Psychophysiological Analysis of Sound Stimuli

Abstract

Electroencephalography signals (EEG) has captured the general interest of the scientific community; nowadays, the most part of the investigations of the topic are focused on the emotional psychophysiological effect that this kind of signals are able to show according different types of stimuli; therefore, this document shows the analysis of different sets of EEG signals, captured by NeuroSky headset, under the stimulation produced by emotional content sounds from the IADS (International Affective Digital Sounds); furthermore, some EEG signals from the "DREAMER" dataset were also analyzed. From this document was mainly concluded that there was a corresponsive result between subjective and objective data as valence and arousal values were corresponsive with EEG frequency bands; furthermore, for DREAMER set, electrodes of the right hemisphere were the ones with more energy.
