Three experiments correlated judgments made from observing single channels (face, body, or speech) with multiple channel judgments (face, body, and speech together; or face and speech together). Judges observed the spontaneous behavior of videotaped student nurses in 2 types of interview situations, "deceptive" and "honest," and rated the nurses on 14 bipolar adjective scales (e.g., awkward–natural). The single channel judgments that correlated most highly with the multiple channel judgments depended on the type of attribute being judged and the situation in which the behavior occurred (e.g., in the deception condition, judgments made from speech had the highest correlation with whole-person judgments).
