Methods: Research emphasizes that language tests must be specific enough to capture subtle deficits in vocabulary and grammar learning at different developmental ages. The Diagnostic Receptive and Expressive Assessment of Mandarin (DREAM) was carefully designed to be a comprehensive standardized Mandarin assessment normed in China's Mainland. Results:This paper summarizes the evidence-based item design process and validity and reliability results of DREAM. A pilot study reported here shows that DREAM provided detailed information about hearing impaired children's language abilities and can be used to aid intervention planning to maximize progress. Conclusion: DREAM represents an example of translational science, transferring methods from empirical studies of language acquisition in research environments into applied domains such as assessment and intervention. Research on outcomes in China will advance significantly with the availability of evidence-based comprehensive language tests that measure a sufficient age range of skills, are normed on Mandarin speaking children in China's Mainland, and are designed to capture features central to Mandarin language acquisition.展开更多
目的获得噪声下声调识别测试（t o n e identification in noise test,TINT）材料的听力正常人识别成绩-强度（performance-intensity,PI）函数。方法利用已确立的TINT测试材料对16名年龄在21~28岁、以普通话作为日常交流语言的听力正...目的获得噪声下声调识别测试（t o n e identification in noise test,TINT）材料的听力正常人识别成绩-强度（performance-intensity,PI）函数。方法利用已确立的TINT测试材料对16名年龄在21~28岁、以普通话作为日常交流语言的听力正常人进行声调识别测试,使用SPSS17.0统计软件对结果进行分析。结果听力正常成人PI斜率分别为8.6%/d B（男声）、7.3%/d B（女声）（P=0.11）;听力正常成人PI函数信噪比50阈值分别为男声（-12.9±0.8）d B、女声（-13.6±1）d B（t=2.7,P=0.016）;声调类型和播音者性别对PI曲线阈值的影响即存在交互作用（F=11.7,P〈0.001）、亦存在独立作用（声调类型：F=83.7,P〈0.001;播音员性别：F=31.0,P〈0.05）,其中听力正常人一声和四声识别阈值明显低于二声和三声识别阈值。结论本研究初步建立基于TINT测试材料的听力正常人噪声下声调识别PI函数,以期为临床工作和科学研究提供一个可选择的测量工具。展开更多
