尺寸距离不变性假设（SDIH）进行了检查的记忆和图像刺激。在实验1中，受试者给出了熟悉物体的记忆距离和想象距离，以及无法描述的杆的想象距离。所述大小和距离之间的关系由指数小于1的幂函数比由更受限制的SDIH（指数1）更充分地描述。在实验2中，受试者回忆和成像熟悉的物体的距离估计，并描述了每个受试者所处的视觉环境。另一个小组则根据一般相似性将上下文分类。基于记忆的距离估计和基于图像的距离估计之间没有显着差异，并且视觉上下文没有根据它们是在记忆中还是在图像条件下产生而进行排序。在实验3中，受试者估计在户外设置的对象的距离。估计和物理距离之间存在线性关系，这表明实验1和2中获得的较低指数不是距离判断程序的伪影。
The size-distance invariance hypothesis (SDIH) was examined for remembered and imaged stimuli. In Experiment 1, subjects gave remembered and imaged distances of familiar objects and imaged distance of nondescript rods. The relationship between stated size and distance is more adequately described by power functions with exponents less than 1 than by the more restricted SDIH (exponent 1). In Experiment 2, subjects gave distance estimates to recalled and imaged familiar objects and described the visual context in which each subject was situated. A different group then sorted the contexts into categories based on general similarity. There were no significant differences between distance estimates based on memory and those based on imagery, and the visual contexts were not sorted according to whether they were generated in the memory or in the imagery conditions. In Experiment 3, subjects estimated the distances to objects in an outdoor setting. A linear relationship was found between estimated and physical distance, suggesting that the lower exponents obtained in Experiments 1 and 2 were not artifacts of the distance judgment procedure.
