Preexposure To Visually Presented Forms And Nondifferential Reinforcement In Perceptual Learning

, : Preexposure To Visually Presented Forms And Nondifferential Reinforcement In Perceptual Learning. Journal of Experimental Psychology 69: 257-262

An experimental clarification of previous preexposure experiments which seemed to support the differentiation viewpoint of perceptual learning was undertaken. Seventy-nine albino rats were reared from birth in a visually sparse environment. Circles and triangles hung in the cages of the experimental Ss. Nondifferential food reinforcement of these cage stimuli was varied, and the resultant effect on subsequently learning to discriminate between them was examined. Discrimination performance of the main experimental groups confirmed the hypothesis that nondifferential reinforcement played a role in previous preexposure studies of perceptual learning, thus supporting the enrichment approach. Results for supplementary groups necessitated expansion of that approach to include possible reinforcing effects of novelty.

Phthalate exposure was reported to be associated with diabetes mellitus (DM) and cardiovascular disease (CVD). Yet, reported associations and the potential sex differences are inconsistent.

A growing body of evidence indicates that the powerful oxidant peroxynitrite (ONOO(-)) may function as an intracellular signal for production of proinflammatory cytokines, such as interleukin-8 (IL-8) in human leukocytes. In this study, we investi...
