视力是灵长类动物的一个决定性特征。人类可以以极快的呈现持续时间（短至 14 毫秒）处理视觉刺激。有证据表明，其他灵长类动物，包括黑猩猩和恒河猴，也能以类似的速度处理视觉信息。目前缺乏的是有关新世界猴子能力的信息，而这些信息对于确定灵长类动物是否存在快速处理能力或旧世界灵长类动物特有的能力是必要的。我们在计算机匹配样本范式上测试了卷尾猴（Cebus apella）和恒河猴（Macaca mulatta），以确定可以正确识别刺激的最短呈现持续时间。在研究 1 中，使用剪贴画图像，两个物种都实现了短至 25 毫秒的演示持续时间，同时保持了较高的准确率。在研究 2 中，我们使用亚洲语标字符来观察外观更相似的刺激是否会揭示物种差异。这两个物种都不像剪贴画图像那样准确，或者在演示持续时间短的情况下实现。特别是，在研究 2 中，卷尾猴最初的准确度低于恒河猴，但随着经验的积累，卷尾猴达到了相似的准确率和呈现持续时间。这些数据表明，快速视觉处理能力在灵长类动物谱系中广泛存在，并且所呈现的刺激形式可以对跨物种的处理产生影响。
Visual acuity is a defining feature of the primates. Humans can process visual stimuli at extremely rapid presentation durations, as short as 14 ms. Evidence suggests that other primates, including chimpanzees and rhesus macaques, can process visual information at similarly rapid rates. What is lacking is information on the abilities of New World monkeys, which is necessary to determine whether rapid processing is present across the primates or is specific to Old World primates. We tested capuchin (Cebus apella) and rhesus (Macaca mulatta) monkeys on a computerized matching-to-sample paradigm to determine the shortest presentation duration at which stimuli could be correctly identified. In Study 1, using clip art images, both species achieved presentation durations as short as 25 ms while maintaining high accuracy rates. In Study 2, we used logographic Asian language characters to see if stimuli that were more similar in appearance would reveal species differences. Neither species was as accurate, or achieved as short of presentation durations, as with clip-art images. In particular, capuchins were initially less accurate than rhesus in Study 2, but with experience, achieved similar accuracy rates and presentation durations. These data indicate that rapid visual processing abilities are widespread in the primate lineage, and that the form of the stimuli presented can have an effect on processing across species.
