To slow the spread of COVID-19, many people now wear face masks in public. Face masks impair our ability to identify faces, which can cause problems for professional staff who identify offenders or members of the public. Here, we investigate whether performance on a masked face matching task can be improved by training participants to compare diagn...

Finding an unfamiliar person in a crowd of others is an integral task for police officers, CCTV-operators, and security staff who may be looking for a suspect or missing person; however, research suggests that it is difficult and accuracy in such tasks is low. In two real-world visual-search experiments, we examined whether being provided with four...

Convolutional neural networks (CNNs) give the state-of-the-art performance in many pattern recognition problems but can be fooled by carefully crafted patterns of noise. We report that CNN face recognition systems also make surprising ‘errors'. We tested six commercial face recognition CNNs and found that they outperform typical human participants...

The role of image colour in face identification has received little attention in research despite the importance of identifying people from photographs in identity documents (IDs). Here, in two experiments, we investigated whether colour congruency of two photographs shown side by side affects face matching accuracy. Participants were presented wit...
Preprint
The role of image colour in face identification has received little attention in research despite the importance of identifying people from photographs in identity documents (IDs) that are either in greyscale or in colour. Here, we investigated whether comparing a grayscale photograph to a colour image affects face matching accuracy. Participants w...
Article
A reliable self-report measure to assess the broad spectrum of face recognition ability (FRA) from developmental prosopagnosia (DP) to super-recognition would make a valuable contribution to initial screening of large populations. We examined the performance of 96 naive participants and seven super-recognisers (SRs) using a range of face and object...

Full-text available
Non-verbal behaviours, including voice characteristics during speech, are an important way to communicate social status. Research suggests that individuals can obtain high social status through dominance (using force and intimidation) or through prestige (by being knowledgeable and skilful). However, little is known regarding differences in the voc...
Data
Ratings of targets’ attributes given by the participants. Results are split by target (neutral: white bars; dominant: light grey bars; prestigious: dark grey bars) and attribute rated. a) Facial images; b) Employee testimonials; c) Names; d) Job titles. Bars represent mean ± 1 s.e.m. (TIF)
Data
Descriptive statistics for all vocal parameters. Results represent mean ± SD for male and female participants to each type of target (neutral, dominant, prestigious). (XLSX)
Data
Context-dependent variation in vocal parameters. T = Target (neutral, dominant, prestigious), Q = Question, PD = Participant Dominance, PP = Participant Prestige, PS = Participant Sex (male, female). Results are from repeated-measures general linear models for each vocal parameter, with Holm–Bonferroni adjustment for multiple tests. Significant eff...
Data
Planned contrasts estimated for participants with varying degrees of dominance and prestige. T = Target (neutral, dominant, prestigious), Q = Question, PS = Participant Sex, N = Neutral Target, HS = High-status Targets (dominant, prestigious), D = Dominant Target, P = Prestigious Target. For participants, self-perceived status covariates (PD = Part...
Data
Planned contrasts estimated for participants with varying degrees of dominance and prestige, per question. T = Target (neutral, dominant, prestigious), N = Neutral Target, HS = High-status Targets (dominant, prestigious), D = Dominant Target, P = Prestigious Target. For participants, self-perceived status covariates (PD = Participant Dominance, PP...
Data
Independent ratings of target attributes. Mean ratings for each attribute (images, employee testimonials, names, and job titles). N = Neutral target, D = Dominant target, P = Prestigious target. Results are from repeated-measures general linear models (d.f. = 2, 42 in each case) for each rated attribute. Significant effects are in bold. (XLSX)
Data
Excel file with data on participants and analysed acoustic characteristics. (XLSX)

Women wearing cosmetics have been associated with a higher earning potential and higher status jobs. However, recent literature suggests that status can be accrued through two distinct routes: dominance and prestige. In two experiments, we applied a standardized amount of cosmetics to female faces using computer software. We then asked participants...
Article
In recent research, facial width-to-height ratio (fWHR) has garnered considerable attention because it has been linked with different behavioural characteristics (e.g., achievement drive, deception, aggression). Here we examined whether other-perceptions and self-perceptions of dominance are related to fWHR. In study 1, we found that other-perceive...

Evolutionary psychology is a hybrid field that is informed by diverse disciplines. In spite of the integration of an evolutionary psychology perspective into varied fields including, but not limited to, biology, psychology, anthropology, sociology, economics, and primatology, the assimilation of evolutionary paradigms into the realms of feminist re...

Background Many people with mental illness experience stigma that has impacted their lives. In this study, we validated the Inventory of Stigmatizing Experiences (ISE) as a tool to help quantify the stigma experienced by patients with bipolar disorder and its impact on their lives. The ISE has two components, ie, the Stigma Experiences Scale (SES)...
Article
Elevated stress experienced by a mother can compromise both her own reproductive success and that of her offspring. In this study, we investigated whether chronically stressed mothers experienced such effects in cooperatively breeding species, in which helpers at the nest potentially compound the negative effects of maternal stress. Using Neolampro...

In group-living species, dominant individuals are frequently aggressive toward subordinates, and such dominant aggression can lead to chronic stress, higher glucocorticoid levels, and decreased fitness for subordinates. However, in many cooperatively breeding species, it is surprisingly the dominants rather than the subordinates that exhibit higher...
Article
Dementia in the elderly is a common, debilitating condition. Residents in long-term care facilities present with a number of challenging behaviors. Pharmacological management is not always helpful. Alternative approaches are needed. Multisensory stimulation (MSS) was developed to address sensory stimulation imbalance. In this pilot 24-week single-b...
Article
In this thesis I examined behavioural, physiological, and molecular aspects of the stress response of the highly social cichlid Neolamprologus pulcher. Through this work, I established that dominant individuals within a group have higher baseline stress levels (as measured by plasma circulating cortisol concentrations) than subordinate group member...

We are developing face manipulation process, that will potentially allow us to experimentally identify how cortical face processing is affected by relevant signals such as attractiveness, sex, and dominance.
