选择性注意的神经生理学解释

本文从听觉生理学的角度对以往的选择性注意理论模型进行宏观分析，提出了选择性注意的“多重选择理论”模型，并提供了相关的神经生理学理论依据。该模型进一步确认了人类选择性注意过程既存在着初期的过滤过程．也存在着其后的选择过程。认为在信息进入感觉器官之后．衰减的过程并不明显。同时通过丘脑的网状结构上行激动系统所具有只容许的单信息通过的门控功能，排除了能量分配理论中的关于大脑的能量分配限制的说法。

The Explanation of Neurophysiology for Selective Attention

The theoretical models on selective attention are analyzed based on aural-physlology. A multi-seleetive attention model is proposed on neorophysiology. The model shows that the process of selective attention includes initial filtering stage as well as selective stage thereafter. On the other hand, the model indicates that the information attenuation is unremarkable after information enters the sense organs. The model also shows that the meshwork is of gating function which allows single information through only. Therefore the theory of energy assigning limitation on the selective attention is questionable.
