n English, we can babble, bark, bleat, and bray. But we can also ask, cite, pose, preach and tell. Psychologist Steven Pinker thinks by studying how we use these verbs, we can learn a lot about what it means to be human. Join guest host Joe Palca in this hour of Science Friday for a talk with Pinker about his new book, "The Stuff of Thought: Language as a Window into Human Nature." Teachers, find more information about using Science Friday as a classroom resource in the Kids' Connection.
