Is our perceptual experience a veridical representation of the world or is it a product of our
beliefs and past experiences? Cognitive penetration describes the influence of higher level …

Two pairs of experiments studied the effects of attention and of unilateral neglect on auditory
streaming. The first pair showed that the build up of auditory streaming in normal participants …

When sensory input allows for multiple, competing perceptual interpretations, observers'
perception can fluctuate over time, which is called bistable perception. Imaging studies in …

Acoustic sequences such as speech and music are generally perceived as coherent
auditory" streams," which can be individually attended to and followed over time. Although …

Traces the historical development of the notion that two processes mediate apparent motion
percepts, examines evidence regarding their existence, and summarizes associated …

What has transpired immediately before has a strong influence on how sensory stimuli are
processed and perceived. In particular, temporal context can have contrastive effects …

Predictive coding theories propose that the brain creates internal models of the environment
to predict upcoming sensory input. Hierarchical predictive coding models of vision postulate …

It has recently been shown, using functional magnetic resonance imaging with a change
detection paradigm, that activity in posterior parietal cortex (PPC) correlates with the limited …

When spatially segregated visual stimuli are presented in alternation, subjects may perceive
a single stimulus moving between the two positions (apparent motion). By adjusting spatial …

Three theories of auditory stream segregation were evaluated. In two-part trials, subjects
heard an induction sequence, whose effects upon an immediately subsequent test …
