RECOGNITION OF SPOKEN WORDS

听觉词汇再认理论假设心理活动的多个阶段 描述语音到单词的转换的表示法； 最后一个阶段是词汇，它的操作和功能在各个方面都有所不同 理论。拟议的研究审查了三个问题，涉及 词汇在单词识别中的作用，测试预测 在每个问题上划分的理论类别：(1)是否 词汇知识被用来促进言语感知；(2) 口语单词的一部分首先与其表征相联系 在词典中；(3)选择词条的过程 这与语音信号最匹配。 实验操作的设计是为了揭示 词典。刺激将由单词和句子组成，并且 单词的声学、语音和语义特征将是 多种多样。多个实验任务，如音素监测， 音素识别和跨模式启动将被用来探测 在识别系统中的不同阶段进行处理，并提供 在将要研究的问题上汇聚证据。专业化 计算机硬件、软件和音频设备将控制刺激 建设、展示和数据收集。调查结果应该是 有助于理解词汇在单词中的作用 承认。

Theories of auditory word recognition posit multiple stages of mental representation to describe the transformation of speech into words; the final stage is the lexicon, whose operation and functions differ across theories. The proposed research examines three issues concerning the function of the lexicon in word recognition, testing predictions of classes of theories that are divided on each issue: (1) whether or not lexical knowledge is used to facilitate speech perception; (2) which portion of a spoken word first makes contact with its representation in the lexicon; (3) the process by which a lexical entry is selected that best matches the speech signal. Experimental manipulations are designed to reveal the operation of the lexicon. Stimuli will consist of words and sentences, and the acoustic, phonological, and semantic characteristics of words will be varied. Multiple experimental tasks, such as phoneme monitoring, phoneme identification, and cross-modal priming, will be used to probe processing at different stages in the recognition system and to provide converging evidence on the issues that will be studied. Specialized computer hardware, software, and audio equipment will control stimulus construction, presentation and data collection. The findings should contribute to an understanding of the role of the lexicon in word recognition.
