Steven D. Penrod joined the John Jay faculty as Distinguished Professor of Psychology in 2001. He earned his J.D. from Harvard Law School in 1974 and his Ph.D. in psychology from Harvard University in 1979. He was previously on the faculties of the University of Wisconsin-Madison, the University of Minnesota Law School and the University of Nebraska-Lincoln. He has over 130 publications; is a co-author of books on juries, on eyewitnesses, introductory psychology and social psychology; and a co-editor of volumes on research methods in forensic psychology and comparative psychology and law. Professor Penrod's research and writing have focused on decision-making in legal contexts. He has written about the effects of jury size and decision rules on jury decision-making, death penalty decision-making, juror's use of probabilistic and hearsay evidence, comprehension of legal instructions, and the impact of extra-legal influences such as pretrial publicity, joinder of charges, the effects of cameras in the courtroom, the and the effects of juror questioning of witnesses on jury performance. His research and writing about eyewitness evidence has encompassed factors that reduce eyewitness reliability, interview and lineup procedures that may enhance eyewitness performance, child witnesses, jury assessments of eyewitness evidence, the relationship between eyewitness confidence and eyewitness accuracy and the effects of eyewitness expert testimony on jury decision-making.
