特征捆绑机制的理论模型

捆绑问题被认为是认知科学和神经科学的中心问题之一，对心理过程的认知神经机制研究起到了重要推动作用。特征捆绑机制研究有认知和神经科学两大范式。特征整合论在认知理论中最具代表性，形式理论修正了其在错觉性结合测量等方面的不足，双阶段理论突出了前注意捆绑。时间同步性理论是影响最大的捆绑理论，神经网络模型为捆绑机制提出了更具体的结构模型。两大范式的整合及由低级认知过程向高级心理过程的深化可能是今后捆绑机制研究的重点

Theoretical Models on the Mechanisms of Feature Binding

Binding problem is regarded as one of the central themes of cognitive science and neuroscience. The research on feature binding has given a great impetus to studies on cognitive and neural mechanisms of many mental processes. There are two approaches to the research on the mechanisms of feature binding, that is, the cognitive paradigm and the neuroscience paradigm. Among the cognitive theories, Feature Integration Theory (FIT) is the most representative; the formal theory is characterized by its modification in the measurement of illusory conjunction and in other aspects that were not properly dealt with by FIT, while the two-stage theory bridges the gap between pre-attentive binding and post-attentive binding. The temporal synchronization theory in neurosicence has been the most influential theory on binding mechanisms up till now, whereas the newly proposed neural network model appears to provide a more specific insight into the neural mechanisms of feature binding. Two trends were predicted that the integration of cognitive paradigm and neuroscience paradigm and deepening from researches of binding in basic cognitive processes to those in high-level psychological processes might be the focus of relevant researches in the future.
