Recent studies on attention have emphasized distinctions between focused and distributed attention. Distributed attention has been shown to play a key role in obtaining statistical information or processing global aspects of a scene. In addition to differences in information processing, focused and distributed attention differ in terms of the way they interact with emotions. We review findings that indicate close relationship between focused attention and sad emotions as well as distributed attention and happy emotions. Given the potentially close relationship between attention and consciousness, these two types of attention may differ in terms of processes leading to awareness. We review different positions on the relationship between attention and consciousness and arguments for the existence of opposition between attention and awareness that have been made based on findings with color afterimages. We discuss our studies on attention and afterimages indicating the close linkage between different types of attention and awareness as indicated by differences in the strength of afterimages based on the type of attention deployed.
近期关于注意力的研究强调了集中注意力和分散注意力之间的区别。研究表明,分散注意力在获取统计信息或处理场景的全局方面起着关键作用。除了信息处理方式上的差异,集中注意力和分散注意力在与情绪相互作用的方式上也有所不同。我们回顾了一些研究结果,这些结果表明集中注意力与悲伤情绪、分散注意力与快乐情绪之间存在密切关系。鉴于注意力与意识之间可能存在的密切关系,这两种注意力在导致意识产生的过程方面可能存在差异。我们回顾了关于注意力与意识关系的不同观点,以及基于颜色后像的研究结果提出的注意力与意识之间存在对立关系的论点。我们讨论了我们关于注意力和后像的研究,这些研究表明,根据所采用的注意力类型,后像强度的差异表明不同类型的注意力与意识之间存在紧密联系。
