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

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

    Sammanfattning : 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. LÄS MER

  3. 2. 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).

  4. 3. Knowledge Representation, Heuristics, and Awareness in Artificial Grammar Learning

    Författare :Tobias Johansson; Institutionen för psykologi; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; abstraction; awareness.; non-analytic processing; Artificial grammar learning; fluency; implicit learning;

    Sammanfattning : People can become sensitive to the general structure of different parts of the environment, often without studying that general structure directly, but through being incidentally exposed to instances that conform to the structure. When such learning proceeds unintentionally and gives rise to knowledge that is difficult to verbalize it is often referred to as implicit learning. LÄS MER

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

    Sammanfattning : 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).
