Under ongoing research objectives of the COMPONENT INTEGRATION Task, the present exploratory study was conducted to determine if the use of team consensus feedback leads to improvement of individual interpreter performance. Fifty-four relatively inexperienced enlisted interpreters (recent USAIS graduates) were subjects in the experiment. Pre-treatment and post-treatment tests were given to evaluate individual performance, and a practice phase was provided in which various types of feedback were introduced. Six experimental proficiency maintenance methods were used--three were based on consensus feedback and two on precise feedback (identifications made by experts); and one (control) simulated normal everyday operations with no feedback. Performance was evaluated in terms of amount of gain in target detection and identification scores. Results were in the expected direction; namely, there was greater overall improvement in performance of individuals working in teams with consensus feedback than in performance of individuals working alone with no feedback. Average gain in proficiency was greater under consensus feedback methods in which interpreters checked teammates' reports after each of three stereo pairs than after interpretation of all three stereo pairs. The precise feedback methods, which require ground truth as basis for feedback, resulted in the greatest average gain in interpreter proficiency. Differences among the experimental methods were attributable to improvement in target identification rather than to improvement in target detection. (Author).
