Abstract

Administered a battery of tests for assessing visual responsiveness to 69 pigtail monkeys 2 days to 6 mo of age. Age changes were found on all tests. None of the responses could be consistently elicited at birth. Tests involving simple sensory capacities and orienting motor responses generally appeared first. Tasks requiring more complicated sensory processing or motor responses emerged at progressively older ages. By 5 wks after birth, normal Ss ordinarily responded positively on all tests. The battery is therefore a convenient and effective screening tool for assessing whether a young monkey has normal vision. Age norms are presented in terms of the percent of Ss at each age expected to respond positively on each test. Results are compared to the development of analogous responses in human infants.
