The approach and preference behaviour of chicks in relation to the intensity of neural-input effects.

Bengtsson, Hans LU (1983) In Animal Behaviour 31(2). p.490-496
Abstract
The approach tendency of young precocial birds has been found to be related to stimulus magnitude in an inverted U-shaped fashion. This paper discusses the coding and processing of stimulus information in 2 cases, namely, when the quantitative stimulus variable is (1) the size of a moving object and (2) flicker rate. It is shown that the optimal size of a moving object for eliciting approach can be derived from motion parameters that describe the growth in angular size of the projected retinal image as the object approaches the chick. A 2nd analysis provides support for the hypothesis that the chick's attraction to intermittent light in the vicinity of 4 flashes/sec can be related to the alpha rhythm of the chick's brain waves.
