Person-Clusters of Intellectually Normal and Educable Mentally Retarded Boys on Selected Motor Performance Variables.
Dobbins, D. Alan
This study assesses, via the description of a performance typology, that portion of a sample of educable retarded boys whose profiles over four factor-defined components of the motor domain resemble those profiles subtended by intellectually normal boys over the same four components. Tryon's Condensation Method was used to develop person-clusters for 71 educable mentally retarded boys and 71 boys of normal intelligence for four main performance components: (a) strength/power/body size, (b) gross body coordination, (c) fine motor abilities, and (d) balance. This multivariate approach allows the comparison of performance capabilities simultaneously over the many recognized components of the motor domain and the assessment of that portion of a retarded sample whose subtended performance profiles resemble those of the intellectually normal. Results indicate that while there exist marked differences between the performance profiles of educable retarded and intellectually normal boys, the motor abilities of about one-quarter of the educable retarded boys were no different from those of the majority of intellectually normal boys.
