Abstract
Adult rats, which had either been handled daily between birth and weaning or left undisturbed during this period, were tested on speed of emergence from the home cage. On opening the cage, handled animals reared sooner than did nonhandled ones, and females sooner than males; the additional time taken to raise the nose above the cage top showed sex differences only.
