Abstract

In a multiple variable-interval extinction schedule, pigeons' responses on an operant key were differentially reinforced in the presence of discriminative stimuli located on a signal key. Changeover delays of zero, one, two, or four seconds specified the time following a signal-key response within which an operant-key response was not reinforced. Systematic reduction of signal-key response rates with increasing changeover-delay duration indicated that signal-key responding was largely maintained by reinforcement of adventitious signal-key/operant-key response chains.

摘要

在多变量间隔消退程序中,在位于信号键上的辨别性刺激出现时,鸽子对操作键的反应得到差别强化。零秒、一秒、两秒或四秒的转换延迟规定了信号键反应之后的一段时间,在此期间操作键反应不会得到强化。随着转换延迟持续时间的增加,信号键反应率系统性降低,这表明信号键反应在很大程度上是由偶然的信号键/操作键反应链的强化维持的。
