Abstract

An experiment was conducted to assess the effectiveness of providing response-contingent stimuli in improving the performance of rats with septal lesions on a DRL schedule of reinforcement. Groups of operated and control animals were given no stimulus, a light flash, or footshock in conjunction with all noncriterion lever presses. Footshock, but not light, was found to substantially ameliorate the lesion-induced DRL deficit. Improved schedule efficiency appeared to result from the punishing aspects of the shock and not to a response-feedback function.

摘要

进行了一项实验，以评估在DRL强化程序中提供反应相依刺激对改善患有隔区损伤大鼠的表现的有效性。对手术组和对照组动物，结合所有未达标准的杠杆按压给予无刺激、闪光或电击。结果发现，电击而非闪光能显著改善损伤引起的DRL缺陷。日程效率的提高似乎源于电击的惩罚作用，而非反应反馈功能。
