Abstract

The influence of the preceding conditioned reaction on the current conditioned performance was studied. Rats were trained to perform delayed and non-delayed spatial tasks in Y-maze. Two types of errors were analyzed: 1) the rats ran to the same maze arm as in the previous trial (errors of repetition), 2) the animals ran to the other arm (errors of alternation). It was shown that the alternation errors were more frequent under conditions of short intertrial interval and non-delayed choice. The repetition errors occurred more frequently under conditions of long intertrial interval and delayed choice. The obtained evidence supports the idea that not only cue presentation and delay periods are important for successful performance but the whole structure of the task influences the complex organization of the behavioural acts.

摘要

研究了先前的条件反应对当前条件表现的影响。大鼠在Y型迷宫中接受训练，以执行延迟和非延迟空间任务。分析了两种类型的错误：1）大鼠跑到与前一次试验相同的迷宫臂（重复错误），2）动物跑到另一个臂（交替错误）。结果表明，在短的试验间隔和非延迟选择条件下，交替错误更频繁。在长的试验间隔和延迟选择条件下，重复错误更频繁。所获得的证据支持这样一种观点，即不仅线索呈现和延迟期对成功表现很重要，而且任务的整体结构会影响行为动作的复杂组织。
