Police practice of double-blind sequential lineups prompts a question about the efficacy of repeated viewings (laps) of the sequential lineup. Two laboratory experiments confirmed the presence of a sequential lap effect: an increase in witness lineup picks from first to second lap, when the culprit was a stranger. The second lap produced more errors than correct identifications. In Experiment 2, lineup diagnosticity was significantly higher for sequential lineup procedures that employed a… Expand

Running head: WARNINGS REDUCE SEQUENTIAL LAP EFFECT 1 Warnings Reduce the Sequential Lap Effect in Eyewitness Identification
Recent studies in eyewitness identification have pointed to an advantage in accuracy for witnesses to identify suspects from a sequential, rather than simultaneous, lineup. Under the sequentialExpand
Double Exposure: The Effects of Repeated Identification Lineups on Eyewitness Accuracy
Summary Eyewitnesses may be asked to identify the same suspect from a lineup on successive occasions. This study explored the effects on eyewitness decisions of repeated same-suspect lineups, withinExpand
The effects of allowing a second sequential lineup lap on choosing and probative value
When presented with a sequential lineup, witnesses see each member of the lineup individually, essentially making a yes/no decision for each person shown. An important policy question is whetherExpand
Predictors of eyewitness identification decisions from video lineups in England: a field study.
TLDR
Repeated viewing was strongly associated with increased filler identification rates, suggesting that witnesses who requested additional viewings were more willing to guess. Expand
Backloading in the sequential lineup prevents within-lineup criterion shifts that undermine eyewitness identification performance.
TLDR
The results suggest that backloading encourages participants to adopt a more conservative response criterion, and it reduces or eliminates the tendency for the criterion to become more lenient over the course of the lineup. Expand
The effects of sequential and simultaneous lineup procedures on confidence and accuracy of identity judgements
This thesis investigated eyewitness confidence and accuracy in simultaneous and sequential lineups. Simultaneous lineups were found to be superior to sequential lineups and eyewitness confidence wasExpand
Sequential lineup presentation promotes less-biased criterion setting but does not improve discriminability.
TLDR
Sequential (cf. simultaneous) presentation did not influence discriminability, but produced a conservative shift in response bias that resulted in less-biased choosing for sequential than simultaneous lineups, which inform understanding of the effects of lineup presentation mode on eyewitness identification decisions. Expand
Blind sequential lineup administration reduces both false identifications and confidence in those false identifications.
TLDR
Stronger support is provided for the use of blind lineup administration by broadening the conditions under which nonblind administration is shown to inflate false identifications, as well as its effects on witness confidence. Expand
The distance threshold of reliable eyewitness identification.
TLDR
It is concluded that age and line-up type moderate the effect distance has on eyewitness accuracy and that there are perceptual distance thresholds at which an eyewitness can no longer reliably encode and later identify a culprit. Expand

When administering sequential lineups, researchers often inform their participants that only their first yes response will count. This instruction differs from the original sequential lineup protocolExpand

TLDR
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. Expand

TLDR
A new module for PCE, the New Jersey module, was developed to examine the effects of a second pass in lineup administration procedure, and found that the sequential advantage was eliminated when the participants were allowed to view the lineup a second time. Expand
Robustness of the sequential lineup advantage.
TLDR
Unless lineups with particular characteristics predominate in the real world, there appears to be no strong preference for conducting lineups in either a sequential or a simultaneous manner. Expand
Regularities in Eyewitness Identification
TLDR
A meta-analysis of 94 comparisons between target-present and target-absent lineups showed that correct identifications and correct-nonidentifications were uncorrelated, and suspect identifications were more diagnostic with respect to the suspect’s guilt or innocence than any other response. Expand
