Effects of Stress on Judgment and Decision Making in Dynamic Tasks
Abstract
Three empirical studies on judgment and decision making in dynamic tasks were carried out during the period 1 September 1988 to 31 December 1989. Subjects were expert research meteorologists. Topics were forecasting (a) hail, (b) microbursts, and (c) convection initiation (thunderstorms) at an airport approach. Primary findings were as follows: in the hail study, meteorologists' forecasts were closely approximated by a weighted-sum model; in the microburst study, experts who worked together for years, when tested in work conditions, did not agree on the judgments of principal cues; in the convection study, more accurate forecasts were made on high stress than low stress days, thus contradicting the conventional wisdom. Two annotated bibliographies were produced: the effects of stress on judgment and decision making, and the effects of variation of display formats on judgment and decision making.
