Abstract
Examined the behavioral characteristics which differentiate wild and domesticated mice together with some of the possible mechanisms which produce them. 1 wild stock, 3 inbred strains (C57 B1/10j, DBA/2j, and A/j), and 3 inbred crosses (N = 277) were divided by litter at weaning and assigned in equal numbers to a laboratory or naturalistic environment. After 90 days Ss were run through a test battery. Wild Ss were characterized by poor avoidance, high activity, long emergence latencies, and extensive freezing behavior. Hybrids were not consistently more like wilds than inbreds and showed little effect of differential rearing. Wilds and inbreds differed in their response to differential rearing.
