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

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

    Sammanfattning : 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).

  3. 2. Bounded Rationality and Exemplar Models

    Författare :Magnus Persson; Peter Juslin; Nick Chater; Uppsala universitet; []
    Nyckelord :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;

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

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

    Sammanfattning : 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).

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

    Författare :Pia Wennerholm; Koen Lamberts; Uppsala universitet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER
