发展性阅读障碍视听时间整合缺陷可能的机制:视听时间再校准能力受损

A possible mechanism for the audiovisual temporal integration deficits in developmental dyslexia: Impaired ability in audiovisual temporal recalibration

摘要:发展性阅读障碍的本质一直是研究者争论的焦点。大量研究发现,阅读障碍者具有视听时间整合缺陷。然而,这些研究仅考察了阅读障碍者视听时间整合加工的整体表现,也就是平均水平的表现,却对整合加工的变化过程缺乏探讨。视听时间再校准反映了视听时间整合的动态加工过程,对内部时间表征与感觉输入之间差异的再校准困难则会导致多感觉整合受损,而阅读障碍者的再校准相关能力存在缺陷。因此,视听时间再校准能力受损可能是发展性阅读障碍视听时间整合缺陷的根本原因。未来的研究需要进一步考察发展性阅读障碍者视听时间再校准能力的具体表现,以及这些表现背后的认知神经机制。

英文摘要:The nature of deficits of dyslexia has been under debate for a long time. A large number of studies have revealed that the dyslexics suffer from impaired audiovisual temporal integration. However, these studies only examined the overall performance of audiovisual temporal integration, and neglected to explore its dynamic process over time. Audiovisual temporal recalibration is an indicator describing the dynamic process of audiovisual temporal integration. Difficulty in recalibrating the differences between internal temporal representations and sensory inputs leads to impaired multisensory integration. Given that developmental dyslexics have deficits in recalibration-related abilities, the essence of the deficit in audiovisual temporal integration in developmental dyslexia may be impaired audiovisual temporal recalibration. Future studies could examine the specific performances of audiovisual temporal recalibration in developmental dyslexia, as well as its cognitive and neural mechanisms.
