Face masks are less effective than sunglasses in masking face identity.

The effect of covering faces on face identification is recently garnering interest amid the COVID-19 pandemic. Here, we investigated how face identification performance was affected by two types of face disguise: sunglasses and face masks. Observers studied a series of faces; then judged whether a series of test faces, comprising studied and novel faces, had been studied before or not. Face stimuli were presented either without coverings (full faces), wearing sunglasses covering the upper region (eyes, eyebrows), or wearing surgical masks covering the lower region (nose, mouth, chin). We found that sunglasses led to larger reductions in sensitivity (d') to face identity than face masks did, while both disguises increased the tendency to report faces as studied before, a bias that was absent for full faces. In addition, faces disguised during either study or test only (i.e. study disguised faces, test with full faces; and vice versa) led to further reductions in sensitivity from both studying and testing with disguised faces, suggesting that congruence between study and test is crucial for memory retrieval. These findings implied that the upper region of the face, including the eye-region features, is more diagnostic for holistic face-identity processing than the lower face region.

A hidden pandemic? An umbrella review of global evidence on mental health in the time of COVID-19.

Background: The mental health impacts of the COVID-19 pandemic remain a public health concern. High quality synthesis of extensive global literature is needed to quantify this impact and identify factors associated with adverse outcomes. Methods: We conducted a rigorous umbrella review with meta-review and present (a) pooled prevalence of probable depression, anxiety, stress, psychological distress, and post-traumatic stress, (b) standardised mean difference in probable depression and anxiety pre-versus-during the pandemic period, and (c) comprehensive narrative synthesis of factors associated with poorer outcomes. Databases searched included Scopus, Embase, PsycINFO, and MEDLINE dated to March 2022. Eligibility criteria included systematic reviews and/or meta-analyses, published post-November 2019, reporting data in English on mental health outcomes during the COVID-19 pandemic. Findings: Three hundred and thirty-eight systematic reviews were included, 158 of which incorporated meta-analyses. Meta-review prevalence of anxiety symptoms ranged from 24.4% (95%CI: 18-31%, I 2: 99.98%) for general populations to 41.1% (95%CI: 23-61%, I 2: 99.65%) in vulnerable populations. Prevalence of depressive symptoms ranged from 22.9% (95%CI: 17-30%, I 2: 99.99%) for general populations to 32.5% (95%CI: 17-52%, I 2: 99.35) in vulnerable populations. Prevalence of stress, psychological distress and PTSD/PTSS symptoms were 39.1% (95%CI: 34-44%; I 2: 99.91%), 44.2% (95%CI: 32-58%; I 2: 99.95%), and 18.8% (95%CI: 15-23%; I 2: 99.87%), respectively. Meta-review comparing pre-COVID-19 to during COVID-19 prevalence of probable depression and probable anxiety revealed standard mean differences of 0.20 (95%CI = 0.07-0.33) and 0.29 (95%CI = 0.12-0.45), respectively. Conclusion: This is the first meta-review to synthesise the longitudinal mental health impacts of the pandemic. Findings show that probable depression and anxiety were significantly higher than pre-COVID-19, and provide some evidence that that adolescents, pregnant and postpartum people, and those hospitalised with COVID-19 experienced heightened adverse mental health. Policymakers can modify future pandemic responses accordingly to mitigate the impact of such measures on public mental health.

Incongruence in Lighting Impairs Face Identification.

The effect of uniform lighting on face identity processing is little understood, despite its potential influence on our ability to recognize faces. Here, we investigated how changes in uniform lighting level affected face identification performance during face memory tests. Observers were tasked with learning a series of faces, followed by a memory test where observers judged whether the faces presented were studied before or novel. Face stimuli were presented under uniform bright or dim illuminations, and lighting across the face learning and the memory test sessions could be the same ("congruent") or different ("incongruent"). This led to four experimental conditions: (1) Bright/Dim (learning bright faces, testing on dim faces); (2) Bright/Bright; (3) Dim/Bright; and (4) Dim/Dim. Our results revealed that incongruent lighting levels across sessions (Bright/Dim and Dim/Bright) significantly reduced sensitivity (d') to faces and introduced conservative biases compared to congruent lighting levels (Bright/Bright and Dim/Dim). No significant differences in performance were detected between the congruent lighting conditions (Bright/Bright vs. Dim/Dim) and between the incongruent lighting conditions (Bright/Dim vs. Dim/Bright). Thus, incongruent lighting deteriorated performance in face identification. These findings implied that the level of uniform lighting should be considered in an illumination-specific face representation and potential applications such as eyewitness testimony.

Anaesthetic management of a patient with Fontan physiology for electrophysiology study and catheter ablation.

The success of the Fontan procedure for congenital single ventricle anatomy has resulted in adult patients with Fontan physiology requiring anaesthesia for cardiac and non-cardiac procedures. We present the perioperative management of a patient with Fontan physiology who underwent electrophysiological study with radiofrequency ablation for atrial tachycardia under general anaesthesia. Good communication between the multidisciplinary teams, a detailed understanding of the patient's complex cardiac anatomy and physiology, as well as the ability to recognise and manage perioperative complications all play a vital role for a successful outcome.

Associations Between the DSM-5 Section III Trait Model and Impairments in Functioning in Singaporean College Students.

The Alternative Model for Personality Disorders (AMPD) in Section III of the Diagnostic and Statistical Manual of Mental Disorders, fifth edition, recommends the joint consideration of personality disorder severity (i.e., dysfunction) and style (i.e., trait profile) in personality disorder diagnosis. The current study examined the association between maladaptive personality dysfunction and traits using a Singaporean student sample (N = 360). A subsample (n = 151) had informant ratings of personality traits on target participants. Results indicated that dysfunctions and traits were substantially correlated, calling into question their distinctiveness. However, the overlap was less pronounced when informant ratings were used. Consistent with prior research, the validity of the PID-5 trait model appeared to be supported, as observed in the meaningful differential relations with different impairment outcomes. These findings represent a preliminary yet critical test of the generalizability of the AMPD to a non-Western cultural group.
