Although visual attention is one of the most thoroughly investigated topics in experimental psychology and vision science, most of this research tends to be restricted to the near periphery. Eccentricities used in attention studies usually do not exceed 20° to 30°, but most studies even make use of considerably smaller maximum eccentricities. Thus, empirical knowledge about attention beyond this range is sparse, probably due to a previous lack of suitable experimental devices to investigate attention in the far periphery. This is currently changing due to the development of temporal high-resolution projectors and head-mounted displays (HMDs) that allow displaying experimental stimuli at far eccentricities. In the present study, visual attention was investigated beyond the near periphery (15°, 30°, 56° Exp. 1) and (15°, 35°, 56° Exp. 2) in a peripheral Posner cueing paradigm using a discrimination task with placeholders. Interestingly, cueing effects were revealed for the whole range of eccentricities although the inhomogeneity of the visual field and its functional subdivisions might lead one to suspect otherwise.
尽管视觉注意力是实验心理学和视觉科学中研究最为深入的课题之一，但大多数此类研究往往局限于近周边视野。注意力研究中所使用的离心率通常不超过20°至30°，但大多数研究甚至采用的最大离心率要小得多。因此，关于超出此范围的注意力的实证知识较为匮乏，这可能是由于此前缺乏合适的实验设备来研究远周边视野的注意力。由于能够在远离心率下显示实验刺激的高时间分辨率投影仪和头戴式显示器（HMD）的发展，这种情况目前正在改变。在本研究中，使用带有占位符的辨别任务，在周边波斯纳线索范式中，对近周边视野之外（实验1为15°、30°、56°）和（实验2为15°、35°、56°）的视觉注意力进行了研究。有趣的是，尽管视野的不均匀性及其功能细分可能会让人产生相反的怀疑，但在整个离心率范围内都揭示了线索效应。
