A common problem in specialized research is to present the background so that the audience will understand the significance of one's research. Oftentimes one cannot discuss the full scope of the research or results and implications. Another problem is that with several panel participants, interaction is sometimes temporally limited in question periods. Usually only a few people are able to ask questions, and the discussant may not cover the concerns of the auditors. The two hour poster session allows for considered dialogue and engaging interaction.
Poster sessions are a consideration to foreign colleagues.
As major associations promote international exchange of ideas and research, the poster allows our foreign colleagues a format to optimally present their research. Many of our Asian, European, African and Latin American colleagues can write in English but may not speak so fluently. We could value more from their research and they would be more comfortable with the poster presentations.
