Poster sessions at the 89th Meeting of the Acoustical Society of America.

Behavioral observations of communication interaction patterns were gathered for traditional and ''poster paper'' presentations at the 89th Meeting of the Society (7-11 April 1975, Austin, Texas). Affective reactions of poster paper authors and audience members were also surveyed. The overall response to poster sessions was very positive, suggesting continuation of the new mode of technical communication. Poster paper authors were somewhat more positive in their responses than other participants. Although poster sessions produced much more verbal interaction, patterns of interaction did not appear to differ from those observed in traditional presentations. Several problems particular to poster sessions were identified and suggestions for improvement are offered. Subject Classification: [43]05.50; [43]10.85. [ABSTRACT FROM AUTHOR]
