二语口语广度测试及其对口语流利度的预测能力

L2 Speaking Span Test and Its Predictive Power of L2 Oral Fluency

口语广度测试是测量工作记忆容量的常用范式之一,但是该测试并不能全面准确地反映工作记忆同时加工和储存信息的能力。本文认为同时考虑加工准确度、加工效率和储存能力的综合口语广度更能准确地测量工作记忆容量,特别是二语学习者的工作记忆容量。实证数据还表明综合口语广度能够更好地预测二语口语流利度。

Speaking Span Test is one of the paradigms widely employed to measure working memory capacity,but it fails to tax the simultaneous information-processing and information-maintaining capacity of working memory as it claims. This paper argues that a Composite Speaking Span,which takes processing accuracy,processing efficiency and saving capacity into account,can better measure working memory capacity,especially that of L2 learners,and provides empirical evidence to show that the Composite Speaking Span is a better predictor of L2 oral fluency.
