(2009): Effects of Training with Knowledge of Results on Diagnosticity in Vigilance Performance. In: Proceedings of the Human Factors and Ergonomics Society 53rd Annual Meeting 2009. pp. 1066-1070.

Making accurate diagnostic decisions about signal presence/absence is critical for success in many failure intolerant monitoring technologies requiring sustained attention or vigilance. This study examined the effects of training with knowledge of results (KR) on observer diagnosticity in a vigilance task. Diagnosticty was measured in terms of decision theory measures of positive predictive power (PPP) -- precision in indicating when signals were actually present and negative predictive power (NPP) -- precision when indicating signal absence. Initial training with KR enhanced observers' diagnosticity on a subsequent test task in terms of PPP but not NPP. The picture of performance efficiency reflected by both diagnostic measures differed from results indexed by signal detection theory (SDT) measures of perceptual sensitivity (d') and response bias (c). However as predicted from the computational mechanics of the decision theory and SDT measures, both diagnostic measures correlated positively with d' while NPP correlated negatively with c. These findings indicate that combinations of perceptual ability and level of responding can influence the behavioral metrics signifying diagnosticity in vigilance performance.
