Face Masks Bolsters the Characteristics From Looking at a Face Even When Facial Expressions Are Impaired

Face masks impact social interactions because emotion recognition is difficult due to face occlusion. However, is this enough to conclude that face masks negatively impact social interactions? We investigated the impact of face masks on invariant characteristics (sex, age), trait-like characteristics (trustworthiness, attractiveness, and approachability), and emotional expressions (happiness and excitability). Participants completed an online survey and rated masked and no-masked faces. The same face remained masked or no-masked throughout the survey. Results revealed that, when compared to no-masked faces, masked happy faces appeared less happy. Face masks did not negatively impact the ratings of other characteristics. Participants were better at judging the sex of masked faces. Masked faces also appeared younger, more trustworthy, more attractive, and more approachable. Therefore, face masks did not always result in unfavorable ratings. An additional post hoc modeling revealed that trustworthiness and attractiveness ratings for masked faces predicted the same trait ratings for no-masked faces. However, approachability ratings for no-masked faces predicted the same trait ratings for masked faces. This hinted that information from masked/no-masked faces, such as from the eye and eye region, could aid in the understanding of others during social interaction. Future directions were proposed to expand the research.

COVID-19 and Dengue Co-infection in a Young Girl: A Case Report

During COVID-19 pandemic, the increasing incidence of dengue in Monsoon season has become a further threat especially in the dengue endemic countries of Southeast Asia like Bangladesh. Co-infection of dengue with COVID-19 has created a number of practical challenges to combat the diseases simultaneously, especially at a time when healthcare resources are already exhausted tackling the COVID pandemic. We are presenting the case report of a 14 year old girl who suffered from both RT-PCR positive COVID -19 infection & NS1 positive Dengue. She was managed in a Private Hospital of Dhaka as Dengue fever Group C (due to severe plasma leakage) with severe COVID-19 infection (as required oxygen therapy). She had a critical course of illness, having continued fever, cough, breathlessness, desaturation along with thrombocytopenia & plasma leakage. However, to our great satisfaction, the patient was ultimately improved & could be discharged in a happy face. Bangladesh J Medicine July 2022; 33(1) : 104-108

Faces and Orientational Metaphors: The Effects of Valenced Faces and Facial Manipulations on Neutral Targets

<p>Previous research has shown that there may be an association between affect (negative vs. positive) and vertical position (up vs. down) of stimuli. The following research aimed to investigate whether individuals show spatial biases, either up or down, when asked to respond to neutral targets after seeing valenced faces. The research also aimed to investigate what impact manipulating automatic facial mimicry responses would have on response times. The research was conducted over three experiments. In Experiment 1, participants responded to neutral targets in either high or low vertical positions on a computer screen that were preceded by happy and sad schematic faces. There were two facial manipulation conditions. One group held a straw between their lips to inhibit smiling and another group held a straw between their teeth to facilitate smiling. A third group performed the response task without a straw (control condition). The procedure of Experiment 2 was identical to Experiment 1 except the happy and sad schematic faces had additional internal facial features (noses, eyebrows) that varied across trials. For both Experiment 1 and 2, targets preceded by a happy face were responded to significantly faster. In Experiment 3, the procedure was identical to Experiments 1 and 2, except photographic images of happy, neutral, and sad expressions were used. Participants were significantly faster to respond to targets in the high vertical position. Participants were also faster to respond to targets in the control (no straw) condition than the other two straw conditions. In the inhibition smiling condition, participants were faster to respond to targets in the high vertical position than low vertical position after seeing a happy or neutral face. These findings indicate that there may be an association between valenced faces and vertical selective attention that is consistent with orientational metaphors (positive = up), but further research is needed to clarify this.</p>

Bi-directional relations between maternal anxiety and infant affect-biased attention across the first 24-months of life

