Time Pressure Increases Automation Reliance in a Face Matching Task Open
Automated facial recognition (AFR) systems are commonly used to help verify the identity of individuals, often in a one-to-one face matching task. The AFR system may be a decision aid, such that a human operator must ultimately approve the…
Two out of three ain’t bad: Aggregating multiple identification decisions from the same observer improves unfamiliar face matching performance Open
Deciding whether two images show the same person sounds easy, but the average individual achieves accuracy of 60-90% on many unfamiliar face matching tasks. However, overall task performance can be improved by combining the identification …
A criterion-placement theory of face matching Open
Face matching is an important applied task that requires binary decisions to pairs of face images to determine whether these depict the same person (an identity match) or different people (a mismatch). While these choices are mutually excl…

The radio flare and multi-wavelength afterglow of the short GRB 231117A: energy injection from a violent shell collision Open
We present the early radio detection and multi-wavelength modeling of the short gamma-ray burst (GRB) 231117A at redshift $z=0.257$. The Australia Telescope Compact Array automatically triggered a 9-hour observation of GRB 231117A at 5.5 a…
The impact of forensic delay: facilitating facial composite construction using an early-recall retrieval technique. Open
Memory for facial features deteriorates over time, diminishing one's ability to construct an accurate visual likeness of a face (i.e. a facial composite). In Experiment 1, we investigated how retention interval impacts composite constructi…
A Forensic Facial Examiner and Professional Team Advantage for Masked Face Identification Open
Face masks and coverings are often encountered by facial examiners (‘examiners’) in forensic case work. Examiners are skilled at unconcealed face identifications, but their accuracy for masked face identifications is unknown, yet can be us…
This condition impacts every aspect of my life: A survey to understand the experience of living with developmental prosopagnosia Open
This mixed methods study examined the real-world experiences of living with developmental prosopagnosia (face blindness), a lifelong neurodevelopmental condition that severely affects the ability to recognise faces despite otherwise normal…
A Search for Low-frequency Radio Pulses from Long Gamma-ray Bursts with the Murchison Widefield Array Open
It has been proposed that coherent radio emission could be emitted during or shortly following a gamma-ray burst (GRB). Here we present a low-frequency ($170-200$ MHz) search for radio pulses associated with long-duration GRBs using the Mu…
Automated face recognition assists with low‐prevalence face identity mismatches but can bias users Open
We present three experiments to study the effects of giving information about the decision of an automated face recognition (AFR) system to participants attempting to decide whether two face images show the same person. We make three contr…
The Wisdom of the Crowd Can Unmask Faces Open
Accurately determining whether two images show the same person is a surprisingly difficult task, which becomes even harder if one or both faces are wearing medical face masks. Attempts to improve unfamiliar face matching accuracy have gene…
Benchmarking automation-aided performance in a forensic face matching task Open
Carragher and Hancock (2023) investigated how individuals performed in a one-to-one face matching task when assisted by an Automated Facial Recognition System (AFRS). Across five pre-registered experiments they found evidence of suboptimal…
A new way of classifying developmental prosopagnosia: Balanced Integration Score Open
Despite severe everyday problems recognising faces, some individuals with developmental prosopagnosia (DP) can achieve typical accuracy scores on laboratory face recognition tests. To address this, studies sometimes also examine response t…
Evidence for different visual processing strategy for non-face stimuli in developmental prosopagnosia Open
We assembled a test battery to investigate developmental prosopagnosia (DP), a neurodevelopmental syndrome resulting in severe face recognition difficulties. To screen for general cognitive deficits that could explain poor face test perfor…
Trust in Automation and the Accuracy of Human-Algorithm Teams Performing One-to-One Face Matching Tasks Open
The human face is commonly used for identity verification. While this task was once exclusively performed by humans, technological advancements have seen Automated Facial Recognition Systems (AFRS) integrated into many identification scena…
Accounting for speed-accuracy trade-offs in developmental prosopagnosia Open
Despite severe everyday problems recognising faces, some individuals with developmental prosopagnosia (DP) achieve typical accuracy scores on objective face recognition tests. This has led to calls to also examine response time (RT) since …
Data-driven studies in face identity processing rely on the quality of the tests and data sets Open
There is growing interest in how data-driven approaches can help understand individual differences in face identity processing (FIP). However, researchers employ various FIP tests interchangeably, and it is unclear whether these tests 1) m…
Exploring perceptual similarity and its relation to image-based spaces: an effect of familiarity Open
The lack of controlled stimuli transformations is an obstacle to the study of face identity recognition. Researchers are often limited to verbalizable transformations in the creation of a dataset. An alternative approach to verbalization f…
The impact of weapons and unusual objects on the construction of facial composites Open
The presence of a weapon in the perpetration of a crime can impede an observer’s ability to describe and/or recognise the person responsible. In the current experiment, we explore whether weapons when present at encoding of a target identi…

Building a Transdisciplinary Expert Consensus on the Cognitive Drivers of Performance Under Pressure: An International Multi-panel Delphi Study Open
The ability to perform optimally under pressure is critical across many occupations, including the military, first responders, and competitive sport, and depends on a range of cognitive factors. How common these key performance factors are…
Honey authenticity: the opacity of analytical reports—part 2, forensic evaluative reporting as a potential solution Open
The analytical techniques applied to verify honey authenticity are multifaceted and often result in complex data rich certificates of analysis that are open to interpretation and may be opaque to stakeholders without specialist knowledge. …
Exploring perceived face similarity and its relation to image-based spaces: an effect of familiarity Open
One challenge in exploring the internal representation of faces is the lack of controlled stimuli changes. Researchers are often limited to verbalizable changes in the creation of a dataset. An alternative approach to verbalization for int…
Tracking Face learning: Understanding face familiarity in natural and laboratory settings. Open
Familiar faces are processed differently than unfamiliar faces and the time-course of the shift from unfamiliar to familiar face representation is poorly understood. In two studies we looked at face learning in the wild and in the laborato…
Face memory and source memory abilities correlate in typical perceivers. Open
Face ‘Superrecognisers’ not only recognise faces seen long before, but appear to remember where they met, at least anecdotally. It is not theoretically obvious that good face memory should be associated with good source memory (e.g., for s…
