    Sammanfattning : The present thesis explored the neurobiological basis of three aspects of defense behaviors in humans. Positron emission tomography methodology was used, and changes in regional cerebral blood flow (rCBF) were measured as an index of neural activity. LÄS MER

  3. 42. Binding Three Kinds of Vision

    Författare :Leo Poom; Myron Braunstein; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Psychology; Attribute-invariance; binding; contours; edge linking; gestalt-laws; illusory contour; lateral interactions; neuronal mechanisms; tilt effect; vision; Psykologi; Psychology; Psykologi; Psychology; psykologi;

    Sammanfattning : Pictorial cues, together with motion and stereoscopic depth fields, can be used for perception and constitute ‘three kinds’ of vision. Edges in images are important features and can be created in either of these attributes. LÄS MER

  4. 43. On the relationship between psychometric intelligence and decision making in dynamic systems

    Författare :Georgios Rigas; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Psychology; Advanced progressive matrices; complexity continuum; complex problem solving; decision-making; dynamic systems; intelligence; intransparency; microworlds; task novelty; Psykologi; Psychology; Psykologi; Psychology; psykologi;

    Sammanfattning : The relationship between psychometric intelligence and performance in dynamic decision making systems (microworlds) was investigated. A theoretical analysis of the mental processes that underlie performance in intelligence tests and microworlds suggested that at least some weak positive correlations should be expected. LÄS MER

  5. 44. Modelling self-reported aberrant driving behaviour

    Författare :Per-Arne Rimmö; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Psychology; Driving behaviour; Self-reports; Errors; Violations; Personality; Factor analysis; Psykologi; Psychology; Psykologi; Psychology; psykologi;

    Sammanfattning : The highly complex behaviour involved in driving a vehicle may be viewed as a form of action control in a potentially hazardous traffic system. Behavioural adaptation to the traffic system is imperfect, as is sometimes reflected in mishaps and road traffic accidents. LÄS MER

  7. 45. Aspects of Declarative Memory Functioning in Adulthood : Cross-Sectional and Longitudinal Studies

    Författare :Michael Rönnlund; Elizabeth Maylor; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Psychology; aging; episodic memory; sematic memory; encoding support; crosssectional; longitudinal; Psykologi; Psychology; Psykologi; Psychology; psykologi;

    Sammanfattning : The general objective of the thesis was to examine aspects of declarative memory functioning across the adult life span. The four papers were based on data collected as part of the Betula Prospective Cohort Study (Nilsson et al., 1997) and included largescale population-based samples of participants in the age range 35 to 90.
