Eyewitness Accuracy Rates in Sequential and Simultaneous Lineup Presentations: A Meta-Analytic Comparison

Most police lineups use a simultaneous presentation technique in which eyewitnesses view all lineup members at the same time. Lindsay and Wells (R. C. L. Lindsay & G. L. Wells, 1985) devised an alternative procedure, the sequential lineup, in which witnesses view one lineup member at a time and decide whether or not that person is the perpetrator prior to viewing the next lineup member. The present work uses the technique of meta-analysis to compare the accuracy rates of these presentation styles. Twenty-three papers were located (9 published and 14 unpublished), providing 30 tests of the hypothesis and including 4,145 participants. Results showed that identification of perpetrators from target-present lineups occurs at a higher rate from simultaneous than from sequential lineups. However, this difference largely disappears when moderator variables approximating real world conditions are considered. Also, correct rejection rates were significantly higher for sequential than simultaneous lineups and this difference is maintained or increased by greater approximation to real world conditions. Implications of these findings are discussed.     

Eyewitness Accuracy Rates in Police Showup and Lineup Presentations: A Meta-Analytic Comparison

Meta-analysis is used to compare identification accuracy rates in showups and lineups. Eight papers were located, providing 12 tests of the hypothesis and including 3013 participants. Results indicate that showups generate lower choosing rates than lineups. In target present conditions, showups and lineups yield approximately equal hit rates, and in target absent conditions, showups produce a significantly higher level of correct rejections. False identification rates are approximately equal in showups and lineups when lineup foil choices are excluded from analysis. Dangerous false identifications are more numerous for showups when an innocent suspect resembles the perpetrator. Function of lineup foils, assessment strategies for false identifications, and the potential impact of biases in lineup practice are suggested as additional considerations in evaluation of showup versus lineup efficacy.     

The role of behavioral research in the free press/fair trial controversy

The role of behavioral research in the “free press-fair trial” controversy is reexamined in light of the recent article by Carroll, Kerr, Alfini, Weaver, MacCoun, and Feldman (1986). It is concluded that while further research is needed, as suggested by Carroll et al., behavioral research on the impact of pretrial publicity and judicial remedies already offers some useful guidance for the judicial system. In addition, a guideline is proposed for deciding if the empirical literature on a given issue is sufficiently strong to employ in legal decision making.     

Undergraduate Education in Legal Psychology

The purpose of this article is to describe ways that legal psychology can be introduced into the undergraduate curriculum. The extent to which undergraduate psychology and law courses are currently a part of the curriculum is described, and a model is proposed for coursework in a Psychology Department that might adequately reflect coverage of the legal area. The role of legal psychology in interdisciplinary programs and Criminal Justice departments is discussed. Sources for teaching aids and curricular materials are described.

Everyday Life and Legal Values: A Concept Paper

This concept paper emerged from a Law and Human Behavior (LHB) Workshop, that was called by the journal's Editor, Richard Wiener, and held at St. Louis University on March 19–21, 1999. This workshop, which brought together 22 scholars and researchers in legal psychology, was part of James Ogloff's Presidential Initiative Project for the American Psychology/Law Society, and was supported by St. Louis University and an NSF grant. Prior to our arrival, each participant answered queries from the Editor about LHB and the field of psychology and law, and each was asked to offer five topics that were underrepresented in the journal or that we would like to see addressed in future issues. At the workshop, we were assigned to small groups, and the authors of this paper constituted one such group. The charge for all groups was to develop plans for encouraging submissions in areas of psycholegal scholarship that continue to be infrequent topics of investigation, and then to develop a concept paper. The direction our group took is captured by our title, Everyday Life and Legal Values, and within this paper we explicate the topic, identify a number of underrepresented research areas, suggest some research paradigms for investigating them, and present this within a perspectival directions frame that ties established lines of research to the newer ones we propose.
