     Abnormal visual experience has been shown to lead to abnormal development of the neural visual system. This session will go beyond classical work in early cortex to explore the effects of abnormal experience at later stages of processing. It will also address surprising recent insights into manipulation of experience in treatment, both during and beyond the traditional critical period.

Abstract

Many visual functions are poor in infant primates and develop to adult levels during the early months and years after birth. Basic visual processes and those that are higher-order develop over different time courses, with higher-order abilities developing over longer slower time courses. These later developing aspects of vision are those that require the integration of information over space (such as contour integration) or space-time (such as global motion or pattern motion discrimination), and likely depend at least in part on the maturation of extrastriate visual areas. Moreover, these developmental programs can be modified by visual experience, with the later developing functions showing greater vulnerability to abnormal visual experience. This talk will describe the development of global form and motion perception, highlight the influence of abnormal visual experience and discuss underlying neural correlates.
