Three experiments of visual search for a cube (for a square pillar in Experiment 3) with an odd conjunction of orientation of faces and color (a cube with a red top face and a green right face among cubes with a green top face and a red right face, for example) showed that the search is made more efficient by arranging cubes (or square pillars) so that their top faces lie in a horizontal surface defined by pictorial cues. This effect shows the same asymmetry as that of the surface defined by the disparity cue did [Perception and Psychophysics, 62 (2000) 540], implying that the effect is independent of the three-dimensional cue and the global surface structure influences the control of attention during the search.
三项视觉搜索实验,搜索对象为一个立方体(实验3中为方柱体),其面的方向和颜色存在奇特的组合(例如,在顶面为绿色且右侧面为红色的立方体中,有一个顶面为红色且右侧面为绿色的立方体),实验表明,通过排列立方体(或方柱体),使其顶面位于由图形线索定义的水平面上,搜索效率会更高。这种效应与由视差线索定义的表面所产生的效应具有相同的不对称性[《知觉与心理物理学》,62 (2000) 540],这意味着该效应与三维线索无关,并且全局表面结构在搜索过程中会影响注意力的控制。
