Insights into the analysis of elaborative discourse activities and their impact on argumentative reasoning

辩证性话语对发展辩证性推理的关键作用似乎得到了充分的证明。然而，需要在内容层面上进行更彻底的分析，以确定具体的相互关联的交际行为，以培养辩论能力，并发展对特定主题的综合观点。但是，好的对话论证的指标到底是什么？通过这个拟议的项目，我的目标是通过哥伦比亚大学的研究奖学金，将库恩斯教授和我自己的专业知识结合在一起，从而回答这个研究问题。虽然库恩教授主要关注的是对辩论技巧发展的研究，但这个拟议的项目结合了她和我基于已收集的数据进行的研究：本项目将通过分析精心阐述的话语特征，如发展反驳论点，挑战他人的观点，或就它们对相互冲突的信息处理的影响提供解释，来扩大辩论的研究范围和建立论证的理论。为了实现该项目的目标，我计划重新分析库恩斯教授实验室收集的长期研究数据的子集。特别是，将对话语伙伴之间的相互作用进行调查。库恩教授和她的实验室擅长对过程进行编码，以找出之前的交流是如何影响进一步的交流行动的。在这种背景下，我可以在语篇数据的分析方面获得经验。结合库恩教授和她的实验室成员的能力和我自己在内容分析方面的知识，我将开发一种编码方案，捕捉议论文中各种交际动作。在此基础上，运用结构方程模型，将个体推理的质量和基于语篇的最终解决方案作为个体推理的依存度，来确定精致语篇活动与个体推理之间的相互关系。

The pivotal role of argumentative discourse for the development of argumentative reasoning seems well documented. However, a more thorough analysis on the content level is needed to identify specific interrelated communicative actions that foster the ability to argue and to develop an integrative perspective towards a given topic. But what exactly are indicators of good dialogic argumentation? With the proposed project I aim at answering this research question by bringing together Prof. Kuhns and my own expertise through a research fellowship at Columbia University. While Prof. Kuhn has primarily focused on the investigation of the development of argumentative skills, the proposed project combines her and my research based on data that have been collected already: The present project will broaden the scope of research and theorizing on argumentation by aiming at the analysis of elaborative discourse features, like developing counterarguments, challenging the others perspective or providing explanations with regard to their impact on the processing of conflicting information. To attain the goals of the project, I plan to re-analyze a subset of data from a long-term study that have been collected in Prof. Kuhns lab. In particular, the interplay between discourse-partners will be investigated. Prof. Kuhn and her lab are skilled in the coding of processes to find out how previous communication influences further communicational moves. In this context, I can gain experience in the analysis of discourse data. Combining the competence of Prof. Kuhn and her lab members with my own knowledge about content analysis I will develop a coding scheme capturing the variety of communicational moves in argumentative discourse. Then, the quality of individual reasoning and the final solution based on discourse are considered as dependent measures to determine the interrelations between elaborative discourse activities and individual reasoning by applying structural equation modeling.
