Abstract : The U.S. Army Research Institute for the Behavioral and Social Sciences (ARI) held a formal In-House Researcher Colloquium on 20 November 1997 in Alexandria, Virginia. The main purpose of the colloquium was to provide an opportunity for cross-unit discussion among ARI's more junior researchers. The eight researchers who presented research findings at the colloquium represented ARI's Armored Forces Research Unit, the Automated Training Methods Research Unit, the Fort Leavenworth Research Unit, the infantry Forces Research Unit, the Organization and Personnel Resources Research Unit, the Rotary-Wing Aviation Research Unit, the Selection and Assignment Research Unit, and the Simulator Systems Research Unit. Each research topic was specifically selected by the Research Unit Chief as an example of the best of research being performed at the unit. This report provides brief summaries of the research and biographies of the researchers. It also serves as an example of the range of behavioral and social science research being addressed by in-house researchers at ARI as well as of the backgrounds of ARI's research staff.
