This study examined the effect of attention on 3- to 6-month-olds responses to briefly exposed visual stimuli. In Study I, stimuli presented at 2.5 or 5.0 s resulted in a familiarity preference in a subsequent paired-comparison procedure. A novelty preference was found with 10.0- or 20.0-s exposure durations. In Study 2, a Sesame Street movie elicited heart-rate-defined attention phases and stimuli replaced Sesame Street during sustained attention, attention termination, or 5.0 s following attention termination. For 20 and 26-week-olds. Stimuli presented for 5.0 s during sustained attention resulted in a novelty preference similar to that found when exposure time was 20.0 s. The duration of stimulus exposure during sustained attention in the familiarization phase was positively correlated with the preference for the novel stimulus in the paired-comparison procedure. Thus, processing of briefly presented visual stimuli differs depending on the type of attention in which the infant is currently engaged.
本研究考察了注意力对3至6个月大婴儿对短暂呈现的视觉刺激的反应的影响。在研究I中，以2.5秒或5.0秒呈现的刺激在随后的配对比较程序中产生了熟悉度偏好。在10.0秒或20.0秒的暴露持续时间下发现了新奇偏好。在研究2中，一部《芝麻街》电影引发了以心率定义的注意力阶段，并且在持续注意力、注意力终止或注意力终止后5.0秒期间，刺激取代了《芝麻街》。对于20周和26周大的婴儿。在持续注意力期间以5.0秒呈现的刺激产生了你在暴露时间为20.0秒时发现的类似新奇偏好。在熟悉阶段持续注意力期间刺激暴露的持续时间与配对比较程序中对新刺激的偏好呈正相关。因此，根据婴儿当前所参与的注意力类型，对短暂呈现的视觉刺激的处理会有所不同。
