虽然对动物发声中与尺寸相关的声音变化的感知有充分的记录,但很少有人关注如何将这些信息与相应的视觉信息相结合。使用跨模式设计,我们测试了家犬将重新合成的大型犬或小型犬的典型咆哮声与尺寸匹配模型相匹配的能力。与观看不正确的模型相比,受试者观看尺寸匹配的模型的频率明显更高,持续时间也明显更长,这表明他们有能力将有关身体尺寸的信息从声学领域与适当的视觉类别联系起来。我们的研究表明,哺乳动物尺寸评估的感知和认知机制具有多感官性质,并需要进一步研究跨动物物种尺寸信息的多模式处理。
While the perception of size-related acoustic variation in animal vocalisations is well documented, little attention has been given to how this information might be integrated with corresponding visual information. Using a cross-modal design, we tested the ability of domestic dogs to match growls resynthesised to be typical of either a large or a small dog to size-matched models. Subjects looked at the size-matched model significantly more often and for a significantly longer duration than at the incorrect model, showing that they have the ability to relate information about body size from the acoustic domain to the appropriate visual category. Our study suggests that the perceptual and cognitive mechanisms at the basis of size assessment in mammals have a multisensory nature, and calls for further investigations of the multimodal processing of size information across animal species.
