Highlights
- Body movements of politicians giving speeches were turned into stick-figure videos.
- Stimuli were rated on dominance, trustworthiness, and competence.
- Simple nonverbal cues were linked to perceptions of dominance and trustworthiness.
- Male speakers from opposition parties received the highest ratings on dominance.
- Body motion has ecological validity and is a nonverbal cue of social relevance.
People read dominance, trustworthiness, and competence into the faces of politicians but do they also perceive such social qualities in other nonverbal cues? We transferred the body movements of politicians giving a speech onto animated stick figures and presented these stimuli to participants in a rating experiment.
Analyses revealed single-body postures of maximal expansiveness as strong predictors of perceived dominance. Also, stick figures producing expansive movements and many movements throughout the encoded sequences were judged high on dominance and low on trustworthiness.
In a second step, we divided our sample into speakers from the opposition parties and speakers that were part of the government, and male and female speakers. Male speakers from the opposition were rated higher on dominance but lower on trustworthiness than speakers from all other groups.
In conclusion, people use simple cues to make equally simple social categorizations. Moreover, the party status of male politicians seems to become visible in their body motions.
