Reconsidering the Trade-off between Speed and Accuracy: The Role of Perceived Goal Progress Velocity

Abstract

Previous research has found a consistent trade-off between speed and accuracy. Whereas completing work tasks quickly is generally associated with increased mistakes, slowing down allows individuals to work in a more careful and accurate manner. However, this previous work has not considered the implications that subjective speed perceptions have for accuracy. To this end, we draw on control theory accounts of goal progress velocity, which predict that feeling slow is associated with negative emotional experiences. We argue that slow perceived progress is frustrating, and that this frustration can hinder accuracy. We tested our hypotheses using an experiment in which participants (N = 92) completed a work simulation. Importantly, actual speed was held constant across conditions, and instead we manipulated participants’ subjective interpretations of their rate of progress. As expected, feeling slow was associated with increased frustration, which in turn was negatively associated with accuracy. The results of this study imply that, contrary to the typical finding of a trade-off between speed and accuracy, there are situations in which slowing down can actually hinder accuracy. Therefore, the current research adds important nuance to the literature on speed-accuracy trade-offs. Additionally, this research provides the most direct test of control theory predictions regarding velocity to date. We conclude with a discussion of the implications of these results for both theory and practice.
