使用一种名为中介范式的计算机化反转学习任务来评估卷尾猴的学习风格。首先，对猴子进行了训练，使其在二选一的辨别(A+B-)上的反应准确率达到90%。然后，作者检查了三种不同类型的逆转试验(A-B+，A-C+，B+C-)的表现差异，每种试验对表现的预测都不同，这取决于猴子使用的是联想线索还是基于规则的策略。表现表明，猴子在训练过程中主要学习避免B刺激，因为A-C+状态产生了最好的表现水平。因此，负性刺激对反转后的反应表现出更大的控制力，反映了一种更具关联性而不是基于规则的学习形式。
Learning styles in capuchin monkeys were assessed with a computerized reversal-learning task called the mediational paradigm. First, monkeys were trained to respond with 90% accuracy on a two-choice discrimination (A+B-). Then the authors examined differences in performance on three different types of reversal trials (A-B+, A-C+, B+C-), each of which offered differing predictions for performance, depending on whether the monkeys were using associative cues or rule-based strategies. Performance indicated that the monkeys mainly learned to avoid the B stimulus during training, as the A-C+ condition produced the best performance levels. Therefore, negative stimuli showed greater control over responding after reversal and reflected a more associative rather than rule-based form of learning.
