The purposes of this study were to investigate adolescent intellectual decline, and to attempt to determine some of the sexual differences possibly inherent in the phenomenon. It was hypothesized that (1) girls would decline in greater numbers and to a greater degree than boys; and (2) areas and amounts of sex differences of the decliners would…

Describes a method that uses age equivalents and standard scores to recreate the full range of variability in the scores of low-functioning individuals. The method allows for a more complete interpretation of performance that can lead to better educational and therapeutic programming. (Author/MCF)

Focuses on the difference in political efficacy found between black and white pre-adults. Suggests that the racial difference in feelings of political effectiveness is due to intelligence which, in turn, is basically a function of the social and economic environment. Suggests that intelligence may play a significant role in the political…

Analyses of 109 drug-abusing adolescents indicated that inhalant abusers performed significantly more poorly than polydrug abusers on 20 of 67 neuropsychological measures. Deficits were observed on both global (WAIS and WRAT) and specific measures (perception of speech sounds, visual suppression, sensory perception, and trails). (Author/SJL)

One hundred eighty-eight randomly selected case studies of adjudicated adolescents were analyzed to determine their intellectual levels and the scholastic achievement levels in reading and arithmetic. (CL)

This study investigated the self-reported fears and some personality characteristics of a sample of 1112 adolescents ranging in age from 12 to 18 years (attending grammar and secondary schools in Northern Ireland). (CS)

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)

Data suggest an ability to use concrete-operational reasoning is not required for doing complex arithmetic, even though it may be necessary for learning these arithmetic skills. (Authors)

Results indicated that retarded Ss, relative to normal Ss of all ages, responded particularly slowly to static property statements when objects were animate, and to intrinsic-action properties when objects were inanimate. (Author/DLS)

Factor analyzed Wechsler Intelligence Scale for Children-Revised scores of low-IQ youths aged 9-11 and 14-16. Extracted Verbal Comprehension, Perceptual Organization and Freedom From Distractibility dimensions for each group. Coefficients of congruence indicated the two age groups were not similar on the Freedom From Distractibility factor.…

All of the children were presented conservation of liquid and weight problems and 12 metaphor items. The results suggest that hearing loss did not affect the solution of either conservation or metaphor. (Author)

The Performance Scale of the Wechsler Adult Intelligence Scale-Revised was administered to 185 hearing-impaired young adults. A gender difference was found only on the Digit Symbol subtest, where females outperformed males. The high degree of factorial similarity between males and females indicated that the underlying construct being measured does…

A reanalysis of B. Inhelder's (1968) data concerning cognitive development among retardates was performed by selecting from the original 159 subjects a sample of 104 educable mentally retarded Ss (7-19 years old) who were diagnosed as fixated or nonfixated at three of the cognitive stages postulated by Jean Piaget. The results indicated that among…

The purpose of this study was to investigate the relationship between auditory discrimination, as measured by the Wepman Auditory Discrimination Test, and reading achievement, as measured by the Woodcock Reading Mastery Tests. After controlling for intelligence, there was little more than a random relationship between auditory discrimination and…
