Abstract

Purpose . (1) To investigate the effects of emotional arousal and weapon presence on the completeness and accuracy of police officers' memories; and (2) to better simulate the experience of witnessing a shooting and providing testimony. Methods . A firearms training simulator was used to present 70 experienced police officers with either a shooting or a domestic dispute scenario containing no weapons. Arousal was measured using both self‐report and physiological indices. Recall for event details was tested after a 10‐minute delay using a structured interview. Identification accuracy was assessed with a photographic line‐up. Results . Self‐report measures confirmed that the shooting induced greater arousal than did the other scenario. Overall, officers' memories for the event were less complete, but more accurate, when they had witnessed the shooting. The recall and line‐up data did not support a weapon focus effect. Conclusions . Police officers' recall performance can be affected both qualitatively and quantitatively by witnessing an arousing event such as a shooting.

  • Many studies in the eyewitness field use single session designs, with encoding and retrieval taking place on the same day, mostly within minutes of each other.

    “Many studies in the eyewitness fi eld use single session designs, with encoding and retrieval taking place on the same day -mostly within minutes of each other (e.g., Davis et al., 2019; Hulse & Memon, 2006; Pezdek et al., 2020; Valentine & Mesout, 2009).”

  • Many eyewitness studies implement the stressor at the same time as the to-be-remembered stimulus or event.

    “Thus, to replicate the applied context, much of the research implements the stressor at the same time as the to-be-remembered stimulus or event (e.g., most experiments in De ff enbacher et al., 2004; Hulse & Memon, 2006; Morgan et al., 2004).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
