Item Insight problem solving: An examination of the process and training of insight(1994) Bohannon, Nancy Kimberly; Brelsford, John W., Jr.In two studies, the process of insight as used in problem solving and the training of insight were examined. In Experiment 1, subjects either practiced solving insight problems or studied insight problems before attempting to solve an insight problem where they were able to ask limited questions of the experimenter. In Experiment 2, subjects were either trained on identifying common assumptions or given practice solving insight problems. Solution rates and verbal protocols for four test problems were collected. Neither study provided evidence of the re-organization of subjects' problem knowledge (as modeled by the Pathfinder algorithm) during problem solution. Though type of training did influence the rate and types of questions asked when solving the test problems, it did not facilitate the actual solution of those problems. The definition of insight was discussed as the identification of relevant and irrelevant problem features rather than as a change in problem representation.Item The effects of warning modality, warning formality, and product on safety behavior(1990) Donner, Kimberly Ann; Brelsford, John W., Jr.A warning compliance study, conducted on 170 university undergraduates, compared the rates of safety compliance with three forms of instruction and warning information (written, oral, and combination) and two forms of message formality (formal and informal). Under the guise of a cover story, subjects were presented with the material and told to read (or listen to) it before performing routine product tasks. Dependent measures were compliance with the warning and time spent with the material. Compliance with the warning information was significantly affected by product. Predictor information included gender, previous product use, and product hazard rating. Hazard rating of the product was reliably correlated with product and with safety compliance. Time spent with the instruction and warning information was reliably correlated with gender, but was not significantly correlated with safety compliance. The results are discussed with regard to the warning situation and in comparison to previous risk perception research.
