Abstract: | Systemic injections of cholinomimetic drugs have been reported to induce both rage and predatory attack in several species. In order to assess the relative contribution of each of these two behavioral patterns in the control of cholinergically induced attack, a group of adult female cats was chemically stimulated in the simultaneous presence of both a prey object and a conspecific attack object. In this choice situation stimulated cats initially tended to engage in rage attack. When a second group of subjects was tested in a successive choice situation a significantly greater number of attacks occurred against conspecifics. The results suggest that cholmergic stimulation initially induces affective attack, with somewhat less frequent incidents of predation. |
