研究顯示狗和人類對聲音感知有一致性

Remember the last time you scolded your dog？ He probably knew exactly what you meant. A new study shows that dogs and humans share a 1）cerebral link when it comes to vocal recognition. Using the same parts as human brains， little Fido is capable of recognizing voices and even determining their emotional tone.

Researchers at E？tv？s Loránd University measured the brain activity in 11 dogs and 22 humans， playing both dog barks and vocal samples during separate 2）MRIs for each subject. Unsurprisingly the tested dogs responded strongest to other dog barks and non-vocal environmental noises， while the human subjects almost all preferred the voice samples.

While the results aren’t ground-breaking， research leader Attila Andics says it’s an important finding.

Atilla： Dogs and humans use similar brain mechanisms to process social information. This is a first step to understand what makes vocal communication between dogs and humans so successful.

And cognitive 3）pathologist Marc Bekoff says the findings probably aren’t limited to pet dogs， telling Wired， “Certainly wolves， 4）coyotes and other undomesticated members of the 5）canine 6）genus are quite vocal and sensitive to emotion. Perhaps that’s why humans and dogs made such a good team.”

Since the research only included the Golden Retriever and Border Collie mix， the team hopes to test more 7）breeds in the future.

還記得你上次責(zé)備你的狗嗎？他可能清楚地知道你的意思。一項(xiàng)新的研究顯示：在聲音感知方面，狗和人類的大腦連接是一致的。小狗費(fèi)多動用與人類大腦的同一部分，能夠識別人的聲音，甚至辨別話語的情感語調(diào)。

來自匈牙利羅蘭大學(xué)的研究者對11只狗和22個人的大腦活動進(jìn)行測試，在對每個對象單獨(dú)進(jìn)行核磁共振的過程中，分別向測試對象播放狗吠和人聲樣本。意料之中的是，狗類實(shí)驗(yàn)對象對其他狗的叫聲以及無人聲環(huán)境下的噪音反應(yīng)最強(qiáng)烈，而幾乎所有人類實(shí)驗(yàn)對象都偏向于對人聲樣本做出強(qiáng)烈反應(yīng)。

該項(xiàng)研究的結(jié)論算不上是突破，但研究的負(fù)責(zé)人阿提拉·安迪克斯說，這是一個重要發(fā)現(xiàn)。

阿提拉：狗和人類運(yùn)用相似的大腦機(jī)制來處理交際信息。此項(xiàng)成果是理解人和狗之間如何能成功進(jìn)行聲音交流的第一步。

認(rèn)知病理學(xué)家馬克·貝科夫?qū)Α斑B線”網(wǎng)站說：“這一發(fā)現(xiàn)可能不限于寵物狗，也適用于狼、山狗以及其他未經(jīng)馴化的犬屬動物，他們對聲音和情感相當(dāng)敏感。也許這正是狗與人類相處融洽的原因。”

目前這項(xiàng)研究僅對黃金獵犬和邊境牧羊犬這兩個犬種進(jìn)行，研究團(tuán)隊(duì)希望在將來對更多的犬種進(jìn)行測試。
