摘要: 一、在5只正常猕猴上进行了圆锥体与圆柱体的分辨反转学习训练。对反转后即刻分辨、反转学习速度和长时记忆作了观察。结果表明,随着反复训练,反转后即刻分辨正确率逐步有所提高,反转学习速度也可进一步加快。此外,猴对反转后即刻分辨的长时记忆也是相当巩固的。 二、两侧前额叶背侧面皮层切除后,分辨反转受到影响。这主要表现在反转后即刻分辨的正确率显著下降,动物出现“顽固性”错误。一侧手术后影响不大。

Abstract: 1. Five normal rhesus monkeys were trained on object discrimination reversal, cylinder and cone were used as the discrimination throughout theexperiment. The rate of discrimination reversal learning, the immediatediscrimination after reversal (reversal phase) and the retention of discrimi-nation reversal (retention phase, 11 days) were observed. The results showedthat the rate of reversal learning and the percentage of correct reponses inreversal phase were improved in repeated training. Animals had also a goodperformance on discrimination task in retention phase. 2. Dorsolateral prefrontal cortex lesions impaired discrimination reversal.Bilateral lesions would result in impaired performance more severely thanunilateral ones. The prefrontal resected monkeys made more error trials inreversal phase and so decreased the rate of reversal learning retrainingtasks.
