Recent studies suggest that working memory training may benefit older adults; however, findings regarding training and transfer effects are mixed. The current study aimed to investigate the effects of a process-based training intervention in a diverse sample of older adults and explored possible moderators of training and transfer effects. For…

Scores on Raven's Progressive Matrices correlated positively with electroencephalogram-recorded alpha rhythm frequency (AF) in 101 healthy male adults, as did one test of verbal ability and one of mental performance. However, AF did not show significant relationships with general intelligence or spatial and arithmetic abilities. (SLD)

THE THREE MAIN PURPOSES OF THIS RESEARCH IN PROBLEM-SOLVING WERE (1) TO EVALUATE GROUP PERFORMANCE VERSUS PERFORMANCE NORMS BASED ON THE PROPERTIES OF THE PROBLEM, (2) TO STUDY INDIVIDUAL PERFORMANCE, AND (3) TO INVESTIGATE THE EFFECT THAT A PARTICULAR EDUCATIONAL LEVEL HAS ON THE PERFORMANCE OF THESE PROBLEMS. THE SUBJECTS USED CONSISTED OF A…

Timed performance measures from a coincidence timing task taking about 10 minutes are shown to have significant correlations with psychometric general intelligence in a group of 56 children. The mean absolute error across three conditions correlated -.294 with Raven's Standard Progressive Matrices scores but was sex-biased, with girls being less…

The purpose of this study was to investigate the effectiveness of DISCOVER, a performance- based assessment in identifying gifted Lebanese students. The sample consisted of 248 students (121 boys, 127 girls) from Grades 3-5 at two private schools in Beirut, Lebanon. Students were administered DISCOVER and the Raven Standard Progressive Matrices…

Studies of human problem solving have traditionally used deterministic tasks that require the execution of a systematic series of steps to reach a rational and optimal solution. Most real-world problems, however, are characterized by uncertainty, the need to consider an enormous number of variables and possible courses of action at each stage in…

Evidence for suggested basic differences in the abstract reasoning capacity of Negro and Caucasian children includes consistent findings of significantly poorer performance by Negroes on Raven's Progressive Matrices (PM). This study investigated the PM performance of Negro children taught algebra via a discovery method of instruction. It was…
