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)

Discusses work by Arthur Jensen in addition to his well-known work on the genetics of intelligence. Includes studies of learning, memory, the cumulative-deficit hypothesis, Spearman's hypothesis, and the speed of information processing. (SLD)

The possibility that the ability measure activation savings is related to practiced skill, not because of cognitive overlap, but because of the proximity of savings' measurement to measurement of practiced skill was assessed with 404 military trainees. Implications for individual difference research of test-proximity effects are discussed. (SLD)

College undergraduates learned word lists involving three-term contingencies (stimulus-response-outcome). Learning rate was correlated approximately 0.5 with scores on Raven's Advanced Progressive Matrices (Raven) but did not correlate significantly with several tasks (inspection time, card-sorting, trail-making, PASAT) shown to be associated with…

Comments on the work of Arthur Jensen, specifically "The g Factor" (1998), which consolidates the psychometric, neurophysiological, behavior genetic, and comparative evidence for the existence and importance of a factor of general intelligence ("g"). Discusses Jensen's work on black/white differences in intelligence. (SLD)
