Classification of abnormal children: Discrimination learning ability

Journal of Autism and Developmental Disorders, 1980
Large individual differences exist among psychotic and retarded children, and a procedure that would enable classification of discrimination learning ability would be of value. A procedure designed to assess the discrimination learning thresholds of low-functioning children is described. A performance index (PI) that reflects accuracy of discriminative

Field-Dependence and Color Discrimination Ability in Females

Perceptual and Motor Skills, 1983
Previous research has shown that field-independent males are very superior to field-dependent males in ability to discriminate colors. The research reported here examined the same relationship with females. 30 females were tested twice on the Farnsworth-Munsell 100-Hue Test.
