This study examines two aspects of conversational behavior that might
lead to high perceived social influence in newly formed discussion gro
ups, namely, to gain speaking turns by interrupting others and, conver
sely to retain speakership against others' interruptions. Subjects dis
cussed the issue of euthanasia and afterward ranted their own and each
other's influence. Relative to low-ranking members, high-ranking memb
ers were more successful in interrupting others and in gaining speakin
g turns by other, noninterruptive means. When being interrupted high-r
anking members were better able to maintain the floor However the form
er also yielded to interruptions more frequently, probably because of
the larger number of overall interruptions they received. Further anal
ysis showed that certain speech acts (dissent, offer reply) were more
strongly associated than, others (consent, reaction, request) with the
successful enactment of interruptions and that, contrary to stereotyp
ic beliefs, interruptions were not always disruptive but could functio
n constructively in rescuing and promoting group discussion.
