title: Motion sickness-induced food aversions in the squirrel monkey.
abstract: Conditioned aversions to colored, flavored water were established in Squirrel monkeys (Saimiri sciureus) by following consumption with 90 min of simultaneous rotational and vertical stimulation. The experimental group (N = 13) drank significantly less of the green, almond-flavored test solution than did the control group (N = 14) during three post-treatment preference testing days. Individual differences were noted in that two experimental monkeys readily drank the test solution after rotational stimulation. Only two of the experimental monkeys showed emesis during rotation, yet 10 monkeys in this group developed an aversion. These results that (1) motion sickness can be readily induced in Squirrel monkeys with simultaneous rotational and vertical stimulation and (2) that conditioned food aversions are achieved in the absence of emesis in this species.
