Five years ago, pigeons trained to peck a key for food were periodically presented with a 1000 cps tone which ended with electrical shock. They were then tested for the stimulus generalization of conditioned suppression. After an interruption of 2.5 yr, another series of generalization tests showed no loss of suppression. The present study was conducted 1.5 yr later to retest the effect of an extended interruption on retention of suppression. It was found, again, that suppression did not decline over time. The present paper, which summarizes the earlier data and reports the most recent findings, provides an overview of the extended behavioral consequences of the original aversive procedures administered five years ago.
五年前，训练通过啄键获取食物的鸽子会定期听到1000赫兹的音调，随后会遭受电击。然后对它们进行条件性抑制的刺激泛化测试。在中断2.5年后，另一系列泛化测试表明抑制作用没有丧失。1.5年后进行了本研究，以重新测试延长的中断时间对抑制作用保持的影响。再次发现，抑制作用并没有随时间下降。本文总结了早期数据并报告了最新发现，概述了五年前实施的原始厌恶程序所产生的长期行为后果。
