基于空间与基于物体的视觉选择的交互作用

已有的大量实验证据表明,基于空间和基于物体的注意成分都存在于视觉系统中,两者并不是相互排斥的。然而,过去对基于空间和基于物体的视觉选择的研究是分别在非常不同的实验范式下进行的,从而导致对两种注意成分之间的内在关系的理论争论。本文介绍近十年来在单任务范式下对基于空间和基于物体的注意的内在关系的研究,并指出未来的研究应该重点从神经生理水平上揭示两种注意成分之间的交互作用关系。

The Interaction between Space-based and Objet-based Visual Selection

There is now clear evidence supporting the idea that both space-based and object-based components of attention are within the visual system,but not mutually exclusive.However,the evidence for these two components of visual attention came from very different paradigms,which results in the theoretical controversy on the inter-relations between space-based and object-based attention. This paper made a review of previous researches in which both space-based and objectbased components of attention were observed within the single task paradigm.The interaction between space-based and object-based attention in visual processing was discussed.At the end of the paper,it is proposed that future research should mainly investigate the interaction relationship between space-based and object-based visual selection at the neurophysiological level.
