It was concluded that while retinoblastoma per se is not associated with intellectual superiority or inferiority, retinoblastoma associated with blindness may result in selective cognitive superiority. (Authors)

Analysis of the mental factors of seventh grade students indicates that numerical facility and perceptual speed are a single factor at this age level and that no purely verbal factor exists. Seven clearly differentiated factors are found for males and five for females. (Author/WY)

This paper presents a description of four schools of thought on the nature of intelligence, some findings that have emerged from them, and an indication of how these findings reveal a common core of generalizations across the various schools. (Author/SJL)

Results of a study involving 15 mentally retarded and 15 nonretarded control subjects matched for mental age suggest that some low-level aspects of person-related (and probably object-related) perception may not involve the same high-level symbolic functions typically employed in intelligence-quotient related functions. (SLD)

Compared to children with high-average and low-average intelligence quotients, 26 intermediate grade gifted children used fewer moves to solve a combinatorial problem-solving task and exhibited higher metacognitive knowledge on person and strategy variables. Qualitatively different intercorrelational patterns among problem-solving, metacognition,…

This paper summarizes empirical findings of research on a theory of general mental ability, based on laboratory studies of the relationship between measurements of individual differences on conventional psychometric tests and in speed and efficiency of information processes. The paper covers characteristics of "g" (general mental ability),…

The relationship between speed of information processing (SIP) and psychometric intelligence was investigated by giving 60 college students (22 males and 38 females) 2 choice reaction time (RT) tests (modified Hick paradigm) and Raven's Advanced Progressive Matrices. Results support an association between intelligence and SIP. (SLD)

This paper describes the development and empirical investigation of two new paper-and-pencil measures of elementary cognitive tasks (PP ECTs). In three empirical studies involving 333 adults, the PP ECTs proved reliable. They were substantially correlated with other measures of psychometric intelligence and they displayed convergent validity with…

In this mixed methodology study, the researcher became the research practitioner through Educational Action Research. His personal practice of training adult Bible teachers was examined by measuring the self-perceived changes of a group of adult Bible teachers as they were trained to change from their traditional mode of primarily teaching the…

We examined whether very preterm ([less than or equal to] 30 weeks gestation) children at early school age have impairments in executive function (EF) independent of IQ and processing speed, and whether demographic and neonatal risk factors were associated with EF impairments. A consecutive sample of 50 children (27 boys and 23 girls) born very…

This study determined which intellectual abilities account for IQ changes over the school year. All the Head Start subjects involved in the study (35 boys and 33 girls, mean age 44.1 months) lived in poverty under conditions of urban deterioration. The subjects were initially given the Standord-Binet Intelligence Scale in the fall and were tested…

Current studies of cognition emphasize the contrast between two approaches to analysis of individual differences. It is concluded that the cognitive components approach incorporates the cognitive correlates approach, avoids the inadequacy of correlational methods, and models individual differences on various dimensions of cognitive functioning.…

Artificial Intelligence researchers and cognitive scientists commonly believe that thinking involves manipulating representations. Thinking involves search, inference, and making choices. This is how we model reasoning and what goes on in the brain is similar. Winograd and Flores present a radically different view, claiming that our knowledge is…

Determined if Wechsler Intelligence Scale for Children-Revised subtest patterns would differentiate the performance of emotionally disturbed and learning-disabled children. Subtests differentiated significantly between diagnostic categories. Learning-disabled children performed predictively poorer on block design, picture arrangement, and object…
