Participant-witnesses viewed a crime video and attempted to identify the culprit from a culprit-absent lineup. The 253 mistaken-identification eyewitnesses were randomly given confirming, disconfirming, or no feedback regarding their identifications. Feedback was immediate or delayed 48 hr, and measures were immediate or delayed 48 hr. Confirming, but not disconfirming, feedback led to distortions of eyewitnesses' recalled confidence, amount of attention paid during witnessing, goodness of view…

The effect of post-identification feedback, delay, and suspicion on accurate eyewitnesses.

The suspicion manipulation only affected participants' certainty when the confirming feedback created certainty inflation, which lends support to the accessibility interpretation of the post-identification feedback effect and the erasure interpretations of the suspicion effect.

The Effect of Post-Identification Feedback, Delay, and Suspicion on Accurate Eyewitnesses

We examined whether post-identification feedback and suspicion affect accurate eyewitnesses. Participants viewed a video event and then made a lineup decision from a target-present photo lineup.

Memory distortion in eyewitnesses: a meta-analysis of the post-identification feedback effect

Feedback administered to eyewitnesses after they make a line-up identification dramatically distorts a wide range of retrospective judgements (e.g. G. L. Wells & A. L. Bradfield, 1998 Journal of

The effects of post ‐identification feedback and age on retrospective eyewitness memory

Two studies examined the effects of post-identification feedback, age, and retention interval on participants' memories and beliefs about memories for a videotaped event, as captured by a store

The Eyewitness Post Identification Feedback Effect 15 Years Later: Theoretical and Policy Implications

Eyewitnesses' retrospective reports of certainty, view, attention, and other judgments constitute central variables used by courts to assess the credibility of eyewitness identification evidence.

SUMMARY Suggesting to eyewitnesses who mistakenly identify someone from a lineup that they identified the right person leads them to recall having been more certain, having a better view during

When Snitches Corroborate: Effects of Post-identification Feedback from a Potentially Compromised Source

Results show that confirming feedback from a snitch has the same effect as a confession made by the actual suspect, and disconfirming feedback reduces confidence.

Eyewitness confidence malleability: Misinformation as post-identification feedback.

The results highlight the need for lineup administrators to both ask for and document verbatim witness confidence at the time of the initial identification, and suggest both confirming misinformation and typical feedback would significantly inflate witness confidence relative to no feedback controls.

The Mitigating Effects of Suspicion on Post-Identification Feedback and on Retrospective Eyewitness Memory

Three studies examined procedures for reducing the post-identification feedback effect by manipulating suspicion regarding the motives of the lineup administrator, and the effect of confidence prophylactic varied with retention interval such that it eliminated the effects of post-Identification feedback immediately but not after a retention interval.

Is Manipulative Intent Necessary to Mitigate the Eyewitness Post-Identification Feedback Effect?

The results suggest that retrospective judgments of certainty, attention, view, and other testimony-relevant measures remain malleable as new information unfolds.



Effects of postidentification feedback on eyewitness identification and nonidentification confidence.

Two experiments investigated new dimensions of the effect of confirming feedback on eyewitness identification confidence using target-absent and target-present lineups and (previously unused)

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

"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

The damaging effect of confirming feedback on the relation between eyewitness certainty and identification accuracy.

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.

Eyewitness Identification Procedures: Recommendations for Lineups and Photospreads

There is increasing evidence that false eyewitness identification is the primary cause of the conviction of innocent people. In 1996, the American Psychology/Law Society and Division 41 of the

Juror sensitivity to eyewitness identification evidence

A mock-jury study was conducted to examine juror sensitivity to eyewitness identification evidence. Subjects were 129 eligible and experienced jurors from Dane County, Wisconsin, who viewed a

The Tractability of Eyewitness Confidence and Its Implications for Triers of Fact

A theft staged for 80 unsuspecting eyewitnesses was followed by a picture lineup that did or did not contain the thief. In an attempt to see if eyewitness confidence is tractable after the

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.
