Verbal and nonverbal patterns of dominance in dyads formed from a group of 72 college students determined to be sex-type males, sex-type females, or androgynous individuals were investigated in the study described in this paper. The paper first notes problems in recent research on sex differences in communication, presents the research questions guiding the study, and discusses the following topics examined in the study: three aspects of dominance (control, certainty, and superiority/high status behaviors), three aspects of submissiveness (deference, indecision and insecurity, and approval-seeking), and relationships between communication and androgyny. It then describes the procedures, methods of data analysis, and operational definitions of cues used in the study and reports and discusses results related to each of the topics examined. Two general conclusions were drawn from the results: (1) male and female subjects did not conform unilaterally to stereotypic gender-based behaviors with regard to either dominance or submission, and (2) psychological sex and task differences significantly affected patterns of nonverbal behavior on half of the dependent measures. A bibliography, tables of results, and operational definitions of behavioral acts are included. (GW)
