【摘要】:由刺激驅(qū)動(dòng)的注意選擇即為自下而上注意,又稱為瞬時(shí)注意或外源性注意。對(duì)其神經(jīng)機(jī)制的研究可使我們更好地理解大腦如何產(chǎn)生意識(shí)。自下而上選擇對(duì)注意的分配迅速且高效,但其神經(jīng)基礎(chǔ)一直存在爭(zhēng)論;仡櫫嗽撗芯款I(lǐng)域的兩大理論模型及其研究證據(jù):基于顯著性的注意模型和初級(jí)視皮層(V1)顯著性模型。最后討論了該領(lǐng)域未來(lái)的研究方向。
[Abstract]:Stimulus-driven attention selection is called bottom-up attention, also known as instantaneous attention or exogenous attention. The study of its neural mechanism could give us a better understanding of how the brain produces consciousness. Bottom-up selection distributes attention rapidly and efficiently, but its neural basis has always been debated. Two theoretical models and their evidences in this field are reviewed: the salient attention model and the primary visual cortex (V1) significance model. Finally, the future research direction of this field is discussed.
