Human adults decided whether a dot was nearer the top or bottom of rotated drawings of objects in a top-bottom task, and whether a dot was at the front of or behind rotated objects in a front-behind task. These two tasks were performed with the head upright and with the head tilted clockwise and counterclockwise in separate blocks of trials in order to dissociate retinal from environmental perceptual frames of reference. Response times increased approximately linearly with increasing departure from the orientation of the perceptual reference frame in both tasks and the magnitude of the effect was similar across tasks. In the head tilted conditions, the perceptual frame of reference was located midway between the environmental and retinal upright for both tasks.
在一项上下任务中，成年受试者要判断一个点是更靠近旋转物体图形的顶部还是底部；在一项前后任务中，要判断一个点是在旋转物体的前面还是后面。这两项任务分别在头部直立以及头部顺时针和逆时针倾斜的情况下进行，每次试验分块进行，目的是区分视网膜与环境感知参照系。在这两项任务中，反应时间都随着与感知参照系方向偏离程度的增加而大致呈线性增加，且效应的大小在两项任务中相似。在头部倾斜的情况下，两项任务的感知参照系都位于环境直立和视网膜直立的中间位置。
