【摘要】 采用事件相关电位(ERP)探索字母识别过程中视听整合的神经机制。结果揭示,当刺激呈现在右视野时,整合差异波中存在两个显著的ERP成分:N136以及N262;当刺激呈现在左视野时,并没有显著的整合成分出现。该结果表明,呈现在右视野的视听字母信息更容易被整合。更多还原

【Abstract】 Our study used event-related potentials(ERPs) to investigate the neural mechanisms of auditory-visual integration in a letter identification task.The results revealded two significant ERP components in the difference waveform when stimuli were presented in the the right visual field,the N136 and the N262.While the stimuli were presented in the left visual field,no significant components occurred.The findings indicated that multimodal letter information presented in the right visual field could be integrated more effectively,compared with that presented in the left visual field.更多还原
