The authors investigated individual differences among super-recognizers and neurotypical controls by systematically varying retinal availability, bandwidth, and orientation of faces' spatial frequency content in two face matching experiments.Abstract:
Facial identity matching ability varies widely, ranging from prosopagnosic individuals (who exhibit profound impairments in face cognition/processing) to so-called super-recognizers (SRs), possessing exceptional capacities. Yet, despite the often consequential nature of face matching decisions-such as identity verification in security critical settings-ability assessments tendentially rely on simple performance metrics on a handful of heterogeneously related subprocesses, or in some cases only a single measured subprocess. Unfortunately, methodologies of this ilk leave contributions of stimulus information to observed variations in ability largely un(der)specified. Moreover, they are inadequate for addressing the qualitative or quantitative nature of differences between SRs' abilities and those of the general population. Here, therefore, we sought to investigate individual differences-among SRs identified using a novel conservative diagnostic framework, and neurotypical controls-by systematically varying retinal availability, bandwidth, and orientation of faces' spatial frequency content in two face matching experiments. Psychophysical evaluations of these parameters' contributions to ability reveal that SRs more consistently exploit the same spatial frequency information, rather than suggesting qualitatively different profiles between control observers and SRs. These findings stress the importance of optimizing procedures for SR identification, for example by including measures quantifying the consistency of individuals' behavior.read more

Accurate but inefficient: Standard face identity matching tests fail to identify prosopagnosia
TL;DR: In this article , the authors examined the capacity of four tests requiring binary face-matching decisions to study individual differences between healthy observers, and used performance of the patient with acquired prosopagnosia (Rossion, 2018) as a benchmark.

Characteristic fixation biases in Super-Recognizers
TL;DR: The authors investigated potential gaze biases in Super-Recognizers (SRs), individuals with exceptional face identity processing skills, and found that SRs showed a stronger gaze bias toward faces and away from text and touched objects, starting from the first fixation onward.

Face-Information Sampling in Super-Recognizers

TL;DR: The authors found that super-recognizers made more fixations, focused less on eye region, and distributed their gaze more than typical viewers, indicating that they are reflective of factors that vary dimensionally in the broader population.

Face Recognition in Police Officers:Who Fits the Bill?
TL;DR: In this paper , the authors benchmark the three most challenging face identity processing (FIP) tests available against two work-samples and find that performance on either work-sample was better predicted by performance on the other than by lab-based test scores.

TL;DR: In this paper , the first-ever investigation of Super-Recognizers' ability to identify perpetrators using authentic case material was conducted. And the results provided external validity for the recently proposed diagnostic framework and its tests used for SR identification.

TL;DR: A technique for image encoding in which local operators of many scales but identical shape serve as the basis functions, which tends to enhance salient image features and is well suited for many image analysis tasks as well as for image compression.
