The relationship of task adaptive behavior (TAB) to performance was studied in 31 computer supported groups using a simulated air traffic control task. Each person could access information on specific plane parameters. Based on messages from two specialists, the commanders assigned threat levels to planes that moved in the airspace. Groups worked on two different days. Shifts 1 to 3 (Day 1) and 4 to 6 (Day 2) were compared. Based on a hierarchical task analysis, measures of TAB were developed to assess conformity to specific task requirements beyond general process variables. As hypothesized, TAB predicted performance better than general process variables. The hypothesis that basic task mastery was a better predictor of performance on Day 1 and more sophisticated TAB on Day 2 was supported for two of the three TAB measures. Results underscore the fruitfulness of assessing behaviors specifically adapted to task requirements, and of observations over longer periods of time.

Key Words: development of strategies • group performance • task adaptive behavior
