The visual system groups image elements that belong to an object and segregates them
from other objects and the background. Important cues for this grouping process are the …

Psychophysical experiments with stimuli oscillating concurrently in colour and orientation
revealed an apparently paradoxical dissociation between the perceived simultaneity of …

Computationally, audio-visual temporal synchrony detection is analogous to visual motion
detection in the sense that both solve the correspondence problem. We examined whether …

There is an ongoing debate whether visual object representations can be formed outside the
focus of voluntary attention. Recently, implicit behavioral measures suggested that grouping …

Dynamic environments often contain features that vary simultaneously as well as features
that vary sequentially. In principle, the correspondingly distinct sensations of simultaneity …

It is widely assumed that the separable features of visual objects, such as their colors and
shapes, require attention to be integrated. However, the evidence in favor of this claim …

We asked how dynamic facial features are perceptually grouped. To address this question,
we varied the timing of mouth movements relative to eyebrow movements, while measuring …

Our visual system organizes spatially distinct areas with similar features into perceptual
groups. To better understand the underlying mechanism of grouping, one route is to study its …

Consciousness is perhaps one of the greatest mysteries in the universe. This ambitious
book begins with a philosophical approach to consciousness, examining some key …

When the two eyes are presented with conflicting stimuli, perception starts to fluctuate over
time (ie, binocular rivalry). A similar fluctuation occurs when two patterns are presented to a …
