This study in the Northern Nigerian educational system tested the hypothesis of British and American studies that academic achievement at primary school is positively associated with extraversion. Contrary to previous studies, the results of this inquiry yielded a significant negative association between extraversion and academic attainment.…

Given the number and variety of components underlying performance in two clusters of tests, i.e., embedded-figures and adjustment tests, an understanding of the high-order construct field dependence and of its relationship to other cognitive, personality, and performance dimensions requires the execution of comprehensive studies.

The Life Complexity Inventory was designed and administered to 140 adults in order to investigate those variables present in their day to day experience that might relate either to stability or decline of intellectual ability. Results suggest that individuals with similar life styles display similar ability patterns over time. (Author/GC)

Limitations of current information-processing research on the nature of intelligence are discussed. Major criticisms are that the tasks are static; lack of generalizability from the laboratory to the real world; and collective intellect, motives, goals, circumstances, and ambiguity are not addressed in either theory or research. (Author/RD)

Based on a study which controlled for the effects of age, sex, maritial disruption, socioeconomic status, race, and other potentially confounding variables, this article explores the theoretical validity of the confluence model in explaining the effects of sibship size and birth order on intelligence. (Author/GC)

Tailored testing by Cliff's method of implied orders was simulated through the use of responses gathered during conventional administration of the Stanford-Binet Intelligence Scale. Tailoring eliminated approximately half the responses with only modest decreases in score reliability. (Author/BW)

The adaptive behaviors measured by Part I of the Adaptive Behavior Scale (ABS) showed relatively large associations with IQ. In contrast, Part II domains, which deal primarily with conduct disorders, showed low to negligible associations with IQ. (Author)

A study to develop a short form of the Wechsler Intelligence Scale for Children-Revised (WISC-R) for the intellectually gifted showed the Vocabulary and Block Design comprise the best two-subtest short form. The Similarities, Vocabulary, Block Design, and Object Assembly tetrad could be most useful in time and reliability. (Author)

Criteria were developed to assess sexual and racial item content bias for every item from six IQ tests. Each reference was judged as either stereotyped or not sterotyped. This analysis pointed out an overwhelming sexual and racial imbalance in item content. (Author/RL)

Examines the case of Nadia, an autistic child with unusual graphic ability. Considers the development of her skill in relation to hypotheses about drawing, intelligence, and conceptual thought. Illustrations are included. Commentaries on this article by Charles Cleland and Martin Rayala appear on pages 68-72 of this issue. (SJL)

Evaluates diagnostic utility of Bannatyne's recategorized WISC-R scores in differentiating among children referred to a developmental evaluation center. Results failed to provide support for the diagnostic utility of recategorized WISC-R scores in general. Use of measure is limited in differentiating psychological and learning problems. (Author/CJ)

Intake placement data were collected from the files of 1,966 students labeled and served as learning disabled in Child Service Demonstration Centers (CSDC) in 22 states. There appeared to be a lack of consistency in the characteristics of students labeled learning disabled. (Author)

The intelligence test performance of 24 acoustically handicapped students (6 to 15 years old) applying for enrollment in a state school for the deaf during a 7-month period was analyzed. Data confirmed the need for such schools to maintain strong academic programs to meet the total needs of the bright, deaf child. (Author/CL)

A longitudinal study of 26 mathematically gifted and 26 high IQ boys (11 to 14 years old) and their families focused on parents' and grandparents' educational attainment, parents' and Ss' birth order, Ss' and parents' creative potential, and Ss' cognitive giftedness. (SBH)
