观察者倾向于更快地对被中央呈现的面部注视的外围刺激做出反应，而不是对没有被注视的刺激做出反应。虽然这种凝视提示效应最初被视为反射性的，但也有一些迹象表明，自上而下的控制过程可能参与其中。因此，本研究采用双任务范式，试图破坏假定的控制过程中涉及的凝视线索。两个实验研究了工作记忆负荷对凝视线索的影响。在实验1中，参与者被要求在每次凝视试验期间在工作记忆中保持一组数字。在实验2中，凝视任务与听觉任务相结合，需要操纵和维护的视觉空间信息。观察到凝视提示效应，但它们在两个实验中都没有受到双任务负荷的调制。这些结果是一致的传统帐户的凝视提示作为一个高度反射的过程。
Observers tend to respond more quickly to peripheral stimuli that are being gazed at by a centrally presented face, than to stimuli that are not being gazed at. While this gaze-cueing effect was initially seen as reflexive, there have also been some indications that top-down control processes may be involved. Therefore, the present investigation employed a dual-task paradigm to attempt to disrupt the putative control processes involved in gaze cueing. Two experiments examined the impact of working memory load on gaze cueing. In Experiment 1, participants were required to hold a set of digits in working memory during each gaze trial. In Experiment 2, the gaze task was combined with an auditory task that required the manipulation and maintenance of visuospatial information. Gaze cueing effects were observed, but they were not modulated by dual-task load in either experiment. These results are consistent with traditional accounts of gaze cueing as a highly reflexive process.
