This manuscript investigates the role of argumentative competence in interpersonal dyadic exchanges. Specifically, this study examined the two sub-dimensions of competence, argumentative effectiveness and appropriateness, and their connections with argumentative traits, situational features, and argument satisfaction. In addition, self-perceived versus observed argumentative competence were compared. Participants in the study (N = 282, 141 dyads) completed measures before and after a face-to-face argumentative discussion with another person about one of two possible topics (student athlete pay and texting while driving). Results revealed that argumentation traits had little effect on argumentative competence, but competence was predicted by one’s knowledge about the topic. Argument satisfaction depended only on arguers’ own competence, not their partners’. Finally, a perceptual bias existed regarding argument effectiveness (but not appropriateness) in that participants rated themselves higher than did observers.

朋友和陌生人二元交流中的辩论能力

这份手稿调查了辩论能力在人际二元交流中的作用。具体而言，本研究考察了能力、论证有效性和适当性这两个子维度，以及它们与论证特征、情境特征和论证满意度的联系。此外，还比较了自我感知与观察到的辩论能力。该研究的参与者（N = 282，141 个二元组）在与另一个人就两个可能的主题之一（学生运动员支付和开车时发短信）进行面对面的辩论讨论之前和之后完成了测量。结果表明，辩论特质对辩论能力的影响很小，但能力是由一个人对主题的知识预测的。论证的满足只取决于论证者自身的能力，不是他们的合作伙伴。最后，在论证有效性（但不是适当性）方面存在感知偏见，因为参与者对自己的评价高于观察者。
