In the United States, many of the laws governing environmental conservation and management stipulate that the best available science be used as the basis for policy and decision making. The Endangered Species Act, for example, requires that decisions on listing a species as threatened or endangered be made on the basis of the "best scientific and commercial data available." Similarly, National Standard 2 of the Magnuson-Stevens Fishery Conservation and Management Act states that conservation and management measures shall be based on "the best scientific information available." Further, the U.S. Environmental Protection Agency has emphasized the role of best available science …
The Effects Of Category Overlap On Information-Integration And Rule-Based Category Learning, Shawn W. Ell, Gregory F. Ashby
The Effects Of Category Overlap On Information-Integration And Rule-Based Category Learning, Shawn W. Ell, Gregory F. Ashby
Psychology Faculty Scholarship
Three experiments investigate whether the amount of category overlap constrains the decision strategies used in category learning, and whether such constraints depend on the type of category structures used. Experiments 1 and 2 used a category learning task requiring perceptual integration of information from multiple dimensions (information-integration task) and Experiment 3 used a task requiring the application of an explicit strategy (rule-based task). In the information-integration task, participants used perceptual-integration strategies at moderate levels of category overlap, but explicit strategies at extreme levels of overlap – even when such strategies were sub-optimal. In contrast, in the rule-based task, participants used …
Focal Putamen Lesions Impair Learning In Rule-Based, But Not Information-Integration Categorization Tasks, Shawn W. Ell, Natalie L. Marchant, Richard B. Ivry

Previous research on the role of the basal ganglia in category learning has focused on patients with Parkinson’s and Huntington’s Disease, neurodegenerative diseases frequently accompanied by additional cortical pathology. The goal of the present study was to extend this work to patients with basal ganglia lesions due to stroke, asking if similar changes in performance would be observed in patients with more focal pathology. Patients with basal ganglia lesions centered in the putamen (6 left side, 1 right side) were tested on rule-based and information-integration visual categorization tasks. In rule-based tasks, it is assumed that participants can learn the category …
