It is now well-established that there is a causal connection between children's phonological skills and their acquisition of reading and spelling. Here we study low-level auditory processes that may underpin the development of phonological representations in children. Dyslexic and control children were given a battery of phonological tasks, reading and spelling tasks and auditory processing tasks. Potential relations between deficits in dyslexic performance in the auditory processing tasks and phonological awareness were explored. It was found that individual differences in auditory tasks requiring amplitude envelope rise time processing explained significant variance in phonological processing. It is argued that developmentally, amplitude envelope cues may be primary in establishing well-specified phonological representations, as these cues should yield important rhythmic and syllable-level information about speech.
现在已经充分证实,儿童的语音技能与其阅读和拼写能力的习得之间存在因果联系。在此,我们研究可能支撑儿童语音表征发展的低层次听觉过程。对患有诵读困难症的儿童和对照组儿童进行了一系列语音任务、阅读和拼写任务以及听觉处理任务。探讨了听觉处理任务中诵读困难表现的缺陷与语音意识之间的潜在关系。研究发现,在需要处理振幅包络上升时间的听觉任务中的个体差异,在语音处理方面解释了显著的方差。有人认为,从发育角度来看,振幅包络线索在建立明确的语音表征方面可能是首要的,因为这些线索应该会产生有关语音的重要节奏和音节层面的信息。
