Article
When you hear the word Super-Recognizer, you may think of comic-book-hero-esque agents searching the underground to find people who went missing decades ago. Compared to this fantasy, the reality seems somewhat less exciting. Super-Recognizers (SRs) were initially reported a decade ago as a collateral while developing tests for developmental prosop...

Accurate face identity processing (FIP) is a critical component of security professions, but unfortunately cannot be improved via training. While accuracy is a high priority, it is neither the only, nor most important performance-measure. Passport control officers must process high-throughput information as efficiently as possible – accurately and...
Article
In recent years, the number of face identity matching tests in circulation has grown considerably and these are being increasingly utilized to study individual differences in face cognition. Although many of these tests were designed for testing typical observers, recent studies have begun to utilize general-purpose tests for studying specific, aty...
Article
Full-text available
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 sett...
Preprint
A face’s memorability refers to the unique combination of its intrinsic visual features facilitating its later recognition. Despite considerable variation in face recognition ability amongst the general population, individuals show substantial concordance regarding the memorability of various faces. And, when the viewpoints across which identities...
Article
Neurotypical observers show large and reliable individual differences in gaze behavior along several semantic object dimensions. Individual gaze behavior towards faces has been linked to face identity processing, including that of neurotypical observers. Here, we investigated potential gaze biases in Super-Recognizers (SRs) - individuals with excep...

Full-text available
Recognizing individuals based on their face represents a critical component of police work – from identity checks to image intelligence. This capacity, which is at best trainable to a limited extent, varies from person to person and represents one of the greatest challenges for the human brain. In particular processing of unfamiliar faces is extrem...

Article
Individual differences in human vision are ubiquitous, but poorly understood. Here, we aimed to understand the neural dynamics and representational code underlying outstanding visual processing abilities. We recruited 15 “super-recognizers” (SRs; individuals in the top 2% of face-recognition ability spectrum) and their matched-controls. Participant...
Article
Full-text available
Recent investigations of individual differences in face matching and face memory have demonstrated striking variability in performance within the same sub-process (i.e. face memory), but also between two different sub-processes (i.e. face matching vs. face memory). Such differences between and within individuals between and within laboratory tests...
Presentation
Over the past decade, the domain of face identity processing has seen a surging interest in inter-individual differences, with a focus on individuals with superior skills, so-called Super-Recognizers (SRs; Ramon et al., 2019; Russell et al., 2009). Their study can provide valuable insights into brain-behavior relationships and advance our understan...

Background: Unfamiliar face processing is an ability that varies considerably between individuals. Numerous studies have aimed to identify its underlying determinants using controlled experimental procedures. While such tests can isolate variables that influence face processing, they usually involve somewhat unrealistic situations and optimized fa...

Article
Full-text available
This article provides a response to five excellent commentaries on our article ‘Super‐recognizers: From the lab to the world and back again’. Specifically, the response summarizes commonalities between these commentaries. Based on this consensus, we propose a flexible framework for the assessment of superior face recognition and outline guiding pri...
Article
Over the past years, much interest has been devoted to understanding how individuals differ in their ability to process face identity. Fast periodic visual stimulation (FPVS) is a promising technique to obtain objective and highly sensitive neural correlates of face processing across various populations, from infants to neuropsychological patients....
Article
Eye movements provide a functional signature of how human vision is achieved. Many recent studies have consistently reported robust idiosyncratic visual sampling strategies during face recognition. Whether these inter-individual differences are mirrored by idiosyncratic neural responses remains unknown. To this aim, we first tracked eye movements o...
Article
Manual and saccadic reaction times (SRTs) have been used to determine the minimum time required for different types of visual categorizations. Such studies have demonstrated extremely rapid detection of faces within natural scenes, whereas increasingly complex decisions (i.e. levels of processing) require longer processing times. We reasoned that v...
Preprint
How do humans process unfamiliar faces, and how can we reliably identify individuals that are most proficient at it? Motivated by its relevance in applied contexts, much empirical work has sought to answer these questions. Controlled laboratory tests have been developed to understand the contribution of different variables and inter-individual diff...
Article
Full-text available
The recent discovery of individuals with superior face processing ability has sparked considerable interest amongst cognitive scientists and practitioners alike. These ‘Super-recognizers’ (SRs) offer clues to the underlying processes responsible for high levels of face processing ability. It has been claimed that they can help make societies safer...

Manual and saccadic reaction times (SRTs) have been used to determine the minimum time required for different types of visual categorizations. Such studies have demonstrated that faces can be detected within natural scenes within as little as 100ms (Crouzet, Kirchner & Thorpe, 2010), while increasingly complex decisions require longer processing ti...
Article
Determining the familiarity and identity of a face have been considered as independent processes. Covert face recognition in cases of acquired prosopagnosia, as well as rapid detection of familiarity have been taken to support this view. We tested P.S. a well-described case of acquired prosopagnosia, and two healthy controls (her sister and daughte...
Article
In their review, Geskin and Behrmann address the longstanding question of whether congenital prosopagnosia (CP) is a face-specific or domain-general disorder. The authors review CP cases reported over the past 40 years, categorizing them according to capacities assessed (face, object processing), and measures considered (accuracy, reaction times)....

Full-text available
Acquired prosopagnosia is primarily defined as a defect in recognizing familiar faces. Nonetheless, for practical and methodological reasons, studies of such rare patients typically use pictures of unfamiliar faces. Here, we report an extensive investigation (17 behavioural tasks grouped in nine experiments) with a homogenous set of personally fami...

Independence and objectivity are the chief principles assumed to underlie internal auditors’ fraud-risk judgments. However, a substantial body of evidence regarding attractiveness stereotyping and the attractiveness halo effect suggests that physical attractiveness of potential suspects may influence internal auditors’ fraud-risk judgments accordin...
Article
Understanding how humans form a coherent percept of the visual word represents a major endeavor for cognitive and vision scientists alike. Variations in task demands elicit different neural representations of identical visual input. However, it remains unclear how and where in the brain external and internal inputs interact. To address this fundame...
Article
Recent evidence suggests that the structure conveyed by horizontally-oriented spatial frequency components is maximally diagnostic for face identity, and that selective processing of this structure is correlated with face identification performance (Pachai et al, Front Psychol, 2013). Given that processing of facial information for identification a...
