Forty subjects performed both of the following tasks. In the imagery task, simple dot patterns were presented for five seconds in free vision, followed by a three second fixation field. Subsequently, a circle was briefly presented in either the right or the left visual field and subjects were required to indicate whether or not the circle surrounded a point previously occupied by a dot. The perceptual task was similar except that the dot patterns remained on the screen while the circle was presented. Reaction times and error data indicated a left visual field advantage on the imagery task only, suggesting a right hemisphere superiority for extraction of spatial information from images.
40名受试者完成了以下两项任务。在表象任务中，简单的点图案在自由视觉中呈现5秒，随后是3秒的注视视野。随后，一个圆圈在右视野或左视野中短暂呈现，受试者需要指出该圆圈是否包围了之前由一个点占据的位置。知觉任务与之相似，只是在呈现圆圈时，点图案仍留在屏幕上。反应时间和错误数据表明，仅在表象任务中存在左视野优势，这表明右半球在从图像中提取空间信息方面具有优势。
