Evaluating Autonomic Parameters: The Role of ‎Sleep ‎Duration in Emotional Responses to Music

It has been recognized that sleep has an important effect on emotion processing. The aim ýof this study was to investigate the effect of previous night sleep duration on autonomic ýresponses to musical stimuli in different emotional contexts.ý
A frequency based measure of GSR, PR and ECG signals were examined in 35 healthy ýstudents in three groups of oversleeping, lack of sleep and normal sleep. ý
The results of this study revealed that regardless of the emotional context of the musical ýstimuli (happy, relax, fear, and sadness), there was an increase in the maximum power of ýGSR, ECG and PR during the music time compared to the rest time in all the three ýgroups. In addition, the higher value of these measures was achieved while the ýparticipants listened to relaxing music. Statistical analysis of the extracted features ýbetween each pair of emotional states revealed that the most significant differences ýwere attained for ECG signals. These differences were more obvious in the participants ýwith normal sleeping (p There was a strong relation between emotion and sleep duration, and this association can ýbe observed by means of the ECG signals.ý
