✦ Synopsis

If each mouse killed by a rat is removed from the rat's home cage and replaced immediately by another live mouse, the rate of killing declines within 1-and 3-hr sessions. Muricide could not then be dishabituated by either a "nonspecific" stimulus (a loud noise) or a specific change in target characteristics (a frog substituted for the mouse). By systematically varying intersession intervals, we found that 1 hr of ad lib killing produced a monotonically decreasing suppression of muricide over the succeeding 96 hr. Subjects performed an interesting kind of forward d i d n g which was influenced by both dishabituating stimuli and killing; this may be a form of die placement behavior.
