  2. 1. Factors Shaping Process and Representation in Multiple-Cue Judgment

    Author : Anna-Carin Olsson; Peter Juslin; Nigel Harvey; Umeå universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Psychology; Multiple-Cue Judgment; categorization; cognitive processes; knowl-edge representations; exemplar-based models; cue abstraction models; Psykologi; Psychology; Psykologi; Psychology; psykologi;

    Abstract : This thesis investigates the cognitive processes and representations underlying human judgment in a multiple-cue judgment task. Several recent models as-sume that people have several qualitatively distinct and competing levels of knowledge representations (Ashby, Alfonso-Reese, Turken, & Waldron, 1998; Erickson & Kruschke, 1998; Nosofsky, Palmeri, & McKinley, 1994; Sloman, 1996).

    Abstract : The inverse base-rate effect is the observation that on certain occasions people classify new objects as belonging to rare base-rate categories rather than common ones (e.g., D. L. READ MORE

  5. 3. Bounded Rationality and Exemplar Models

    Author : Magnus Persson; Peter Juslin; Nick Chater; Uppsala universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Psychology; PROBEX; Lazy Algorithm; Probabilistic Inference; Decision Making; Bounded Rationality; Ecological Rationality; Take The Best; exemplar models; correspondence; Psykologi; Psychology; Psykologi; Psychology; psykologi;

    Abstract : Bounded rationality is the study of how human cognition with limited capacity is adapted to handle the complex information structures in the environment. This thesis argues that in order to understand the bounded rationality of decision processes, it is necessary to develop decision theories that are computational process models based upon basic cognitive and perceptual mechanisms.
