A procedure to effectively and efficiently train moderately and severely retarded individuals to make fine visual discriminations is described. Results suggest that expectancies for such individuals are in need of examination. Implications for sheltered workshops, work activity centers and classrooms are discussed. [This article appeared…

Examined was the relationship between dependency behavior and learning in educable mentally retarded (EMR) children. Population included 120 subjects equally divided by sex into two groups of retardates and normals and subdivided into socially reinforced and non-reinforced Ss. The task measured overt or instrumental dependency (ID). Electronic…

Thirty-six retarded and 36 nonretarded children and adolescents, individually matched for mental age, were given discrimination problems at two levels of stimulus complexity to test the hypothesis that retarded persons require more trials to reach criterion on the more complex problems. (Author)

Sixty-four 8-year-old children were divided into fast and slow learner groups and trained on a tactile simultaneous discrimination task. Selective attention was measured in terms of percentage contact time per trial to the relevant dimension. Inter- and intracouplings per trial were also recorded. A multivariate analysis was carried out to examine…

The present investigation was conducted to determine if stimulus overselectivity in 19 autistic children (5 to 12 years old) is changed as a function of repeated exposure to testing. (Author/SBH)

Investigated was double responding as a technique which facilitates oddity discrimination under conditions of stimulus response discontiguity using three groups each with 12 educable mentally handicapped subjects (13.1 to 16.5 years). (Author/DB)

Sixty mentally retarded children (mean chronological age 19.4 years, mean mental age 5.2 years) were analyzed on their discrimination of 116 colored action pictures. (Author)
