 Dec 2008 The present functional magnetic resonance imaging study provides direct evidence on visual object-category formation in the human brain. Although brain imaging has demonstrated object-category specific representations in the occipitotemporal cortex, ...

A Bayesian framework for cue integration in multistable grouping: Proximity, collinearity, and orientation priors in zigzag lattices.

22 Dec 2008 Integration of proximity and good continuation cues is analyzed as a probabilistic inference problem in contour grouping. A Bayesian framework was tested in a multistable dot lattice experiment. In rectangular lattices, distance ratio and global ...

Object perception is selectively slowed by a visually similar working memory load.

20 Dec 2008 The capacity of visual working memory has been extensively characterized, but little work has investigated how occupying visual memory influences other aspects of cognition and perception. Here we show a novel effect: maintaining an item in visual ...

The perception of illusory transparent surfaces in infancy: early emergence of sensitivity to static pictorial cues.

20 Dec 2008 Most developmental studies consistently show that sensitivity to purely pictorial cues to perceptual organization emerges around 6-7 months of age (e.g. B. I. Bertenthal, J. J. Campos, & M. M. Haith, 1980). Here, we show evidence for an early ...

Stimulus dependency and mechanisms of surround modulation in cortical area MT.

15 Dec 2008 The perceptual interpretation of a given visual feature depends on the surrounding context. To explore the neural mechanisms underlying such contextual interactions in the motion domain, we studied responses of neurons in the middle temporal area ...

Saccadic eye movement programming: sensory and attentional factors.

14 Dec 2008 The relationship between attention and eye movements is explored by consideration of the variety of ways attention may affect saccade programming. Four forms of attention are distinguished: one exogenous and three endogenous through either locations ...

Inhibitory competition in figure-ground perception: context and convexity.

13 Dec 2008 Convexity has long been considered a potent cue as to which of two regions on opposite sides of an edge is the shaped figure. Experiment 1 shows that for a single edge, there is only a weak bias toward seeing the figure on the convex side. ...

A quantitative explanation of responses to disparity-defined edges in macaque V2.

8 Dec 2008 Previous experiments have shown that V2 neurons respond to complex stimuli such as cyclopean edges (edges defined purely by binocular disparity), angles, and motion borders. It is currently unknown whether these responses are a simple consequence of ...

Preattentive surface and contour grouping in Kanizsa figures: evidence from parietal extinction.

4 Dec 2008 Visual extinction commonly occurs after unilateral, parietal brain damage and manifests in a failure to identify contralesional stimuli when presented simultaneously with other, ipsilesional stimuli - but full awareness for single stimulus ...
