研究基于复杂动态系统理论，采用移动极值图、关键时间点及会话分析方法，从话轮长度和异议表达具体方法两方面分析三组会话者 13 周英语异议表达互动资源集的发展情况。结果表明，两个维度都随时间发生了非线性变化：话轮长度发展因人而异，个别学习者的话轮长度发生了有意义的突变；异议表达具体方法呈现出多元化发展趋势，其中“直接反驳”和“先肯定／重复后反驳”的发展优先于“非典型间接异议”。

Grounded in complex dynamic systems theory (CDST),this study tracked the development of six English learners’ interactional repertoire in disagreements over thirteen weeks by analyzing two dimensions:turn lengths and disagreement techniques. Dynamic Systems Theory methods including moving min-max graphs and the critical moment method were employed, along with qualitative methods such as conversational analysis. Results show that the two dimensions both experienced non-linear development during the observation period. Firstly, the development of turn lengths varied from person to person and some meaningful variability was found. Secondly, disagreement techniques were diversified, and the development of “direct disagreement”and “agreement / retelling +disagreement”was prior to that of “atypical indirect disagreement”.
