The tendency of customers' preference to their local brands over the foreign ones is known as consumer ethnocentrism, and it is an important issue in international marketing. This study aims at identifying the behavioral and neural correlates of Consumer Ethnocentrism in the field of brand preference, using event-related potential (ERP). We sampled subjects from two ethnic groups, a Chinese ethnic group and a sub-Saharan Black African group from Zhejiang University. The subjects faced two sequential stimuli, S1 followed by S2. S1 consisted of 40 pictures of 20 Chinese and 20 Black Africans people wearing traditional clothes, and S2 consisted of 40 fake brand-logos which were divided randomly into two groups of 20 each. The subjects were informed that the people in S1 purchased and recommended the products with the brand-logos presented in S2, and the subjects were asked to rate their preference degree toward these logos. The brand-logos were called the "in-group recommended logos" if the recommenders in S1 were the same race as the subjects, otherwise, the "out-group recommended logos." The results revealed that the race of the brand-logo recommender highly impacted the Chinese subjects' preference for the brand-logos. The N200 component elicited by the in-group recommended logos were significantly lower than those elicited by the out-group recommended logos. Additionally, there was evidence that being familiar with foreign cultures reduced consumer ethnocentrism. The African subjects were familiar with Chinese people and adopted a Chinese culture, as a result, they did not differ in showing preferences between the in-group and out-group recommended logos.
