{"pk":25997,"title":"Individual Differences in Base-rate Neglect: A Computational Dual Process Model","subtitle":null,"abstract":"Dual-process theories (DPT) of cognition posit that performance differences in reasoning stem from an interplay\nbetween heuristics-based processing (i.e., System 1) and more controlled, rule-based processing (System 2). Emerging evidence\nsuggests that solving classic base-rate problems via Bayesian inference depends on adequately inhibiting the prepotent\nrepresentations elicited by System 1 (De Neys, 2014). We propose that DPTs may benefit probabilistic models of reasoning by\nproviding a framework on which to map individual difference predictions (e.g., how inhibitory capacity, prior knowledge, and\nmotivation influence adherence to probabilistic rules). We present a dual-process computational model that implements various\nnormative (i.e., Bayesian) and non-normative rules, which in turn are probabilistically fired based on a functional relationship\nbetween relative (de)activations of each system and variability in agents’ inhibitory capacity and motivation. Simulation results\nmap onto behavioral data and replicate a variety of base-rate performance patterns, including base-rate neglect","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[],"section":"Member Abstracts","is_remote":true,"remote_url":"https://escholarship.org/uc/item/9065h072","frozenauthors":[{"first_name":"Carlos","middle_name":"","last_name":"Salas","name_suffix":"","institution":"University of Ilinois at Chicago","department":""},{"first_name":"Tim","middle_name":"","last_name":"Sparer","name_suffix":"","institution":"University of Ilinois at Chicago","department":""},{"first_name":"Sabrina","middle_name":"","last_name":"Velez","name_suffix":"","institution":"University of Ilinois at Chicago","department":""},{"first_name":"Thomas","middle_name":"","last_name":"Griffin","name_suffix":"","institution":"University of Ilinois at Chicago","department":""}],"date_submitted":null,"date_accepted":null,"date_published":"2015-01-01T18:00:00Z","render_galley":null,"galleys":[{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/25997/galley/15621/download/"}]}
