EARLY DEVELOPMENT OF VISUAL ABILITIES

摘要

In this paper I argue for a developmental view of some of the basic visual processes in humans. The support provided for this position comes from a variety of sources. There are results from psychological, anthropological, and neuro-physiological studies here reviewed, that show how even certain low-level visual processes depend on environmental-driven learning. In addition, a neurocom-putational model of the lower visual pathway in the cortex is provided that replicates features of two main visual processing functions: orientation selectivity in VI (primary visual cortex) and corner selectivity in V2 (secondary visual cortex). These functions emerge in the model purely by exposure to stimuli.
