CROSS LINGUISTIC STUDIES ON SPOKEN LANGUAGE PROCESSING

长期目标是理解口语 跨语言处理。这一目标对健康的影响 涉及言语知觉和语言功能研究的临床应用 听觉单词识别。跨语言研究界定了 理论和确定在人类语言中可操作的参数 正在处理。该计划的具体目的是进行以下方面的研究： 语音对言语知觉的影响，(2)词法对词的影响 再认和(3)词汇结构/语音特征对单词的影响 承认。四个关键实验解决了第一个目标。实验A1 用美式英语测试发音停止处的知觉突显 (AE)和日本听众。信号检测分析用于比较 组。实验A2是A1的复制，带有日本生产的刺激物 爱说话的人。实验A4-5在AE和印地语的比较中具有相同的设计 听众。有两个实验解决了第二个具体目标。实验B1测试 声发射听觉单词识别中词缀的分解。实验B2做的是 芬兰人也是如此。这些实验的比较将突出处理 基于两种语言非常不同的词法的差异。二 实验解决了第三个具体目标。这些是日语的复制品 两个重要的实验展示了词汇结构在 听觉单词识别。这些实验测试了 音节结构在听觉单词识别中的词汇密度效应。

The long-term objective is to understand spoken language processing cross-linguistically. The health implications of this objective relate to the clinical application of research on speech perception and auditory word recognition. Cross-linguistic studies delimit the range of theories and identify parameters that are operative in human language processing. The specific aims of the project are to conduct studies on (1) the impact of phonology on speech perception, (2) the impact of morphology on word recognition and (3) the impact of lexical structure/phonotactics on word recognition. Four key experiments address the first of these aims. Exp. A1 tests the perceptual salience of stop place of articulation by American English (AE) and Japanese listeners. Signal detection analysis is used to compare the groups. Exp. A2 is a replication of A1 with stimuli produced by Japanese talkers. Experiments A4-5 have the same design in a comparison of AE and Hindi listeners. Two experiments address the second specific aim. Exp. B1 tests for the decomposition of suffixes in AE auditory word recognition. Exp. B2 does the same for Finnish. Comparison of these experiments will highlight processing differences based on the very different morphologies of the two languages. Two experiments address the third specific aim. These are replications in Japanese of two important experiments demonstrating the role of lexical structure in auditory word recognition. These experiments test for mediating effects of syllable structure in the lexical density effect in auditory word recognition.
