RÉSUMÉ

Establishing and maintaining social relationships is a critical developmental milestone for adolescents and young adults and can be disrupted by childhood adversities. Adverse and positive childhood experiences (ACEs and PCEs, respectively) represent independent, yet critical, domains that support the exploration of positive and adverse childhood experiences (PACEs) as pathways to social connection. Recent research has examined the impact of COVID-19 on child development. The current study expands on existing research by examining the effects that PACEs clusters and high school enrollment during COVID-19 had on social connectedness. Young adults (N = 211; Mage = 20.97 years, SD = 2.14) completed an online survey examining social functioning and childhood experiences. Two measures comprised PACEs: Benevolent Childhood Experiences (BCEs) scale and Adverse Childhood Experiences questionnaire. An adapted Berkman-Syme Social Network Index measured social connection. High school enrollment during COVID-19 was determined by graduation year. Cluster analyses identified three PACEs profiles: (1) high BCEs/low ACEs (74.9%), (2) moderate BCEs/high ACEs (14.7%), and (3) low BCEs/moderate ACEs (10.4%). Regression analyses showed that High Risk/High Protection (ß = -3.326, p = .001) and Moderate Risk/Moderate Protection (ß = -4.845, p < .001) profiles had significantly fewer social connections than the Low Risk/High Protection profile. High school enrollment at the COVID-19 onset did not predict social connection (ß = 0.067, p = .305). Implications include clinicians considering PACEs when forming a holistic view of clients and integrating positive contexts into adversity research.

RÉSUMÉ

We present a scoping review of qualitative scholarly publications on sport and physical activity in secure custody facilities for young people published over a 22-year period, finding the literature remains geographically, substantively, and theoretically scant. We identify and assess predominant themes in the following four areas: (1) sport's potential contribution to young persons' rehabilitation and desistance; (2) the structure and organization of sport programs; (3) sport and coping with the experience of incarceration; and (4) other themes, including health outcomes and gender and race. Our scoping review provides a foundation for researchers and policymakers to advance knowledge about sport-based interventions in the lives of young people who are incarcerated.

RÉSUMÉ

BACKGROUND: In recent years, the escalating concern for neglected tropical diseases (NTDs) has been recognized as a pressing global health issue. This concern is acutely manifested in low- and middle-income countries, where there is an escalating prevalence among adolescents and young adults. The burgeoning of these conditions threatens to impair patients' occupational capabilities and overall life quality. Despite the considerable global impact of NTDs, comprehensive studies focusing on their impact in younger populations remain scarce. Our study aims to describe the global prevalence of neglected tropical diseases among people aged 15 to 39 years over the 30-year period from 1990 to 2019, and to project the disease burden of the disease up to 2040. METHODS: Annual data on incident cases, mortality, and disability-adjusted life years (DALYs) for NTDs were procured from the Global Burden of Disease Study 2019 (GBD 2019). These data were stratified by global and regional distribution, country, social development index (SDI), age, and sex. We computed age-standardized rates (ASRs) and the numbers of incident cases, mortalities, and DALYs from 1990 to 2019. The estimated annual percentage change (EAPC) in the ASRs was calculated to evaluate evolving trends. RESULTS: In 2019, it was estimated that there were approximately 552 million NTD cases globally (95% Uncertainty Interval [UI]: 519.9 million to 586.3 million), a 29% decrease since 1990. South Asia reported the highest NTD prevalence, with an estimated 171.7 million cases (95% UI: 150.4 million to 198.6 million). Among the five SDI categories, the prevalence of NTDs was highest in the moderate and low SDI regions in 1990 (approximately 270.5 million cases) and 2019 (approximately 176.5 million cases). Sub-Saharan Africa recorded the most significant decline in NTD cases over the past three decades. Overall, there was a significant inverse correlation between the disease burden of NTDs and SDI. CONCLUSION: NTDs imposed over half a billion incident cases and 10.8 million DALYs lost globally in 2019-exerting an immense toll rivaling major infectious and non-communicable diseases. Encouraging declines in prevalence and disability burdens over the past three decades spotlight the potential to accelerate progress through evidence-based allocation of resources. Such strategic integration could substantially enhance public awareness about risk factors and available treatment options.

