先前的研究表明，视觉注意力可以通过两种不同的方式被引导到一个空间位置。注意力的分配可以是内源性的，以响应中央呈现的提示，也可以是外源性的，通过突然出现的视觉刺激来捕获。有人认为，外源性定向注意是一个自动的过程，而内源性定向注意代表了一个控制和战略的过程。M.I. Posner和C.R.R.斯奈德（Snyder，1975）认为，一个自动的过程发生时没有意图，不干扰其他心理过程，也不一定会引起意识，而一个受控的过程可能会干扰其他过程，并必然需要意图和意识。三个实验研究了意识在定向视觉注意中的作用。定向注意的内源性和外源性成分被放置在相互对立的评估外源性定向的自动性，通过检查潜在的短暂刺激事件，以捕获注意的主观意识的情况下。结果表明，一个外生线索低于主观阈值的意识捕获注意自动和无意识。
Previous research has shown that visual attention can be directed to a spatial location in 2 qualitatively different ways. Attention can be allocated endogenously in response to centrally presented precues, or it can be captured exogenously by a visual stimulus with an abrupt onset. It has been suggested that exogenous orienting of attention is an automatic process, whereas endogenous orienting elf attention represents a controlled and strategic process. M.I. Posner and C.R.R. Snyder (1975) suggested that an automatic process occurs without intention, does nor interfere with other mental processes, and does not necessarily give rise to awareness, whereas a controlled process will likely interfere with other processes and necessarily requires intention and awareness. Three experiments investigated the role of awareness in orienting visual attention. Endogenous and exogenous components of orienting attention were placed in opposition to each other to assess the automaticity of exogenous orienting by examining the potential for brief stimulus events to capture attention in the absence of subjective awareness. Results show that an exogenous cue presented below a subjective threshold of awareness captured attention automatically and without awareness.
