  1. 1. Valence-Level Dependent Presentation-Order Effects in Preference Judgments

    Författare :Mats P. Englund; Åke Hellström; William M. Petrusic; Stockholms universitet; []

    Sammanfattning : Reversal of the stimulus-presentation order often affects the outcome in paired stimulus comparison. Psychophysicists have found that the size and direction of the order effects depend on the compared stimuli’s magnitudes, but this magnitude dependence does not seem to have been recognized previously in cognitive research on preference judgment.

  3. 2. Processing Asymmetries of Emotionally Valenced Stimuli

    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Psychology; recollective experience; remember-know; memory; encoding; processing asymmetries; emotional words; emotional faces; affective pictures; emotion; affective information; Psykologi;

    Sammanfattning : The central phenomenon investigated concerns the valence-based process asymmetry found in several earlier studies (e.g. Pratto & John, 1991; Taylor, 1991), where negative stimuli seem to initiate more thorough processing than positive stimuli. This finding was consistent in the three empirical studies forming this dissertation. LÄS MER

  4. 3. Emotional facial processing in younger and older adults

    Författare :Joakim Svärd; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : There is evidence that older adults have difficulty processing negative but not positive facial expressions. This positivity effect among older adults is expressed in attention to as well as in memory and recognition of emotional faces. In the present thesis, effects of stimulus properties (i.e. LÄS MER

  5. 4. Biases in Visual Selective Attention : Trait Anxious Individuals Avert Their Gaze From Unpleasant Stimuli

    Författare :Jean-Christophe Rohner; Institutionen för psykologi; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Psychology; eye-movements; attentional biases; Anxiety; attention; Psykologi;

    Sammanfattning : Cognitive models of anxiety postulate that anxious individuals are inclined to pay more attention to negative than to positive emotional visual stimuli. The main aim of the present dissertation was to test this prediction, employing a measure of the direction of gaze. LÄS MER

    Nyckelord :Faces; Facial expressions; Schematic faces; Threatening faces; Emotion; Semantic differential scales; Activity; Potency; Negative Evaluation; Attention; Visual search;

    Sammanfattning : We look at the things that matter to us. We may rest our eyes on things that attract us, stare at something horrifying, or glare at someone we dislike: things that affect us emotionally are also things that capture our visual attention. LÄS MER
