The Effect of Simulation Style on Performance

Abstract

Despite the fact that luggage screening occurs with the dynamic presentation of images, most luggage screening research is conducted with static images. Although some research has suggested that performance with static and dynamic images is equivalent, this has not been addressed in the context of complex visual search tasks such as luggage screening. Participants completed a luggage screening task under either static or dynamic conditions to test the hypothesis that performance would vary by condition. A series of 2 (block) x 3 (condition) mixed ANOVAs revealed that sensitivity was higher in the scrolling condition than in the 3 second condition and that this effect may have been due to presentation time. Results also revealed that performance workload was lower in the 9 second condition than in the scrolling or 3 second condition. Luggage screening simulation styles may be an important consideration when designing research to test the effectiveness of different performance enhancement devices or the impact of different conditions.
