隐约可见的物体产生了重要的生态信号，在视觉和听觉领域都能被感知到。利用视觉和听觉刺激隐现和后退的优先观察技术，我们研究了恒河猴隐约刺激的多感觉整合。我们发现，对于一致的视觉和听觉隐现有强烈的注意偏好，但对于一致的刺激衰退没有类似的偏好。与之前的研究结果一致，这种影响只在音调刺激下发生，而不在宽带噪声下发生。这些结果表明，整合多感官隐约可见物体的能力已经进化。
Looming objects produce ecologically important signals that can be perceived in both the visual and auditory domains. Using a preferential looking technique with looming and receding visual and auditory stimuli, we examined the multisensory integration of looming stimuli by rhesus monkeys. We found a strong attentional preference for coincident visual and auditory looming but no analogous preference for coincident stimulus recession. Consistent with previous findings, the effect occurred only with tonal stimuli and not with broadband noise. The results suggest an evolved capacity to integrate multisensory looming objects.
