This study used structural equation modeling to examine the effect of Stratum III (i.e., general intelligence) and Stratum II (i.e., Comprehension-Knowledge, Fluid Reasoning, Short-Term Memory, Processing Speed, and Visual Processing) factors of the Cattell-Horn-Carroll (CHC) cognitive abilities, as operationalized by the Wechsler Intelligence…

To explore possible reasons for low self-identification rates among undergraduates with learning disabilities (LD), we asked students (38 with LD, 100 without LD) attending two large, public, research-intensive universities to respond to a questionnaire designed to assess stereotypes about individuals with LD and conceptions of ability. Responses…

Owing to higher performance on the Raven's Progressive Matrices (RPM) than on the Wechsler Intelligence Scales (WIS), it has recently been argued that intelligence is underestimated in autism. This study examined RPM and WIS IQs in 48 individuals with autism, a mixed clinical (n = 28) and a neurotypical (n = 25) control group. Average RPM IQ was…

The purpose of the present research was to investigate the difference in depression between intellectually gifted and non-gifted secondary school children. After a detailed review of literature the following hypothesis was formulated; there would be a significant difference between intellectually gifted and non-gifted secondary school children on…

Specific training may be required to develop creativity in design students. At the very least, training is valuable in developing creativity in first-year students. Creativity is a skill that can be examined, used and taught--and it is one that is central to designing. This paper presents the results of empirical research from a class in creative…

Discusses shortcomings of the WISC-III while noting that overall, there are substantial improvements in the WISC-III over the WISC-R. (KW)

Forty children were divided into four groups and administered the Tower of Hanoi puzzle using static and dynamic approaches. The benefits of age and ability were indicated by significant improvement from the general failure of the four- to five-year olds to the success of the majority of the high ability seven- to eight-year olds.

A meta-analysis of 50 studies was conducted to investigate whether juvenile delinquents use lower levels of moral judgment than their nondelinquent age-mates and, if so, what factors may influence or moderate the developmental delay. The results show a lower stage of moral judgment for juvenile delinquents (d = 0.76). Effect sizes were large for…
