中央执行注意资源在消极和积极特征捆绑中的作用

鉴于以往研究未明确视觉工作记忆中特征捆绑是否需要注意资源，以及未考察积极加工条件下的特征捆绑等问题，本研究运用双任务干扰范式，通过两个实验分别在消极加工和积极加工条件下考察了联结客体的特征加工和特征捆绑，以及中央执行注意资源在特征捆绑中的作用。结果表明：联结客体的特征加工不但存在双重存储机制，还存在双重操作机制，这一结果拓展了Wheeler和Treisman（2002）的特征捆绑理论；联结客体的特征捆绑可分为消极特征捆绑和积极特征捆绑两种类型，消极特征捆绑不需要中央执行注意资源的参与，而积极特征捆绑则需要中央执行注意资源的参与。

The Role of Central Executive Attention Resource in Passive and Active Feature Binding

Previous studies are limited in investigating whether attention resource must be engaged for feature binding and how the feature binding occurs under the active process condition. Using double tasks interfere paradigm , two experiments were conducted to explore the feature process and feature binding of combination object and the role of central executive attention resource in feature binding under the passive process and the active process condition. This study demonstrates that both dual-storage mechanism and dual- manipulation mechanism exist in the feature orocess of combination object, and it expands the Wheeler and Treisman＇ s （2002） feature binding theory. The feature binding of combination object can be divided into passive feature binding and active feature binding. The passive feature binding does not need the central executive attention resource, while the active feature binding needs the central executive attention resource.
