Abstract

Our largest multidisciplinary problems outpace disciplinary training designed to reinforce boundaries. Using an interdisciplinary conversation about adolescent brain imaging, I argue that disciplinary stances (interdisciplinary, transdisciplinary) operate like rhetorical stases, helping diagnose where conversations build or diverge among experts. Because what constitutes interdisciplinarity is contested, mapping rhetorical features of each disciplinary stance stabilizes definitional debates by grounding interactions in specific discursive practices and offers technical communicators ways to facilitate and participate in stronger crossdisciplinary communication.
