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

The phenomenon of non-Fourier motion (visually perceived motion that cannot be explained
simply on the basis of the autocorrelation structure of the visual stimulus) is well recognized …

Recent research suggests that human symmetry-detection mechanisms cannot
simultaneously compare different colors across the axis of symmetry (Nature 399 (1999) …

Previous work has shown that a single dot moving in a consistent direction is easily detected
among noise dots in Brownian motion (Watamaniuk et al.,(1995). Vis Res, 35, 65–77). In this …

Several different types of motion mechanisms function in the human visual system. The
purpose of this study was to clarify the type of reference frame, such as retinotopic and …

Changing the speed, size and material properties of optic flow can significantly alter the
experience of vection (ie visually induced illusions of self-motion). Until now, there has not …

Cognitive psychology is the scientific investigation of human cognition, that is, all our mental
abilities–perceiving, learning, remembering, thinking, reasoning, and understanding. The …

It is now well established that monkey extrastriate cortex, the visual cortex beyond primary or
striate cortex, contains many different areas (for review, see Van Essen et al., 1992; …

A continuous periodic motion stimulus can sometimes be perceived moving in the wrong
direction. These illusory reversals have been taken as evidence that part of the motion …

Convergent physiological and behavioral evidence indicates that the initial receptive fields
responsible for motion detection are spatially localized. Consequently, the perception of …
