We examined the effects of perceived common ground on actor's and observer's illusion of transparency. We also explored the possibility that differences in the pattern of illusion of transparency depends on internal experiences. Twenty-five male-friends were paired as an actor and as an observer. Participants recalled three or eight examples of joint activity with their partner. Actors indicated three kinds of internal experiences: sixteen personality traits, best solutions for ten personal dilemmas, and preferences for twelve items. Then they inferred whether their partner could correctly guess these internal experiences. Meanwhile, the observers guessed their partner's internal experiences and judged whether these guesses were correct or not. Effects of ease-of-retrieval were not found, but actors showed greater overestimation of the transparency when the perceived common ground was greater. Similarly, observers showed greater overestimation of the correctness of their guess on the partner's personality when the perceived common ground was greater. The role of internal experiences in determining the relation between illusion of transparency and interpersonal relationships is discussed.
