Test Response Patterns which Differentiate between Two Levels of Behavior of Mentally Retarded Children. Final Report.
Boswell, James D.
The interrelations between mental age (MA), IQ, and mediation were studied in 72 retardates in special classes. Subjects were selected to fall into sexually balanced groups of six in 12 MA-IQ categories (IQ 50-59, 60-69, 70-79, and 80-89; MA 4-0 to 5-11, 6-0 to 7-11, and 8-0 to 9-11). The apparatus alternately displayed two pairs of stimuli, and three series of trials were run without interruption between them. Series 1 required discrimination, series 2 required discrimination reversal, and series 3 tested for mediation, or reversal. Although significance was not achieved in analyses of total number of reversal shift responses or of number of subjects achieving a reversal shift, there was a significant increase in both number of mediational responses and number of mediators between IQ levels 50-69 and 70-90. The two IQ levels also varied significantly in both cases. Significance was not found with respect to any levels of the MA variable. Results on series 1 and 2 showed significantly better performance within MA group with increasing MA: on series 2, the performance of nonreversers was significantly better. Thus, mediation did not increase with increasing MA, but did increase with increasing IQ. (JD)
