婴儿视觉注视持续时间的个体差异是可靠和稳定的，并且与不同的认知表现有关;短脸婴儿通常比长脸婴儿表现得更好。4个实验测试了矮个子在感知-认知任务上的优势是否归因于对视觉刺激的特征细节的注意，或者仅仅归因于视觉处理的速度或效率的差异。为了做到这一点，长和短看4个月大的表现进行了检查，在单独的歧视任务，可以解决只有通过处理功能或全球信息。整体任务比特征任务更容易，但随着分配给婴儿解决任何一种任务的时间减少，短眼婴儿的表现上级长眼婴儿。因此，这些结果支持婴儿注视持续时间的刺激处理解释的速度或效率。
Individual differences in the duration of infants' visual fixations are reliable and stable and have been linked to differential cognitive performance; short-looking infants typically perform better than long-looking infants. 4 experiments tested the possibility of whether short lookers' superiority on perceptual-cognitive tasks is attributable to attention to the featural details of visual stimuli, or simply to differences in the speed or efficiency of visual processing. To do this, the performance of long- and short-looking 4-month-olds was examined on separate discrimination tasks that could be solved only by processing either featural or global information. The global task was easier than the featural task, but as the amount of time allotted for infants to solve either type of task was decreased, short lookers' performance was superior to that of long lookers. These results thus lend support to a speed or efficiency of stimulus processing interpretation of infant fixation duration.
