Our actions are often motivated by the expectation of certain outcomes. We investigated the effect of reward expectancy and its violation during social interactions. The cortical oscillatory correlates of collaborative actions of parents and their children were measured using high-density EEG. Parent-child dyads (mean child age: 4.6 years) played a turn taking game with high and low reward outcomes after every turn. After participants had learned the rules of the game, the reward contingency was randomly reversed in 20%of trials, thereby eliciting prediction errors. Independent component analysis (ICA) was used to determine and exclude non-brain components. Children and parents both exhibited strongP3a andP3bpositivity in response to their ownhigh vs. low reward outcomes. Interestingly, duringparents’observationof their child's action, the P3a was effected by the parent's expectation of high or low reward, but not by the actual outcome. This event-related effect might be an indication of parents’ increased attention to the consequences of their children's actions. The effect of expectancy violation on children's eventrelated potential varies highly between individuals. Finally, preliminary results suggest that parent-child dyads exhibit patterns more closely related to each other than to other participants of the same cohort.
