in which the concepts and techniques of information theory may clarify our understanding of visual perception. When we begin to consider perception as an information-handling process, it quickly becomes clear that much of the information received by any higher organism is redundant. Sensory events

for computing capacity will continue to increase, with no practical bound in sight. I have divided the papers on which I comment into three groups: visual perception, models and neural networks, and data analysis.

Behavioural experiments have shown an interesting connection between how well one knows something and how much one likes it. This is the so-called mere exposure effect(1). This effect has also been found for music perception(2). However, the neural correlates for the phenomenon are not well

Progress in reading instruction depends to a great extent on perception and cognition. Percep-tion depends upon the performance of sensory organs, quality of the circumstances attendant to the act of perception and the attitudes and predisposition of the perceiver which affect the quality of his

• Human eye is able to capture all wavelengths in the range 250-780 nm • Eye sensitivity depends on the wavelength: for a given energy level, the radiation is perceptually received as more or less intense depending on λ • The colour is a function of the wavelength and of the energy that it emits or reflects • Two receptors: retinal cones and rods. Cones are more sensitive to wavelength, rods to energy Pag. 2 Video coding
