Group and individually administered measure of intelligence were related to laboratory based measures of human information processing on a group of college freshmen. Among other results, high IQ was related to right hemisphere efficiency in processing non-linguistic stimuli. (Author/JKS)

The general ability factor (G), as enunciated by Charles Spearman in the model of cognitive functioning, has been the foundation of psychometric theory and test making practices for 80 years. Through these decades, some psychologists disagreed with this theory, especially Godfrey Thompson and E. L. Thorndike. Nevertheless, various aptitude tests…

In two six-month longitudinal studies of intellectually advanced preschool children, letter naming time and background digit span were moderately good predictors of concurrent reading achievement, while no other standard cognitive indices, including mental age, were associated with reading achievement. Both memory span and retrieval were related…

This study investigated the relationship between measures of speed of cognitive information processing and intelligence test scores. Cognitive processing measures were significantly related to IQ scores. Reaction time tests measure cognitive operations basic to intelligence, and individual differences in intelligence are partly due to variability…

During the last two decades of work in predicting and explaining school achievement, much research has emphasized the identification and measurement of student cognitive and affective processes which predict and also promise to help explain and facilitate school achievement. This review focuses on modifiable cognitive and affective processes, as…

This study was designed to examine the effects of auditory memory, visual memory, and vocabulary knowledge on intramodal and intermodal delayed matching-to-sample tasks. A secondary objective was to assess the value of task performance and trait measures in predicting reading achievement. A total of 52 first graders were randomly selected as…

The WPPSI was used in a Manhattan, N.Y., public school because administrators, teachers, and parents had asked for help in understanding children who had difficulty in learning to read well, despite special efforts to help them. A preventive intervention program was begun based on a clinical study of every first grader. Forty children were…
