How Infants Direct Their Gaze to Faces in the Presence of Other Objects: The Development of Face Preference Between 4 and 7 Months After Birth

ABSTRACTFrom early in development, infants process faces in their environment differentially from other items. By around 6 months of age, they are able to orient toward faces in the presence of distractor items. This paper aimed to assess whether this preferential looking toward faces was observable prior to 6 months of age, and whether there were developmental trends. We assessed this using the face pop‐out task, a free viewing eye‐tracking experiment in which infants viewed arrays containing an image of a face, alongside four distractor items. We assessed whether infants at 4, 5, 6 and 7 months (n = 1585 participants) differed in the proportion of first looks, total dwell time, and frequency of fixations to faces compared to other items. All three outcome variables were significantly higher toward faces than toward any of the other items in all the age groups. Moreover, there were age‐related differences across all measures—the older the infants were, the more pronounced their face preferences were. These age‐related differences could not be attributed to differences in data quality, and thus suggest that face preference is observable at 4 months of age but shows a strong development until 6 months.

Misperception of the facial appearance that the opposite-sex desires.

Thin and muscular have been characterised as body shape ideals for women and men, respectively, yet each sex misperceives what the other sex desires; women exaggerate the thinness that men like and men exaggerate the muscularity that women like. Body shape ideals align with stereotypic perceptions of femininity in women and masculinity in men. The present study investigates whether misperception of opposite-sex desires extends to femininity/masculinity in facial morphology. We used interactive 3D head models to represent faces varying in sexual dimorphism. White European heterosexual men and women were asked to choose their own and ideal face shape, the ideal shape of a short- and a long-term partner, and the face shape they thought the opposite sex would most like for a short- and a long-term partner. Women overestimated the facial femininity that men prefer in a partner and men overestimated the facial masculinity that women prefer in a partner. The discrepancy between own and ideal sexual dimorphism (an index of appearance dissatisfaction) covaried with by the misperception of what the opposite-sex desires. These results indicate misperception of opposite-sex facial preferences and that mistaken perceptions may contribute to dissatisfaction with own appearance.

Evaluating The Challenges That Nursing Students Faced With E- Learning During Covid-19 Pandemic

Introduction: Higher education institutions have been extremely affected by the Covid-19 pandemic. E-learning was the option used during lockdown in Albania and all around the world. Students were obligated to interrupt face to face education and clinical practice. This situation put the academic institutions in difficulty because both lecturers, students and other members of university institutions have to face a new way of teaching and learning. The aim of this study is to evaluate the challenges that nursing students faced during online learning because of lockdown and offer solution to improve this way of teaching and learning. Methods: This is a cross-sectional study. The study was conducted at Faculty of Technical Medical Science, Tirana. Subjects: the population study were students of the third and fourth year of bachelor degree, master of science and professional master. They took part by voluntary way. Participants completed a self -administrated questionnaires. In this questionnaire there were questions related the efficiency of e-learning and problems related with it. Results: The highest percentage of students presented problems with the Internet during the study period; 40.1% of them did not agree to online learning; high percentage of results related to the inappropriateness of the online semester methodology; 46% of the interviewers do not believe in the continuation of online learning. Regarding the health problems, the students presented the highest percentage of headaches and stress. A significant association between gender, study field and stress level with p=0.000, p=0.002. The results are reported using descriptive statistics with counts and absolute percentages. A chi-square test was used to establish associations between variables. A p value < 0.05 was considered significant. Statistical analysis was performed using the SPSS 20.0 statistical package. Conclusions: Students showed no preference for distance learning versus face to face. Teachers should take appropriate steps to enhance e-teaching to improve it.

Short-latency preference for faces in primate superior colliculus depends on visual cortex

Face processing is fundamental to primates and has been extensively studied in higher-order visual cortex. Here, we report that visual neurons in the midbrain superior colliculus (SC) of macaque monkeys display a preference for images of faces. This preference emerges within 40ms of stimulus onset-well before "face patches" in visual cortex-and, at the population level, can be used to distinguish faces from other visual objects with accuracies of ∼80%. This short-latency face preference in SC depends on signals routed through early visual cortex because inactivating the lateral geniculate nucleus, the key relay from retina to cortex, virtually eliminates visual responses in SC, including face-related activity. These results reveal an unexpected circuit in the primate visual system for rapidly detecting faces in the periphery, complementing the higher-order areas needed for recognizing individual faces.

