The Effects of Several Confounding Variables on Color Vision Assessment in Young, Handicapped Children

Abstract

The possible effects of several confounding variables on color vision assessment was investigated with 75 mildi moderately mentally, retarded children ranging. in age I three to seven years. The s study, was an extension of a p study by Justen and Harth (1976). Support was obthined for the Justen and Harth conclusion that figure-ground perception may function as a confounding variable in color vision assessment. Other factors, including chronological age, cognitive ability level and visual-motor coordination, also appeared to be possible influences on color vision test performance of young midly to moderately mentally retarded children, implications for future research were briefly addressed.
