中文摘要：

传统研究中,品牌承诺被认为是消费者抵御品牌负面信息的关键,高承诺消费者的品牌态度不易受到负面信息的影响。然而实验表明,这一过程会受到自我调节导向的调节：当消费者处于促进型调节导向的时候,低承诺消费者的品牌态度显著下降,而高承诺消费者的品牌态度不受影响;当消费者处于防御调节导向的时候,无论其品牌承诺高低,品牌态度均会受到负面信息的影响。这是因为处于防御调节导向的时候,高品牌承诺消费者的态度保护动机受到抑制,难以对品牌负面信息产生抵抗作用。研究还发现促进型调节导向的消费者较防御型调节导向的消费者更不容易受到品牌负面信息的影响。

In previous research, brand commitment is regarded as the key factor for consumers to resist negative publicity, scholars generally agree that consumers who have high brand commitment are less likely to change their brand attitudes when they are exposed to the brand＇s negative publicity. But this is not always the case, evidence shows that some of the high commitment consumers also lower their brand attitudes and even drop their purchasing behavior when facing the brand＇s negative publicity. Thus, It is reasonable to infer that the effect of brand commitment on consumers＇ responses to negative publicity could be dependent on certain conditions instead of linear. Based on the regulatory focus theory, this study examines whether regulatory focus can moderate the high commitment consumers＇ resistance to the negative publicity. Two studies were conducted to test the hypotheses that when consumers in prevention focus, no matter how high their brand commitment was, their brand attitudes would be lowered by the negative publicity; While when consumers in promotion focus, the low commitment consumers＇ attitudes would be lowered and the high commitment consumers＇ attitudes would remain the same. In study 1, a 2 （regulatory focus： prevention vs. promotion） × 2 （brand scandal： yes vs. no） between-subjects experiment was adopted. Firstly, Participants were required to see the target brand CANON＇s LOGO and introduction, reported their brand commitment and familiarity. Then, there regulatory focus were manipulated by using Lee, Keller and Sternthal （2010）＇s method; Thirdly, participants in the scandal group were exposed to Canon＇s negative publicity regarding its poor quality, and then reported their brand attitudes, involvements, etc, While participants in the control group reported their brand attitudes and involvements without being exposed to the negative publicity. Two-way ANOVA analysis on brand attitudes found a significant interaction between the brand commitment and regulatory foc
