Effects of sex of speaker and sex of dyad partner on selected linguistic variables were examined in four-minute segments of 20 conversations between previously unacquainted college students. Five male dyads, five female dyads, and ten mixed dyads were studied. Three significant interaction effects were found. Males and females produced about the same number of qualifying words ("maybe,""sort of") when talking to males, but males produced fewer and females produced more qualifying words when talking to females. Both males and females produced more false starts when speaking to someone of their own sex than when speaking to someone of the opposite sex. Inequality between dyad members in number of words spoken was greater in female dyads than in male or mixed dyads. (Author)
