Language outcome in children experiencing fluctuant hearing loss due to otitis media (OME) remains highly equivocal. In the current study, we assessed performance on highly sensitive verbal short-term memory (STM), new word learning and phonological processing tasks in 8-year-old children who had suffered from recurrent OME before the age of 3. Relative to a control group with no history of OME, we observed strictly normal performance for different STM and new word learning tasks. Performance on these tasks was also normally influenced by phonotactic, lexical and semantic variables. However, at the level of phonological processing, a small but significant decrease of performance was found in a speeded nonword identification task and a rhyme judgment task. The results of this study suggest that outcome of OME is characterized by subtle impairments at the level of perceptual-phonological analysis, but there is no significant impact on verbal STM and new word learning abilities.
As a result of this activity, the participant will be able to (1) explain the outcome of recurrent OME before age 3 on later language and verbal STM development, (2) be aware of the complex relationships that link language development and verbal STM, (3) explain how fluctuant hearing loss during infancy and early childhood could affect verbal STM development and learning capacity for new phonological information, (4) describe different verbal STM measures that distinguish retention capacities for phonological and lexico-semantic information, and (5) explain the influence of phonotactic frequency on nonword processing in language and verbal STM tasks.
由于中耳炎(OME)导致听力波动的儿童的语言发展结果仍存在很大争议。在本研究中,我们评估了3岁前患有复发性OME的8岁儿童在高度敏感的言语短期记忆(STM)、新词学习和语音处理任务上的表现。相对于无OME病史的对照组,我们观察到不同STM和新词学习任务的表现完全正常。这些任务的表现也正常地受到音位结构、词汇和语义变量的影响。然而,在语音处理层面,我们发现在快速非词识别任务和押韵判断任务中表现略有但显著下降。本研究结果表明,OME的结果表现为在感知语音分析层面存在细微损伤,但对言语STM和新词学习能力没有显著影响。
通过本次活动,参与者将能够(1)解释3岁前复发性OME对后期语言和言语STM发展的影响,(2)认识到将语言发展与言语STM联系起来的复杂关系,(3)解释婴儿期和幼儿期听力波动如何影响言语STM发展和新语音信息的学习能力,(4)描述区分语音和词汇语义信息保留能力的不同言语STM测量方法,以及(5)解释音位结构频率对语言和言语STM任务中非词处理的影响。
