启动效应通常伴随着相关脑区的神经活动的减少，这就是重复抑制现象：它已经成为探讨启动效应脑机制的关键。表征锐化和反应学习是近年来被广泛探讨的理论，它们分别从客体表征和反应生成两方面解释了重复抑制的成因以及重复抑制与行为改善之间的关系。本文围绕这两个理论，结合最近的研究，探讨了它们各自所对应的神经机制；进而讨论了它们各自的局限性以及未来研究的方向：另外，进一步阐述了启动效应脑机制的研究对脑成像和心理学研究带来的问题和挑战。

Behavioral priming often accompany reduction in neural activities in related brain areas involved in the initial processing of the stimulus. This phenomenon, called repetition suppression （RS）, becomes an key issue when it comes to exploring the brain mechanisms of behavioral priming. Representation sharpening and response learning are the most popular theories for explaining RS and its relation to behavioral benefits induced by repetition. In this article, we discussed both theories on their neural foundation and their limitations on the basis of recent researches and the open questions related to both theories, and the challenges to the imaging and behavioral studies by the findings of studies on brain mechanisms of priming.
