28名胎龄为40周的早产儿比28名胎龄相同的足月婴儿对二维刺激的注意时间明显更长（Exp I）。为了确定短暂的出生效应是否会降低足月婴儿的注意力，我们对15名足月婴儿在出生后的头2天和2周内的视觉注意力进行了测量（实验II）。在此期间，人们的注意力没有显著增加。此外，来自另外62名早产儿的数据显示，注视时间与产后经历的长度没有显著相关（实验III）。与出生状况有关的唯一注意力测量是对初始反应的测量。健康的婴儿在第一次接触刺激时的第一次注视时间稍长。对视觉刺激的初始反应可能比对不变的二维刺激的持续注意更准确地反映婴儿的注意力。（17 ref）（PsycINFO Database Record (c) 2016 APA，版权所有）
28 preterm infants tested at 40 wks conceptional age showed significantly longer periods of attention to 2-dimensional stimuli than did 28 full-term infants of the same conceptional age (Exp I). To determine whether attentiveness of the full-term infants was diminished by transient birth effects, visual attentiveness was measured in a group of 15 full-term infants in the 1st 2 days of life and 2 wks later (Exp II). There was no significant increase in attention over this period. Furthermore, data from 62 additional preterm infants showed that fixation times were not significantly related to length of postnatal experience (Exp III). The only attention measure relating to birth condition was a measure of initial responsiveness. Healthier infants showed slightly longer first fixations on the first exposure of the stimulus. Initial responsiveness to visual stimuli may represent infant attentiveness more accurately than sustained attention to unchanging 2-dimensional stimuli.(17 ref)(PsycINFO Database Record (c) 2016 APA, all rights reserved)
