Prepared as part of a larger work on human intelligence, this report examines basic attentional and perceptual contributions to intelligence. The report is organized into two sections: the first summarizes and evaluates research that has tried to uncover basic information processing skills that account for individual differences in intelligence;…

Forty-three junior high learning disabilities programs were surveyed to identify students either specifically disabled in arithmetic (SLDARITH, N=30) or specifically disabled in reading (SLDREAD, N=30). Three types of data were analyzed: size of LD program and school, Wechsler Intelligence Scale for Children (WISC) Verbal and Performance scores,…

The cultural test bias hypothesis represents the contention that all ethnic or racial group differences on mental tests are due to inherent, artifactual biases produced within the tests through flawed psychometric methodology. This address focuses on an empirical evaluation of the cultural test bias hypothesis, especially emphasizing the construct…

The ACT theory of the learning of procedures is described. ACT is a computer simulation program that uses a propositional network to represent knowledge of general facts and a set of productions (condition action rules) to represent knowledge of procedures. There are currently four different mechanisms by which ACT can make additions and…

This report describes the principal findings and recommendations of a 2-year Rand research project on machine-aided knowledge acquisition and discusses the transfer of expertise from humans to machines, as well as the functions of planning, debugging, knowledge refinement, and autonomous machine learning. The relative advantages of humans and…

The study compares the performance of 50 fourth grade learning disabled students on the Wechsler Intelligence Scale for Children-Revised (WISC-R) and the Tests of Cognitive Abilities from the Woodcock-Johnson Psycho-Educational Battery (WJTCA). Results indicated that learning disabled Ss performed more poorly on the Tests of Cognitive Abilities…

Two studies were conducted to (1) analyze the subtest characteristics of the Woodcock-Johnson Psycho-Educational Battery, and (2) apply those results to an analysis of 50 fourth grade learning disabled (LD) students' performance on the Battery. Analyses indicated that the poorer performance of LD students on the Woodcock-Johnson Tests of Cognitive…

Eighty-one fourth grade students were administered tests, tasks, and observations to investigate the relationship between IQ, rates of learning, scores on standardized achievement tests, and results of classroom observation. There was a substantial relationship between IQ, standardized tests, and rates of learning, but not classroom observation.…

The importance of validity and reliability in the componential analysis of human intelligence is discussed. The roles of construct, internal, external, convergent, discriminant, and ecological validity in componential analysis are outlined. Within-replication (internal-consistency) and between-replication (alternate-forms or test-retest)…

A study involving 59 undergraduate speech communication students investigated relationships between intelligence, understanding of editorial satire, and appreciation of satire. The students were asked to read three satirical essays and then to pick one of five statements that best described the thesis as intended by the author. Then each satire…
