Specifying the effect of visual deprivation on the rat's ability to recognize patterns


, : Specifying the effect of visual deprivation on the rat's ability to recognize patterns. Canadian Journal of Psychology 36(3): 488-496

The performances of light-reared and dark-reared rats were compared on a variety of transfer tests following acquisition of a visual discrimination in which the critical difference between the patterns was the type of intersection or junction between lines. Significant difference due to rearing were observed in the initial rate at which the discrimination was acquired and, following 15 day of overtraining, on a subsequent series of transfer tests. Apparently, the spatial integration necessary to recognize even as basic a relationship between linear elements as angle or junction involves mechanisms which require experience for their development and maintenance.
