Event Abstract Back to Event Event-related potentials to aversive environmental sounds Kinga Gyimesi1, 2*, I Czigler1, T. J. Cox1 and J. Horváth1 1 Institute for Psychology of the Hungarian Academy of Sciences, Hungary 2 Budapest University of Technology and Economics, Hungary Emotionally negative (aversive) sounds and everyday sounds were presented as novel sounds in an auditory 3-stimulus paradigm. Both type of novel sounds elicited the orientation-related P3a component. In comparison to everyday sounds, the aversive sounds elicited a posterior negative component in the 154-250 ms range. The early negativity was followed by a frontal positive wave (372-456 ms). Compared to everyday sounds, the aversive sounds elicited larger late positive shift. The early negativity is considered as an initial effect in a broad neural network including limbic structures, while the late positivity is assumed to be related to the continued (deeper) processing of motivationally significant, memory-related processes.
