Abstract
Tests of imprinting were initiated at various hours after hatching in neonate chicks. The imprinting object was a 7-inch green cube which was exposed for 30 minutes. Retention tests were given after 10 days. Results demonstrated the existence of a critical imprinting period, the percentage of animals imprinted declining more or less regularly from near 90% 1[long dash]6 hours after hatching, to zero 54[long dash]60 hours after hatching. However, the older the animal, the more vigorous is following performance if imprinting does occur; retention shows similar trends. There is some evidence of latent imprinting.Keywords
