Comparative and developmental study on the temporal integration process of visual information in primates

虽然人类倾向于在分析视觉物体识别的局部特征之前处理全局特征（全局优先效应），但累积的比较和发展研究表明，全局优先并不一定发生在非人类灵长类和鸟类物种以及人类婴儿中。本研究通过使用狭缝观察任务来检查黑猩猩和人类成年人以及3至12个月大的人类婴儿整合全局运动和全局形状信息的能力。结果表明，人类在整合时空信息的能力上上级黑猩猩，这种能力在人类婴儿5个月大时就出现了。

While humans tend to process global features before analyzing local features on the visual object recognition (global precedence effect), accumulative comparative and developmental studies have shown that the global precedence does not necessarily occur in nonhuman primates and avian species, and human infants. The present study examined the ability to integrate global motion and global form information in chimpanzees and human adults, and 3 to 12-month-old human infants by using a slit-viewing task. The results suggest that humans were superior to chimpanzees in the ability to integrate spatio-temporal information and such ability emerges by 5 month of age in human infants.
