Hemispheric asymmetry of learning-induced changes
Statistical tests for an interaction in a factorial experiment are less sensitive than tests for a corresponding main effect because their associated standard errors are larger. Evidence suggests that the intermediate and medial part of the hyperstriatum ventrale (IMHV) plays a crucial role in the learning process of imprinting and is a site of information storage. The effect of bilateral lesions to IMHV depends on the time relative to training at which the lesions are placed. Also, there is evidence that the left and right eyes of the young chick have access to different brain systems, at least partly located in the right and left sides, respectively, of the brain. There is however no reason to suppose that unequal stimulation of the two eyes – which produces lateralization of visual forebrain connections, visual discrimination learning, and the control of copulation and attack behaviour – is necessary for the hemispheric asymmetry associated with imprinting.
