| Research Abstract |
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.
