“…Similarly, in Study 2, we found no obvious differences in the content of super‐recognizer and control descriptions despite differences in the mean accuracy of their descriptions. This extends work by Ritchie et al ( 2022 ) who found no relationship between facial features discussed and the accuracy of dyads on a face‐matching task when both images were in view simultaneously. In the context of face communication specifically, Kramer and Gous ( 2020 ) found that discussion of the eyes, nose, mouth, hair, ears and face shape were not associated with identification accuracy.…”

“…This finding suggests that individuals with strong abilities in matching faces can communicate the basis for their decisions effectively and raises the possibility that they are also better able to describe faces. However, the content of participant discussions leading to this communication benefit is not well understood (Ritchie et al, 2022 ). Additionally, facial forensic examiners are known to outperform standard participant groups in face identification ability, and unlike other high‐performers in face identification (i.e., super‐recognizers), they are required to support face identification decisions with verbal justifications and specialized face vocabulary (White et al, 2015 ).…”

Face descriptions inform real‐world identification decisions, for example when eyewitnesses describe criminal perpetrators. However, it is unclear how effective face descriptions are for identification. Here, we examined the accuracy of face identification from verbal descriptions, and how individual differences in face perception relate to producing and using descriptions for identification. In Study 1, participants completed a face communication task in pairs. Each participant saw a single face, and via verbal communication only, the pair decided if they were viewing the same person or different people. Dyads achieved 72% accuracy, compared to 81% when participants completed the task individually by matching face pairs side‐by‐side. Performance on the face communication and perceptual matching tasks were uncorrelated, perhaps due to low measurement reliability of the face communication task. In subsequent studies, we examined the abilities of face ‘describers’ (Study 2) and ‘identifiers’ separately (Study 3). We found that ‘super‐recognizers’ – people with extremely high perceptual face identification abilities – outperformed controls in both studies. Overall, these results show that people can successfully describe faces for identification. Preliminary evidence suggests that this ability – and the ability use facial descriptions for identification – has some association with perceptual face identification skill.

“…In line with Dowsett and Burton (2015) and Ritchie et al (2022), the data were then split by performance in the pair (high performer, low performer) to test whether the pairs advantage was driven by improvements in the lower performer. Participants were defined as high and low performers based on their accuracy (percentage correct) at T1.…”

“…However, these main effects were qualified by a significant Pair Member × Experimental Session interaction, F (2, 184) = 11.19, p < .001, η p 2 = .11, BF 10 > 100. In order to break down the interaction and test our hypothesis that, as in Ritchie et al (2022), pairs training would predominantly affect the performance of the low performer in each pair, follow up one‐way ANOVAs were conducted for the high and low performers separately.…”

It is becoming increasingly common for face morphs (weighted combinations of two people's photographs) to be submitted for inclusion in an official document, such as a passport. These images may sufficiently resemble both individuals that they can be used by either person in a ‘fraudulently obtained genuine’ document. Problematically, people are poor at detecting face morphs and there is limited evidence that this can be improved. Here, we tested whether the ‘pairs training effect’ (working in pairs, which we know improves unfamiliar face matching) can improve face morph detection. We found morph detection was more accurate when working in a pair. Further, the lower performer in the pair maintained this benefit when completing the task again individually. We conclude that the pairs training effect translates to face morph detection, and these findings have important implications for improving the detection of face morphs at the initial application stage.

Identification often involves determining whether two face photographs or voice samples originated from the same person. Here, we investigated the wisdom of the (outer) crowd (averaging two individuals' responses to the same trial) and inner crowd (averaging the same individual's responses to the same trial after completing the test twice) as routes to increased performance. Participants completed the same face (Experiment 1) or voice matching test (Experiment 2) twice with no delay. In addition, we reanalysed previously collected data where these tests were completed with a one‐week interval between sessions. For both tests, whether with or without a delay, inner crowds outperformed participants' individual test responses and were equivalent to outer crowds of two participants. Taken together, we demonstrate the use of inner crowds as a robust method of improvement during identification. In contexts where outer crowds are not feasible, agencies should consider inner crowds as a promising alternative.
