Analysis of Reward Functions in Learning: Unconscious Information Processing: Noncognitive Determinants of Response Strength
Abstract
Our overall objective was to investigate the role of non-cognitive determinants of response strength. The more specific objective was to determine whether rewarded responses are differentially processed, as revealed by analysis of their subliminal processing. The major focus of the research was to ascertain the reality of claims. For example, that graphemic and semantic processing persists in spite of the subjects' inability to identify pattern-masked visual cues. In spite of timing limitations associated with the 60 Hz refreshing of our CRT display, we found consistent suprachance selection of test alternatives that were graphemic, phonemic, and semantic associates of the target words, in the absence of any ability to identify the target words themselves. Control stimulations (blanks) produced chance performance. It was concluded that these results (1) offer support for the reality of subliminal or unconscious information processing, (2) indicate the feasibility of subliminal testing of the hypothesized differential processing of rewarded responses, and (3) suggest the potential utility of adapting subliminal stimulation techniques as training procedures designed to enhance perceptual skills under severely degraded stimulus conditions, such as the detection of hidden targets in military operations.
