Monkeys with bilateral posterior parietal and lateral frontal ablations were compared with normal animals on a series of four tests for their ability to relate elements of a visual pattern on the basis of the Gestalt principle of proximity. The operated animals showed no clear impairment on these tests of perceptual grouping. The three groups of monkeys were then trained to discriminate two faces and tested for generalisation to different views of the same faces. The pariental-operated monkeys showed less generalisation than the other animals to lateral mirror-images of the training stimuli, but more generalisation to inverted mirror-images. It is concluded that any deficit in "gestalt" perception following such lesions must be at a relatively high level.
对双侧顶叶后部和额叶外侧切除的猴子与正常动物进行了一系列四项测试，以比较它们基于接近性格式塔原则关联视觉模式元素的能力。手术动物在这些知觉分组测试中未表现出明显损伤。然后对三组猴子进行训练，使其区分两张脸，并测试对同一张脸不同视图的泛化能力。与其他动物相比，接受顶叶手术的猴子对训练刺激的侧镜反射图像的泛化能力较弱，但对倒置镜反射图像的泛化能力较强。得出的结论是，此类损伤后“格式塔”感知方面的任何缺陷一定处于相对较高的水平。
