Human brain can imagine and complete the words before they are uttered


Researchers have proven how the human brain thinks automatically in considering different possible meaning to the words before we've even heard the final sound of the word. Previous theories have proposed that listeners can only keep pace with the rapid pace of spoken language — up to five syllables per second — by anticipating a small subset of all words known by the listener, much like Google search anticipates words and phrases as you type.

The study was a team effort among former Rochester graduate student Kathleen Pirog Revill, now a postdoctoral researcher at Georgia Tech. "The best tool we have for brain imaging of this sort is functional MRI, but an MRI takes a few seconds to capture an image, so people thought it just couldn't be done,” a professor said.
