"Good, you identified the suspect": Feedback to eyewitnesses distorts their reports of the witnessing experience.
People viewed a security video and tried to identify the gunman from a photospread. The actual gunman was not in the photospread and all eyewitnesses made false identifications (n = 352). Following…
Distortions in Eyewitnesses' Recollections: Can the Postidentification-Feedback Effect Be Moderated?
Giving eyewitnesses confirming feedback after they make a lineup identification (e.g., “Good. You identified the actual suspect.”) inflates not only their recollections of how confident they were at…

The authors hypothesized that extemal influence from the lineup administrator would damage the certainty-accuracy relation by inflating the retrospective certainty of inaccurate eyewitnesses more than that of accurate eyewitnesses.
Race and Information Processing in Criminal Trials: Does the Defendant’s Race Affect How the Facts Are Evaluated?
The results suggest that a Black defendant can elicit greater sensitivity to legally relevant information than will a White defendant.
The Perceived Validity of Eyewitness Identification Testimony: A Test of the Five Biggers Criteria
It is postulated that certainty plays a qualitatively different role from the four other Biggers criteria in evaluations of eyewitness identification testimony, and hypothesized that participants would ignore reports on other criteria when certainty was high (the certainty-trumps hypothesis), but not when surety was low.
Measuring the goodness of lineups: parameter estimation, question effects, and limits to the mock witness paradigm
Lineups and photospreads can be biased against a criminal suspect and there is a need to measure this bias. The mock witness method has been accepted by eyewitness scientists since the 1970s as the…
When Does Evidence of Eyewitness Confidence Inflation Affect Judgments in a Criminal Trial?
Two studies investigated perceptions of eyewitness confidence inflation: increases in a witness's confidence between the time of the identification and the trial. Experiment 1 ( N = 90) demonstrated…
Not the same old hindsight bias: Outcome information distorts a broad range of retrospective judgments
Experiment 2 showed that the effects of hindsight bias were diminished when participants engaged in private thought about the upcoming questions prior to receiving outcome information, suggesting that the effect is not due to impression management concerns.
Witnesses to Crime
A criminal trial involves people who take the stand and recount events that they witnessed firsthand. The purpose of their testimony is to aid the triers of fact in making determinations about a…
