对“群体极化现象”的经典解释强调人际过程，如信息影响和社会比较（Myers & Lamm，1976）。基于早期的研究，我们假设，在小组讨论中观察到的极化至少有一部分可能是由于重复的态度表达。两项研究支持了这一假设。在研究1中，我们操纵了每个小组成员谈论一个问题的频率，以及他或她听到其他小组成员谈论这个问题的频率。我们发现，重复表达产生了可靠的转变，在极端。对小组讨论的详细编码表明，在小组成员重复彼此的论点并将其用于自己的推理路线的小组中，重复表达对态度极化的影响得到了加强。研究2通过实验测试了这种效果。结果表明，重复表达的效果在被指示使用对方论点的小组中得到了增强，而在被指示避免这种重复的小组中得到了增强。两者合计，这些研究表明，重复的表达占至少一部分的态度极化观察到的典型研究群体极化，这种效果是由社会互动增强，即，它发生在一个环境中，特别是在群体成员重复和验证对方的想法。
Classic explanations of the “group polarization phenomenon” emphasize interpersonal processes such as informational influence and social comparison (Myers & Lamm, 1976). Based on earlier research, we hypothesized that at least part of the polarization observed during group discussion might be due to repeated attitude expression. Two studies provide support for this hypothesis. In Study 1, we manipulated how often each group member talked about an issue and how often he or she heard other group members talk about the issue. We found that repeated expression produced a reliable shift in extremity. A detailed coding of the groups' discussions showed that the effect of repeated expression on attitude polarization was enhanced in groups where the group members repeated each other's arguments and used them in their own line of reasoning. Study 2 tested for this effect experimentally. The results showed that the effect of repeated expression was augmented in groups where subjects were instructed to use each others' arguments compared to groups where instructions were given to avoid such repetitions. Taken together, these studies show that repeated expression accounts for at least part of the attitude polarization observed in the typical studies on group polarization and that this effect is augmented by social interaction, ie, it occurs particularly in an environment where group members repeat and validate each other's ideas.
