  • Well, the answer's not entirely clear,

    目前為止還沒有明確的答案,

  • and there hasn't been any peer-reviewed research about it.

    且也沒有經過專家審核的研究出現

  • But a couple scientists hypothesize that head-tilting might help dogs see and hear us better.

  • One popular idea comes from a 2013 blog posted by a psychologist named Stanley Coren,

  • When you speak to someone, dog or otherwise,

  • you express a lot of emotion with the lower half of your face.

  • But a dog with a bigger muzzle might not be able to see your smile or frown clearly,

    但有較大吻部的狗可能沒有辦法清楚地看見你笑或皺眉

  • so Coren suggests that tilting helps them get a better view.

    所以 Coren 假設歪頭可以幫助它們看得更清楚

  • He tested this idea by surveying 582 dog owners online,

    為了測試這個理論,他在線上調查了 582 位狗主人

  • asking them to describe about their dog's breed or head shape,

    詢問他們自己狗狗的品種或是頭型

  • then to rate how frequently their dogs do the head tilting thing.

    並請他們算算看他們的狗狗歪頭的頻率

  • The data were split into two groups.

    資料結果分成兩組

  • One was brachycephalic dogs with flatter faces like pugs.

    一組是臉較扁的短吻犬,例如巴哥

  • And the other was a mix of mesaticephalic dogs with medium muzzles like beagles

    另一組則是吻部大小中等的狗,如米格魯

  • and dolichocephalic dogs with long noses like greyhounds.

    以及有長鼻子的長吻犬,像是格雷伊獵犬

  • In Coren's survey, 71% of owners of bigger-muzzled dogs reported that

  • their pupsfrequently,"“most of the time,” oralwaystilt their heads when spoken to,

  • as opposed to only 52% of owners of smaller-muzzled dogs.

    相較之下,僅有52%的短吻犬主人回答在相同情況下狗狗會歪頭

  • That, he says, is a statistically significant difference.

    Coren 認為這個數據上的差異相當地重要

  • But 52% is still a lot of dogs, so this probably isn't the whole story.

    但52%也是相當高的比率,所以真相可能不僅於此

  • A psychologist who runs a dog cognition lab named Alexandra Horowitz thinks that

    一位經營狗狗認知實驗室的心理學家 Alexandra Horowitz 認為

  • dogs could be trying to hear us better with those sideways looks.

    狗狗歪頭可能是在嘗試更清楚地聽見我們的聲音

  • Specifically, she thinks they're tilting their heads to adjust the floppy parts of their ears,

    她認為狗狗歪頭是為了調整他們耳朵軟軟的區塊---

  • called pinnae, to get a better sense of where sounds are coming from.

  • A third take from a dog trainer named Steven Lindsay is that dogs tilt their heads because

    有一位狗狗訓練師 Steven Lindsay 則認為狗狗歪頭是因為

  • one part of their brain is involved in both listening and body language.

    他們腦袋的一部分區塊同時包含了聽覺及肢體語言

  • We think a region called the nucleus ambiguous

    我們認為有一個稱為疑核的部位

  • controls a dog's head movements, as well as the muscles in a dog's middle ear

    控制著狗狗的頭部運動,以及狗狗中耳的肌肉

  • that help it perceive subtly different sounds.

    中耳可以幫助狗狗辨認不同細微的聲音

  • So Lindsay suggests that when your pup is listening,

    所以 Lindsay 認為當你的狗狗正在聽你說話時

  • it can't help but show you with its body too.
