Cognitive Development Among Retardates: Reanalysis of Inhelder's Data.
Jordan, Valerie Barnes
A reanalysis of B. Inhelder's (1968) data concerning cognitive development among retardates was performed by selecting from the original 159 subjects a sample of 104 educable mentally retarded Ss (7-19 years old) who were diagnosed as fixated or nonfixated at three of the cognitive stages postulated by Jean Piaget. The results indicated that among fixated retardates, those at lower cognitive stages differed significantly in IQ and MA, while those at higher cognitive stages differed significantly in CA and MA. Among nonfixated subjects, differences between those at each cognitive stage were significant on CA and MA, but not on IQ. In contrast to fixated subjects, nonfixated subjects had significantly higher IQs and MA, and reached higher cognitive stages. It was concluded that a diagnosis of cognitive fixation seemed premature for preadolescent retardates, since the potential for cognitive growth through adolescence appeared strong. (LS)
