Although the accuracy of the diagnosis of cognitive impairment in the elderly depends on the appropriateness of the norms for the neuropsychological tests used, the importance of examining health status, native intelligence, and gender when attempting to describe cognitive changes of aging has received little attention. The Rey Auditory Verbal…

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.…

Reports the use of a memory load-interference paradigm and the easy-to-hard paradigm as converging operations to study capacity limitations in five- to six-year-old's reasoning. Concludes that transitive inference ability in children is capacity limited. (HOD)

The Cognitive Levels Test (CLT) and the Peabody Picture Vocabulary Test-Revised (PPVT-R) were administered to 30 freshman college students at a small state college in the mid-Atlantic region. Significant correlations indicate that the PPVT-R measures a component of the CLT. Mean PPVT-R scores were significantly higher than CLT means. (Author/PB)

Describes early research examining the validity of the original Inventory of Learning Processes. Presents a revised version of the inventory with reliability and validity data. Discusses reflective and agentic processing as the two major routes to academic achievement. Concludes that the smooth flow of cognition depends on the student's…

The Cognitive Levels Test, for use with ages 5-21, is designed as a quick cognitive assessment instrument with 4 subdomains: verbal reasoning, abstract reasoning, quantitative reasoning, and memory. This paper describes the test's administration, summation of data, standardization, reliability, and validity. (JDD)

The Stanford Binet Intelligence Scale measures four areas of cognitive abilities (verbal reasoning, abstract/visual reasoning, quantitative reasoning, and short-term memory), providing a continuous scale for appraising cognitive development from age two to adult. This paper describes the test's administration, standardization, reliability, and…

Proposes a theory of cognitive processes in doing and learning place value arithmetic. Discusses a computer model that simulates the learning of multicolumn subtraction under one-on-one tutoring to measure the relative difficulty of two methods of subtraction. The model predicts that regrouping is more difficult to learn than an alternative…

Gender differences in level and pattern of cognitive abilities were examined in 49 learning-disabled college students. Females were stronger in visual-motor abilities and verbal conceptualization, whereas the males' highest abilities were nonverbal visual-spatial. Both groups showed weaknesses in memory for digits and factual knowledge and in…

Evidence from the research literature suggests that a variety of cognitive factors are responsible for chemistry achievement. This investigation examined the role that four cognitive factors, namely, prior knowledge, formal reasoning ability, memory capacity and field independence/dependence, play on achievement in chemistry as measured by tests…
