这篇讲什么
匈牙利罗兰大学的研究团队用脑电图同时记录20名成人和20只家犬聆听连续语音流时的脑活动,发现两个物种对辅音结构语音流的词级神经同步都强于元音结构语音流。这种辅音偏好无法用声学显著性解释,因为元音携带的声学能量更强。研究还显示,即使在社会化关键期(出生后12至14周)之后才进入多语环境的狗也具备该偏好,提示辅音偏好可能源于对语音分布规律的统计学习,而非人类特有的语言表征。

Rácz1,2,4, Ivaylo Iotchev1#, Kitti Szabó1‡§, Attila Andics1,2,5* Across many human languages, consonants carry more lexical information than vowels. During speech segmentation, humans, unlike nonhuman primates, rely more on consonant than vowel patterns, despite vowels’ greater acoustic saliency. to investigate whether this consonant bias is specific to humans or could also emerge in other species exposed to human speech, we performed noninvasive electroencephalography in humans and dogs. Intertrial coherence measures of neural entrainment and event- related potentials revealed enhanced word- level tracking for consonant- compared with vowel- structured streams in both species. this suggests that dogs, similar to humans, exhibit consonant bias when segmenting the speech they hear. …
