■化妆品行为是一项重要的日常活动,尤其是对女性来说,因为它增加了视觉吸引力,自信,和积极的情绪。然而,在这一系列美容行为中,生理测量和主观体验之间是否存在关系是未知的。
■30名女性参与者的脑电图(EEG)和心电图(ECG),要求他们在使用护肤品后照镜子,以及基地,眼睛,脸颊,并记录唇妆。还考虑了化妆品产品的价格范围。皮肤表面的主观评价,情感,在化妆行为的每个步骤都照镜子后,同样测量自信。拟合线性混合模型以检查主观体验是否可以通过各种化妆品和/或生理反应来解释。
■使用因子分析将主观评价归纳为以下三个因素:自信,享乐主义感知,和负面情绪。每个theta波段(4-6Hz)功率,脑电图的α波段(8-13Hz)功率,和心率变异性测量分别进行主成分分析。线性混合模型表明,自信得分和负面情绪得分的变化只能通过整容行为的步骤来解释。也就是说,随着美容行为步骤的进行,自信心增加,而负面情绪减少。另一方面,享乐感得分是通过化妆品行为和价格的步骤的相互作用来解释的,这表明,当使用豪华化妆品时,积极的触觉和积极情绪比使用负担得起的产品时更高。此外,该模型表明,享乐感评分与枕骨部位的α带功率呈正相关,而交感神经系统活动与中央外侧部位的α带功率呈负相关.
■这些结果表明,积极的感知和情感体验与对体感信息的关注比对视觉信息和交感神经系统活动的关注更大。目前的结果还强调了使用生理测量作为化妆品行为的客观测量的可能性。
UNASSIGNED: Cosmetic behavior is an important daily activity, especially for women, because it increases visual attractiveness, self-confidence, and positive emotions. However, it is unknown whether a relationship exists between physiological measures and subjective experiences during the series of cosmetic behaviors.
UNASSIGNED: Electroencephalograms (EEG) and electrocardiograms (ECG) from thirty female participants who were asked to look in a mirror after applying skincare, as well as base, eye, cheek, and lip makeup were recorded. The price range of cosmetic products was also considered. Subjective evaluations of the skin surface, emotions, and self-confidence were equally measured after looking in the mirror at each step of the cosmetic behavior. Linear mixed models were fitted to examine whether the subjective experience could be explained by the variety of cosmetic products and/or physiological responses.
UNASSIGNED: The subjective evaluation was summarized into the following three factors using a factor analysis: self-confidence, hedonic perception, and negative emotion. Each theta-band (4-6 Hz) power, alpha-band (8-13 Hz) power of the EEG, and heart rate variability measures were subjected to a principal component analysis separately. The linear mixed models indicated that the variation in the self-confidence score and the negative emotion score was explained only by the steps of cosmetic behaviors, that is, self-confidence increased while negative emotions decreased as the steps of cosmetic behaviors proceeded. On the other hand, the hedonic perception score was explained by the interaction of the steps of cosmetic behaviors and price, indicating that positive tactile perception and positive emotion were higher when luxury cosmetic products were applied than when affordable products were applied. Furthermore, the model indicated that the hedonic perception score was positively associated with the alpha-band power over occipital sites whereas sympathetic nervous system activity was negatively associated with the alpha-band power over lateral central sites.
UNASSIGNED: These results suggest that positive perceptual and emotional experiences are associated with greater attention to somatosensory information than to visual information and sympathetic autonomic nervous system activities. The current results also emphasize the possibility of using physiological measurements as objective measures of cosmetic behavior.
