(Central) auditory processing disorder ((C)APD) is a controversial diagnostic category which may be an artefact of referral route. Yet referral route must, to some extent, be influenced by a child's profile of presenting symptoms. This study tested the hypothesis that parental perception of listening difficulty is associated with weaknesses in ability to sustain attention while listening to speech. Forty-four children (24 with listening difficulties) detected targets embedded in a 16-minute story. The targets were either mispronunciations or nonsense words. Sentence context was modulated to separate out effects due to deficits in language processing from effects due to deficits in attention. Children with listening difficulties missed more targets than children with typical listening abilities. Both groups of children were initially sensitive to sentence context, but this declined over time in the children with listening difficulties. A report-based measure of language abilities captured the majority of variance in a measure capturing time-related changes in sensitivity to context. Overall, the findings suggest parents perceive children to have listening, not language difficulties, because weaknesses in language processing only emerge when stressed by the additional demands associated with attending to, and processing, speech over extended periods of time.
(中枢)听觉处理障碍(APD)是一个有争议的诊断类别,可能是转诊途径的一个人为因素。然而,转诊途径在某种程度上必须受到孩子呈现症状的特征的影响。本研究检验了这样一个假设,即父母对听力困难的感知与在听言语时保持注意力的能力弱点有关。44 名儿童(24 名有听力困难)检测了嵌入在 16 分钟故事中的目标。目标是发音错误或无意义的词。句子语境被调整,以分离出由于语言处理缺陷引起的效果与由于注意力缺陷引起的效果。有听力困难的儿童比有典型听力能力的儿童错过的目标更多。两组儿童最初对句子语境都很敏感,但在有听力困难的儿童中,这种敏感性随着时间的推移而下降。基于报告的语言能力测量在捕捉对语境敏感性的时间相关变化的测量中捕捉到了大部分方差。总的来说,这些发现表明父母认为孩子有听力问题,而不是语言问题,因为只有在受到与长时间听和处理言语相关的额外需求的压力时,语言处理能力的弱点才会显现出来。
