Work and studies
Most of Dr. Penrod's work has dealt with eyewitness studies. In one of his most commonly cited articles (according to Harzing), “Eyewitness Identification Procedures: Recommendations for Lineups and Photospreads,” he discusses the topic of eyewitness identification and recommends different techniques to help lower the chances of false identification. Examples of these include double-blind lineups, informing witnesses that the suspect may not even be present in the lineup, and choosing distractors carefully based on the witness's verbal description.
Another study, “Meta-analysis of facial identification studies” focuses on discovering what variables influence facial identification performance and what aspects of this topic should be further studied. Some variables that were found to affect performance were context reinstatement, target distinctiveness, elaboration at encoding, exposure time, cross-racial identification, and retention interval. He also did a study, “Choosing, confidence, and accuracy: A meta-analysis of the confidence-accuracy relation in eyewitness identification studies,” which deals with confidence of eyewitnesses. This study sought to discover the strength of correlation between confidence and accuracy for eyewitness identifying a suspect. It found that those who identified the correct suspect tended to have higher confidence levels than those who were incorrect.
