The authors report a novel approach to testing episodic-like memory for single events. Pigeons were trained in separate sessions to match the identity of a sample on a touch screen, to match its location, and to report on the length of the retention interval. When these 3 tasks were mixed randomly within sessions, birds were more than 80% correct on each task. However, performance on 2 different tests in succession after each sample was not consistent with an integrated memory for sample location, time, and identity. Experiment 2 tested binding of location and identity memories in 2 different ways. The results were again consistent with independent feature memories. Implications for tests of episodic-like memory are discussed.
作者报告了一种用于测试单个事件类情景记忆的新方法。鸽子在不同的训练阶段接受训练,以在触摸屏上匹配样本的身份、匹配其位置,并报告保持间隔的时长。当这三项任务在各阶段内随机混合时,鸽子在每项任务上的正确率超过80%。然而,在每个样本之后连续进行的两项不同测试中的表现,并不符合对样本位置、时间和身份的整合记忆。实验2以两种不同方式测试了位置和身份记忆的绑定。结果再次与独立的特征记忆一致。文中讨论了对类情景记忆测试的启示。
