Infants can imitate a novel action sequence from television and picture books, yet there has been no direct comparison of infants' imitation from the 2 types of media. Varying the narrative cues available during the demonstration and test, the current experiments measured 18- and 24-month-olds' imitation from television and picture books. Infants imitated from both media types when full narrative cues (Experiment 1; N = 76) or empty, meaningless narration (Experiment 2; N = 135) accompanied the demonstrations, but they imitated more from television than books. In Experiment 3 (N = 27), infants imitated from a book based on narration alone, without the presence of pictures. These results are discussed in relation to age-related changes in cognitive flexibility and infants' emerging symbolic understanding.
婴儿可以模仿电视和图画书中的新动作序列,但尚未直接比较婴儿从这两种媒体的模仿情况。通过在演示和测试过程中改变可用的叙述线索,当前的实验测量了 18 个月和 24 个月大的婴儿从电视和图画书中的模仿情况。当演示时提供完整的叙述线索(实验 1;N = 76)或空的、无意义的叙述(实验 2;N = 135)时,婴儿会模仿这两种媒体类型,但他们从电视中模仿的更多。在实验 3(N = 27)中,婴儿仅根据叙述模仿书本,而没有图片。这些结果与认知灵活性的年龄相关变化以及婴儿正在发展的符号理解有关。
