The effect of the distance between the center of the focus of attention and an unexpected stimulus on detection was examined in two experiments with the use of the inattentional-blindness paradigm [Mack and Rock, 1998 Inattentional Blindness (Cambridge, MA: MIT Press)]. In experiment 1, the closer a stimulus was to the center of attention, the more likely it was to be detected. Experiment 2 replicated this finding and controlled for retinal eccentricity. These results suggest that low-level stimulus characteristics (e.g. location) may play an important role in the detection of unexpected stimuli. The data are consistent with previous research on the spatial aspects of attention demonstrating that the distance to the focus of attention is a critical variable. This study demonstrates that the effect of distance is similar under conditions of inattention. Theories put forward to explain inattentional blindness should include 'early' attentional factors, as well as factors resulting from later stages of processing.
在两项使用无意视盲范式的实验中[麦克和洛克，1998年《无意视盲》（马萨诸塞州剑桥：麻省理工学院出版社）]，研究了注意力焦点中心与意外刺激之间的距离对检测的影响。在实验1中，刺激离注意力中心越近，就越有可能被检测到。实验2重复了这一发现，并控制了视网膜离心率。这些结果表明，低水平刺激特征（如位置）可能在意外刺激的检测中起重要作用。这些数据与先前关于注意力空间方面的研究一致，表明到注意力焦点的距离是一个关键变量。本研究表明，在注意力不集中的情况下，距离的影响是相似的。为解释无意视盲而提出的理论应包括“早期”注意力因素，以及后期加工产生的因素。
