SPOKEN AND PRINTED WORD RECOGNITION IN DEAF ADULTS

研究的目的是调查观察到的个体差异。 在听力较好的人的口语和印刷单词识别中 减损。这项研究的长期目标是发现 心理语言加工系统受知觉经验的影响 并将这一知识应用于涉及感官辅助的治疗(即， 人工耳蜗术、助听器、触觉助听器)和交流 战略。本研究提出了两项考察加工通道的研究 (例如，语音与正字法)在口语和 印刷体单词识别。研究一验证了这样的假设 阅读中的语音编码是言语阅读能力的一种功能 有严重舌周听力障碍的个体。实验 我将使用词汇和语义决策技术来探索 音系学。研究二检验了这样的假设：那些使用 在印刷词识别过程中的音素代码可以很容易地 将印刷单词的知识转移到口语识别 版本。研究II将采用一项转移任务，在该任务中打印的伪 在程序的第一部分中学习单词，然后是口语 伪词学习。从纸质学习向口语学习的转变 被评估。据预测，一种独特的学习模式将 在参与者群体中得到遵守。研究I和研究的参与者 II将是听力正常的成年人和有舌周症状的成年人 严重的听力障碍。将在以下方面进行直接比较 三组成人全舌起病、听力深浅 有缺陷的人：经过测试的印刷品性能很高 单词词汇量和演讲阅读能力(HPHS)；高印刷 词汇和低语读能力(Hpls)；以及低印刷体词汇 和高级演讲阅读(LPHS)。对个人致病原因的认识 差异可以用来指导涉及感官辅助的治疗。 和沟通策略。

Research is proposed to investigate the individual differences observed in spoken and printed word recognition by people with profound hearing impairments. The long-term aims of the research are to discover how the psycholinguistic processing system is affected by perceptual experience and to apply this knowledge to therapies involving sensory aids (i.e., cochlear implants, hearing aids, tactile aids) and communication strategies. Two studies are proposed that examine processing-channel (i.e., speech versus orthography) relationships during spoken and printed word recognition. Study I tests the hypothesis that phonological code in reading is a function of speechreading ability in individuals with perlingual profound hearing impairment. Experiments will employ lexical and semantic decision techniques to probe use of phonology. Study II tests the hypothesis that individuals who make use of phonological codes during printed word recognition can readily transfer their knowledge of printed words to recognition of spoken versions. Study II will employ a transfer task in which printed pseudo- words are learned in the first part of the procedure, followed by spoken pseudo-word learning. Transfer from printed to the spoken learning will be assessed. It is predicted that a distinct pattern of learning will be observed across participant groups. Participants in Studies I and II will be adults with normal hearing and adults with perlingual-onset profound hearing impairments. Direct comparisons will be made among three groups of adults with perlingual-onset, profound hearing impairments, those with: tested performance that is high for printed word vocabulary and high for speechreading ability (HPHS); High printed vocabulary and low speechreading (HPLS); and low printed word vocabulary and high speechreading (LPHS). Knowledge about the causes of individual differences can be employed to guide therapies involving sensory aids and communication strategies.
