A pair of psychologists are interested in the effects of mood in helping (based on Isen & Levin, 1972). They give participants free tickets to a happy movie. They then have a confederate drop papers in front of the people who just got out of the movie, and people who are only walking by and have not just seen a happy movie for free. The researchers watch to see if the participants help pick up the dropped papers. Reference: Isen, A. M., & Levin, P. F. (1972). Effect of feeling good on helping: Cookies and kindness. Journal of Personality and Social Psychology, 21(3), 384–388.
