2. 1. Human Rationality : Observing or Inferring Reality

   Author : Maria P. Henriksson; Mats Fredrikson; Henrik Olsson; Klaus Fiedler; Uppsala universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; supervised learning; unsupervised learning; adaptation; niche picking; prototypes; rules; exemplar memory.; Psychology; Psykologi;

   Abstract : This thesis investigates the boundary of human rationality and how psychological processes interact with underlying regularities in the environment and affect beliefs and achievement. Two common modes in everyday experiential learning, supervised and unsupervised learning were hypothesized to tap different ecological and epistemological approaches to human adaptation; the Brunswikian and the Gibsonian approach.

4. 2. A Division-of-Labor Hypothesis : Adaptations to Task Structure in Multiple-Cue Judgment

   Author : Linnea Karlsson; Peter Juslin; David Lagnado; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; multiple-cue judgment; exemplar models; cue abstraction; cue-combination rule; Cognitive science; Kognitionsvetenskap;

   Abstract : Judgments that demand consideration of pieces of information in the environment occur repeatedly throughout our lives. One professional example is that of a physician that considers multiple symptoms to make a judgment about a patient’s disease. READ MORE

5. 3. Similarity-based processes in human multiple-cue judgment : evidence from brain imaging and cognitive modelling

   Author : Sara Stillesjö; Linnea Karlsson Wirebring; Lars Nyberg; Håkan Nilsson; Alan Sanfey; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; multiple-cue judgment; similarity-based; rule-based; exemplar-based model; fMRI; cognitive modelling;

   Abstract : Background: We often make judgments that require the consideration of several sources of information. For example, a teacher that grades a student´s exam question often integrates multiple sources of information (cues: details provided in the answer) into a single criterion dimension (the grade).

6. 4. Process and representation in multiple-cue judgment

   Author : Anna-Carin Olsson; Peter Juslin; Umeå universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Psychology; Psykologi;

   Abstract : This thesis investigates the cognitive processes and representations underlying human judgment in a multiple-cue judgment task. Several recent models assume 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).

7. 5. Additive Integration of Information in Multiple-Cue Judgment

   Author : Linnea Karlsson; Peter Juslin; Tommy Gärling; Umeå universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Psychology; Psykologi; Psychology; psykologi;

   Abstract : This thesis investigates adaptive shifts between different cognitive processes in multiple-cue judgment tasks. At least two qualitatively and quantitatively different cognitive strategies can be identified: one process in which abstraction and integration of cue-criterion relations form the basis for the judgment (Einhorn, Kleinmutz & Kleinmutz, 1979) and one which is based onsimilarity comparisons between a probe and similar exemplars stored in memory (Medin & Schaffer, 1978; Nosofsky, 1984; Nosofsky & Johanssen, 2000).
