File under: research that comes to a blatantly obvious conclusion that everyone already was aware of:
Researchers at Eötvös Loránd University in Budapest measured the brain activity of family dogs using a technique called electroencephalography, which involved taping electrodes to the animals' heads.
The researchers played the dogs recorded instruction words they knew (such as "sit"), similar but nonsense words ("sut"), and then, very different nonsense words ("bep").
Experts found that dogs, who had not been specifically trained for the experiment, could quickly and clearly tell the difference between the known instruction words and the very different nonsense words...However, the animals did not pay attention to the small differences between known words and similar-sounding nonsense words. Instead, the canine study subjects processed them as the same word,
"it seems like they don't really pay attention to all of the speech sounds," [the researcher] said, adding that further research could explain why...the study also confirmed that dogs actually listen to human speech, as suggested by previous studies -- and don't just respond to familiar humans or body language.
You might think your dog understands every word you say to him -- but chances are he isn't hanging on your every word, a new study has found.
