The relationship between psychometric intelligence and rapid acoustic information processing was explored in two experiments using college students. Group differences occurred in threshold interstimulus intervals required for recognition and in speed. Results were interpreted as indicating better information processing efficiency (higher…

Suggests that the general ability structure for retardates is more complex than the structure for normals, containing a "stimulus trace" factor in addition to verbal-educational and spatial-perceptual parameters. (RL)

This study examines some relationships pertaining to socioeconomic status and cognitive ability patterns in fourth graders. Specifically, it explores the relative merits of Jensen's hierarchical theory of two levels of cognitive ability, in contrast to a process scheme, positing two parallel modes of coding information.

This report collects together three presentations given by the author at scientific and professional meetings during the Spring of 1977. The first discusses present views of the variety and complexity of individual differences among human beings in the context of current research on cognitive processing in learning and instruction. The second…

A study of twins was conducted to determine the presence of an hereditary component in short term memory and in three aspects of verbal divergent thinking--flexibility, fluency, and originality. Results showed the existence of a significant genetic component in the trait of short term memory, while none was found in verbal divergent thinking. (AG)

Recent studies are examined for methodological adequacy in establishing dimensions of individual differences in information-processing abilities, and the theoretical problems involved in inferring psychological processes from individual difference dimensions. Methodological inadequacies include use of small samples, questionable procedures in…

An approach to intelligence which emphasizes domain-specific constraints on knowledge structures is compared to information processing approaches. The evaluation of any cognitive ability as being intelligent crucially depends on prior specification of the formal constraints on the domains of knowledge from which that ability originates.

Reviews the influence of educational level on the intellectual performance of elderly individuals. Older individuals have more intellectual potential than previously has been reported. As cohorts receive greater educational opportunities, the negative stereotype of intellectual deterioration with age will no longer be accurate. (Author)

Detection differences between 16 mildly mentally retarded and 14 nonretarded students aged about 16 years were studied via the presentation of high, intermediate, and low stimulus organizations of target and distractor stimuli. Implications for explaining intelligence-related differences across a range of tasks are discussed. (SLD)

The assumption that a singular biological resource pool embedded in the central nervous system results in differences in macrolevel outcomes because of the constraints it imposes on efficiencies of microlevel processing is refuted. Moderating effects on the causal pathways between microlevel and macrolevel performance are discussed. (SLD)

Sternberg's theory of successful intelligence was used to create augmented exams in Advanced Placement Psychology and Statistics. Participants included 1895 high school students from 19 states and 56 schools throughout the U.S. The psychometric results support the validity of creating examinations that assess memory, analytical, creative, and…

Studies of recall and recognition short-term memory (STM) were reviewed, and a series of studies of serial recognition memory of normal and retarded children was described. In experiments using a recall procedure there were decrements in initial performance level with decreasing age and IQ but less evidence that forgetting occurred at a faster…

This article examines the potential contribution of latent trait models to the study of intelligence. Nontechnical introductions to both unidimensional and multidimensional latent trait models are given. Multidimensional latent trait models can be used to test alternative multiple component theories of test item processing. (Author/CTM)

Describes a new theory of multiple intelligences (MI) that identifies seven relatively independent forms of information processing that individuals exhibit in differing patterns. Describes the following MI-related educational research projects: (1) Arts PROPEL; (2) the Key School project; and (3) Project Spectrum. (FMW)
