五岁日本猴子接受了长期视觉识别记忆测试。使用的物体是他们在生命的头两年中每天遇到的那些作为要记住的刺激物：人、同伴和地方。延迟三年后，我们使用优先观看范式进行了识别测试，其中向猴子展示了这些熟悉刺激的图片以及新刺激的图片。与新刺激物相比，猴子观看熟悉刺激物的图片的时间相对较长，而从未见过相关刺激物的对照组参与者则没有表现出任何歧视性偏好。因此，猴子通过图片认出了熟悉的刺激，这表明即使在延迟了三年之后，它们仍然保留了生活中遇到的真实物体的视觉信息。我们目前的研究结果证实了猴子的长期视觉识别能力，这可能对于具有生态和社会意义的行为（例如个体识别）至关重要。 (C) 2011 年 Wiley 期刊公司。Dev Psychobiol 53：732-737，2011。
Five-year-old Japanese monkeys were tested on long-term visual recognition memory. The objects used were those that they had encountered daily during their first 2 years of life as to-be-remembered stimuli: persons, peers, and places. After a 3-year delay, we conducted a recognition test using the preferential looking paradigm where the monkeys were presented with pictures of these familiar stimuli in combination with those of novel stimuli. The monkeys looked relatively longer at pictures of familiar stimuli than at those of novel stimuli, while participants in the control group, who had never seen the stimuli in question, showed no discriminative preference. The monkeys thus recognized the familiar stimuli through the pictures, suggesting retention of visual information on real objects encountered in their lives even after a 3-year delay. Our present findings confirmed long-term visual recognition in monkeys, which might be essential to ecologically and socially significant behaviors such as individual identification.
