We proposed a new mood induction technique using pictures of smiling baby faces and presented example of application on the technique in choice experiment. Based on Baby Schema (Kindchenschema: Lorenz, K. 1965), we hypothesized that a baby face which consist of a big head, relatively large eyes, and the rounded shape elicits altruistic emotion and positive affect. We conducted a choice experiment using the proposed technique. Subjects were presented slides of smiling baby faces before the choice task. The result of the experiment showed that the baby faces elicited positive mood and then promoted the uses of simple heuristics. This finding suggested efficiency of the proposed technique as a mood induction method.
