摘要:
依托认知心理学领域中事件相关电位(ERP)研究手段,挖掘用户观察不同偏好家具产品时的典型脑认知成分特征,并结合经典视觉诱发情绪ERP研究成果,获取不同偏好程度的产品图片诱发用户脑电成分特征与情绪诱发脑电成分的关系。本研究以3种不同偏好度(高、一般、低)的办公椅图片为刺激素材,对其诱发的用户脑认知P3成分进行测量。基于20名被试的脑电数据,以峰值为因变量,用多因素方差分析对不同偏好度、被试性别及其交互作用对峰值产生的影响进行分析。结果表明:不同偏好程度因素主效应对脑认知P3成分的峰值强度影响显著,“低”偏好度图片组诱发的P3峰值显著高于“一般”与“高”偏好度的座椅图片组诱发的P3峰值,且顶区是诱发P3成分的主要脑区; 女性用户在脑认知过程中产生的P3成分峰值比男性更高,即女性受产品偏好程度影响波动较大; P3成分峰值不受偏好度、性别及脑区三因素交互作用的影响。相关研究结果与经典视觉诱发P3成分特征一致,因此用户对产品的偏好度(高、一般、低)与情绪(积极、中性、消极)存在关联性,ERP数据可作为产品诱发用户感性情绪认知的甄别指标。该研究过程与结果可为其他产品图片诱发用户脑认知研究提供参照。
Abstract:
The relationship between electroencephalogram(EEG)components and emotional-evoked EEG components in product pictures with different preferences was obtained by mining the characteristics of typical brain cognitive components when users observed products with different preferences.In this study, three different preference levels(high, middle and low)of office chair pictures were used as stimulus materials.Event-related potential(ERPs)technique was used to measure the evoked P3 components of brain cognition at physiological arousal level.Based on the EEG data of 20 subjects, the effects of different preferences, gender and their interaction on the peak value were analyzed by the two-way ANOVA with peak value as a dependent variable.The results showed that the main effect of different preference factors on the peak intensity of P3 components was significant.The peak intensity of P3 induced by low preference group was significantly higher than that induced by moderate and high preference group, and the top area was the main brain area inducing P3 components.The peak value of P3 component produced by female users in the cognitive process was higher than that of male users, which was to say, female users fluctuated greatly under the influence of product preference.The peak value of P3 component was not affected by the interaction of preference, gender and brain area.In a word, there were significant differences in user's brain perception of office chair products with different preferences, which verified the validity of the previous sample grouping results.The corresponding sample data can provide a reference for the later Kansei design of office chair products.In addition, relevant research results were consistent with the characteristics of classical visual evoked P3 components, so there was a correlation between user preference(high, general, low)and emotion(positive, neutral, negative).The research process and results can provide a theoretical reference for other products to induce brain cognition research.
