以为被试，通过两个实验考察了三维图形的方位变化对现象形态的影响。在实验一中，新奇的二维线图形首先在矢状面的一个方向上显示，然后在该平面上的一个改变的方向上测试对它们的识别。在实验II中，首次以1个方向展示了新颖的三维导线图形，并在围绕空间的三个主轴之一旋转后测试了对它们的识别。假设(A)形状知觉是图形描述过程的最终结果；(B)改变图形顶部、底部和侧面的感知位置的方向变化将影响图形的描述；以及(C)前后反转和绕Y轴旋转不会影响图形的描述，因为图形的正面和背面构成图形的两侧，并且所有图形侧面在现象上是相等的。除了在识别绕Y轴旋转90圈时产生的意想不到的影响外，研究结果支持这些假说。这种影响被视为知觉中自我中心主义的一个以前不为人知的例子，因为这种描述是由观察者的特定优势点产生的视网膜投影控制的。(参考文献9)(心理信息数据库记录(C)2016 APA，保留所有权利)
Two experiments with 64 undergraduates investigated the effect of change of orientation of figures in the 3rd dimension on phenomenal shape. In Exp I, novel 2-dimensional wire figures were first shown in 1 orientation in the sagittal plane, and recognition of them was then tested in an altered orientation in that plane. In Exp II, novel 3-dimensional wire figures were first shown in 1 orientation, and recognition of them was tested following rotation about one of the 3 major axes of space. It was hypothesized that (a) form perception is the end result of a process of figural description;(b) orientation change that alters the perceived location of the top, bottom, and side of a figure will affect this description; and (c) front-back reversal and rotations about the Y axis will not affect the description because front and back constitute the sides of a figure as much as left and right do, and all figural sides are phenomenally equivalent. Findings support these hypotheses except for an unanticipated effect on recognition of 90 rotations about the Y axis. This effect is seen as a previously unknown example of egocentrism in perception, since the description is governed by the retinal projection resulting from the particular vantage point of the observer.(9 ref)(PsycINFO Database Record (c) 2016 APA, all rights reserved)
