Sometimes performing a self-report measure can cause an individual to either intentionally or unintentionally change their performance on a task, this is referred to as reactivity. Positive reactivity occurs when a self-report measure facilitates performance, whereas negative reactivity occurs when a self-report measure has a detrimental effect on performance.
My research has looked at whether confidence ratings are reactive and whether individual differences factors moderate reactivity. So far, we have found that performing confidence ratings facilitates performance in high self-confidence participants, but impairs performance in low self-confidence participants.
We’re now looking at the effect of confidence ratings on performance monitoring and the role of goal orientations.
