Interparental conflict dimensions and children's psychological problems: Emotion recognition as a mediator.

This study tested children's emotion recognition as a mediator of associations between their exposure to hostile and cooperative interparental conflict and their internalizing and externalizing symptoms. From 2018 to 2022, 238 mothers, their partners, and preschool children (Mage = 4.38, 52% female; 68% White; 18% Black; 14% Multiracial or another race; and 16% Latinx) participated in three annual measurement occasions. Path analyses indicated that Wave 1 observations of hostile interparental conflict predicted residualized increases in children's emotion recognition accuracy (i.e., angry, sad, and happy) at Wave 2 (ß = .27). Wave 2 emotion recognition, in turn, predicted residualized decreases in children's internalizing symptoms at Wave 3 (ß = -.22). Mediational findings were partly attributable to children's accuracy in identifying angry and high-intensity expressions.

White children's prosocial behavior toward White versus Black peers: The role of children's effortful control and parents' implicit racial attitudes.

White children's effortful control (EC), parents' implicit racial attitudes, and their interaction were examined as predictors of children's prosocial behavior toward White versus Black recipients. Data were collected from 171 White children (55% male, Mage = 7.13 years, SD = 0.92) and their parent in 2017. Prosocial behavior toward White peers was predicted by children's higher EC. When predicting prosocial behavior toward Black peers and prosocial disparity (the difference between White and Black recipients), parents' implicit racial attitudes moderated the relation between children's EC and children's prosocial behavior. Specifically, children's EC was positively associated with prosocial behavior toward Black peers (and negatively related to inequity in prosocial behavior) only when parents exhibited less implicit racial bias.

Do Appetite Traits Mediate the Link Between Birth Weight and Later Child Weight in Low-Income Hispanic Families?

Background: Birth weight and appetite traits (ATs) are important early life determinants of child weight and obesity. Objectives: The aim of this study is to examine whether (1) birth weight-for-gestational age z-scores (BWGAzs) were associated with ATs at child age 2 years and (2) ATs mediated the link between BWGAzs and weight-for-age z-scores (WFAzs) at child ages 3 and 4 years among Hispanic children. Methods: We conducted a secondary longitudinal analysis of data from the Starting Early Program of low-income, Hispanic mother-child pairs. ATs were assessed using the Child Eating Behavior Questionnaire at age 2 years. Child birth weight was obtained from medical records. Birth weight, sex, and gestational age were used to generate BWGAzs with Fenton growth curves. WFAz was calculated based on the CDC 2000 growth charts. Regression and mediation analyses were used to explore associations between BWGAzs, ATs, and WFAzs. Results: Infants with higher BWGAzs had significantly lower Satiety Responsiveness (B = -0.10) and Food Fussiness (B = -0.13) scores at age 2 years and higher WFAzs at ages 3 (B = 0.44) and 4 (B = 0.34) years. Lower Satiety Responsiveness at age 2 years was associated with higher WFAzs at ages 3 (B = -0.11) and 4 (B = -0.34; all p < 0.01) years. Lower Satiety Responsiveness partially mediated the positive relationship between birth weight and child WFAzs at ages 3 and 4 years. Conclusions: Children with higher birth weight and lower Satiety Responsiveness scores may be at higher risk of developing obesity in childhood. Further research is needed to understand the mechanisms through which birth weight influences child appetite. Clinical Trial Registration: ClinicalTrials.gov: NCT01541761.

Sociodemographic Correlates of Contemporary Screen Time Use among 9- and 10-Year-Old Children.

OBJECTIVE: To determine sociodemographic correlates of contemporary screen time use among a diverse population-based sample of 9- and 10-year-old children. STUDY DESIGN: In 2021, we analyzed cross-sectional baseline (2016-2018) data from the Adolescent Brain Cognitive Development study (n = 10 755). Multiple linear regression analyses were conducted to estimate associations between sociodemographic factors (sex, race/ethnicity, country of birth, household income, parental education) and 6 contemporary forms of screen time (television, videos [eg, YouTube], video games, social networking, texting, and video chat). RESULTS: On average, children reported 3.99 hours of screen time per day across 6 modalities, with the most time spent watching/streaming television shows/movies (1.31 hours), playing video games (1.06 hours), and watching/streaming videos (1.05 hours). On average, Black children reported 1.58 more hours of screen time per day and Asian children reported 0.35 less hours of screen time per day compared with White children (mean 3.46 hours per day), and these trends persisted across most modalities. Boys reported higher overall screen time (0.75 hours more) than girls, which was primarily attributed to video games and videos. Girls reported more time texting, social networking, and video chatting than boys. Higher income was associated with lower screen time usage across all modalities except video chat. However, in high-income households, Latinx children reported 0.65 more hours of screen time per day than White children. CONCLUSIONS: Given the sociodemographic differences in child screen use, guideline implementation strategies can focus on key populations, encourage targeted counseling by pediatricians, and adapt Family Media Use Plans for diverse backgrounds.

Physical Activity and Sedentary Behaviors among Chinese Children: Recent Trends and Correlates.

