摘要
采用认知行为学实验方法,研究了视觉刺激的空间位置对人脑听觉信息处理的影响。实验刺激分为单通道听觉刺激、双通道视听觉位置一致刺激和不一致刺激,16名被试参与实验。实验任务分为判断听觉刺激方向和判断听觉刺激强度两种。实验结果发现任务为判断方向时,视觉刺激空间的不一致使反应速度降低正确率下降;任务与方向无关时,无论视觉刺激的位置与听觉刺激是否一致都促进听觉信息的判断。研究结果说明视觉刺激的空间位置对听觉信息处理的影响与实验任务相关,提出实验任务改变非注意通道信息的选择性注意的新观点。
The behavioral experiment was used to study the effect of spatial location of visual stimuli on auditory information processing. The experimental stimuli were divided into unimodal auditory stimuli,multimodal consistent audiovisual stimuli and inconsistent stimuli. Sixteen subjects participated the experiment. The experimental tasks were divided into two categories,determining the direction of auditory stimuli and judging the intensity of auditory stimuli. In the discretion task,inconsistent visual stimuli decreased reaction time and accuracy. In the detection task,response time to all audiovisual stimuli were both significantly faster than unimodal auditory stimuli.The experimental results showed that the spatial location of visual stimuli influenced on the auditory information processing that was related to the task. The viewpoint was proposed that experimental tasks changed the selective attention of unattentional information.
