More Book Details

Description of the Book:

Results are reported for a study comparing the pattern of convergent and discriminant validity in relating information processing variables which represent basic numerical operations, an index of the facility of performing these operations within working memory, and ability measures defining Numerical Facility, Perceptual Speed, General Reasoning, and Memory Span. Analyses supported theoretically expected patterns of convergent and discriminant validity in relating process variables to individual-differences measures. The data also indicated that the relationship between distinct ability factors was due to common underlying operations. Different sets of ability factors, however, were found to correlate for different reasons, and not because of a pervasive general ability spanning all cognitive domains. Finally, implications for the nature of individual differences in human abilities were discussed. Keywords: Individual differences; Information processing; Intelligence
