Performance disruption by startle-eliciting acoustic stimuli

Abstract

Six rats were trained to press a lever on a variable interval schedule of food reinforcement. When response rates were stable, a response-independent startle-eliciting acoustic stimulus was presented at intervals of approximately 6 min, and its disruptive effects were assessed. It was found that stimulus presentations yielded large decrements in response rate that persisted for several minutes. As daily test sessions proceeded, the decrements lessened, but even after 6 days of testing, startle stimuli continued to disrupt responding.
