采用选择性再认的方法考察在汉语词汇加工过程中, 视-听跨通道信息与视觉单通道信息加工过程中的抑制机制。结果表明: 对于视觉词汇的总体再认“否”反应 ,单通道干扰条件下的成绩优于跨通道干扰条件下的成绩。在视觉词汇加工过程中, 对外在干扰材料的抑制效率不受输入干扰刺激的通道的影响。抑制效率受干扰材料语义关系性的影响, 与目标材料属于同一语义范畴的比异范畴的干扰材料更难以被抑制。

The inhibitory mechanism in processing visual- auditory cross- modal and visual single- modal information during Chinese lexical processing was investigated in this study1 The selective recognition task was used. The subjects were required to selectively process visually presented target words and simultaneously to inhibit the accompanying distractors that were semantically relevant ( same category) or irrelevant ( different category) to targets in experimental conditions. In the control condition, the target was presented without distractor. Two modalities, visual or auditory modalities, were administered to distractors1 Each group of stimuli was followed by one probe1 The subjects were asked to recognize whether the probe was one of the targets just presented in the group. The inhibitory efficiency was evaluated by subtr acting the response performance in control condition from that in exper imental conditions1 The results showed that: During visual
Chinese lexical processing, the- no. recognition responses in the single- modal distracting condition ( visual distractors) was better than that in the cross- modal distracting condition( auditory distractors). The modality of distractors had no effect on the inhibitory efficiency in visual lexical processing1 The inhibitory efficiency was not significantly different between the two modalities of distractors, visual and auditory. The semantic relevance of the distracting materials had influence on inhibitory efficiency. The more semantic relevant (same category) to the target materials the distractors are, the more difficult they will be inhibited.
