Associative Grouping Strategies Among Educable Mentally Retarded and Normal Boys.
Herzog, Beverly Henson
An information processing model was used to examine the organization of stimulus information during the input process among educable mentally retarded (EMR) and normal boys. Three groups of subjects (Ss) were matched on socio-economic status and race--a group of EMR boys, a group of normal boys matched with the EMR Ss on chronological age (CA normal group), and a group of normal boys matched with the EMR Ss on mental age (MA normal group). Each group was subdivided into two age groups. The older subgroups received three grouping tasks--objects, pictures, and words. The younger subgroups received two grouping tasks--objects and pictures. The responses of the Ss were coded into grouping strategy categories--superordinate, complexive, or thematic. As hypothesized, the results revealed that EMR Ss used fewer superordinate strategies than either equal CA normal Ss or equal MA normal Ss. No differences were found in the effects of age on performance of EMR and equal CA normal Ss. Neither were differential effects of stimulus materials evidenced in the results. Differences found in the performance of normal and EMR Ss were related to findings of other studies of cognitive abilities among EMR Ss. Partial support was found for the hypothesis that increasing numbers of stimuli decrease the use of efficient grouping strategies among EMR subjects. (AMM)
