Attention modulates spatio-temporal grouping
Dynamic stimuli are ubiquitous in natural viewing conditions implying that grouping operations need to operate, not only in space, but also jointly in space and time. Moreover, in natural viewing, attention plays an important role in controlling how resour ...
Elsevier2011The roles of mask luminance and perceptual grouping in visual backward masking
Michael Herzog, Gregory Francis
Visual backward masking is a commonly used technique in vision research and psychology. There are two distinct types of masking. Either masking is strongest for a simultaneous presentation of the target and the mask (A-type masking) or masking is strongest ...
Association for Research in Vision and Ophthalmology2009Shape distortions and Gestalt grouping in anorthoscopic perception
When a figure moves behind a stationary narrow slit, observers often report seeing the figure as a whole, a phenomenon called slit viewing or anorthoscopic perception. Interestingly, in slit viewing, the figure is perceived compressed along the axis of mot ...
Association for Research in Vision and Ophthalmology2009Assessing the microstructure of motion correspondences with non-retinotopic feature attribution
The motion correspondence problem, one of the classical examples of perceptual organization, addresses the question of how elements are grouped across space and time. Here, we investigate motion correspondences using a new feature attribution technique. We ...
Association for Research in Vision and Ophthalmology2008Contrast polarity, chromaticity, and stereoscopic depth modulate contextual interactions in vernier acuity
Vernier alignment thresholds are strongly compromised when the vernier is embedded in an array of equal-length flanking lines. Here, we show that these contextual interactions can be diminished by giving the flanks the opposite contrast polarity, e.g., whi ...
Association for Research in Vision and Ophthalmology2008Grouping effects in flash-induced perceptual fading
We show that the flash-induced fading effect can be influenced by grouping based on colour and shape similarity. In flash-induced fading, peripherally presented elements perceptually disappear after a flash has been presented around or next to the element( ...
2007Perceptual grouping induces non-retinotopic feature attribution in human vision
The human visual system computes features of moving objects with high precision despite the fact that these features can change or blend into each other in the retinotopic image. Very little is known about how the human brain accomplishes this complex feat ...
