In three experiments, gender and ability (performance and emotional intelligence) related differences in brain activity--assessed with EEG methodology--while respondents were solving a spatial rotation tasks and identifying emotions in faces were investigated. The most robust gender related difference in brain activity was observed in the lower-2…

Although the Flynn Effect has been studied widely across cultural, geographic, and intellectual domains, and many explanatory theories have been proposed, little past research attention has been paid to subgroup differences. Rodgers and Wanstrom (2007) identified an aggregate-level Flynn Effect (FE) at each age between 5 and 13 in the Children of…

Two studies were conducted to identify individual differences in the effect of instruction on strategies used to solve figural/numerical analogies. The first study assessed students' use of an appropriate rule for solving analogies and the stimulus attributes they incorporated. In Study 2, verbal protocols of selected subjects were analyzed.…

Empirical data suggest that there is at most a very small sex difference in general mental ability, but men clearly perform better on visuospatial tasks while women clearly perform better on tests of verbal usage and perceptual speed. In this study, we integrated these overall findings with predictions based on the Verbal-Perceptual-Rotation (VPR)…

Working memory (WM) has been associated with the acquisition of arithmetic skills, however, the components of WM that underlie this acquisition have not been explored. This study explored the contribution of two WM systems (the phonological loop and the central executive) to mathematical performance in young children. The results showed that a…

Individual differences in the ability to connect thoughts to emotions were studied with 321 participants who read the writings of a target group and guessed the emotions of targets. Findings are interpreted to mean that some forms of emotional problem solving require emotional openness as well as general intelligence. (SLD)

Research on educable retarded children is reviewed to explicate components of and a theory of intelligence. Studies of control processes in memory and problem solving indicate that the ability to generalize is a major component of intelligence. Research on individual differences in components of information processing systems are also discussed.…

Sex differences in speed of solving mental rotation problems were replicated but college men and women were alike in frequency of use of algorithms to solve problems. The most frequent algorithm involved encoding stimuli in working memory, mental rotation of one to orientation of the other, comparison, and response. (Author/RD)

A large sample of 11-year-olds were observed on a perceptual maze task. Three ability level groups were formed and compared as to overall response paths and specific binary decision configurations. Explanations for observed qualitative differences and discussion of the viability of the experimental approach adopted are presented. (Author/RD)

The hypothesis that coping with novelty is a key aspect of intelligence is not supported by the data of Sternberg and Gastel. It is contended that these authors committed a common error by interpreting correlations involving difference scores without reference to the properties of the components of the difference. (SLD)

Available from: Ablex Publishing Corporation, 355 Chestnut Street, Norwood, New Jersey 07648. Two groups (high and low functioning) of educable mentally handicapped children consisting of 70 Ss' average age 127 months' were tested for strategies in their approach to memory and problem solving tasks and for their responsiveness to strategy…

Confirmatory factor analysis was used to test first- and second-order factor models on cognitive abilities and their invariance across samples of 234 male and 225 female secondary school students. Factor models suggest that males and females may use different problem-solving strategies for spatial analogies, matrices, and numerical problems. (SLD)

This study of individual differences in performance of a geometric analogies task included four-alternative test items and studied eye movements and confidence judgments as well as latency and error. Results were interpreted using two hypothesized performance strategies: constructive matching and response elimination. (Author/BW)

Retarded and nonretarded persons were compared on a task designed to preclude the use of cognitive strategies. Results suggest the possible importance of automatic processing deficiencies and invite a reconsideration of the idea that the relationship between intelligence and memory is due entirely to effortful processes. (LMO)

Relationships between brain-lesion location and behavior in 33 males and 31 females with unilateral lesions were studied. Statistical tests suggest that a single model can describe the relationships for females, but in males separate models of the relationships between lesion location, verbal intelligence quotient, and performance intelligence…
