Abstract Interpersonal affection was a valuable topic and bring to increasingly researched in the past few years. This study discussed the influence of Differential Mode of Association(DMA) showed in interpersonal affection. Previous study used IAT(Implicit Association Test) to study the affection differences between the self and others by pairwise comparison, but this kind of research can not compared multiple kinds of objects at the same time. De Houwer developed the Extrinsic Affective Simon Task(EAST)as single task to remedy these defection. EAST can measured implicit attitude at different objects at the same time, based on the difference reaction time between incompatible discrimination and compatible discrimination as the indicator, EAST measured implicit attitude indirectly by measuring the automatic association between concept words and attributive words. With randomly sampled 36 undergraduate students as subjects, completed the EAST under four kinds of interpersonal relationships conditions, which were the self, the relatives, the acquaintances and the strangers to confirm if interpersonal relationships associating themselves with affection in a DMA pattern. Experiment processed as follows: the self nouns, the relatives nouns, the acquaintances nouns and the strangers nouns were presented on the colored trials, whereas five positive and five negative adjectives were presented on the white trials. The nouns were either presented in a green or blue color. All participants were instructed to classify these words by pressing the good key or bad key depending on the meaning or color of the presented word, they were told that, if the word was white, then the meaning of the word was important. All participants were instructed to pressing the good key for white word with a positive meaning and to pressing the bad key for white word with a negative meaning. If the word was colored, they were instructed to pressing the good or bad key on the basis of the color of the word. By analyzed the results of the test trials on which colored words were presented. The results indicated that: (1)people were prone to associating themselves, the relatives with positive affection and associating strangers with negative affection, but not significant bias affection in acquaintances . (2) Interpersonal affection showed a DMA pattern in connection strength. This study suggested that influenced by Chinese culture, Chinese people showed a interdependent relationalism in individuals cognitive schema, those people close to the self in psychological distance have more closely connect to the positive affection, and those away form the self in psychological distance have more closely connect to the negative affection. People in different interpersonal distances within the DMA affects the extent of organization and processing of relevant information, result in differences in interpersonal affection.
