Abstract

Impairments of auditory processing are among frequent findings in dyslexia. However, it is unclear how auditory signals are gated from brainstem to higher central processing stages in these individuals. The present study was done to investigate auditory sensory gating in children with developmental dyslexia (DD), and to determine whether sensory gating correlates with performance on behavioural tasks. Auditory sensory gating at P50, N1 and P2 waves was evaluated in two groups including 20 children with DD and 19 children with typical reading development (TRD). Behavioural tests were used to evaluate phonological working memory (PWM) and selective attention abilities. Sensory gating in children with DD was significantly less efficient than their peers at P50, N1 and P2 waves. Lower auditory evoked potential (AEP) amplitudes were found in the DD group. The children with TRD scored better in all the behavioural tests. Relationships were reported between sensory gating at P50, N1, P2 and behavioural performance in the two groups. Children with dyslexia had deficient sensory gating in comparison with controls. In addition, children with dyslexia experienced problems with PWM and selective attention tasks. The function of sensory gating was associated with attentional and PWM performances in this group.

发育性阅读障碍儿童听觉感觉门控的非典型功能:研究其与认知能力的关系。
听觉加工障碍是阅读障碍的常见表现之一。然而,目前尚不清楚这些人的听觉信号是如何从脑干进入高级中枢处理阶段的。本研究旨在研究发育性阅读障碍(DD)儿童的听觉感觉门控,并确定感觉门控是否与行为任务的表现相关。在两组中评估P50、N1和P2波的听觉感觉门控,包括20名DD儿童和19名典型阅读发展(TRD)儿童。行为测试用于评估语音工作记忆(PWM)和选择性注意能力。DD儿童的感觉门控在P50、N1和P2波时的效率明显低于同龄人。DD组的听觉诱发电位(AEP)振幅较低。患有TRD的儿童在所有的行为测试中得分都更好。据报道,两组P50、N1、P2的感觉门控与行为表现之间存在关系。与对照组相比,患有阅读障碍的儿童存在感觉门控缺陷。此外,患有阅读障碍的儿童在PWM和选择性注意力任务方面也遇到了问题。感觉门控功能与该组的注意和PWM表现有关。

期刊介绍: DYSLEXIA provides reviews and reports of research, assessment and intervention practice. In many fields of enquiry theoretical advances often occur in response to practical needs; and a central aim of the journal is to bring together researchers and practitioners in the field of dyslexia, so that each can learn from the other. Interesting developments, both theoretical and practical, are being reported in many different countries: DYSLEXIA is a forum in which a knowledge of these developments can be shared by readers in all parts of the world. The scope of the journal includes relevant aspects of Cognitive, Educational, Developmental and Clinical Psychology Child and Adult Special Education and Remedial Education Therapy and Counselling Neuroscience, Psychiatry and General Medicine The scope of the journal includes relevant aspects of: - Cognitive, Educational, Developmental and Clinical Psychology - Child and Adult Special Education and Remedial Education - Therapy and Counselling - Neuroscience, Psychiatry and General Medicine