Exposure to the parents' speech is positively associated with preterm infant's face preference.

The parents' presence and involvement in neonatal care is a promising approach to improve preterm infants' neurodevelopmental outcomes. We examined whether exposure to the parents' speech is associated with the preterm infant's social-cognitive development. The study included infants born before 32 gestational weeks in two neonatal units. Each infant's language environment was assessed from 16-hour recordings using Language Environment Analysis (LENA®). Parental presence was assessed with Closeness Diary for 14 days during the hospital stay. Attention to faces and non-face patterns was measured at the corrected age of seven months using an eye-tracking disengagement test. A total of 63 preterm infants were included. Infants were less likely to disengage their attention from faces (M = 0.55, SD = 0.26) than non-face patterns (M = 0.24, SD = 0.22), p < 0.001, d = 0.84. Exposure to the parents' speech during the neonatal period was positively correlated with the preference for faces over non-face patterns (rs = 0.34, p = 0.009) and with the preference for parents over unfamiliar faces (rs = 0.28, p = 0.034). The exposure to the parents' speech during neonatal hospital care is a potential early marker for later social development in preterm infants. The exposure to the parents' speech during neonatal intensive care is a potential early marker for optimal social-cognitive development in preterm infants. This is the first study to show an association between parental vocal contact during neonatal intensive care and early social development (i.e., face preference), measured at seven months of corrected age. Our findings suggest that we should pay attention to the parents' vocal contact with their child in the neonatal intensive care unit and identify need for tailored support for face-to-face and vocal contact.

Attention toward Social and Non-Social Stimuli in Preschool Children with Autism Spectrum Disorder: A Paired Preference Eye-Tracking Study.

Different dimensions of visual attention to social (human faces) and non-social stimuli (objects) were assessed in 19 preschool children with Autism Spectrum Disorder (ASD) and 19 typically developing (TD) age, gender, and IQ-matched controls through an original paired preference eye-tracking paradigm. The present study found a significantly reduced attentional bias toward human faces in children with ASD compared to TD controls. The analysis of the total fixation time showed a significantly reduced preference for faces in children with ASD compared to TD children. Moreover, while TD children showed a significant preference for the face over the object, children in the ASD group observed the two paired pictures for a similar amount of time, thus showing no preference. Besides, children with ASD paid significantly more sustained attention to the objects than TD children. Children in the TD group paid greater sustained attention to the faces over the objects, while children in the ASD group did not differentiate between objects and faces. Finally, an age effect was found in ASD, as younger children in the group tended to prefer objects and to show more sustained attention towards them. Overall, these findings add to the literature on anomalies in attention toward social and non-social stimuli in young children with ASD compared to their TD counterparts. These results are discussed in the light of previous studies and suggest possible directions for future research.

A theory of emotion based on a universal model

The complexity of emotions has thus far limited our understanding of them. To obtain a clear understanding of the nature of emotion, this paper proposes a novel emotion theory and establishes a universal model of the conscious world in the human brain, the substanguage and interaction model (SIM). Based on an analysis of the possibilities of the interaction process in the SIM, two basic emotions that are indecomposable factors within all emotions—hope and fear—are identified. A questionnaire survey reveals that this basic emotion exhibits high acceptability. Based on emotion theory, this paper reasonably explains the phenomena of facial attraction and infantile facial preference and discusses the psychological reasons for phonocentrism, the phenomenon of preferring the spoken word over the written word. In addition, this paper explores the possibility of artificial intelligence possessing self-emotions. Emotions are relevant to many areas of human knowledge, as well as to everyone’s daily lives, and the simple, clear way to understand emotions provided in this paper may be instructive for everyone.

Judging a book by its cover: Fund investors’ physical attractiveness stereotypes and investor behavior

This paper documents that fund investors’ behavior is biased by the physical attractiveness stereotypes that they hold about fund managers. In an experimental setting, we find that although there is no information about highly attractive fund managers outperform their peers, respondents still perceive highly attractive managers to possess superior management skills and are willing to allocate more money to their managed funds. We further find that provision of information in contrast to the assumptions associated with physical attractiveness stereotypes diminishes the bias in investor behavior. When less attractive managers have historical returns that are 4% higher than more attractive managers, investors’ preference for attractive faces is overridden. Empirical evidence obtained using fund market data is consistent with our experimental results.

