Abstract

Rats were conditioned to avoid shock on a free-operant avoidance schedule in which no exteroceptive stimulus signaled impending shock. Injections of adrenocorticotropic hormone (ACTH) or dexamethasone raised blood levels of glucocorticoids. These increases were accompanied by changes in avoidance performance: there was a higher frequency of long-duration interresponse times, a greater stability among them, and fewer short interresponse times, total responses, and shocks.

摘要

大鼠在自由操作回避程序中被训练以避免电击,该程序中没有外部感受性刺激预示即将到来的电击。注射促肾上腺皮质激素(ACTH)或地塞米松会提高糖皮质激素的血液水平。这些升高伴随着回避行为的变化:长时间反应间隔时间的频率更高,它们之间的稳定性更大,短反应间隔时间、总反应次数和电击次数更少。
