| 摘 要： | 采用数字奇偶判断任务,以数字1-9(5除外)及汉字标签(左、右)作为实验材料,在视觉空间任务指令下探讨系统改变SOAs对数字-空间联结编码方式的影响。行为结果发现,SNARC效应以视觉空间编码方式为主,SOA为0ms并未出现SNARC效应; ERP结果发现,物理一致性在早期成分N1上的主效应显著。表明任务指导语影响SNARC效应的编码方式,其本质受词语信息标签加工程度的影响,且对SNARC效应的编码出现早期感觉阶段,SOAs与目标数字的特性影响SNARC效应的产生。

| Abstract: | Using parity judgement task,digit 1-9(except 5)and Chinese character label(left and right)as experimental materials,this study explored the influence of system changing SOAs on the coding mode of number-space interaction under the instruction of visual spatial task.The behavioral results showed that the main effect of SNARC was visual spatial coding,and there was no SNARC effect when SOA was 0 ms; ERP results showed that the main effect of physical consistency on the early component N1 was significant.The results show that task guide affects the encoding mode of SNARC effect,which is essentially influenced by the processing degree of word information labels,and the encoding of SNARC effect appears early sensory stage; the characteristics of SOAs and target number affect the generation of SNARC effect.The behavioral results showed that the main effect of SNARC was visual spatial coding,and there was no SNARC effect when SOA was 0 ms; ERP results showed that the main effect of physical consistency on the early component N1 was significant.The results show that task guide affects the encoding mode of SNARC effect,which is essentially influenced by the processing degree of word information labels,and the encoding of SNARC effect appears early sensory stage; the characteristics of SOAs and target number affect the generation of SNARC effect. |
