Abstract Details

1991, Doctor of Philosophy, Case Western Reserve University, Psychology.
The purpose of the current research was to systematically investigate the relationship between levels of perceptual structure and individual differences in cognitive ability. Two computerized studies were conducted. The first study tested the importance of changing dimensional relationships among novel perceptual stimuli (interstimulus structure) in the prediction of individual differences. The second study further defined two specific parameters of interstimulus structure: amount and form, and tested the relationship among parameters of interstimulus structure, individual stimulus complexity (intrastimulus structure), and individual differences in cognitive ability. The first study was conducted at Lackland Air Force Base with 220 Air Force recruits. The second study was conducted at Cleveland State University with 100 college undergraduates. Results from the first study indicated that changing dimensional structure between stimuli was an important factor in the prediction of individual differences in intelligence. Study 2 replicated and expanded results from Study 1. Parameters of interstimulus form and amount were identified as independent predictors of individual differences in mental ability in Study 2. Interstimulus form was the m ost highly related to individual differences in general cognitive ability. Mediating effects were identified for stimulus complexity and the order in which problems were presented. Basic cognitive processes of discrimination and learning predicted portions of the variance attributed to interstimulus amount and form, respectively. Interstimulus structure was an important predictor of individual differences in cognitive ability after effects of basic cognitive processes were partialed out. In sum, changing dimensional relationships between stimuli were important predictors of individual differences in general cognitive ability. Royer's (1978) structural model of individual differences was supported. Results were consistent with interpretations of Spearman's (1923) qualitative model of mental ability as a model of perceptual processing.
