物体表征强度对基于动态物体的注意的影响

基于物体的注意已得到许多静态物体实验的证实, 然而, 对注意分配如何受动态物体影响的研究较少, 存在提示物体假设和动态更新假设两种观点。提示物体假设认为基于物体的注意由最初的物体决定, 而动态更新假设则认为由变化之后的物体决定。动态物体的注意研究还发现了即时物体效应, 即注意基于新物体进行。对于物体变化时注意究竟基于旧物体还是新物体, 新旧物体的相对物体表征强度在其中起决定作用; 当提示物体表征较强时表现为提示物体(即旧物体)决定注意分配, 而当即时物体表征较强时表现为即时物体(即新物体)决定注意分配。相对物体表征强度的概念对理解物体动态变化情况下基于物体的注意的分配以及解决相关理论之冲突可能有重要作用。

The role of object representation strength in the object-based attention of dynamic object

Object-based attention has been confirmed by many studies.However,most of the previous studies are based on static objects,and there are few studies on how object-based attention changes for dynamic objects.For the attentional allocation of dynamic object,there are two theoretical assumptions:the cued object hypothesis and the dynamic updating hypothesis.The cued object hypothesis proposes that object-based attention follows the original cued object,while the dynamic updating hypothesis assumes that object-based attention is determined by the changed object.The study of attention on dynamic objects also found the instantaneous object effect,which means the object-based attention follows the instantaneous object.We propose that experiments supporting the two theoretical hypotheses have differences in the experimental manipulation,which lead to changes in the relative strength between object representations of the cued object and the instantaneous object,resulting in the two seemingly contradictory points of view.The concept of the relative strength of object representation may be critical for understanding how object-based attention is allocated under the circumstance of processing dynamic objects.
