Perceptual, Conceptual, and Psycholinguistic Evaluation of the Mentally Retarded Child

OuR primary concern in the tests discussed in this chapter is with function rather than with classification alone. According to Gelof ( 1963), mental retardation is a "deficit in functioning which handicaps certain people in our verbal, technological society" (p. 298). This is the deficit, or more likely deficits, that the psychologist should evaluate.
