Accuracy of nonverbal communication as determinant of interpersonal expectancy effects

Abstract

The person perception paradigm was used to address the effects of experimenters' ability to encode nonverbal cues and subjects' ability to decode nonverbal cues on magnitude of expectancy effects. Greater expectancy effects were obtained when experimenters were better encoders and subjects were better decoders of nonverbal cues and the separate contributions of experimenter's and subject's nonverbal skills were of similar magnitudes.
