ABSTRACT: A show-up is an identification procedure that only presents the witness with one suspect in contrast to a lineup where the suspect is presented among a number of fillers (i.e., known innocent people). This feature makes the show-up procedure very suggestive. In this literature review, an overview of the current research about this identification procedure is presented. The different factors that influence the accuracy in show-up procedures are separated into system (e.g., clothing bias, instruction bias, and the impact of multiple show-ups) and estimator variables (e.g., age, cross-race effects, and alcohol) in line with Wells [1]. The implications of the research are discussed together with suggestions for future research.