RÉSUMÉ

OBJECTIVE: The aim is to evaluate the global, regional, and national trends in the burden of children and adolescents under 14 from 1990 to 2019, as well as future trend predictions. METHODS: In Global Burden of Disease (GBD), we reported the incidence, prevalence rate and the years lived with disability (YLDs), the incidence per 100,000 people, and the average annual percentage change (AAPC). We further analyzed these global trends by age, gender, and social development index (SDI). We use joinpoint regression analysis to determine the year with the largest global trend change. Bayesian age-period-cohort (BAPC) was used for predictions. RESULTS: From 1990 to 2019, the incidence rate, prevalence and YLDs of AD under 14 years old showed a downward trend. The incidence rate of AD among people under 5 years old has the largest decline [AAPC: -0.13 (95% CI: -0.15 to -0.11), P < 0.001]. The incidence rate, prevalence and YLDs of AD in women were higher than those in men regardless of age group. Regional, Asia has the highest AD incidence rate in 2019. National, Mongolia has the highest AD incidence rate in 2019. The largest drop in AD incidence rate, prevalence and YLDs between 1990 and 2019 was in the United States. CONCLUSION: From 1990 to 2019, the global incidence rate of children and adolescents under 14 declined. With the emergence of therapeutic drugs, the prevalence and YLDs rate declined significantly. From 2020 to 2030, there is still a downward trend.

RÉSUMÉ

In a prior study we demonstrated that the presence of face masks impairs the human capability of accurately inferring emotions conveyed through facial expressions, at all ages. The degree of impairment posed by face covering was notably more pronounced in children aged between three and five years old. In the current study, we conducted the same test as a follow-up after one year from the onset of the COVID-19 pandemic, when the requirement of wearing face masks was holding in almost all circumstances of everyday life when social interactions occur. The results indicate a noteworthy improvement in recognizing facial expressions with face masks among children aged three to five, compared to the pre-pandemic settings. These findings hold a significant importance, suggesting that toddlers effectively mitigated the social challenges associated with masks use: they overcame initial environmental limitations, improving their capability to interpret facial expressions even in the absence of visual cues from the lower part of the face.

RÉSUMÉ

When thinking about possibility, one can consider both epistemic and deontic principles (i.e., physical possibility and permissibility). Cultural influences may lead individuals to weigh epistemic and deontic obligations differently; developing possibility conceptions are therefore positioned to be affected by cultural surroundings. Across two studies, 251 U.S. and Chinese 4-, 6-, and 8-year-olds sampled from major metropolitan areas in Texas and the Hubei, Sichuan, Gansu, and Guangdong Provinces judged the possibility of impossible, improbable, and ordinary events. Across cultures and ages, children judged ordinary events as possible and impossible events as impossible; cultural differences emerged in developing conceptions of improbable events. Whereas U.S. children became more likely to judge these events possible with age, Chinese children's judgments remained consistent with age: Chinese 4- to 8-year-olds judged these events to be possible ∼25% of the time. In Study 2, to test whether this difference was attributable to differential prioritization of epistemic versus deontic constraints, children also judged whether each event was an epistemic violation (i.e., required magic to happen) and a deontic violation (i.e., would result in someone getting in trouble). With age, epistemic judgments were increasingly predictive of possibility judgments for improbable events for U.S. children, and decreasingly so for Chinese children. Contrary to our predictions, deontic judgments were not predictive. We propose that cultural valuation of norms might shape children's developing intuitions about possibility. We discuss our findings in light of three accounts of possibility conceptions, suggesting ways to integrate cultural context into each.

RÉSUMÉ

The collective behavior of animal groups emerges from the interactions among individuals. These social interactions produce the coordinated movements of bird flocks and fish schools, but little is known about their developmental emergence and neurobiological foundations. By characterizing the visually based schooling behavior of the micro glassfish Danionella cerebrum, we found that social development progresses sequentially, with animals first acquiring the ability to aggregate, followed by postural alignment with social partners. This social maturation was accompanied by the development of neural populations in the midbrain that were preferentially driven by visual stimuli that resemble the shape and movements of schooling fish. Furthermore, social isolation over the course of development impaired both schooling behavior and the neural encoding of social motion in adults. This work demonstrates that neural populations selective for the form and motion of conspecifics emerge with the experience-dependent development of collective movement.

