Abstract

Confirmation bias is the tendency to selectively attend to information that is consistent with held beliefs. An effective strategy to reduce confirmation bias is the ‘consider-the-opposite’-strategy (COS). The central question of this pre-registered study is whether adding feedback to an instructional COS-video can enhance performance on practice and transfer tasks. It was hypothesized that elaborative feedback in the form of worked examples would be more effective than correct-answer feedback. Participants were 132 university students, who received either elaborative feedback (WE) or correct answer feedback (CA) on practice tasks, practice only (PO), instruction only (VO) or no treatment (NT). Results revealed no difference between both feedback conditions, but a significant difference was found on learning between groups with and without feedback.
