This article presents data from 278 six-month-old infants who completed a visual expectation paradigm in which audiovisual stimuli were first presented randomly (random phase), and then in a spatial pattern (pattern phase). Infants' eye gaze behaviour was tracked with a 60 Hz Tobii eye-tracker in order to measure two types of looking behaviour: reactive looking (i.e., latency to shift eye gaze in reaction to the appearance of stimuli) and anticipatory looking (i.e., percentage of time spent looking at the location where the next stimulus is about to appear during the inter-stimulus interval). Data pertaining to missing data and task order effects are presented. Further analyses show that infants' reactive looking was faster in the pattern phase, compared to the random phase, and their anticipatory looking increased from random to pattern phases. Within the pattern phase, infants' reactive looking showed a quadratic trend, with reactive looking time latencies peaking in the middle portion of the phase. Similarly, within the pattern phase, infants' anticipatory looking also showed a quadratic trend, with anticipatory looking peaking during the middle portion of the phase.
本文呈现了278名6个月大婴儿的数据，这些婴儿完成了一个视觉预期范式，其中视听刺激首先随机呈现（随机阶段），然后以空间模式呈现（模式阶段）。为了测量两种注视行为，用60赫兹的托比眼动仪追踪婴儿的眼动行为：反应性注视（即对刺激出现做出眼动转移的潜伏期）和预期性注视（即在刺激间隔期间看向即将出现下一个刺激位置的时间百分比）。呈现了与缺失数据和任务顺序效应相关的数据。进一步分析表明，与随机阶段相比，婴儿在模式阶段的反应性注视更快，并且他们的预期性注视从随机阶段到模式阶段有所增加。在模式阶段内，婴儿的反应性注视呈现二次趋势，反应性注视潜伏期在该阶段的中间部分达到峰值。同样，在模式阶段内，婴儿的预期性注视也呈现二次趋势，预期性注视在该阶段的中间部分达到峰值。
