  1. 1. Visual Perception of the Facial Width-to-Height Ratio : Possible Influences of Angry Facial Expressions as Revealed by Event-Related Brain Potentials

    University essay from Högskolan i Skövde/Institutionen för biovetenskap

    Author : Madeleine Jones; [2019]
    Keywords : Facial Width-to-Height Ratio; Late Positive Potential; Facial Processing; Anger; Cognitive Neuroscience;

    Abstract : The facial width-to-height ratio (fWHR) is a measure of the cheekbone width divided by the height of the face from the upper lip to the brows. The metric is hypothesised to have evolved as an intra-sexual competition mechanism in males, where large fWHRs are thought to signal both threat and aggression. READ MORE

  2. 2. Facial age and anger expression : An event-related brain potential study

    University essay from Högskolan i Skövde/Institutionen för biovetenskap

    Author : Akwaththage Udayangani; [2019]
    Keywords : Late Positive Potential; Facial Age; Anger; Perception;

    Abstract : The perception of human faces is affected by different facial features. For example, older faces are processed differently to younger ones and faces expressing diverse emotions are also processed differently. READ MORE

  3. 3. Threatening Measures, at Face Value : Electrophysiology Indicating Confounds of the Facial Width-to-Height Ratio

    University essay from Högskolan i Skövde/Institutionen för biovetenskap

    Author : Carl Lindersson; [2019]
    Keywords : threat perception; evolutionary cues; fWHR; LPP; overgeneralisation hypothesis;

    Abstract : Previous studies support that the relative width of the upper face (facial width-to-height ratio; fWHR) has evolved to signal threat, but these studies rely greatly on subjective facial ratings and measurements prone to confounds. The present study objectively quantifies threat perception to the magnitude of the observers’ electrophysiological reaction, specifically the event-related potential (ERP) called the late positive potential (LPP), and investigate if brow height and jaw width could have confounded previous fWHR studies.

  4. 4. Thinking things over : The electrophysiology and temporal dynamics of self- and situation-focused reappraisal

    University essay from Högskolan i Skövde/Institutionen för biovetenskap

    Author : Emilia Svennersjö; [2018]
    Keywords : Cognitive reappraisal; emotion regulation; late-positive potential; temporal distancing; social distancing; situation-focused reappraisal;

    Abstract : Cognitive reappraisal is an emotion regulation strategy that has been shown effective in down-regulating negative emotions in both psychological and electrophysiological measures. Although there are many studies on cognitive reappraisal, only recently have there been studies differentiating between various ways of employing the strategy. READ MORE

  5. 5. Temporal Dynamics of Emotion Regulation Strategies: An ERP Study

    University essay from Högskolan i Skövde/Institutionen för biovetenskap

    Author : Omorinsola Olowe; [2018]
    Keywords : LPP; Emotion Regulation ER ; Reappraisal; Distraction; Angry face;

    Abstract : Distraction and cognitive reappraisal are two widely used types of emotional regulation strategies that are thought to be reliable when down-regulating our emotions to negative or unpleasant stimuli. Gross‘s process model of emotion generation (Gross, 1998) holds that they differ in the time they intervene in the emotiongenerative process and also how they impact emotional responses when they are used to regulate negative emotions.
