This study explores Chinese implicit theories of personality-behavior association and the impact of these implicit theories on interpersonal interaction behaviors in a first encounter with new person. Yang's (1999) 10 Chinese personality perception dimensions (competent, impotent, industrious, lazy, extraverted, introverted, other-oriented, self-centered, agreeable, and disagreeable) were used to construct 10 interaction scenarios involving a person displaying a particular dimension. A conceptual analysis of the various kinds of behaviors associated with these 10 dimensions was also conducted. We tested the hypothesis that implicit theories associating personality dimensions and behaviors have an impact on interactions by decreasing or increasing interpersonal threat. When the implicit theory decreases the interpersonal threat, further interaction with the target is sought. In contrast, when the implicit theory worsens the interpersonal threat, interaction with the target is terminated. Analysis of the responses of 728 Taiwanese undergraduates on the 10 interaction scenarios indicated that all behaviors stemming from the implicit theories of other-orientedness and agreeableness decreased interpersonal threat and increased interaction with the target person. Behaviors associated with impotence, self-centeredness, disagreeableness, laziness, and introversion increased interpersonal threat and eliminated further interaction. Behaviors associated with competence, industriousness, and extroversion decreased some threats and increased others with the result that participants tended to show more complicated interaction with the target. Results are discussed in terms of interpersonal interaction in Chinese culture.
