A crew from "Good Morning America: some subjects being run especially for the occasion of and an interview with Bob Krauss in his office, talking about the gestural facilitation of speech.
The clip on the left shows Ezequiel Morsella's electromyographic study of forearm muscle activation as it relates to the conceptual content of speech. Ezequiel, Jennifer Kim and Lauren Walsh are visible (very briefly) early in the clip. In the one on the right, Bob Krauss tells a lame joke his grandfather told him, which he claims is the origin of the lexical gesture hypothesis. (Don't believe it.)
For the reaction of the show's co-hosts (Lisa McKree and Hal Brown) to the research, double click on the picture below. (The announcement the following week that McKree and Brown would be replaced was, we believe, unrelated.)
