The goal was to investigate variables related to the sensitivity to unwanted transparency, defined as the feeling that a person experiences during an interaction when the interacting partner seemingly notices something that the person would rather conceal. Undergraduates (n = 309) were asked to complete self-report scales about their self-consciousness, shyness, nonverbal skills, secretiveness, and sensitivity to unwanted transparency. The combination of variables (private self-consciousness, shyness, and secretiveness and lack of nonverbal expressions) explained 23% of the variance in sensitivity to unwanted transparency.
