Findings from Heinrich-Heine-University Dusseldorf in the Area of Cognitive Psychology Described (Validating a multinomial processing tree model for measuring confidence in lineups using a post-response feedback manipulation).

This article focuses on the validation of the lineup confidence model, an extension of the two-high threshold eyewitness identification model, developed to measure confidence alongside four cognitive processes involved in lineup responses: culprit-presence detection, culprit-absence detection, biased suspect selection, and guessing-based selection. Conducted by researchers at Heinrich-Heine-University Düsseldorf, Germany, the study used a large sample (N = 1565) and post-response feedback to manipulate confidence, finding that confidence levels corresponded predictably with underlying cognitive processes without affecting their measurement. The research suggests the lineup confidence model can effectively examine how lineup features and external factors influence eyewitness confidence. Funded by the Deutsche Forschungsgemeinschaft, the study contributes to cognitive psychology by refining tools for assessing eyewitness identification accuracy. [Extracted from the article]
