【摘要】：通过虚拟现实构建虚拟三维场景,将二维平面视觉空间返回抑制范式应用到三维空间,通过两个实验操纵了目标深度、线索有效性以及视野位置三个变量,考察注意在三维空间不同视野深度位置上进行定向/重定向产生的返回抑制效应。结果发现,(1)二次线索化位于固定的中央视野时,不论目标出现在近处空间还是出现在远处空间,外周视野条件下的返回抑制大于中央视野条件下的返回抑制;(2)二次线索化位于非固定的中央视野时,近处空间和远处空间的返回抑制存在分离,表现为当目标出现在远处空间时,外周视野条件下的返回抑制效应减小。研究表明,三维空间中外周视野深度位置上的返回抑制与中央视野深度位置上的返回抑制存在差异。
[Abstract]:Virtual 3D scene is constructed by virtual reality. The return suppression paradigm of two-dimensional planar visual space is applied to 3D space. Through two experiments, three variables, target depth, cue-validity and visual field position, are manipulated. The return inhibition effect of orientation / redirection at different depth of visual field in three dimensional space was investigated. The results showed that when the secondary cues were located in the fixed central visual field, whether the target appeared in the near space or in the distant space, The return inhibition under peripheral visual field is greater than that under central visual field.) when the secondary cues are located in the non-fixed central visual field, there is a separation between the return inhibition in the near space and the distant space. It is shown that when the target appears in the distant space, the return inhibition effect decreases under the condition of peripheral field of vision. The results show that there is a difference between the return suppression at the depth of the central visual field and the depth of the central visual field in three dimensional space.
