This study provides the first direct evidence of cognitive continuity for multiple specific information processing abilities from infancy and toddlerhood to pre-adolescence, and provides support for the view that infant abilities form the basis of later childhood abilities. Data from a large sample of children (N = 131) were obtained at five…

Intelligence-related differences in perceptual processing in a global/local task were studied for 19 mentally retarded high school students and 19 nonretarded college students. Both groups processed global information faster than local information, and local naming practice caused increases in local processing time. (SLD)

Considers the contribution to information-processing accounts of human intelligence differences made by Arthur Jensen, commending his persistence in research and noting his reductionist orientation. Explores the question of correlated vectors studied by Jensen. (SLD)

Eighty gifted and 80 nongifted African American, Latino, Filipino, and white elementary school students were evaluated through information processing tasks. There were large differences on all four tasks, two depending on speed of processing and two not dependent on speed, as a function of grade and gifted program membership. (SLD)
