Abstract
An "illusion of transparency" (Gilovich, Savitsky, & Medvec, 1998) is a tendency for individuals to overestimate the extent to which their internal states are apparent to others. Three experiments were conducted based on the Gilovich et al.'s procedure (1998; Study 2), in which actors were instructed to conceal their disgust from observers while drinking an unpleasant tasting drink. In Study 1a, Japanese actors also showed the illusion (n=45). In the face-to-face condition in Study 1b (n=46), the illusions of transparency did not disappear, indicating that the results of study 1a were not just an experimental artifact. In Study 2 (n=116), intensity of the inner experience of the actor increased the magnitude of actors' illusions. The subjectivity and universal cognitive biases during communication of internal states are discussed.
