Seventeen mildly retarded adolescents who participated in an Instrumental Enrichment program which stresses cognitive and metacognitive processes demonstrated significant gains in measured IQ following intervention and at a 6-month followup. Control Ss maintained or declined in intelligence level. (CL)

The article mentions six basic statements about sequential and simultaneous processes which are derived from A. Luria's clinical research. The Kaufman Assessment Battery for Children is then judged in terms of these statements. Suggestions for constructing tests which will entail planning as well as simultaneous and successive measures are…

Uses data from earlier study by Hollender to estimate mental ages for four quartiles of intelligence for a seven-year span (ages 12-18). Comparison of four groups at some mental age with groups where age or grade is held constant, regarding realistic vocational choices, suggests that mental age concept might be more meaningful than intelligence in…

It is suggested that the study of artificial intelligence can provide ways of thinking about the human mind that are potentially valuable in formulating cognitive theories. Theoretical psychology is proposed as an appropriate classification for this branch of theory. (MSE)

Cluster analysis, applied to Carroll's cognitive theory, indicates that the obtained clusters make intuitive sense and imply that taxonomy is possible. Moreover, some clusters are similar to those suggested by other theories, especially the theory of fluid and crystallized intelligence. (Author/CP)

Explores how new, operational models of cognition processing developed in Artificial Intelligence (AI) can be applied in computer assisted instruction (CAI) systems. CAI systems are surveyed in terms of their goals and formalisms, and a model for the development of a tutorial CAI system for algebra problem solving is introduced. (Author)

The first purpose of this editorial is to indicate a parallel trend in two disparate areas of research: information processing and cognitive-behavior modification (CBM). The second purpose is to highlight the role that affect plays in intellectual functioning, noting implications following the assessment of intelligence. (Author/RD)

Examined the effects of premature birth on ninety 11-year-olds' memory and processing speed, using the new Cognitive Abilities Test (CAT). Found that preterm subjects performed more poorly than their full-term counterparts on all CAT memory tasks, and that preterms were also slower on selected aspects of processing speed but not on motor speed.…

Age related declines in fluid intelligence were accounted for by age-related declines in a general latency factor (cognitive speed) for 63 adults aged 26 to 80 years, but results called into question the assumption that cognitive speed accounts for all individual IQ differences. (SLD)

The mental representations and processes used in verbal comprehension were studied in 2 preliminary studies and 2 experiments involving a total of 158 college students solving synonym or sentence completion tasks. Response choices and latencies could be predicted with explicit information-processing models. Implications for theories of…

A study of eight normal right-handed men demonstrates widespread significant decreases in brain glucose metabolic rate (GMR) following learning a complex computer task, a computer game. Correlations between magnitude of GMR change and intelligence scores are also demonstrated. (SLD)

This study found that 10 adolescents with mental retardation processed stimuli varying with respect to symmetry in comparable manner to peers matched for mental age and chronological age. Results argue for the robustness of the symmetry effect across groups differing in intelligence and physically dissimilar stimulus types (checkerboard versus…

J.H. Kranzler and A.R. Jensen report on a reanalysis of previous data that is again inconsistent with the hypothesis that psychometric "g" is unitary. J.B. Carroll reiterates objections to the evidence that Kranzler and Jensen offer in support of a composite "g." (SLD)

The mental processes underlying everyday predictive and postdictive judgments about objects undergoing change or no change were studied with 40 adults. Results supported a single information processing model for describing performance on both prediction and postdiction problems. The implications of the study of everyday inductive reasoning are…
