Dogs Know More than We Knew
(p. A1) Dr. Andics, who studies language and behavior in dogs and humans, along with Adam Miklosi and several other colleagues, reported in a paper to be published in this week's issue of the journal Science that different parts of dogs' brains respond to the meaning of a word, and to how the word is said, much as human brains do.
. . .
A trainer spoke words in Hungarian -- common words of praise used by dog owners like "good boy," "super" and "well done." The trainer also tried neutral words like "however" and "nevertheless." Both the praise words and neutral words were offered in positive and neutral tones.
The positive words spoken in a positive tone prompted strong activity in the brain's reward centers. All the other conditions resulted in significantly less action, and all at the same level.
. . .
In terms of evolution of language, the results suggest that the capacity to process meaning and emotion in different parts of the brain and tie them together is not uniquely human. This ability had already evolved in non-primates long before humans began to talk.
