意大利帕尔玛大学的动物行为学家埃莱奥诺拉·比菲领导的一项研究发现，狗可能与人类一样，将特定的声音与特定的形状联系起来。1研究人员对70只家犬进行了两项实验，使用音频和图像组合测试，通过人工智能追踪狗的注视方向。1结果表明，狗在听到"Bouba"时更多地看向圆形物体，而听到"Kiki"时则更多地看向尖刺形物体。1
为了排除无关因素的干扰，研究人员在第二项实验中让狗主人戴上耳机播放摇滚乐，以消除主人可能无意中发出的线索对狗行为的影响。1该研究已发表在《英国皇家学会学报B：生物科学》上。1
Researchers at the University of Parma have discovered that dogs, like humans, appear to associate the nonsense word "bouba" with round shapes and "kiki" with spiky ones.1 The study, led by animal behaviorist Eleonora Biffi, tested 70 domestic dogs using a combination of audio and visual stimuli, with artificial intelligence tracking where the dogs looked in response to each word.1 When hearing "bouba," dogs gazed more frequently toward round images, while "kiki" prompted them to look toward angular, spiky shapes.1
The research involved two separate experiments, with 51 dogs participating in the first phase and 19 in the second.1 In the second experiment, owners wore headphones playing rock music to eliminate any unintentional behavioral cues they might inadvertently convey to their animals.1 The findings, published in the Proceedings of the Royal Society B: Biological Sciences, suggest a potential shared mechanism between humans and dogs in how they process associations between sound and visual form, offering a starting point for exploring how canines may comprehend human language at a deeper level.1
