This previous work has tended to present infants with actors whose behaviors are entirely prosocial or entirely antisocial. Studies introducing even minor variation into an actor's behaviors have yielded null results with infants in the first year of life, suggesting that infants find it difficult to evaluate others who behave even mildly inconsistently. That said, it may be that past studies were poorly designed to test infants' evaluations of inconsistent actors. The present, preregistered experiments further explored 11-month-old infants' (N = 141) ability to evaluate inconsistent actors, using an online testing format and pre-recorded puppet shows depicting helping and hindering interactions. In Experiment 1, infants selectively looked...
