Further Evidence for Infants' Preference for Prosocial Over Antisocial Behaviors

This study extends the findings that young infants prefer prosocial to antisocial others (Hamlin & Wynn, Cognitive Development 2011, 26, 30; Hamlin, Wynn, & Bloom, Nature 2007, 450, 557) to older infants (12-24 and 24-36months) with a novel display. We presented infants with short cartoons in which a character (the Protoganist) engaged in a ball play with two others, one acting prosocially (the Giver), and the other antisocially (the Keeper). Afterward, infants were presented with the Giver and the Keeper characters and encouraged to reach for the one of their choices. We found that infants exhibited robust choice for the Giver. In addition, infants' preference for the Giver persisted despite changes in facial features (dark skin, scrambled face). These findings provide further evidence for infant's preference for prosociality.
