Effect of temperature on Occupants' anger

This study applied the brainwaves and verbal vote to measure anger in each PMV condition, to examine the impact of indoor thermal environment on the people's negative emotions. An experimental approach in a climate chamber based on PMVs was adopted. Seven healthy male university students' electroencephalograms were measured in each condition. Their EEGs were measured in each condition for 65 minutes. Brain waves were measured on eight spots of the frontal lobe, the temporal lobe and the parietal lobe. After 65 minutes, occupants' anger was measured by paper test for 2 minutes. As a result of the subjects' verbal voting to examine their level of anger by PMV, the level was lowest at PMV 0 and highest at PMV +3. As a result of calculating the Asymmetry Index of the alpha waves to examine the brain's asymmetrical activity according to PMV, the value was greatest at PMV 0, followed by PMV +1, and lower at PMV-3 and PMV +3. This means that the activity of the right hemisphere increased from the neutral temperature to the lower temperature or higher temperature. As a result of discussing the two models (emotional valence and motivation direction) on the asymmetrical activity of the brain, the influence of indoor thermal environment on anger was valid when the emotional valence model was applied and different from the mechanism of anger from the social relationships.
