许多群居动物对潜在的捕食者很敏感，这是它们反捕食者策略的一部分。警报呼叫的功能是阻止捕食者，并帮助其他群体成员发现危险。在许多脊椎动物中，左视野与探测潜在威胁或捕食者有关，但目前尚不清楚警报呼叫如何影响对潜在捕食者的视觉探测。在这里，我们通过实验研究了警报呼叫是如何自发地影响捕获的日本猕猴寻找潜在捕食者照片的。我们使用了一种视听偏好模式，即同时播放一条蛇和一朵花的图片，同时播放警报呼叫或接触呼叫的录音。我们发现，当回放通话时，两种图片类型的注视时间没有差异。如果蛇的图片出现在猴子视野的左侧，当警报信号被回放时，猴子看蛇的图片的时间要比看花的照片的时间长得多，这表明在处理捕食者表象的过程中，猴子的右半球有偏倚。这是动物左视野听觉增强视觉探测捕食者的第一次实验室演示，这将有助于更好地理解在野外进行的警报呼叫研究。
Many socially living animals are sensitive to a potential predator as part of their antipredator strategy. Alarm calls function to deter predators and to help other group members detect danger. The left visual field is involved in detection of potential threats or predators in many vertebrates, but it is unclear how alarm calls influence visual detection of a potential predator. Here, we experimentally examined how alarm calls spontaneously influence the search for pictures of a potential predator in captive Japanese macaques. We used an audiovisual preferential-looking paradigm by presenting pictures of a snake and a flower simultaneous with either a recording of alarm calls or contact calls. We found no difference in gaze duration between the 2 picture types when playing back contact calls. Monkeys looked significantly longer at pictures of snakes than at those of flowers when alarm calls were played back if the snake pictures were presented on the left side of the monkey’s visual field, indicating right hemispheric bias during processing of predator representations. This is the first laboratory demonstration of auditory enhancement of visual detection of predators in the left visual field in animals, which will contribute to a better understanding of alarm call studies conducted in the wild.
