Abstract: | One approach to the understanding of intelligence is through research with retarded children and adults. Any characterization of the way(s) in which they differ from nonretarded individuals results in a specification of important components of intelligence. In this paper, we deal with two general areas of research. In one, centering on the role of control processes in memory and problem-solving situations, we argue that research with the retarded has succeeded in identifying a major component of intelligence. The results from a large number of experiments lead us to the conclusion that a hallmark of intelligence is the ability to generalize information from one situation to another, and that this ability in turn depends upon effective “executive control.” In areas where less research with retarded individuals has been doen, we suggest that comparative/developmental work is necessary to gain a better understanding of the processes in question. We illustrate this point by discussing some work aimed at locating individual differences in parameters representing basic components of general information-processing systems. |
