Three pigeons were each trained to perform a discrimination problem and a matching problem. Following acquisition, delays of 1 to 7 sec were interposed after stimulus presentation on both problems. Accuracy of responding on these two types of delay procedures was observed to be a function of length of delay interval. Performance was consistently poorer on the delayed matching problem than on the delayed discrimination problem.
三只鸽子分别接受训练,以执行辨别任务和匹配任务。在习得之后,在这两个任务的刺激呈现之后插入1到7秒的延迟。观察到在这两种延迟程序上的反应准确性是延迟间隔长度的函数。在延迟匹配任务上的表现始终比延迟辨别任务上的表现差。
