The effects of lineup size on eyewitness decision-making: an eye-tracking study

Project Details

Description

This project will increase knowledge about eyewitness decision-making by using the novel approach of eyetracking to study how eyewitnesses engage with differently-sized lineups, which I have demonstrated influences accuracy. Worldwide, police use lineups to test whether a suspect is guilty, but mistaken identifications are the largest contributor to wrongful convictions. One may to reduce these errors is by determining how many lineup members maximise guilty suspect identifications and minimize innocent suspect identifications. Tracking people’s gaze is an innovative and reliable method of examining the decision-making processes involved in eyewitness identifications. We will be the first to use eye-tracking to study how lineup decisions are affected by lineup size. We will also systematically manipulate the plausibility of fillers to differentiate the effects of lineup size from the effects of lineup quality. Using varied stimuli and large samples will aid us to ensure worldwide guidelines are supported by high-quality research.
