摘要
Two relevant dimensions are revealed within which developmental patterns of perceptual organization might be investigated. Within the local-integrative dimension, employing a contour integration task, we found indications that spatial integration develops slowly. We also found reduced contextual modulation of a local target in children employing the Ebbinghaus illusion. Within the action-perception dimension, we hypothesize a relatively slow development of the perceptual system (mediated by the ventral visual stream), as compared to the development of the action system (mediated by the dorsal visual stream). Taken together, the data indicate that long-range neuronal connectivity supporting perceptual organization in the posterior pole of the brain, and in the ventral visual pathway is not fully developed in young children.
