Levels of Perception

In this book the authors relate and discuss the idea that perceptual processes can be considered at many levels.

A phenomenon that appears at one level may not be the same as a superficially similar phenomenon that appears at a different level.

For example "induced motion" can be analyzed in terms of eye movements or at the retinal level or at a much higher cognitive level: how do these analyses fit together? The concept of levels also makes us think of the flow of information between levels, which leads to a consideration of the roles of top- and bottom-up (or feed-forward, feedback) flow.

There are sections devoted to vestibular processing, eye movement processing and processing during brightness perception.

The final section covers levels of processing in spatial vision.
