Sažetak
Emotional processing research encounters many debates and inconsistencies in results. There is an evidence for valence theory, but also for the right hemisphere theory. The goal of this research was to test hemispheric asymmetry related to emotional processing. To test those theories, two experiments with IAPS pictures were conducted. Valence of the pictures was manipulated (pleasant, unpleasant, neutral) as well as the side of the screen where the picture was presented (left/right), while intensity and dominance of presented pictures were controlled. Pictures were presented in pairs (neutral/pleasant and neutral/unpleasant) where participants evaluated which picture is pleasant/unpleasant by pressing the key on the left/right side (left/right hand) on the keyboard depending on which side of the screen the emotional picture was presented. Faster response is expected for unpleasant pictures presented on the left side (answer with the left hand) of the screen, and for pleasant pictures when are presented on the right side of the screen (answer with the right hand). Those results would confirm valence theory (left hemisphere is more active during processing pleasant emotions), which would be shown by faster reaction time in that condition when picture is presented in contralateral visual field and answered with contralateral hand.
