This study examined the strategies used by monkeys lacking striate cortex to perform visual pattern discriminations. Complete bilateral removal of area 17 initially produced severe visual impairment with recovery of even rudimentary visual capacities (e. g., flux discrimination) dependent on gradually retraining the monkeys through a set of increasingly more complex pattern discriminations. After extended periods of postoperative testing, however, three of five monkeys lacking striate cortex were able to discriminate a number of complex visual patterns even when such local stimulus cues as amount of contour and number of elements were equal. Further testing demonstrated that these animals could distinguish a pattern's spatial organization. They were also able to transfer good performance to tasks with novel patterns.
本研究考察了缺乏纹状皮层的猴子用于进行视觉模式辨别的策略。完全双侧切除17区最初会导致严重的视力损害，即使是最基本的视觉能力（如光通量辨别）的恢复也依赖于通过一系列日益复杂的模式辨别对猴子进行逐步再训练。然而，经过长时间的术后测试，五只缺乏纹状皮层的猴子中有三只即使在诸如轮廓数量和元素数量等局部刺激线索相同的情况下，也能够辨别一些复杂的视觉模式。进一步的测试表明，这些动物能够区分模式的空间组织。它们还能够将良好的表现迁移到具有新图案的任务中。
