Attention Allocation to Projection Level Alleviates Overconfidence in Situation Awareness

Abstract

Overconfidence in situation awareness (SA) can lead to various detrimental consequences, including risky behaviors. This study investigates the influence of stress and attention allocation on SA in manufacturing. Specifically, this study aims to (1) examine the effects of stress on objective SA, (2) explore the relationship between SA levels and SA overconfidence, and (3) investigate the potential alleviation of SA overconfidence through attention allocation to more challenging SA levels. These findings demonstrate that stress impairs the comprehension aspect of SA. Moreover, SA overconfidence increases with the SA level. In exploring strategies to mitigate SA overconfidence, allocating attention specifically to the most challenging SA level—SA projection—proved effective in alleviating overconfidence. These findings contribute to future SA research by clarifying the relationship between stress and SA, uncovering the link between SA levels and SA overconfidence, and exploring methods to alleviate overconfidence and improve decision accuracy in manufacturing systems.
