  • Title: Prediction of retarded adults' work performance through components of general ability.
    Author: Schreiner J.
    Journal: Am J Ment Defic; 1978 Jul; 83(1):77-9. PubMed ID: 677182.
    Abstract:
    A factor analysis was performed on a set of variables used to predict work performance, or industrial rate, for 127 mentally retarded adults. The results indicated that there is a general ability factor that can be partitioned into three components: cognitive, visual-motor, and work sample/sorting abilities. The latter two components were more closely related to industrial rate than was the former. Variables included subject characteristics, standardized tests, ratings, and work samples. As a group, the work samples were the best predictors of industrial rate; the subject characteristics were the poorest.
