بررسی پردازش عاطفی از ویژوال محرک از طریق پتانسیل وابسته به رخداد

The effect of emotional charge of visual stimuli on cerebral activity was investigated through ERPs. This emotional charge is explained through two dimensions: arousal (relaxing-activating) and valence (attractive-repulsive). Stimuli were 12 paintings selected through questionnaires: three activating-attractive pictures (A+ group), three activating-repulsive (A−), three relaxing (R), and three neutral (N). The ERPs were recorded from the 31 subjects at F3, Fz, F4, C3, Cz, C4, P3, Pz and P4. N200 and PFull-size image (<1 K)did not show significant reactions to the emotional charge of the stimuli. N300 showed greater amplitudes in response to activating stimuli: at frontal sites for A+ and at parietal sites for A−.
