Infants with short look durations are generally thought to have better attentional capabilities due to their efficient information processing. Although effortful attention is considered a key component of developing regulatory abilities, little is known about the relation between speed and efficiency of processing and self-regulation. In this study, 5-month-old infants with shorter look duration had greater EEG power values than infants with longer look duration during baseline, as well as during a distressing task and a post-distress attentional processing task. These short looking infants also demonstrated higher heart rate, relative to long looking infants, during post-distress information processing. Behaviorally the two groups differed in the amount of distraction during distress. These data provide evidence for an association between the efficiency of information processing and beginning regulatory abilities in early infancy.
一般认为，目光注视持续时间较短的婴儿由于其有效的信息处理能力，具有更好的注意力能力。尽管努力注意被认为是发展调节能力的关键组成部分，但对于处理和自我调节的速度和效率之间的关系知之甚少。在这项研究中，与注视时间较长的婴儿相比，注视时间较短的 5 个月大的婴儿在基线时、在令人痛苦的任务中和在痛苦后注意力处理任务中具有更高的 EEG 功率值。这些短时间注视的婴儿在痛苦后信息处理过程中心率也相对高于长时间注视的婴儿。行为上，两组在痛苦期间分心的程度上有所不同。这些数据为信息处理效率与婴儿早期开始的调节能力之间的关联提供了证据。
