目前，热愉悦是根据心理和生理变量来衡量的。然而，在温度变化的瞬变环境中，很难将心理和生理措施联系起来，因为生理变化存在延迟。这项研究测试了一种使用脑电(EEG)将这两种测量相关联的方法，这种方法可以捕捉到快速响应的生理反馈。在本实验研究中，热愉悦是在温度阶跃变化的环境中产生的，这是一种非均匀的瞬变环境。实验期间进行脑电监测，通过问卷调查收集受试者对热感觉和热舒适的心理反应。共有50名20多岁的男性参加了一项气候室实验。一组25名男性被置于两种不同房间条件(32摄氏度，65%和25摄氏度，50%)之间的温度阶梯变化中，体验热快感。其余25名男性的对照组暴露在不变的条件下，体验接近热中性的热舒适。脑电频谱分析表明，与愉悦情绪相关的脑电频段(Theta)随着热快感的增加而增加，而与愉悦、满意或放松相关的频段(β)则随着热快感的增加而减少。
Thermal pleasure is currently measured along psychological and physiological variables. However, in transient environments where temperatures change, it is hard to correlate psychological and physiological measures, because there is a delay in physiological changes. This study tests a method for correlating both measures using electroencephalogram (EEG), which can capture physiological feedback with a rapid response rate. In this experimental study, thermal pleasure was induced in a temperature step-change environment, one of non-uniform and transient environments. During the experiment, EEG was monitored and psychological responses of thermal sensation and thermal comfort votes were collected via survey questionnaire. A total of 50 males in their twenties participated in a climate chamber experiment. An experimental group of 25 men were exposed to temperature step-change between two different room conditions (32 degrees C, 65% and 25 degrees C, 50%), experiencing thermal pleasure. The control group of the remaining 25 men were exposed to an unchanging condition, experiencing thermal comfort close to thermal neutrality. The EEG spectral analysis demonstrated that EEG frequency band associated with pleasant emotional (theta) increased while frequency band related to pleasantness, satisfaction or relaxation (beta) decreased with thermal pleasure.
