The major question posed in this research was whether 4- and 6-year-olds productively extend their knowledge by integrating information acquired in separate episodes. The vehicle was a read-aloud activity during which children were presented with a novel fact in each of two passages. In Experiment 1, both age groups showed evidence of integration between the passages. For the 6-year-olds, the evidence came in the form of responses to open-ended questions. The 4-year-olds recognized the correct answers but did not generate them in the open-ended question format. The 6-year-olds who generated the correct answers also were likely to recall both of the individual facts presented in the passages. In Experiment 2, we tested whether the 4-year-olds' integration performance would improve if their memory for the individual facts improved. Extra exposure to the individual facts resulted in higher levels of integration performance in both recall and recognition testing. The roles of memory and other potential sources of age-related differences in integration performance are discussed.
本研究提出的主要问题是,4 岁和 6 岁的儿童是否通过整合在不同情节中获得的信息来进行生产性扩展。研究采用的方法是大声朗读活动,在此过程中,孩子们在两个段落中分别呈现一个新的事实。在实验 1 中,两个年龄组都表现出了两个段落之间整合的证据。对于 6 岁的孩子来说,证据表现为对开放式问题的回答。4 岁的孩子虽然能够识别出正确答案,但不能以开放式问题的形式回答。那些能够生成正确答案的 6 岁儿童也很可能会回忆起两个段落中呈现的两个单独的事实。在实验 2 中,我们测试了如果儿童对单个事实的记忆得到改善,他们的整合表现是否会提高。在回忆和识别测试中,对单个事实的额外接触导致了更高水平的整合表现。本文还讨论了记忆和其他潜在的与年龄相关的整合表现差异来源的作用。
