Infants look longer and explore more following violations-of-expectation, but the reasons for these surprise-induced behaviors are unclear. One possibility is that expectancy violations heighten arousal generally, thereby increasing infants’ post-surprise activity. Another possibility is that infants’ exploration reflects the search for an explanation for the surprising event. We tested these alternatives in three experiments. First in Experiment 1 we confirmed that seeing an object violate expectations (by passing through a solid wall) increased infants’ exploration of the surprising object, relative to when no expectancy violation was seen. Then in Experiment 2 we measured infants’ exploration after they had seen the same violation event, but then an explanation for the event was provided (the wall was revealed to have a large hole in it). We found that providing this explanation abolished infants’ surprise-induced exploration. In Experiment 3 we replicated this effect. Furthermore, we found that the longer infants looked at the explanation, the greater their reversal in exploratory preference (i.e., the more they ignored the surprising object). These findings demonstrate that preverbal infants both seek and recognize explanations for surprising events. •Infants preferentially explore objects that violated their expectations.•We asked whether this surprise-induced exploration reflects explanation-seeking.•Infants showed heightened object exploration following a solidity violation.•This exploration stopped if infants were provided a plausible explanation of the event.•Individual differences in processing the explanation predicted exploratory behavior.
