摘　　要： 通过探讨视空间和语义通道内的注意资源的限制对IOR的影响的4个实验,来验证“IOR的低级成分不受注意资源限制的影响和IOR的高级成分受注意资源限制的影响”的假设。实验1A和1B的结果表明,在基于空间位置的简单检测任务中,IOR的低级成分既不随语义通道内注意资源的减少而消减,也不随空间通道内注意资源的减少而消减。实验2A和2B结果表明,在基于客体特性的辨别任务中,IOR的高级成分既随语义通道内注意资源的减少而消减,又随空间通道内注意资源的减少而消减。因此,辨别任务中的IOR受一般性注意资源的限制。同时,实验结果还表明,IOR的高级成分对空间通道内的注意资源的需求要高于对语义通道内注意资源的需求。 By exploring the effect of memory load on IOR, 4 experiments systematically tested the hypothesis that the lower component of IOR is free of attention capacity limits, while its counter part is limited by the attention capacity. Experiment 1A and 1B showed that IOR did not disappear with either the semantic or the spatial attention capacity reduction in the spatial -based simple detection tasks. While experiment 2A and 2B showed that the higher component of IOR disappeared with both the semantic and the spatial attention capacity reduction in the color discrimination tasks, so it is limited by the general attention capacity. Meanwhile the results also suggested that the higher component of IOR has much more demands on the attention capacity in the spatial channel than in the semantic channel.
