摘要
本文探讨不同年龄猕猴(Macaca mulatta)反转学习(reversal learning)的比较生理研究。结果表明幼年猕猴(6—11月)的反转学习已达到较高水平,至少不比成年猴的神经过程灵活性差,而接近中年的猴(10—12岁)神经过程灵活性则有所降低。此外,不同年龄猕猴的颜色反转均较形状反转困难,同时,阳性(+)至阴性(—)的困难反转(即“先—后+”的错误)是不同年龄猕猴反转学习中的共同特征。
Fourteen experimentally normal thesus monkeys served as Ss(subjects).There were 5 Ss in the age group of 6-11 months,7 Ss in 2-7 years and 2 Ss in 10-12 years.Reversal learning was studied by the method of imultancous presentations of positive and negative ctimuli.All testing was carried out with a modified WGTA.Training commenced with each s to reach a criterion of 80%correct in 2-3 saecssive trials of"stereotype".Next,the"stereotype"was reversed,until s reached the same criterion again.The results of the experiments were a follows.
