The persistence of attack satiation in female golden hamsters

Female hamsters were allowed to attack a series of target hamsters until they reached a criterion of attack satiation. Following delays of 0, 24, or 48 hr they were then presented with a novel “probe” target. Attacks on the probe target were reduced to 26% of baseline at 0 delay and had returned to 71% of baseline by 48 hr. The number of attacks necessary to achieve satiation criterion increased then decreased over the three test occasions, suggesting that habituationlike processes may contribute to, but cannot wholly account for, the satiation effect.
