Two studies examined the communication of friendship interest within versus across group boundaries in relatively intimate exchanges. The main hypothesis was that so long as reasonable levels of friendship interest were in place, individuals would be more apt to exaggerate the clarity of their overtures (i.e., to exhibit a signal amplification bias) in intergroup as compared to within-group interaction. In line with predictions, this pattern was evident for lower-prejudice individuals, who were equally interested in ingroup and outgroup members as potential friends, but not for higher-prejudice individuals, who were relatively disinterested in cross-group friendship and instead tended to underestimate the friendship interest they conveyed to outgroup members. In contrast with the implications of past research centering on trait impressions and impersonal exchanges, both of these effects appeared to be driven by heightened feelings of transparency in intergroup as compared to within-group interaction.
两项研究考察了在相对亲密的交流中，群体内部与群体之间友谊兴趣的表达。主要假设是，只要友谊兴趣处于合理水平，与群体内部互动相比，个体在群体间互动中更倾向于夸大其主动表示的清晰度（即表现出信号放大偏差）。与预测一致，这种模式在低偏见个体中很明显，他们对内群体和外群体成员作为潜在朋友同样感兴趣，但在高偏见个体中则不然，他们对跨群体友谊相对不感兴趣，反而倾向于低估他们向外群体成员表达的友谊兴趣。与以往以特质印象和非个人交流为中心的研究结果相反，与群体内部互动相比，这两种效应似乎都是由群体间更高的透明度感受所驱动的。
