在一项关于大小恒定性的研究中，猴子接受了长时间的训练，以选择两个投射刺激圆盘中较大的一个，而与距离无关。当手术脑损伤后，术前培训，它被发现，后顶叶病变造成没有赤字在这项任务，而下颞叶病变造成严重的故障，其中四分之三的动物表现出几乎没有恢复。数学分析表明，下颞叶病变后的表现模式可以被描述为由于倾向于在一个“正确”和两个“不正确的策略”之间振荡，这种倾向在未手术的动物中也至少在一定程度上是明显的。有人认为，这两个不正确的策略可能是由于干扰的大小恒定性，使动物变得无法使用视网膜的大小和距离信息计算物理大小，而是使用视网膜的大小或距离信息单独。这种假设的知觉障碍与人类的某些临床障碍之间存在相似之处。
In a study of size constancy, monkeys were trained with extended practice to choose the larger of two projected stimulus discs independently of distance. When surgical brain lesions were made following pre-operative training, it was found that posterior parietal lesions caused no deficit on this task while inferotemporal lesions caused a severe breakdown from which three out of four animals showed almost no recovery. Mathematical analysis showed that the pattern of performance after inferotemporal lesions could be described as due to a tendency to oscillate between a “correct” and two “incorrect strategies” and that this tendency was also apparent to at least some extent in the unoperated animals. It is argued that the two incorrect strategies might have resulted from a disturbance of size constancy, such that the animal became unable to use both retinal size and distance information in computing physical size and instead used either retinal size or distance information alone. Parallels are drawn between such an hypothetical perceptual disorder and certain clinical disturbances in man.
