| summary | We use a developmental strategy to study the neural mecha-nisms underlying perception. Infants see poorly. Given nor-mal visual experience, vision develops to adult levels over months or years after birth. By comparing behavioral and neural changes during development we seek to identify the mechanisms that limit perceptual performance. In this talk, I will describe behavioral and neurophysiological studies of the development of form and motion perception in macaque monkeys. We have identified immaturities in the early vis-ual pathways – from the LGN through MT – in young animals that reflect some aspects of sensitivity as measured behav-iorally. However, these immaturities are not sufficient to explain the poor visual performance of infants. Therefore, we suggest that there are additional sites downstream in the visual pathways that impose limits on perceptual devel-opment. |
