Effect of Emotions on Visual Evoked Potentials

The effects of anxiety and anger on the visual evoked potentials generated by exposure to visual stimuli (circle or square as compared to blank card) did not for 80 human Ss modify the latencies or the amplitude of P1, P2, N1 and N2 peaks. Anxiety and anger modified, however, in a statistically significant manner P3 and the following waves. The P3 – N4 wave complex seemed to relate to cognitive processes. The results suggest that the effects of cognitive processes related to anxiety and rage differ, at least in part.