RÉSUMÉ

Given the complexity of human social life, it is astonishing to observe how quickly children adapt to their social environment. To be accepted by the other members, it is crucial to understand and follow the rules and norms shared by the group. How and from whom do young children learn these social rules? In the experiments, based on the crucial role of affective social learning and dominance hierarchies in simple rule understanding, we showed 15-to-23-month-olds and 3-to-5-year-old children videos where the agents' body size and affective cues were manipulated. In the dominant rule-maker condition, when a smaller protagonist puts an object in one location, a bigger agent reacts with a positive reaction; on the contrary, when the smaller protagonist puts an object in another location, the bigger agent displays a negative reaction. In the subordinate rule-maker condition, the roles are shifted but the agents differ. Toddlers expect the protagonist to follow the rules (based on anticipatory looks), independent of the dominant status of the rule-making agent. Three-to-five-year-old pre-schoolers overall perform at the chance level but expect the protagonist to disobey a rule in the first trial, and obey the rule in the second trial if the rule-maker is dominant.

RÉSUMÉ

Belief in gendered social power imbalance (i.e. males are more powerful than females) leads to undesirable gender disparities, but little is known about the developmental origins of this belief, especially in Eastern cultures. We investigated the development onset of this belief by focusing on 4-7-year-old Japanese children while considering another belief (females are nicer than males) for comparison. In the dyadic context tasks, children saw pairs of animated characters depicting powerful-powerless or kind-unkind postures and judged the characters' gender (boy or girl). Results suggested both 'nice = female' and 'powerful = female' gender stereotypes in children. In the collective context tasks, children were presented with stories in occupational contexts, including multiple unspecified people and verbal cues, describing more explicitly the powerful and nice traits of the protagonists. The results replicated the 'nice = female' gender stereotype. Moreover, early 'powerful = male' gender stereotypes were seen in 6-year-old boys but not among girls in general. These findings demonstrate that Japanese children's beliefs regarding gender differences in power vary depending on the context in which male-female interactions are presented. Additionally, the study reveals that signs of the 'powerful = male' social power gender stereotype emerge around the age of 6.

RÉSUMÉ

PURPOSE: We know very little about Hispanic autistic children's response to intervention as, historically, Hispanic children are underrepresented in intervention studies. Pathways parent-mediated early autism intervention is one of the few naturalistic developmental behavioral interventions (NDBIs) that is contextually and linguistically responsive to Hispanic families. However, some child-centered NDBI strategies do not align with the Hispanic caregiving value of respeto. A child exhibiting respeto demonstrates affiliative obedience by displaying deference and respect toward adults. Furthermore, theories of the ontogeny of cultural learning suggest that certain levels of social development may be necessary to learn cultural values. The current study investigates (1) the relationship between Hispanic autistic children's social skills and affiliative obedience and (2) the efficacy of Pathways in improving affiliative obedience in Hispanic children. METHODS: This quasi-experimental design study used preexisting standardized test data and video recordings from 26 Hispanic participants who took part in a previous Pathways efficacy study. Recordings were coded for affiliative obedience and social connectedness. Residual change variables were used to measure progress from baseline to post-intervention, and correlation and hierarchical regression analyses were conducted to analyze the data. RESULTS: We found significant positive correlations between social skills and children's affiliative obedience for baseline and change variables. In addition, we found Pathways had a significant medium-large magnitude effect on change in affiliative obedience skills. CONCLUSION: This study highlights the benefits of NDBI interventions that advance social development in autistic children and support Hispanic parents in enculturating their children in the value of respeto.

RÉSUMÉ

For over a century, the evolution of animal play has sparked scientific curiosity. The prevalence of social play in juvenile mammals suggests that play is a beneficial behavior, potentially contributing to individual fitness. Yet evidence from wild animals supporting the long-hypothesized link between juvenile social play, adult behavior, and fitness remains limited. In Western Australia, adult male bottlenose dolphins (Tursiops aduncus) form multilevel alliances that are crucial for their reproductive success. A key adult mating behavior involves allied males using joint action to herd individual females. Juveniles of both sexes invest significant time in play that resembles adult herding-taking turns in mature male (actor) and female (receiver) roles. Using a 32-y dataset of individual-level association patterns, paternity success, and behavioral observations, we show that juvenile males with stronger social bonds are significantly more likely to engage in joint action when play-herding in actor roles. Juvenile males also monopolized the actor role and produced an adult male herding vocalization ("pops") when playing with females. Notably, males who spent more time playing in the actor role as juveniles achieved more paternities as adults. These findings not only reveal that play behavior provides male dolphins with mating skill practice years before they sexually mature but also demonstrate in a wild animal population that juvenile social play predicts adult reproductive success.

