| Abstract |
This study investigates the electroencephalogram(EEG) associated with thermal displeasure with a sudden temperature increase. 18 males and 17 females participated in chamber experiment. They stayed in comfortable environment for 30 minutes and moved to uncomfortable environment then stayed for 20 minutes. They answered thermal sensation vote and thermal comfort vote during experiments. Their brainwave were measured for 50 minutes.
As results of the experiment, the relative theta power was decreased at the frontal lobe when people felt thermal displeasure. The relative beta power was increased at the parietal lobe and the relative gamma power was increased at the frontal lobe. This study indicates that the brainwave can measure thermal pleasure and displeasure with a sudden temperature increase. |
