Ponzo-like figures, with two parallel horizontal test lines superimposed on a pattern of converging background lines suggesting either a floor or a ceiling were presented in a tachistoscope unpredictably left or right of fixation, and the subjects had to compare the test lines as to length. The classical relative overestimation of the line closest to the apex of the background lines was obtained, but it was not stronger in the left visual field, as seemed to be predicted by at least two current generalizations concerning right hemisphere capacities: (a) that the right hemisphere is better at extracting spatial relations; (b) that its processing mode is more "holistic" and less "analytic" than that of the left hemisphere.
庞佐错觉图形，即两条平行的水平测试线叠加在暗示地面或天花板的汇聚背景线图案上，通过速示器呈现在注视点左侧或右侧的不可预测位置，受试者必须比较测试线的长度。得到了经典的、对最靠近背景线顶点的线条的相对高估结果，但在左视野中这种高估并不更强，而至少当前关于右半球能力的两条普遍观点似乎预测它会更强：（a）右半球更擅长提取空间关系；（b）其处理模式比左半球更“整体”、更不“分析”。
