Biting a pen with your teeth or your lips should induce one of two different "Type I Thinking" facial expressions, associated with Kahneman's "fast thinking" as I understand it. This study appears to discuss the link between forcing a type I physical response, while attempting to prompt a type II response (laughter/humor). As I'm reading it, this study is talking about a previous study in which fuzzing the "fast thinking" system affected the "slow thinking" system. This new paper calls those results into question.
