Prevalence rates of cognitive impairment in persons 75 to 85 years of age have been documented in the range of 10-15%, and exceeding 20% after age 85. A recent study has demonstrated even higher prevalence rates: 18.7% between the ages of 75-84 and 47% in persons over 85 years of age. Screening for dementia in persons 75 years of age and older…

Eighty-two children (ages 4.4 to 6.5 years) were administered a Backward Digit Span test to measure M-space and four conservation tasks (number, substance, continuous quantity, and weight). Based upon a neo-Piagetian theory of intellectual development proposed by Pascual-Leone (1969), two hypotheses were tested: (1) A significant relation should…

INDIVIDUAL DIFFERENCES IN RISK TAKING WERE STUDIED IN A SAMPLE OF 162 MIDDLE-CLASS CHILDREN IN GRADE 5. MEASURES OF ANXIETY, CREATIVITY, DEFENSIVENESS, INTELLIGENCE, AND RISK TAKING WERE ANALYZED TO DETERMINE CERTAIN SELECTED RELATIONSHIPS. THE AUTHOR CONCLUDED THAT CREATIVITY BEARS A MORE POWERFUL RELATIONSHIP TO RISK TAKING THAN DOES…

Discusses changes in testing as a result of the availability of extensive inexpensive computing and some recent developments in statistical test theory. Describes the role of the Computerized Adaptive Test (CAT) and modern Item Response Theory (IRT) in ability testing tailored to each student's knowledge and ability. (JAC)

The present study was designed to (1) investigate the changes in the structure and organization of mental abilities during childhood and adolescence of 514 students as sampled by the Wechsler Intelligence Scale for Children (5 to 15 years) and the Wechsler Adult Intelligence Scale (16 to 18 Years) and (2) interpret, and possibly modify, the…

Twenty-three high school biology students were individually administered three conservation tasks (weight, volume, volume displacement). During one semester, they were examined over the course material using published Biological Sciences Curriculum Study (BSCS) Blue Version examination questions which were previously classified as requiring either…

The present study was undertaken to assess whether training that was known to produce transfer within the Cognition of Figural Relations (CFR) domain of Guilford's Structure-of-Intellect model would also produce transfer to other operations in Guilford's model. Fifty subjects, matched for pretest score on a double classification task, were…

The text focuses on identification criteria and characteristics of gifted and talented students in the context of educational programming. The section on characteristics discusses kinds of intelligence, indicators of giftedness, student characteristics that may pose difficulties for the classroom teacher (e.g., persistence, criticalness, and…

New approaches to assessing intelligence are discussed, as well as new intelligence tests. Among the developments are investigating neurometrics, adapting testing to the effects of technology on children, countering cultural bias, assessing social intelligence, focusing on aspects of cognitive styles, measuring learning potential, and using…
