Three monkeys performed a categorization task and a recognition task with briefly flashed natural images, using in alternation either a large variety of familiar target images (animal or food) or a single (totally predictable) target. The processing time was 20 ms shorter in the recognition task in which false alarms showed that monkeys relied on low-level cues (color, form, orientation, etc.). The 20-ms additional delay necessary in monkeys to perform the categorization task is compared with the 40-ms delay previously found for humans performing similar tasks. With such short additional processing time, it is argued that neither monkeys nor humans have time to develop a fully integrated object representation in the categorization task and must rely on coarse intermediate representations.
三只猴子对短暂闪现的自然图像进行分类任务和识别任务，交替使用各种各样熟悉的目标图像（动物或食物）或单个（完全可预测的）目标。在识别任务中，处理时间短20毫秒，其中误报表明猴子依赖低级线索（颜色、形状、方向等）。将猴子执行分类任务所需的额外20毫秒延迟与之前发现人类执行类似任务的40毫秒延迟进行比较。由于额外处理时间如此之短，有人认为猴子和人类在分类任务中都没有时间形成完全整合的物体表征，而必须依赖粗略的中间表征。
