Colour Discrimination in Mentally Handicapped Children with Particular Reference to Down's Syndrome

Abstract

This investigation considers differences between young non-disabled children and mentally handicapped children in their discrimination of colour. Though the concept of colour differences may be intact in these children, their verbal language does not always correspond. The results of this experiment demonstrate that Down's Syndrome children are equal to non-disabled children, matched on mental age, in their ability to discriminate between colours. Both Down's Syndrome and non-disabled children make errors of the same kind. Other undifferentiated mentally handicapped children are less consistent in their colour discrimination behaviour.
