Abstract The current study employed an audiovisual blended-emotion stimulus to explore whether particular aspects of working memory (WM) and trait emotional intelligence (TEI) are significant determinants of linguistic complexity, accuracy, and fluency in second language (L2) writing. Fifty-nine L2 learners of Spanish completed a visuospatial WM task, four executive functioning tasks assessing inhibition, shifting, and updating abilities, a self-reported measure of TEI, and a writing task based on an animated short film that required participants to describe the plot of the film and express how they felt about it. Classical and Bayesian statistical methods were used to analyse the data. Updating ability proved to be the best variable to predict both subordination density and linguistic accuracy in L2 writing. Individual differences in controlled search and retrieval processes seem to account for these results. On the other hand, TEI was not linked to any of the L2 writing performance measures but did correlate negatively with updating ability. Furthermore, a trade-off was observed between fluency and lexical complexity, suggesting that paying attention to lexical choices to convey (emotional) meaning might slow down production speed.

第二语言写作中的工作记忆、执行功能和情商

摘要 当前的研究采用视听混合情绪刺激来探索工作记忆 (WM) 和特质情绪智力 (TEI) 的特定方面是否是第二语言 (L2) 写作中语言复杂性、准确性和流畅性的重要决定因素。59 名西班牙语 L2 学习者完成了一项视觉空间 WM 任务、四项评估抑制、转移和更新能力的执行功能任务、一项自我报告的 TEI 测量以及一项基于动画短片的写作任务，该任务要求参与者描述电影情节并表达他们对它的感受。使用经典和贝叶斯统计方法来分析数据。更新能力被证明是预测二语写作中从属密度和语言准确性的最佳变量。受控搜索和检索过程中的个体差异似乎可以解释这些结果。另一方面，TEI 与任何 L2 写入性能指标都没有关联，但确实与更新能力呈负相关。此外，在流畅性和词汇复杂性之间观察到了一种权衡，这表明关注词汇选择来传达（情感）意义可能会减慢生产速度。
