Familiarity effects in nonverbal understanding: Recognizing our own facial expressions and our friends'

In this study we explored how individuals' private expressions are interpreted by the self, same-sex friends, and strangers. Videotapes were made of participants as they watched pleasant, unpleasant, and unusual slides. Approximately a year later, the tapes were shown to the participant, a same-sex friend, another participant, and the other participant's friend. Judges were able to read the facial expressions at levels of accuracy that were significantly greater than chance. They were no better at reading familiar targets (themselves or their friends) than unfamiliar ones (strangers), with only one exception (men were better at recognizing the reactions of familiar targets than unfamiliar targets viewing pleasant slides). In their abilities to understand nonverbal cues, female friends showed resemblances to each other on all accuracy measures (pleasant/unpleasant/unusual X familiar/unfamiliar). Male friends resembled each other only in their understanding of the reactions of unfamiliar men viewing unpleasant slides.This research was supported in part by an NSF grant and an NIMH Research Scientist Development Award to the second author.
