Information trial and successive reversal training effect in Japanese monkeys

概要

論文の詳細を見る
Two groups of male Japanese monkeys were given one of two modified forms of successive reversal training (SRT) in WGTA. Prior to usual SRT trials of each reversal, an information trial was introduced on which either baited positive stimulus [(p-1) group; <I>n</I>=3] or unbaited negative stimulus [(n-1) group; <I>n</I>=2] of new reversal was singly presented. Two-trial problems were given on three stages of the informed SRT's so as to assess the development of choice strategies.(N-1) group tended to be superior to (p-1) group in 2-trial problems, and the latter group was inferior to (n-3) and SRT groups of the previous experiments. An assumption explaining these and other findings was presented.
