A collaborative theory of narrative story-telling was tested in two experim
ents that examined what listeners do and their effect on the narrator. In 6
3 unacquainted dyads (81 women and 45 men), a narrator told his or her own
close-call story. The listeners made 2 different kinds of listener response
s: Generic responses included nodding and vocalizations such as "mhm." Spec
ific responses, such as wincing or exclaiming, were tightly connected to (a
nd served to illustrate) what the narrator was saying at the moment. In exp
erimental conditions that distracted listeners from the narrative content,
listeners made fewer responses, especially specific ones, and the narrators
also told their stories significantly less well, particularly at what shou
ld have been the dramatic ending. Thus, listeners were co-narrators both th
rough their own specific responses, which helped illustrate the story, and
in their apparent effect on the narrator's performance. The results demonst
rate the importance of moment-by-moment collaboration in face-to-face dialo
gue.