Adoption by olive baboons (Papio anubis) of newly constructed electricity pylons as sleeping sites in Laikipia, Kenya.

Olive baboons (Papio anubis) use fixed, secure, and naturally occurring sleeping sites such as tall trees and rocky cliffs, as protection from predators and often show a selection preference for particular trees or rocky cliff faces. We documented olive baboons' adoption of recently constructed high-tension electrical transmission towers (pylons) as a novel type of sleeping site in Laikipia, Kenya. The use of pylons suggests that the greatest potential benefits may include reduced parasite exposure and predation avoidance. Thermoregulation and feeding efficiency are not supported as benefits because pylons increase baboons' exposure to wind and cool nighttime temperatures and the pylons were constructed in locations independent of established feeding sites. These observations advance our understanding of olive baboon sleeping site selection in a changing landscape.

Sustained looking at faces at 5months of age is associated with socio-communicative skills in the second year of life.

Efficiently processing information from faces in infancy is foundational for nonverbal communication. We studied individual differences in 5-month-old infants' (N=517) sustained attention to faces and preference for emotional faces. We assessed the contribution of genetic and environmental influences to individual differences in these gaze behaviors, and the association between these traits and other concurrent and later phenotypes. We found an association between the mean duration of looking at a face (before looking away from it) at 5months and socio-communicative abilities at 14months (β=0.17, 95% CI: 0.08; 0.26, p<0.001). Sustained attention to faces predicted socio-communicative abilities over and above variance captured by mean fixation duration. We also found a statistically significant but weak tendency to prefer looking at smiling faces (relative to neutral faces), but no indication that variability in this behavior was explained by genetic effects. Moderate heritability was found for sustained attention to faces (A=0.23, CI: 0.06; 0.38), while shared environmental influences were non-significant for both phenotypes. These findings suggest that sustained looking at individual faces before looking away is a developmentally significant 'social attention' phenotype in infancy, characterized by moderate heritability and a specific relation to later socio-communicative abilities.

Distribution pattern of arthropods and their ecological interactions on the leaf surfaces of Terminalia argentea saplings.

Terminalia argentea tree, native to Brazil, is widely used in landscaping, recovering degraded areas, its wood, coal production, and the bark or leaf extracts has medicinal use. Despite of its importance, the arthropod fauna associated to this plant and its interspecific relationships still needs further studies. The objectives of this study were to evaluate the arthropods, their ecological indices and the distribution in the leaf faces on T. argentea saplings. The numbers of phytophagous insects (e.g., Cephalocoema sp.), pollinators (e.g., Tetragonisca angustula), and natural enemies (e.g., Oxyopidae), and their ecological indices (e.g., species richness), were higher on the adaxial leaf faces on T. argentea saplings. Aggregated distribution of phytophagous insects (e.g., Aphis spiraecola), pollinators (e.g., Trigona spinipes), and natural enemies (e.g., Camponotus sp.) on T. argentea saplings was observed. Abundance, diversity, and species richness of natural enemies correlated, positively, with those of phytophagous and pollinators insects. Predators and tending ants followed their prey and sucking insects, respectively. Tending ants protected sucking insects against predators, and reduced chewing insects. The high number of Cephalocoema sp. on T. argentea saplings is a problem, because this insect can feed on leaves of this plant, but its preference for the adaxial leaf face favors its control. The aggregation behavior of arthropods on T. argentea saplings favors the control of potential pests of this plant. There seems to be competition between tending ants for space and food resources on T. argentea saplings.

