人类和非人类动物的通信信号在自然界中经常被中断。多模态线索的一个优点是保持中断信号的显著性。我们研究了一种青蛙，它的叫声中自然会有无声的间隙。使用视频/音频回放，我们向雌性提供了中断的交配呼叫，有或没有同时的动态（即，充气和放气）声囊，并测试插入到差距中的多感觉提示（噪声和/或动态声囊）是否可以补偿中断的呼叫。我们发现，无论是将白色噪音插入到被中断的呼叫的无声间隙中，还是在同一间隙中显示动态声囊，都不能恢复呼叫的吸引力，相当于完整呼叫的吸引力。然而，在差距中同时呈现动态声囊沿着噪声，补偿了中断的呼叫，使其与完整的呼叫一样有吸引力。我们的研究结果表明，动态视觉囊补偿噪声干扰。这种新型的多感觉整合表明，多模式提示可以为噪音环境中不完美的发送者编码提供保障，并且多感觉整合对接收者的通信益处可能是有利于多模式信号进化的重要选择力。
Communication signals by both human and non-human animals are often interrupted in nature. One advantage of multimodal cues is to maintain the salience of interrupted signals. We studied a frog that naturally can have silent gaps within its call. Using video/audio-playbacks, we presented females with interrupted mating calls with or without a simultaneous dynamic (i.e., inflating and deflating) vocal sac and tested whether multisensory cues (noise and/or dynamic vocal sac) inserted into the gap can compensate an interrupted call. We found that neither inserting white noise into the silent gap of an interrupted call nor displaying the dynamic vocal sac in that same gap restored the attraction of the call equivalent to that of a complete call. Simultaneously presenting a dynamic vocal sac along with noise in the gap, however, compensated the interrupted call, making it as attractive as a complete call. Our results demonstrate that the dynamic visual sac compensates for noise interference. Such novel multisensory integration suggests that multimodal cues can provide insurance against imperfect sender coding in a noisy environment, and the communication benefits to the receiver from multisensory integration may be an important selective force favoring multimodal signal evolution.
