Results bolster confidence in Crockett's standard two-peer Role Category Questionnaire (RCQ) as a measure of cognitive complexity (construct differentiation). Satisfactorily high four-week test-retest reliability estimates were obtained for differentiation measures based either on timed or untimed versions of the RCQ. Moreover, both versions…

Investigates intellectual differences among high-fit young and old and low-fit young and old adult men before and after an exercise program. It is not clear from this study whether improvement in cognitive functioning with exercise is due to physiological or psychological changes or both. (Author/CC)

Prior studies found individual differences in visual recognition memory during infancy were related to individual differences in later intelligence. This paper discusses methodological issues in the measurement of infant visual recognition, the significance of previously obtained predictive validity coefficients, and the theoretical question of…

Residents (N=27) of a Jewish home for the aged were given a battery of 25 tests of cognitive abilities. There were marked individual differences among participants. Poorer performance was associated with carrying a diagnosis of organic brain syndrome and with a number of other background variables. (Author)

Wechsler Intelligence Scale for Children-Revised (WISC-R) test-retest data with a six-month interval were obtained for 45 normal l0-year-old children. Verbal IQ estimates were stable, but significant practice effects were obtained on performance and full scale IQ estimates. Discussion focused on test readministration. (Author/RL)

The Interactive Learning Model illustrates how we process information (cognition), perform learning tasks (conation), and develop a self when performing difficult learning tasks (affectation). Individuals approach learning tasks with varying degrees of sequence, precision, technical reasoning, and confluence. These ingredients are embedded in the…

Attempted to clarify whether fear is related to distorted cognitive processing of fear-related information. Administered card and single-trial formats of Stroop task to spider-fearing and control children. Found bias for spider words in both, regardless of format; further, processing biases assessed by the formats did not correlate, suggesting…

Describes a study that analyzed the Educational Testing Service's (ETS) Tasks in Critical Thinking as a measure of college student critical thinking skills. Reports that difficulty levels of the Tasks and Skills were not consistent--overall, the number of general education courses taken did not affect student performance on the task, and students'…

Recent decades have seen major changes in measurements of cognitive ability and interpretation of results. Theory describing the factorial structure of cognitive ability has blossomed. Advances in psychometric and statistical tools available to test developers have facilitated application of better theory to new assessment instruments.(SM)

The study provides descriptive data on use of the Woodcock-Johnson Tests of Cognitive Ability with 39 adults with closed head injury. Correlational analyses indicated significant relationships between coma duration and performance on the Perceptual Speed and Memory clusters of the test. Time since injury did not correlate with test results.…

Discusses the problems of using chronometric analysis, a common cognitive psychological method, for educational assessment. Suggests that cognitive assessment has not reached the precision needed to analyze individual differences. (FMW)

Caregivers (N=53) of dementia patients administered modified version of cognitive examination at home to their patients. Comparison between caregiver-administered and clinical examinations revealed high interrater reliability unaffected by caregiver age or education level. Reliable assessment of cognitive functioning by caregivers can provide…

Responds to criticism of own research involving mental abilities testing of American Indians. Outlines and analyzes the author's systematic 10-year program of such research. Makes recommendations for future, tribally directed studies. Contains 31 references. (SV)

This study determines the comparability of the Wechsler Intelligence Scale for Children-Revised and the Wechsler Intelligence Scale for Children-III in relation to gifted children. Results indicate that both tests produce remarkably similar scale and subtest scores when administered under clinical conditions. (JPS)
