Brain processing of affective picture stimuli: Modulations of the Late Positive Potential for semantic categories of pictures
Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
Affective brain processing of emotional pictures varies in regards to emotional dimensions of valence and arousal, but little research has studied effects of semantic content. To study the effects of semantic picture content on the late positive potential, event-related potentials were recorded from forty participants while they viewed 375 standard emotional pictures that were grouped into categories of semantic content. Results showed that semantic content had a significant effect on the amplitude of the late positive potential even after controlling for valence and arousal. However, a significant effect from any specific category could not be isolated. These findings suggest that semantic picture content is an important variable to consider in studies investigating the late positive potential in affective picture brain processing.
