Using the Topic Categories

Help Us Program Your Abstract Correctly

  • Each society has its own list of topics; choose a topic from any society listing.
  • Remember which society is programming your abstract as that society will receive and program your topic choice.
  • Each society uses a different programming method; your abstract may go to a program committee or a session chair.
  • Knowing which society is programming your abstract eases follow-up. Indicate your preference for oral or poster presentation.
  • While the programming society makes final decisions about oral and poster presentations, indicating your preference on the submission form is key.
  • All accepted abstracts not selected for oral presentation will be programmed as posters.
  • Submitting to a mini-symposium or featured topic is not an automatic request for oral presentation; you may request a poster presentation for a mini-symposium or featured topic.
  • AAA hybrid symposia and platform sessions (formerly called mini-symposia) are oral presentations. Abstracts not selected will be programmed as posters.
