Major tenets summarizing Jensen's two-level theory of mental abilities were examined in a static-group comparison, correlational study. Caucasian siblings in grades one through four from low- and middle-socioeconomic (SES) populations were administered five Level I (associative learning ability) tasks and Raven's Progressive Matrices. Consistent…

A stratified random sample of 70 pupils was selected from 261 children from three elementary schools, who had completed one year of formal reading instruction. To investigate whether visual discrimination or visual-motor development was more closely related to reading achievement, tests of reading achievement, intelligence, visual-motor abilities,…

This report summarizes a research program in modeling human communication ability. The methodology involved selecting a single, naturally occurring dialogue, instructing a human observer to extract certain aspects relative to its comprehension, and then using these aspects to guide the construction and verification of the model. The model assumes…

This report is part of ongoing research engaged in transforming knowledge of how human communication works into improvements in man-machine communication of existing and planned computer systems. The methodology includes having a trained "Observer" annotate transcripts of human communication in a prescribed manner. One of the issues,…

Reported are the results of a series of studies conducted to identify the possible correlates of perceptual curiosity in retarded and normal IQ Ss (13-21 years old), and to determine the modifiability of perceptual curiosity in mentally retarded Ss through training and the possible transfer effects of such training. In a section on general…

Examines the IQs of 75 preschool children perceived to be "at risk" by parents, teachers, and diagnostic nursery staff. Full Scale, Verbal and Performance IQs were correlated with: (a) assessment of problem area (b) socioeconomic and familial variables (c) gross assessments of speech and motor development and (d) improvement in a special preschool…

The results of this study indicate that the basic components which underlie a major portion of the motor domain of intellectually normal and educable retarded boys are tangibly coincident. (RC)

The results of this study indicate that for school age children, changes in the family environment may be associated with relatively modest increments in performance scores. (RC)

The author defends I.Q. tests as being beneficial to students from low-income homes against detractors who insist the tests are hopelessly biased by social class and, hence, are useless. (HMV)

Mean response times and slope of response times were correlated with intelligence and achievement for 94 sixth-graders. Mean response time reliability was greater than that of slope, and correlated significantly with IQ and achievement. Speed of processing information generalized across experimental tasks and reliably indicated intellectual…

Tasks graded in terms of fluency, flexibility, originality, and elaboration of responses were administered to fourth graders in order to identify relationships between these measures of creativity, intelligence, and evaluation skills. With intelligence controlled, the relationship between creative thinking scores and evaluation ability was near…

Ten young males (aged 16-to-22 years) whose IQ scores ranged from 51 to 77 were compared on a simple discrimination task with ten male university students (aged 18-to-23 years) and 28 nonretarded male children (aged 7-to-11 years) in order to determine if reaction time is a consequence of mental retardation.

Hoffman won his case on the basis of being misclassified, placed in a school for the mentally retarded, and thus deprived of 12 years of learning opportunities. School officials are appealing on the grounds that damages are excessive and that the adminstration of an IQ test contraindicates malpractice. (WI)

Intelligence testing has a place in assessment and placement procedures. (PHR)