RÉSUMÉ

Triadic interactions, wherein infants coordinate attention between caregivers and objects of shared focus, are believed to facilitate infant learning, and emerge around 9-12 months of age (Carpenter et al., 1998). Sensorimotor decoupling, wherein infants look at one percept while manipulating another, or use each hand for different actions, was hypothesized (de Barbaro et al., 2016) to contribute to triadic skills by allowing infants to smoothly shift attention between objects and social partners. We explored the development of Hand-Hand (H-H) and Gaze-Hand (G-H) decoupling in 38 infants at 4, 6, and 9 months. We also tested contingencies between maternal behaviors and infant decoupling: i.e., whether decoupling events followed maternal object-directed actions. Both overall and contingent infant decoupling increased from 4 to 9 months. Decoupling rates (both G-H and H-H) predicted variance in infants' fine and gross motor scores. Contingent G-H decoupling at 6 months predicted BSID-III communication scores at 18 months. Thus the development of infant sensorimotor skills, including decoupling, allows infants to smoothly shift attention and participate in triadic interactions.

RÉSUMÉ

Attachment theory proposes that young children's experiences with their caregivers has a tremendous influence on how children navigate their social relationships. By the end of early childhood, intergroup contexts play an important role in their social life and children build strong ties to their ingroups. Although both domains relate to the same psychological processes-children's affective ties to others-surprisingly very little research has addressed how children's attachment relates to their intergroup attitudes and behavior. In this study, we investigate the link. For that purpose, 5-year-old children (n = 100) first underwent the German Attachment Story Completion Task (GEV-B). Then we allocated children into minimal groups based on T-Shirt color and assessed their intergroup attitudes and intergroup behavior. Results showed that while most children showed a strong and robust ingroup bias in their attitudes and behavior, children with an insecure-ambivalent attachment representation treated in- and outgroup similarly. Overall, this study provides novel perspectives on the relationship between children's attachment representation and their interactions in the social world. RESEARCH HIGHLIGHTS: This study provides novel insights into the relationship between children's attachment security and the development of intergroup bias in a minimal group context Children with secure, insecure-avoidant and disorganized attachment representation showed a strong intergroup bias in explicit attitudes and behavior Children with insecure-ambivalent attachment representation displayed no intergroup bias Insecure-ambivalent attachment representations might be detrimental to the formation of ingroup attachment.

RÉSUMÉ

Social-emotional learning (SEL) is a rapidly growing field of research that has garnered significant attention in recent years. Each facet of SEL research in fields such as education, mental health, and developmental research has used specific methodologies and terms in their narrow research focus. In education specifically, where the most SEL research has been produced, many frameworks have implementation requirements. The lack of a framework focused on overarching themes without implementation requirements prevents the fields from coming together to compile and compare research and progress to create parent-, adult-, or mental health-specific SEL programs. This paper provides a conceptual analysis of SEL, aimed at clarifying the concept and deconstructing its various facets. This framework is needed to acknowledge the many different terms and skills for the same principle while also narrowing down definitions for clarity. The resulting framework can be used as a basis for future research, practice, and policy discussions in the field.

RÉSUMÉ

Most studies of adolescent and adult behavior involved one age group of each, whereas the dynamic changes in brain development suggest that there may be behavioral flux in adolescence. In two studies, we investigated developmental changes in social reward motivation in female and male Long-Evans rats from prepuberty to early adulthood in a social operant conditioning task. Given the earlier onset of puberty in females than in males, we predicted the course of social reward development would differ between the sexes. Overall, the pattern of results from both studies suggests that the trajectory of social motivation across adolescence is characterized by upward and downward shifts that do not depend on the sex of the rats. During training, in both studies, the mean number of social gate openings and percentage of social gate openings was higher at P30 (prepubertal, early adolescence) and P50 (late adolescence) than at P40 (mid adolescence) and P70 (adulthood) irrespective of sex. Nevertheless, the specific age comparisons that were significant depended on the study. In both studies, P30 rats had greater levels of social motivation than did adults in accessing a social reward when increased effort was required (progressive ratio tests). In an extinction test, only P30 and P50 rats continued to show more nose-pokes at the previously social gate than at the nonsocial gate, suggesting resistance to extinction. The results highlight the importance of characterizing behavior at several timepoints in adolescence to understand the neural mechanisms, many of which show similar discontinuities as they develop across adolescence.

