在五个实验中，我们研究了婴儿期记忆提取中全局和局部线索的作用。六个月大的婴儿在家里一个独特的背景下（游戏围栏班轮）训练踢移动移动的。内衬为黄色，显示绿色条纹、条纹状列中垂直对齐的绿色方块或网格图案中的绿色方块。条纹和柱状衬垫具有相似的全局配置，但局部组件不同;柱状和网格衬垫具有相同的局部组件，但全局配置不同。当婴儿在训练后24小时进行测试时，在全局配置或局部特征与训练上下文不同的上下文衬垫的存在下，他们的记忆提取被破坏（实验1和2）。然而，从条纹到列的改变并没有破坏记忆提取，即使从列到条纹的反向改变也会破坏记忆提取。实验3，4和5表明，这种不对称性是由于这样一个事实，即当歧视性的本地信息是不直接与培训，后知觉策略使婴儿忽视训练和测试环境之间的本地信息的不匹配，并概括在24小时保持测试的基础上匹配的全球信息。因此，婴儿在事件发生的偶然环境中编码和记住全局配置信息和局部组件信息，并在响应新事件时灵活地利用这些信息。(C)1994年出版社出版。
In five experiments, we examined the role of global and local cues in memory retrieval in infancy. Six-month-old infants were trained at home in a distinctive context (playpen liner) to kick to move a mobile. The liners were yellow and displayed either green stripes, green squares aligned vertically in stripe-like columns, or green squares in a grid pattern. The stripes and columns liners had a similar global configuration but different local components; the columns and grid liners had identical local components but different global configurations. When infants were tested 24 h after training in the presence of context liners that differed from the training context in either global configurations or local features, their memory retrieval was disrupted (Experiments 1 and 2). However, a change from stripes to columns failed to disrupt memory retrieval, even though the reverse change, from columns to stripes, did. Experiments 3, 4, and 5 revealed that this asymmetry was due to the fact that, when discriminative local information is not directly associated with training, a postperceptual strategy enables infants to disregard a mismatch in local information between training and test contexts and to generalize on the basis of a match in global information during the 24-h retention test. Thus, infants encode and remember for substantial periods of time both global configuration information and local component information in the incidental context in which an event occurs and flexibly utilize this information when responding to new events.
