This study aimed to develop a dual-task Mandarin Reading Span Test (RST) to assess verbal working memory related to speech perception in noise.
The test material was developed taking into account psycholinguistic factors (i.e. sentence structure, number of syllables, word familiarity, and sentences plausibility), to achieve good test reliability and face validity. The relationship between the 28-sentence Mandarin RST and speech perception in noise was confirmed using three speech perception in noise measures containing varying levels of contextual and linguistic information.
The study comprised 42 young adults with normal hearing and 56 older adult who were hearing aid users with moderate to severe hearing loss.
In older hearing aid users, the 28-sentence RST showed significant correlation with speech reception thresholds as measured by three Mandarin sentence in noise tests ( or = -.681 to -.419) but not with the 2-digit sequence Digit-in-Noise Test.
The newly developed dual-task Mandarin RST, constructed with careful psycholinguistic consideration, demonstrates a significant relationship with sentence perception in noise. This suggests that the Mandarin RST could serve as a measure of verbal working memory.
本研究旨在开发一种双重任务普通话阅读广度测试（RST），以评估与噪声下言语感知相关的言语工作记忆。
考虑到心理语言学因素（即句子结构、音节数、单词熟悉度和句子合理性）来开发测试材料，以实现良好的测试可靠性和表面效度。使用包含不同程度语境和语言信息的三种噪声下言语感知测试，确认了 28 个句子的普通话 RST 与噪声下言语感知之间的关系。
本研究包括 42 名听力正常的年轻成年人和 56 名使用助听器的中老年听力损失患者。
在老年助听器使用者中，28 个句子的 RST 与三种普通话句子噪声测试（r=-.681 至-.419）中的言语接收阈值显著相关，但与 2 位数序列噪声测试（Digit-in-Noise Test）不相关。
新开发的双重任务普通话 RST，经过精心的心理语言学考虑构建，与噪声下的句子感知有显著关系。这表明普通话 RST 可以作为言语工作记忆的测量工具。
