Abstract

Conversational partners tend to converge (become more similar) on various speech and discourse characteristics, enhancing social affiliation. We examined convergence in the discourse of eight participants with bilateral ventromedial prefrontal cortex (VMPC) damage and eight healthy comparison participants (NC) each interacting with a clinician. Changes in total words, words/turn, and backchannels were assessed across the interaction by comparing the first ¼ and last ¼ of the session. Preliminary results suggest that convergence was displayed in NC interactions as conversational partners become more similar to one another across variables. In striking contrast, VMPC interactions did not display convergence across any variables.