RÉSUMÉ

Infants are born into rich social networks and are faced with the challenge of learning about them. When infants observe social interactions, they make predictions about future behavior, but it is not clear whether these predictions are based on social dispositions, social relationships, or both. The current studies (N = 188, N = 90 males) address this question in 12-month-old infants and 16- to 18-month-old toddlers who observe social interactions involving imitation. In Studies 1 and 3, infants and toddlers expected that imitators, compared to non-imitators, would respond to their social partners' distress. Likewise, they expected the targets of imitation, compared to non-targets, to respond to their partner's distress. In Study 2, these expectations did not generalize to interactions with a new partner, providing evidence that infants learned about the relationships between individuals as opposed to their dispositions. In Study 3, infants did not make predictions about responses to laughter, suggesting that infants see imitation as indicative of a specific kind of social relationship. Together, these results provide evidence that imitative interactions support infants' and toddlers' learning about the social relationships connecting unknown individuals.

RÉSUMÉ

This study investigated the relationship between Metabolic Syndrome (MetS), sleep disorders, the consumption of some nutrients, and social development factors, focusing on gender differences in an unbalanced dataset from a Mexico City cohort. We used data balancing techniques like SMOTE and ADASYN after employing machine learning models like random forest and RPART to predict MetS. Random forest excelled, achieving significant, balanced accuracy, indicating its robustness in predicting MetS and achieving a balanced accuracy of approximately 87%. Key predictors for men included body mass index and family history of gout, while waist circumference and glucose levels were most significant for women. In relation to diet, sleep quality, and social development, metabolic syndrome in men was associated with high lactose and carbohydrate intake, educational lag, living with a partner without marrying, and lack of durable goods, whereas in women, best predictors in these dimensions include protein, fructose, and cholesterol intake, copper metabolites, snoring, sobbing, drowsiness, sanitary adequacy, and anxiety. These findings underscore the need for personalized approaches in managing MetS and point to a promising direction for future research into the interplay between social factors, sleep disorders, and metabolic health, which mainly depend on nutrient consumption by region.

RÉSUMÉ

Though common among humans, social play by adults is an uncommon occurrence in most animals, even between parents and offspring.1,2,3 The most common explanation for why adult play is so rare is that its function and benefits are largely limited to development, so that social play has little value later in life.3,4,5,6 Here, we draw from 10 years of behavioral data collected by the Kibale Chimpanzee Project to consider an alternative hypothesis: that despite its benefits, adult play in non-humans is ecologically constrained by energy shortage or time limitations. We further hypothesized that, since they may be the only available partners for their young offspring, mother chimpanzees pay greater costs of play than other adults. Our analysis of nearly 4,000 adult play bouts revealed that adult chimpanzees played both among themselves and with immature partners. Social play was infrequent when diet quality was low but increased with the proportion of high-quality fruits in the diet. This suggests that adults engage in play facultatively when they have more energy and/or time to do so. However, when diet quality was low and most adult play fell to near zero, play persisted between mothers and offspring. Increased use of play by adult chimpanzees during periods of resource abundance suggests that play retains value as a social currency beyond development but that its costs constrain its use. At the same time, when ecological conditions constrain opportunities for young to play, play by mothers fills a critical role to promote healthy offspring development.

RÉSUMÉ

PURPOSE: To analyze spatiotemporal trends in hospitalizations for cardiovascular diseases (CVD) sensitive to primary health care (PHC) among individuals aged 50-69 years in Paraná State, Brazil, from 2014 to 2019 and investigate correlations between PHC services and the Social Development Index. METHODS: We conducted a cross-sectional ecological study using publicly available secondary data to analyze the municipal incidence of hospitalizations for CVD sensitive to PHC and to estimate the risk of hospitalization for this group of diseases and associated factors using hierarchical Bayesian spatiotemporal modeling with Markov chain Monte Carlo simulation. RESULTS: There was a 5% decrease in the average rate of hospitalizations for PHC-sensitive CVD from 2014 to 2019. Regarding standardized hospitalization rate (SHR) according to population size, we found that no large municipality had an SHR >2. Likewise, a minority of these municipalities had SHR values of 1-2 (33%). However, many small and medium-sized municipalities had SHR values >2 (47% and 48%, respectively). A greater Social Development Index value served as a protective factor against hospitalizations, with a relative risk of 0.957 (95% credible interval, 0.929-0.984). CONCLUSIONS: The annual risk of hospitalization decreased over time; however, small municipalities had the greatest rates of hospitalization, indicating an increase in health inequity. The inverse association between social development and hospitalizations for CVD sensitive to PHC raises questions about intersectionality in health care.
