Hypothesized relationship between BOLD response and action familiarity. One way in which the present findings might be integrated with findings from many previous studies on familiarity and AON function is if strong BOLD signal is associated with both highly unfamiliar actions and highly familiar actions, with weaker BOLD signal for “generally familiar” actions. At present, this interpretation is highly speculative and will require thorough testing to validate. However, such a relationship is consistent with a predictive coding account of AON activity (see main text).
