Psychophysical study of efficiency of magnocellular and parvocellular systems with pre-school children in norm and pathology
The article is devoted to studying of the influence of magnocellular and parvocellular visual processing on the perception and apperception in children of pre-school age with normal and atypical development of different aetiology. It is shown that deficit of the visual magnocellular processing are characteristics of children with autistic disorders and children with mental retardation. The stronger this deficit is, the more pronounced the speech deviation is.
