Dogs' brains cannot distinguish words that differ by a single speech sound, such as "sit" versus "set."

강아지가 유사단어를 구분할 수 없는 이유 개의 뇌는 'sit' 대 'set'처럼 하나의 말소리로 유사한 다른 단어를 구별할 수 없다." 아마도 개가 앉거나 발을 내미는 것을 배울 때 가장 똑똑하다고 생각할 것이다. 하지만 대부분의 개들은 제한된 수의 단어만 집어낼 수 있다. 이 연구는 개의 뇌가 "dig" 대 "dog" 또는 "sit" 대 "set"와 같이 유사단어를 구별할 수 없다는 것을 발견했다. 이것은 개들이 비슷한 소리를 가진 단어들을 구별하지 못하는 인간의 유아들과 유사하다. 그러나 14~20개월쯤 되면 아기들은 일반적으로 한 단어의 모든 소리가 중요하다는 것(즉, "개"와 "디그"는 다른 단어라는 것)을 배우기 시작하며, 이것은 그들의 어휘력을 치솟게 한다고 저자들은 말했다. 개들은 이러한 구별을 절대 이해하지 못하는 것 같다. 헝가리의 Eövös 로란트 대학 윤리학부의 수석 저자인 아틸라 앤딕스는 성명에서 "개들은 말을 들을 때 모든 세부적인 언어에 주의를 기울이지 않을 수 있다"고 말했다. "더 많은 연구를 통해 이것이 개들이 상당한 어휘를 습득하는 것을 무력화하는 이유가 될 수 있는지 밝혀낼 수 있을 것이다." 황기철 콘페이퍼 에디터 Ki Chul Hwang Conpaper editor curator |

You probably think your dog is the smartest (and cutest!) when they learn to sit or give a paw. But most dogs can pick up only a limited number of words in their lives, and a new study may help explain why.

The study found that dogs' brains cannot distinguish words that differ by a single speech sound, such as "dig" versus "dog," or "sit" versus "set." This makes dogs similar to human infants, who also can't distinguish between words with similar sounds. But around age 14 to 20 months, babies typically start to learn that every sound in a word matters (i.e. that "dog" and "dig" are different words), and this allows their vocabulary to soar, the authors said.
It appears that dogs never grasp these distinctions. "Dogs might not attend to all details of speech sound when they listen to words," study senior author Attila Andics, of the Department of Ethology at Eötvös Loránd University in Hungary, said in a statement. "Further research could reveal whether this could be a reason that incapacitates dogs from acquiring a sizable vocabulary."

For the study, published Tuesday (Dec. 8) in the journal Royal Society Open Science, the researchers monitored the brain waves of 17 very good dogs using a technique called electroencephalography (EEG). The study is one of the first to use EEG on awake dogs that didn't have any specific training. The dogs visited the lab with their owners, and once the dogs got used to the new environment, they sat down on a mattress with their owners, and the researchers attached electrodes to the dogs' heads with tape.
