2. 1. 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.

4. 2. 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).

5. 3. Desirable Victims: Systems of Refugee Selection in Swedish and Canadian Migration Governing

   Abstract : This thesis explores how states try to govern refugee migration by classifying and ordering its subjects. It argues that a unifying construct of state migration control is selection: to maintain a system that offers protection to wanted people and keeps out unwanted people. READ MORE

6. 4. Statistical analysis of gene expression data

   Author : Erik Kristiansson; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; gene expression; DNA microarrays; linear models; empirical Bayes; quality control; gene regulation; categorical data analysis; logistic regression; heavy metal stress; ecotoxicology; gene expression;

   Abstract : Microarray technology has become one of the most important tools for genome-wide mRNA measurements. The technique has been successfully applied to many areas in modern biology including cancer research, identification of drug targets, and categorization of genes involved in the cell cycle.

7. 5. The Role of High-Level Reasoning and Rule-Based Representations in the Inverse Base-Rate Effect

   Author : Pia Wennerholm; Koen Lamberts; Uppsala universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Psychology; inverse base-rate effect; rationality; human knowledge representations; exemplar-based models of categorization; eliminative inference; inference rules; rapid attention shifts; associations; Psykologi; Psychology; Psykologi; Psychology; psykologi;

   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