Asymmetric cycloadditions, diels-alder and cyclopropanation transformations, with (S)-Benzyl N-2-trifluoroacetamidoacrylyl oxazolidinone

Asymmetric transformations to access derivatives of amino acids offer useful approaches to intermediates for target directed synthesis and for medicinal agents. Two new selective transformations are reported using S-benzyl acetamidoacrylate oxazolidinone 1 include Diels-Alder [4 + 2]-cycloaddition with cyclopentadiene and cyclopropanation via aryl tosyl hydrazones. Use of titanium (IV) chloride at room temperature (3 h) with 1 and cyclopentadiene generated the norbornene amino acyloxazolidinone product 6 (82 %) with high dienophile facial preference and 2:1 exo over endo selectivity. Cyclopropanation of 1 with phenyl tosyl hydrazone under phase transfer conditions at 60 °C gave product 8 (71 %) with 3:1 E to Z selectivity. Observed selectivity is consistent with proposed transition states of metal chelates of 1 in low energy conformation.

Asexual individuals report high preferences for femininity in male and female faces

ABSTRACT Preferences for sexual dimorphism in male and female faces can vary based on the viewers’ gender, sexual orientation, and intensity of sexual desire. Asexual individuals, who experience little to no sexual attraction, may display different preferences for sexual dimorphism than has been observed in allosexual samples. Researchers have hypothesised that gender conformity may likewise impact preferences for sexual dimorphism. Participants (N = 182) recruited from an online asexual community provided demographic information and responded to measures of romantic attraction, sexual attraction, and conformity with male and female gender norms before they indicated their preference for male and female faces that were digitally altered to be more or less sexually dimorphic. Regardless of gender, asexual participants displayed a high preference for femininity in male and female faces. Preferences for sexual dimorphism displayed complex, and inconsistent associations with reported romantic and sexual attraction, and with conformity to feminine gender norms. This is the first report of preferences for facial sexual dimorphism and assessment of the role of gender conformity in an asexual population. This research adds to our understanding of the role of sexual attraction in predicting preferences for sexual dimorphism in faces.

Toddlers’ sensitivity to dominance traits from faces

In adults, seeing individual faces is sufficient to trigger dominance evaluations, even when conflict is absent. From early on, infants represent dyadic dominance relations and they can infer conflict outcomes based on a variety of cues. To date, it is unclear if toddlers also make automatic dominance trait evaluations of individual faces. Here we asked if toddlers are sensitive to dominance traits from faces, and whether their sensitivity depends on their face experience. We employed a visual preference paradigm to study 18- and 24-month-old toddlers’ sensitivity to dominance traits from three types of faces: artificial, male, female. When presented with artificial faces (Experiment 1), 18- and 24-month-olds attended longer to the non-dominant faces, but only when they were in upright orientation. For real male faces (Experiment 2), toddlers showed equivalent looking durations to the dominant and non-dominant upright faces. However, when looking at female faces (Experiment 3), toddlers displayed a visual preference for the upright non-dominant faces at 24 months. To our knowledge, this is the first study to show that toddlers already display sensitivity to facial cues of dominance from 18 months of age, at least for artificial face stimuli.

Early Communicative Development in Williams Syndrome: A Longitudinal Case Study.

Individuals with Williams Syndrome (WS) have a specific and atypical neuropsychological profile, where language is above what is expected for their mental age, although it shows a late onset. There exists only one longitudinal study in infants younger than 20 months old with WS about early language precursors (joint attention, referential and instrumental behaviors, pointing gesture, verbal tags). The aim of this investigation is to evaluate these precursors in a baby with WS (8 to 18 months). Seven sessions of systematic observation were performed (six at baby's home, one at the Early Childhood Assistance center). The Battelle Developmental Inventory was used to evaluate the baby's development in two occasions (12 and 18 months). The results show an atypical development, and he is 5-6 months under what is expected for his chronological age. Attention towards objects prevails over preference for faces, but this one tends to increase. The pointing gesture does not emerge at the end of the observation period and therefore follows the first words that appear. The implications for the comprehension of the early linguistic profile in WS are discussed, as well as the implications for specific intervention strategies in the context of early childhood care.

