Since much of the recent literature concerning leadership has emphasized the study of verbal interactions among leaders and other group members (ignoring the role of nonverbal communication), a study was undertaken to investigate several aspects of nonverbal communication in leadership. Specifically, it examined whether (1) leadership messages were carried by both the verbal and the nonverbal communication channels, (2) observers of only one channel received all the leadership information available through both channels, and (3) observers of a single channel were able to express as much confidence in their leadership perceptions as were observers of both channels. Observers, 145 college students, were presented with videotapes of actual group interactions in one of three experimental conditions: picture only (nonverbal), sound only (verbal), or a combination of picture and sound. Following the viewing of the videotape, the subjects completed rating scales for each group member's task, maintenance, and overall leadership performance. The subjects also indicated their confidence in rating each group member. Results showed that both verbal and nonverbal information were important in evaluating task and maintenance leadership. When either type of information was missing, subjects' judgments of perceived leadership dropped, as did their confidence in the leadership ratings. (FL)
