Notes. Target photos in the Old trials were in fact photos of the actor who performed the action in question, whereas Non-Target photos were of a new actor. Target photos in the Conjunction trials were photos of a familiar actor who had been seen doing something else, whereas Non-Target photos were of a new actor. Target photos in the New Actor items were of an unfamiliar actor, just as were the non-target photos. The three mean proportions in each row add up to 1.0 because they represent the three possible answers to each item.
