Interfaces and Time Pressure: Effects on Team Performance

Leonard Adelman, Sheryl Miller, and Cedric Yeo

This is an abstract for the talk I gave recently at the Brunswik Society meeting in Berlin:

Relative Effectiveness of Different Interfaces to Ameliorate the Negative Effects of Time Pressure on Team Performance

An experiment was performed to investigate the relative effectiveness of a perceptually oriented interface, versus one providing cognitive feedback, to ameliorate the effect of increasing time pressure on the performance of hierarchical teams, which were represented conceptually by the multi-level lens model. The perceptually oriented interface was more effective than the one providing cognitive feedback because its visual cues helped teams maintain a high percentage of judgments under increasing time pressure. The cognitive feedback condition did not maintain high judgment accuracy, as had been predicted. Only the time pressure manipulation significantly affected judgment accuracy. A causal model using lens model equation parameters and Multi-Level Theory constructs (e.g., team informity and staff accuracy) showed that the time pressure effect was fully mediated by decreasing team informity. As team informity decreased with increasing time pressure, staff accuracy decreased (due to lower G) and leader accuracy decreased (due to lower G and Rs). These results suggest that time pressure effects on a team's judgment accuracy may be due more to a breakdown in information flow than a breakdown in judgment processing.
