Experiment 3, participants’ use of base rate information was once again moderated by its consistency, but this effect was itself moderated by the diagnosticity of the base rate information. These studies demonstrate that base rate usage can be an adaptive response to environmental contingencies.

Towards a balanced social psychology

Assessing Clinical Decisions of Medical Students

Bob Galbraith, Tim Siftar, Tony LaDuca and Steve Clyman (National Board of Medical Examiners, Philadelphia, PA) E-mail: RGalbraith@NBME.org

We are investigating the use of Clinical Judgment Analysis (CJA) together with other approaches to assess decision making around diagnosis and management in third year (M3) medical students during their pediatric clerkship. A project with Pediatric Clerkship Directors from 15-20 schools in the US is being implemented with advice from Tom Stewart, Tom Tape and Paul Sorum. The first step will be to agree upon 8-12 clinical tasks and to accumulate 50 or more actual cases for each. Testing is projected to start in July 2003, and will be accomplished online using a web-based application that provides both analysis (accuracy, cue utilization etc.) and either cognitive or outcome feedback. The study design should allow us to evaluate the effectiveness of CJA for formative as well as summative assessment among medical students.

Applying real-time cognitive feedback in a dental diagnosis task

Gordon Gattie and Ann Bisantz University at Buffalo, The State University of New York E-mail: ggattie@acsu.buffalo.edu and bisantz@eng.buffalo.edu

Our research examined the effect of ecological predictability and cognitive feedback component on a diagnosis task. We developed a software program requiring participants to make 50 medical judgments of oral diseases, based on an abbreviated case history, color photograph, and cognitive feedback updated after every trial. Therefore, not all cues were explicitly provided to
