  1. 1. Preferential Processing: a factor with implications : Personality traits as explanatory factors

    Författare :Mats Najström; Lennart Högman; Anders Flykt; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Preferential preattentive processing; trait anxiety; emotional vulnerability; SCR; Psychology; Psykologi; psykologi; Psychology;

    Sammanfattning : Preferential processing favouring threatening information has received increased attention because cognitive formulations have placed increased emphasis on its role as a key cognitive factor underlying vulnerability to and maintenance of anxiety disorders. The present dissertation comprises four empirical studies within the area of preferential processing. LÄS MER

  3. 2. Does the way in which we perceive the world make us susceptible to anxiety?

    Författare :Billy Jansson; Lars-Göran Öst; Lars-Gunnar Lundh; Marcel Van den Hout; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Preattentive processing; selective attention; trait anxiety; defensiveness; emotional responses; emotional vulnerability; Psychology; Psykologi;

    Sammanfattning : One major focus of anxiety research in recent years has been the identification of cognitive factors that promote increased vulnerability to anxiety. Cognitive formulations propose that anxiety is characterised by an increased tendency to attend to negatively valenced emotional information, and that this bias may play a causal role in the development and maintenance of clinical anxiety.

  4. 3. Preattentive gaze control for robot vision

    Författare :Carl-Johan Westelius; Linköpings universitet; []
    Nyckelord :Robot vision; Resolution pyramids; Phase-based disparity estimation; Focus of attention; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : A framework for a hierarchical approach to gaze control of a robot vision system is presented, and a implementation on a simulated robot is described. The robot is equipped with a heterogeneous sampled imaging system, a fovea, resembling the varying resolution in a human retina. LÄS MER

  5. 4. Between Ourselves : Automatic mimicry reactions as related to empathic ability and patterns of attachment

    Författare :Marianne Sonnby-Borgström; Institutionen för psykologi; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; neurophysiology; neuropsychology; Neurology; emotion regulation; attachment pattern; empathy; EMG; Key words:Facial mimicry; emotional contagion; Differential and individual psychology; Neurologi; neuropsykologi; neurofysiologi; Differentiell och individuell psykologi;

    Sammanfattning : This thesis investigated emotional communication in experimentally created face-to-face interaction situations. The hypotheses were based on the conception of a process which leads to emotional empathy, assuming that automatic mimicking tendencies are involved in an automatic part of the process. LÄS MER

  7. 5. Focus of attention and gaze control for robot vision

    Författare :Carl-Johan Westelius; Hans Knutsson; Linköpings universitet; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : This thesis deals with focus of attention control in active vision systems. A framework for hierarchical gaze control in a robot vision system is presented, and an implementation for a simulated robot is described. LÄS MER
