Abstract: Some types of decision-making can be very complex but may be aided by decision support systems (i.e., automation). However, these support systems are not always reliable and so it is imperative that the user know when to trust them and when not to (calibration). Previous research has shown that providing users with a so-called system confidence value can help improve calibration of user’s trust of automation with actual system reliability on a trial by trial basis. The current study examines how system confidence information presented anthropomorphically affects trust and performance with a decision support system. The first study will examine the attentional demand of each display, while the second study will examine their effect on trust and performance on a decision making task. In addition, the relationship between overall reliability and system confidence will be examined.
