Us dog mums and dads have known this fur-ever but now we have science to back it up. Its no wonder before the word “WALKIES!!” is even finished, heads tilt, ears perk and tails wag. This study has confirmed that our best friends respond to positive words and intonation over neutral and negative intonation. This is why positive reinforcement is key when toilet training vs negative reactions.
Scientists have come up with proof that shows dogs not only understand human language, but also know the difference between genuine praise and meaningless words.
The research was conducted at the Eotvos Lorand University in Budapest, where they scanned the brains of 13 dogs trained to lie in MRI scanners and monitored what happened as they listened to their owners speak to them.
Dr Attila Andics, who led the study, said it confirmed that just like humans, dogs used different parts of the brain to understand language.
“We’ve found that in dog brains, very similarly to what was found in the human brain, the left hemisphere is more involved in processing meaningful words,” he said.
“We’ve found the right hemisphere auditory brain region will respond differently to praising intonation and neutral intonation, independently of word meaning.”
That means the dogs only registered they were being praised when both the words and intonation were positive.
Experiment offers a clue to when humans started using words
Dr Andics was most excited by what the experiment revealed about how and when humans developed language.
He said the findings suggested the mental ability to process language evolved in humans earlier than previously thought.
“There’s no special neuron mechanism, it seems from this study, in humans that made us able to start using words. It’s something else, it has to be something else,” Dr Andics said.
“Because the neural mechanism is there in dogs as well.
“It seems that the ‘big boom’, if anything, is the actual invention of humans to start using words.
“The very idea that we can use words, and not only intonation, to communicate our feelings.”
