Predictive coding theories posit that the perceptual system is structured as a hierarchically
organized set of generative models with increasingly general models at higher levels. The …

When an image is presented to one eye and a very different image is presented to the
corresponding location of the other eye, they compete for conscious representation, such …

Normal people have a strikingly low ability to detect changes in a visual scene. This has
been taken as evidence that the brain represents only a few objects at a time, namely those …

Video cameras have a single temporal limit set by the frame rate. The human visual system
has multiple temporal limits set by its various constituent mechanisms. These limits seem to …

Most of the actions our brains perform on a daily basis, such as perceiving, speaking, and
driving a car, require timing on the scale of tens to hundreds of milliseconds. New …

Previous research has shown that when the targets of successive visual searches have
features in common, response times are shorter. However, the nature of the representation …

Visual feature integration theory was one of the most influential theories of visual information
processing in the last quarter of the 20th century. This article provides an exposition of the …

Overall performance when tracking moving targets is known to be poorer for larger numbers
of targets, but the specific effect on tracking's temporal resolution has never been …

Background Color and motion serve as the prime examples of segregated processing in the
visual brain, giving rise to the question how color-motion conjunctions are represented. This …

This is a survey of psychophysical studies of motion perception carried out mainly in the last
10 years. It covers a wide range of topics, including the detection and interactions of local …
