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 of 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 not 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.