Introduction: Patterns of affect-biased attention are related to anxiety and anxiety risk. However, little is known regarding how affect-biased attention develops. Recent work suggests relations with both infant temperamental negative affect and maternal anxiety. The current paper examines potential bi-directional relations between infant attention, infant negative affect, and maternal anxiety to better understand a developmental process that may precede the emergence of anxiety. Method: Infant-mother pairs (N = 333) participated in a multi-site, longitudinal study providing eye-tracking and questionnaire data when infants were 4-, 8-, 12-, 18- and 24-months. A random intercepts cross-lag panel model assessed bi-directional relations between infant attention, infant negative affect and maternal anxiety.Results: Within-person deviations in maternal anxiety were prospectively, negatively related to within-person deviations in infant attention to angry face configurations at every assessment and within-person deviations in infant attention to happy face configurations at the final two assessments. Additionally, within-person deviations in infant negative affect were prospectively, positively related to within-person deviations in infant attention to angry face configurations at 12- and 18-months. Consistent bi-directional relations were not found.Conclusion: Our results suggest that infants do not display a stable bias to threat in the first 24 months of life. Rather, individual differences, in this case maternal anxiety and infant negative affect, shape patterns of attention biases over time. The current results provide an initial understanding of bi-directional relations in affect-biased attention development.

A happy family: systematic revision of the endemic Theridion spiders (Araneae, Theridiidae) of the Hawaiian Islands

Since the description in 1900 of the iconic Happy Face spider, Theridion grallator, Simon, along with nine relatives, the Theridion fauna of the Hawaiian Islands has remained unstudied. Here, we present a systematic revision of the Hawaiian Theridion, which includes the examination of abundant material collected during the last 50 years, with scanning of the genitalia of several species using SEM techniques, and a cladistic analysis based on 22 morphological characters, to provide a first hypothesis of the phylogenetic structure of the group. We describe eight new species, namely T. ariel, sp. nov., T. caliban, sp. nov., T. ceres, sp. nov., T. ferdinand, sp. nov., T. juno, sp. nov., T. miranda, sp. nov., T. prospero, sp. nov. and T. sycorax, sp. nov. Additionally, we provide new diagnoses for former species and illustrate and describe for the first time the male of T. kauaiense Simon, 1900 and the female of T. praetextum Simon, 1900. We further propose that T. campestratum Simon, 1900 is a junior synonym of T. melinum Simon, 1900 and T. praetextum concolor Simon, 1900 is a junior synonym of T. praetextum. Finally, we provide updated information on the distribution of the species. Most species are easily diagnosed based on the male and female genitalia, but we also reveal the existence of somatic characters that differ among species, such as the body size and the shape and size of the chelicerae, which may have played a role in the diversification and coexistence of some of the species. The preferred cladogram from the cladistic analysis, although compatible with a progression rule, also suggests a complex pattern of multiple back and forward colonisations, albeit most of the clades are poorly supported.

Performance Differences Between Native and Non-Native Speakers on a New Happy–Sad Executive Function Measure

Objective The happy–sad task adapts the classic day–night task by incorporating two early acquired emotional concepts (“happy” and “sad”) and demonstrates elevated inhibitory demands for native speakers. The task holds promise as a new executive function measure for assessing inhibitory control across the lifespan, but no studies have examined the influence of language of test administration on performance. Method Seventy adult native English speakers and 50 non-native speakers completed the computerized day–night and the new happy–sad tasks administered in English. In two conditions, participants were categorized pictorial stimuli either in a congruent manner (“happy” for a happy face) or in a more challenging, incongruent manner (“sad” for a happy face). Lexical decision performance was obtained to estimate levels of English language proficiency. Results Native speakers and non-native speakers performed comparably except for the critical incongruent condition of the happy–sad task, where native speakers responded more slowly. A greater congruency effect for the happy–sad task was found for native than for non-native speakers. Lexical decision performance was associated with performance on the challenging incongruent conditions. Conclusion This study reinforced the usefulness of the happy–sad task as a new measure in evaluating inhibitory control in adult native-speakers. However, the language of test administration needs to be considered in assessment because it may lead to performance differences between native and non-native speakers.
