We examined how the assumption of common ground affects actor’s- and observer’s illusion of transparency. One-hundred-and-twenty-eight unacquainted undergraduates made up same-gender actor-observer pairs. Thirty-two pairs exchanged some information to each other, while the other 32 pairs did not. After that, actors indicated their preferences for twelve items: four of them were familiar to male, the other four were familiar to female, and the rest were familiar to both. Then actors inferred whether their partner (observer) could correctly guess their preferences. Meanwhile, observers guessed their partner’s (actor’s) preferences for the 12 items and judged whether their own guess was correct or not. Results showed that familiarity of items affected the magnitude of two types of illusion of transparency. Specifically, illusion of transparency was found on the items that is familiar to the pair’s gender, but was not found on the items that were not familiar to the pair’s gender. Effects of information exchange were not found. Results were discussed in terms of how does the assumption of common ground affects interpersonal communication.
