More than words: Judgments of politicians and the role of different communication channels

We collected short video clips of speakers and created five types of stimuli: (1) the original videos, (2) the audio tracks only, (3) single pictures only, (4) speech content, and (5) stick-figure animations displaying body motion. Participants rated these stimuli on a brief Big Five personality inventory. We then used ratings of the incomplete information conditions to predict ratings of the original video condition. Impressions in the audio track condition were strong predictors throughout all trait ratings. However, other cues were also non-negligible contributors to an overall impression. People even make sense of parsimonious cues, e.g., an animated stick-figure. Thus, presenters on a public stage are not only judged by what they say but also by how they move.
