Two experiments examined the content of configural learning in rats. In Experiment 1, after simple pre-exposure to two hybrid contexts (AB and CD), rats acquired a configural discrimination involving two of the contexts (A and C) and two auditory stimuli (X and Y; AX→food, AY→no food, CX→no food, and CY→food). When rats were then placed in context B, they were more likely to respond to X than Y, and when they were placed in context D the reverse was the case. Experiment 2 demonstrated that rats can acquire a configural discrimination involving the presence of context (A) and its memory trace (a; AX→food, AY→no food, aX→no food, and aY→food). These results show that associatively provoked memories (Experiment 1) and memory traces (Experiment 2) can participate in configural discriminations.
两项实验研究了大鼠构型学习的内容。在实验1中,大鼠在简单预暴露于两种混合情境(AB和CD)后,获得了一种涉及其中两种情境(A和C)以及两种听觉刺激(X和Y;AX→食物,AY→无食物,CX→无食物,CY→食物)的构型辨别能力。当大鼠随后被置于情境B中时,它们对X的反应比对Y的反应更有可能;而当它们被置于情境D中时,情况则相反。实验2表明,大鼠能够获得一种涉及情境(A)及其记忆痕迹(a;AX→食物,AY→无食物,aX→无食物,aY→食物)的构型辨别能力。这些结果表明,联想引发的记忆(实验1)和记忆痕迹(实验2)可以参与构型辨别。
