INDIVIDUAL-DIFFERENCES AND INTERRELATIONSHIPS AMONG A SELECT SET OF COGNITIVE SKILLS

Individual differences and interrelationships in performance on 3 short term memory processing and visual processing tasks were investigated. Parameters of models of these tasks were correlated. High correlations (.97 and .83) were obtained for some intertask parameters, indicating that elemental component processes for different tasks can be identified that are similar or highly related. Psychometric measures (SATM Scholastic Aptitude Test for Math and SATV Scholastic Aptitude Test for Verbal Ability) were also correlated with the information processing model parameters. High multiple correlations of SATV and SATM were obtained using model parameters as predictors, when the data were analyzed separately for female and male [human] subjects. Sex differences in the interrelationships of the cognitive processes under investigation were possible.
