Relationships between imprinting and perceptual learning.

Abstract
Effect of early imprinting experience on later discrimination and avoidance learning was studied in 30 White Cornish chicks. A 1/2 -hr. imprinting experience during the 1st day of life and a subsequent 3-hr. group exposure to the same stimulus (visual flicker) on the 2nd day facilitated learning to approach and to avoid the original imprinting stimulus 1 mo. later. These effects, however, were observed only in Ss [subjects] which had shown the "approach behavior" during the early imprinting experience. The performance of those Ss which received an identical early exposure to the imprinting stimulus but did not approach it was not different from the performance of controls.