Assessing Preferences of Facial Appearance in Transgender and Gender Nonbinary Patients

BackgroundWe designed a survey to evaluate preferences of facial appearance in transgender male (TM), transgender female (TF) and gender nonbinary patients to better inform goals of facial gender affirming surgery (FGAS) in gender nonbinary patients.MethodsTM/TF and nonbinary patients > 18 years old were identified via retrospective chart review and distributed an anonymized survey via email from October 3 to December 31, 2022. To assess facial preferences, AI-generated and open-source portraits were edited to create five image sets with a range of features from masculine to feminine for the forehead, mandible/chin and hairline. Data were analyzed using Fisher’s exact tests and ANOVA in R-Studio.ResultsSurvey response rate was 32% (180 patients identified via chart review, 58 respondents; TM = 5, TF = 39, nonbinary = 14). TM and TF patients as well as TF and nonbinary patients had significantly different preferences for all regions (p < 0.005; all series), while TM and nonbinary patients did not (p => 0.05; all series). TF patients consistently selected 4s with neutral or more feminine features. TM and nonbinary patients, however, demonstrated no consistent preference for either male or female features but rather a range of responses spanning extremes of both masculine and feminine options. When stratified by sex assigned at birth, nonbinary patients consistently identified preferences opposite to their assigned gender.ConclusionGender nonbinary and TM patients appear to have uniquely individual preferences regarding facial appearance that do not fit into classically masculine or feminine patterns/phenotypes. As a result, we recommend individualized preoperative planning for FGAS to achieve the optimal result in these patient populations.Level of Evidence IVThis journal requires that authors assign a level of evidence to each article.

Applying a drift diffusion model to test the effect of oxytocin on attentional biases in body dysmorphic disorder

Individuals with body dysmorphic disorder (BDD) display selective attentional biases to threat. Oxytocin is an endogenous neuropeptide proposed to modulate attentional salience in social contexts. We conducted a secondary analysis applying drift diffusion modeling (DDM) to test whether individuals with BDD would display an attentional bias to threat, and whether oxytocin would modulate this bias. Eighteen participants with BDD and 15 healthy controls received an oxytocin or placebo nasal spray during two study visits, in randomized order, and completed a modified spatial cueing paradigm. DDM successfully parsed distinct task components demonstrating a selective attentional bias to disgust versus neutral faces in BDD compared to controls in the placebo condition, and a main effect of oxytocin on exacerbating this bias across participants. There were no effects using mean reaction time measures. DDM may reveal insights about attentional biases by utilizing trial-wise information. Oxytocin may exacerbate attentional biases to threat in BDD. General scientific summaryDrift diffusion modeling successfully parsed distinct components of a modified spatial cueing task that assessed attentional biases in those with body dysmorphic disorder (BDD) and healthy controls that were missed in conventional analyses using mean reaction time measures. Individuals with BDD displayed an attentional preference for disgust versus neutral faces in the placebo condition, and oxytocin exacerbated this attentional bias.

Rapid face preference during visual object processing by the primate superior colliculus

Rapid face preference during visual object processing by the primate superior colliculus

Face preference detection task based on EEG energy analysis in the source domain.

Facial stimulation can produce specific event-related potential (ERP) component N170 in the fusiform gyrus region. However, the role of the fusiform gyrus region in facial preference tasks is not clear at present, and the current research of facial preference analysis based on EEG signals is mostly carried out in the scalp domain. This paper explores whether the region of the fusiform gyrus is involved in processing face preference emotions in terms of the distribution of energy over the source domain, and finds that the pars orbitalis cortex is most energetically active in the face preference task and that there are significant differences between the left and right hemispheres.Clinical Relevance- The role of pars orbitalis in facial preference may help doctors determine whether the pars orbitalis cortex is lost in clinical practice.

The role of scenic context on upright face preference in infancy.

Scenic information plays an important role in face processing, whereas it has received limited attention in the field of developmental research. In the current study, we investigated whether infants, like adults, utilize scenic information for face processing by the preferential-looking method. In Experiment 1, we examined 4-5 and 6-7-month-olds' visual preferences for upright faces compared to inverted faces in two surrounding scene conditions: intact (in which a face occurs in an intact scene) and scrambled (in which a face occurs in a jumbled scene). We found that 6- to 7-month-olds preferred the upright face in the intact scene, but not in the scrambled scene. Meanwhile, 4- to 5-month-olds showed significant upright face preference in both scenes. The results of Experiment 2 ruled out the possibility that the lack of preference for upright faces in the scrambled scene in 6- to 7-month-olds resulted from more distraction by the scrambledness of the image than occurs with 4- to 5-month-olds, by showing no developmental changes in preference either for the scrambled images or the intact images when faces did not appear. Our results suggest that infants aged 6 months or more utilize scenic information for face processing.
