A mechanistic understanding of attention is necessary for the elucidation of the neurobiological basis of conscious experience. This chapter presents a framework for thinking about attention that facilitates the analysis of this cognitive process in terms of underlying neural mechanisms. Four processes are fundamental to attention: working memory, top-down sensitivity control, competitive selection, and automatic bottom-up filtering for salient stimuli. Each process makes a distinct and essential contribution to attention. Voluntary control of attention involves the first three processes (working memory, top-down sensitivity control, and competitive selection) operating in a recurrent loop. Recent results from neurobiological research on attention are discussed within this framework.

注意的基本组成部分。

对注意力的机械理解对于阐明意识体验的神经生物学基础是必要的。本章提供了一个思考注意的框架，该框架有助于从基础神经机制的角度对这一认知过程进行分析。需要注意四个基本过程：工作记忆，自上而下的敏感性控制，竞争性选择以及针对显着刺激的自下而上的自动过滤。每个过程都对关注做出了独特而重要的贡献。自愿的注意力控制涉及循环循环中的前三个过程（工作记忆，自上而下的敏感性控制和竞争性选择）。在此框架内讨论了有关注意力的神经生物学研究的最新结果。
