Rats pressed levers for water reinforcers delivered by multiple variable interval one-minute variable interval one-minute schedules. Experiment 1 manipulated the stimuli signalling the components of the multiple schedule. Experiment 2 varied the experimental environment. Responding changed significantly within the session during every condition of both experiments. Manipulating the component stimuli significantly altered the within-session pattern of responding; varying the environment did not. These results show within-session patterns of responding occur when subjects respond for water reinforcers. They also imply that contextually-based explanations for within-sessions patterns of responding are unlikely.
大鼠通过多重可变间隔一分钟-可变间隔一分钟的程序按压杠杆以获取水强化物。实验1操纵了指示多重程序各组成部分的刺激。实验2改变了实验环境。在两个实验的每种条件下，反应在实验过程中都有显著变化。操纵组成刺激显著改变了实验过程中的反应模式；改变环境则没有。这些结果表明，当受试者为获取水强化物而做出反应时，会出现实验过程中的反应模式。它们还意味着，基于情境对实验过程中反应模式的解释不太可能成立。
