n the context of single trial interactions can be generalized to iterated interactions.
For instance, Kelley and Thibaut (1978) have put forward that it is necessary to emphasize differences between single and repeated trial interactions "to counteract the unfortunate tendency for investigators to theoretically analyze a game in terms of ‘one-shot-play’ and then to be surprised when repeated play does not conform empirically to their analysis" (p. 163-64). Therefore, we decided to examine several of the hypotheses formulated by Insko et al. (1993) in their single trial communication study, but this time using iterated interactions. These hypotheses will be contrasted with predictions derived from goal-expectation theory (Pruitt 1983; Pruitt and Kimmel 1977).

Individual-Group Discontinuity

Schopler and Insko (1992) proposed two main hypotheses to account for the discontinuity effect2. According to the schema-based distrust-, or fear hypothesis, the effect is caused by the activation of an ‘ethnocentric outgroup schema’. They writ...
