Abstract

Six-month-olds (N=60) were tested in a habituation/dishabituation paradigm during which their heart rate was recorded. In the attention getter condition a salient stimulus appeared prior to each trial. In the no attention getter condition a blank slide appeared. It was hypothesized that the attention getter would lead to a heart rate decrease putting the infant into a state of sustained attention, and facilitate infants' encoding of the habituation stimulus. The encoding hypothesis was strongly supported. Infants in the attention getter condition showed shorter looking times during habituation and correspondingly an increased dishabituation response.

摘要

6 个月大的婴儿（N=60）在习惯化/去习惯化范式中接受测试，在此过程中记录他们的心率。在注意力吸引条件下，在每个试验前出现一个显著的刺激。在没有注意力吸引条件下，出现一个空白幻灯片。假设注意力吸引器会导致心率下降，使婴儿进入持续注意力状态，并促进婴儿对习惯化刺激的编码。编码假设得到了强有力的支持。在注意力吸引器条件下的婴儿在习惯化过程中表现出更短的注视时间，相应地增加了去习惯化反应。
