'Mind Meld' Enables Good Conversation
from ScienceNOW Daily News
Why does human conversation come so easily? A new study chalks it up to a sort of "mind meld" between participants. Researchers have found that the brains of speakers and listeners become synchronized as they converse and that this "neural coupling" is key to effective communication.
Scientists have traditionally considered talking and listening to be two independent processes. The idea is that speech is produced in some parts of the brain, including a region known as Broca's area, and understood in others, including a region known as Wernicke's area. But recent studies suggest that there's actually much more overlap. For example, partners in a conversation will unconsciously begin imitating each other, adopting similar grammatical structures, speaking rates, and even bodily postures.
This overlap helps people establish a "common ground" during conversation and may even help them predict what the other is going to say next, argue psychologist Martin Pickering of the University of Edinburgh and psychologist Simon Garrod of the University of Glasgow, both in the United Kingdom. Some researchers think that so-called mirror neurons, which fire when one individual observes the actions of another, might be involved in these interactions.
