Chewing and swallowing research. (Bellisle, France, B. Guy-Grand, and J. Le Magnen (2000). ‘Chewing and Swallowing as Indices of the Stimulation to Eat During Meals in Humans: Effects Revealed by the Edogram Method and Video Recordings.’ Neuroscience and Biobehavioral Reviews 24 (2): 223–28. /  Bellisle, France, and Anne-Marie Dalix (2001). ‘Cognitive Restraint Can Be Offset by Distraction, Leading to Increased Meal Intake in Women.’ American Journal of Clinical Nutrition 74 (2): 197–200. Featuring dramatic readings by Jean Berko Gleason.) Here’s detail from the “Chewing and swallowing” study:

The Improbable Research podcast is all about research that makes people LAUGH, then THINK — real research, about anything and everything, from everywhere —research that may be good or bad, important or trivial, valuable or worthless. CBS distributes it, on the CBS Play.it web site, and on iTunes and Spotify).
