摘要
为更客观地获取用户的产品意象数据,应用事件相关电位技术探讨了用户感知意象的思维表征。对154个国际知名品牌中的2 500款汽车造型进行筛选,得到经典车型720款。以16名大学生用户作为被试者,分别从中选择美观、中等和不美观图片各60幅,应用事件相关电位技术测试这些用户在欣赏各类图片时的脑电信号,并应用口语分析法获取其心理活动。结果显示,在第100 ms和第200 ms时,在大脑额叶Fz附近产生了脑电成分N1和P2;在第440 ms和第650~920 ms时,在大脑顶叶Cz,Cp1,Cp2和Pz位置产生了中期成分和晚成分。结果表明:漂亮、独特、协调、流畅、硬朗和简洁是大学生用户感知汽车造型的主要判断标准。在该感知过程中,用户在Cz,Cp1,Cp2及Pz位置的中期成分和晚成分可表征大脑思维,且两种成分的波幅可作为评价产品意象值的重要指标。该研究结果有助于提升产品意象获取手段的客观性,并有望应用于产品造型设计。
In order to obtain the user Product Image（PI）data more objectively,Event-Related Potentials（ERPs）technology was applied to analyze the user thinking representation.Among 154 world famous brands,720 classical cars were firstly chosen from 2 500 world famous ones.16 college users were chosen to list the beautiful,medium and not beautiful for 60 pieces in each classfication.Then ERPs technology was applied to test the subjects′ Electroencephalograms（EEG） when they appreciated these cars′ appearances.And Protocol Analysis Method（PAM）was used to aquire how the user made decision during the PIPP.The result showed that N1 and P2 appeared near Fz of Frontal Lobe in the 100^（th） ms and 200^（th） ms seperately.In addition,metaphase and late EEG components came into being near Cz,Cp1,Cp2 and Pz of Parietal Lobe in the 440^（th） ms and the 650^（th）~920^（th） ms accordingly.The results showed that the pretty,special,harmonious,fluent,hale and concise during the PIPP.During this process,the metaphase and late EEG componets near the Cz,Cp1,Cp2 and Pz could representthe brain thinking.The amplitude of both EEG components could be regarded as the important index in evaluating product image value.These results were useful to improve the objectivity of PI acquisition method,which was expected to be applied in the product modeling design.
