Using visually complex stimuli, three monkeys learned visual exclusive-or (XOR) tasks that required detecting two way visual feature conjunctions. Monkeys with passive exposure to the test images, or prior experience, were quicker to acquire an XOR style task. Training on each pairwise comparison of the stimuli to be used in an XOR task provided nearly complete transfer when stimuli became intermingled in the full XOR task. Task mastery took longer, accuracy was lower, and response times were slower for conjunction stimuli. Rotating features of the XOR stimuli did not adversely effect recognition speed or accuracy.
通过使用视觉上复杂的刺激物，三只猴子学会了视觉异或（XOR）任务，该任务需要检测双向视觉特征联结。被动接触测试图像或有先前经验的猴子能更快地掌握异或风格的任务。对异或任务中要使用的刺激物进行每对比较的训练，当刺激物在完整的异或任务中混合时，能提供几乎完全的迁移。对于联结刺激物，掌握任务所需时间更长，准确率更低，反应时间更慢。异或刺激物的旋转特征不会对识别速度或准确率产生不利影响。
