Evidence for selective emotional memory enhancement in a mock witness paradigm.

Elucidating the effects of negative emotion on eyewitness memory is an important part of understanding how witnesses remember and report criminal events. Extant research in this area has been inconsistent in its methodology and conclusions, thus warranting further empirical investigation. In the current experiment, participants ( = 204) viewed either a Negative or Neutral version of a video of a staged social interaction and had their memory assessed either immediately or 1 week later. Memory assessment consisted of both recall and recognition (lineup identification) components. The Negative video group showed enhanced recall for some aspects of the video compared to the Neutral group, but no enhancement (or impairment) of lineup identification performance. Theoretical and practical implications are discussed. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Lineup position affects guessing-based selection but not culprit-presence detection in simultaneous and sequential lineups.

The two-high threshold eyewitness identification model was applied to investigate the effects of lineup position on the latent cognitive processes underlying eyewitness responses in lineups. In two experiments with large sample sizes and random assignment of culprits and innocent suspects to all possible lineup positions, we examined how detection-based and non-detection-based processes vary across the positions of six-person photo lineups. Experiment 1 (N = 2586) served to investigate position effects in simultaneous lineups in which all photos were presented in a single row.

Cognitive and social factors can deteriorate eyewitness identification performance in children and older adults. An identification procedure that mitigates the effect of such factors could be beneficial for child and older adult witnesses. In a field experiment, we mapped identification performance in a large community sample (N = 1239) across the lifespan (ages 6-79 years) for two different identification procedures: classic lineups and reaction time-based Concealed Information Test (RT-CIT).

Prior research has investigated ways to optimize identification performance, but an open question concerns exactly what variable should be optimized. One reasonable way to optimize performance is to maximize discriminability, which is achieved by increasing correct identifications of guilty suspects while simultaneously decreasing false identifications of innocent suspects. Another reasonable way to optimize performance is to maximize the information about the guilt or innocence of the suspect, which is best achieved by ensuring that a confidence rating is always made to the suspect.

This research aims to examine both the prosodic-acoustic features and the perceptual correlates of foreign-accented English and foreign-accented Brazilian Portuguese and check how the speakers' productions of foreign and native accents are correlated to the listeners' perception. In the Methodology, we conducted a speech production procedure with a group of American speakers of L2 Brazilian Portuguese and a group of Brazilian speakers of L2 English, and a speech perception procedure in which we performed voice lineups for both languages.For the speech production statistical analysis, we ran Generalized Additive Models to evaluate the effect of the language groups on each class (metric or prosodic-acoustic) of features controlled for the smoothing effect of the covariate(s) of the opposite class.

While research has shown that wearing a disguise hinders lineup identifications, less is known about how to conduct lineups in cases of disguised perpetrators. We examined the influence of surgical masks, worn during a crime event (encoding) and within lineups (retrieval), on eyewitness identification accuracy. In our experiment, 452 participants watched a mock-crime video and identified the perpetrator from either a target-present or a target-absent simultaneous lineup.
