When we spill the beans to our dogs , it turns out they ’re listening jolly cautiously . According to astudyin the journalScience , dogs listen to both vocabulary and tone of voice , processing them together . That means your darling whelp is paying attention both to what you say and how you say it .
The New York Timesreports that Hungarian scientists latterly train a group of 13 extremely patient dogs to lie completely still in a MRI machine while the investigator value brain activity . scientist then played a voice transcription of a flight simulator saying positive phrases ( like “ unspoilt boy ” ) in a confirming tone of vocalisation , positive phrases in a neutral tone of voice , inert words ( like “ however ” ) in a positive tone of voice , and impersonal words in a achromatic step of part .
They found that the reward nitty-gritty in the canine volunteers ’ mind lit up importantly more when they heard confirming phrases in a electropositive tone . plus phrasal idiom in a neutral timbre and impersonal phrase in a positivistic tone did n’t have near the same impact . That is , hound translate look and vocabulary together . ( researcher mark that in cases where dog answer to owner enjoin meaningless or insulting word in a positive smell of vox , the dog are in all likelihood respond to body language . )
The squad also detect that dog-iron put more stock in language than pitch contour : While the left hemisphere of the brain is mostly responsible for interpret the signification of dustup , the right is responsible for interpreting intonation . depend at the MRI result , researcher observed a left hemisphere bias for process meaningful language independently of pitch contour — a bias humans also share .
The uncovering is significant , in part , because it shows that dogs — and possibly other beast — process terminology in much the same way as humans . They not only translate both tone and vocabulary together , but share a left-hand hemisphere preconception when it comes to communicating .
" Humans seem to be the only species which uses words and intonation for communicating emotion , touch sensation , intimate nation , " researcher Attila Andics tellsNPR . " To find that dog have a very similar nervous mechanics to tell apart meaningful quarrel from meaningless sound chronological succession is , I think , really amazing . "
