Two experiments were concerned with exploring the relative accessibility and availability of category information in retarded adolescents in comparison with CA equivalent nonretarded subjects. (Author/SB)

USING A CROSS-SECTIONAL SAMPLING PLAN, THE STABILITY OF WECHSLER INTELLIGENCE SCALE FOR CHILDREN (WISC) PROFILES, MEAN SCALE SCORES ON THE FOLLOWING SUBTESTS--INFORMATION, COMPREHENSION, ARITHMETIC, SIMILARITIES, VOCABULARY, AND DIGIT SPAN WAS EXAMINED AS A FUNCTION OF SEX, AGE, AND ABILITY LEVEL. FROM 167 WISC FORMS (OF BLIND BOYS AND GIRLS AGED…

The discriminative learning and transfer of compound and component problems were assessed in retarded subjects at two levels of intelligence. (Author/SB)

Compared the performance of 29 institutionalized cultural-familial mental retardates on Piagetian conservation tasks. Examined the effects of age, sex, and degree of retardation on conservation performance. (BD)

To learn if differences in age, intelligence, and sex account for differences in children's memory of TV commercials and "degree of insistence" (DI) after viewing them, 54 gifted, 71 normal, and 53 educable mentally retarded children (of both sexes, 7-13 years) were questioned. The mediating influence of the three independent variables on DI was…

Distinctions between psychological versus task helping and attempted versus achieved help were applied to the helping behaviors of normal and retarded children of 2 age groups observed in natural settings. (Authors)

The results of this study indicate that the basic components which underlie a major portion of the motor domain of intellectually normal and educable retarded boys are tangibly coincident. (RC)

The relation of CA, MA, and IQ to conservation was examined by comparing the performance of bright, normal, and retarded children matched on the critical MA of six years. (Author)

Results were interpreted as supporting an inhibition deficit theory of mental retardation. (Authors)

Examined were the effects of chronological age and mental age on the understanding of logical rules by four subject groups (10- to 14-years-old): 10 average IQ Ss, 10 learning disabled Ss, 10 older educable retarded Ss and 10 younger educable retarded Ss. (Author/CL)

Retardates, primary students, and college students were given either a reversal or an intradimensional shift after either a criterion of five or twenty correct on a pre-transfer problem. An automated two-choice apparatus projected planometric color and form cues from the rear onto panels that the subject was instructed to press. Both the…

Two studies are reported. The first is based on Piaget's assertion that the child's representation of his world is dependent on the level of cognitive development at which he is currently functioning. Forty-eight normals and 48 retardates were given a visual memory task. They were asked to recall a configural presentation in a number of ways,…

This research is, in part, a study of a method of differentiating between two different types of retardation (the exogenous or brain injured and the endogenous or non-brain injured). However, this paper is also an example of the evaluation of a research problem, for it incorporates data and information from three different studies, each of which…

This extensively annotated bibliography supplements an article by Zana Stein and Mervyn Susser entitled "Mutability of Intelligence and Epidemiology of Mild Mental Retardation," appearing in "Review of Educational Research," Volume 40, Number 1, February 1970, pages 29-67. Resource materials listed focus on: the fate of…
