Cited Sources
- White paper on lineup procedures (2020) — Mentioned as an influential expert consensus on lineup procedures.
- Colloff et al. (2016) paper on distinctive features — Data from this paper was presented on lineup fairness.
Concurring Sources
- Wells et al. (2020) white paper — Supports the use of fair lineups and description-matched fillers.
Contribution & Novelties
The talk contributes to the field by advocating for theory-driven research in eyewitness identification, specifically using signal detection theory and the feature matching model to make predictions about lineup procedures. It provides empirical evidence that unfair lineups impair discriminability and that lower similarity fillers can improve it.