OBJECTIVE: This study was aimed at examining the trends and correlates of physical activity (PA) and sedentary behaviors among Chinese children. METHODS: A total of 4,341 subjects (6,936 observations) aged 6-17 years who participated in the China Health and Nutrition Survey (2004-2015) were included. Of the subjects, 41% participated in the survey twice or more. Random-effects ordinal regression models and repeated-measures mixed-effects models were used to examine the PA trends. Quantile regression models were applied to examine the factors influencing PA and sedentary behaviors. RESULTS: From 2004 to 2015, the prevalence of physical inactivity among Chinese children aged 6-17 years increased by 5.5% [odds ratio ( OR), 1.51; 95% confidence interval ( CI), 1.19-1.90; P < 0.001]. The PA volume declined by 5.8 metabolic equivalent of task-hr/week ( P < 0.001), and the time spent in sedentary behaviors increased by 1.8 hr/week ( P < 0.001). Age, ethnicity, and region showed significant effects on the PA volume across the quartiles ( P < 0.001). Across the quartiles, sedentary time was significantly higher in the children residing in urban areas ( P < 0.001) or areas with high urbanization levels ( P ≤ 0.005) than in their counterparts. CONCLUSIONS: A declining PA trend among Chinese children aged 6-17 years was observed from 2004 to 2015, and certain subgroups and geographical areas are at higher risk of physical inactivity.

Infant and Early Child Appetite Traits and Child Weight and Obesity Risk in Low-Income Hispanic Families.

BACKGROUND: Child appetite traits (ATs) are associated with later child weight and obesity risk. Less research has focused on ATs in low-income Hispanic children or included longitudinal associations with infant weight. OBJECTIVE: To determine stability of ATs during infancy and childhood and their relationship with subsequent weight and obesity risk at age 3 years among low-income Hispanic children. DESIGN: A secondary longitudinal analysis of data from the Starting Early Program randomized controlled obesity prevention trial. PARTICIPANTS/SETTING: Three hundred twenty-two low-income, Hispanic mother-child pairs enrolled between 2012 and 2014 in a public hospital in New York City. MAIN OUTCOME MEASURES: ATs, including Slowness in Eating, Satiety Responsiveness, Food Responsiveness, and Enjoyment of Food were assessed using the Baby and Child Eating Behavior Questionnaires at ages 3 months, 2 years, and 3 years. Main outcome measures were child standardized weight-for-age z score (WFAz) and obesity risk (WFA≥95th percentile) at age 3 years. STATISTICAL ANALYSES PERFORMED: AT stability was assessed using correlations and multilevel modeling. Linear and logistic regression analyses examined associations between ATs and child WFAz and obesity risk at age 3 years. RESULTS: There was limited stability for all ATs measured over time. During infancy, Slowness in Eating was associated with lower 3-year WFAz (B = -0.18, 95% CI -0.33 to -0.04; P = 0.01). At age 2 years, Slowness in Eating and Satiety Responsiveness were associated with lower WFAz (B = -0.29, 95% CI -0.47 to -0.12; P < 0.01; B = -0.36, 95% CI -0.55 to -0.17; P < 0.01) and obesity risk (adjusted odds ratio 0.49, 95% CI 0.28 to 0.85; adjusted odds ratio 0.61, 95% CI 0.38 to 0.99) at 3 years. Increased Slowness in Eating and Satiety Responsiveness over time were associated with lower 3-year WFAz (B = -0.74, 95% CI -1.18 to -0.2 [Slowness in Eating]; B = -1.19, 95% CI -1.87 to -0.52 [Satiety Responsiveness], both P values = 0.001). Higher Enjoyment of Food over time was associated with higher 3-year WFAz (B = 0.62, 95% CI 0.24 to 1.01; P = 0.002). CONCLUSIONS: Infants with lower Slowness in Eating and Satiety Responsiveness may have higher levels of obesity risk and need more tailored approaches to nutrition counseling and obesity prevention.

From Parent to Child to Parent: Associations Between Parent and Offspring Psychopathology.

Parental psychopathology can affect child functioning, and vice versa. We examined bidirectional associations between parent and offspring psychopathology in 5,536 children and their parents. We asked three questions: (a) are parent-to-child associations stronger than child-to-parent associations? (b) are mother-to-child associations stronger than father-to-child associations? and (c) do within- and between-person effects contribute to bidirectional associations between parent and offspring psychopathology? Our findings suggest that only within-rater bidirectional associations of parent and offspring psychopathology can be consistently detected, with no difference between mothers and fathers. Child psychopathology was hardly associated with parental psychopathology. No evidence for cross-rater child-to-parent associations was found suggesting that the within-rater child-to-parent associations reflect shared method variance. Moreover, within-person change accounted for a part of the variance observed.

Play in Mexican-American mothers and toddlers is frequent, multimodal, and rich in symbolic content.

Play offers rich opportunities for toddlers to develop motor, social, cognitive, and language skills, particularly during interactions with adult caregivers who may scaffold toddlers to higher levels of play than toddlers achieve on their own. However, research on play has narrowly focused on children from White, middle-income backgrounds, leaving a dearth of knowledge about dyadic play in diverse cultural communities. We videorecorded 222 Mexican-American mothers playing with their 2-year-old toddlers with a standard set of toys. Play behaviors were coded as nonsymbolic or symbolic (play type) and as expressed through manual, verbal, or multiple channels (play modality). Play between toddlers and mothers was frequent, high in symbolic content, and toddler play closely corresponded with mother play in type and modality: Toddlers' nonsymbolic play related to mothers' nonsymbolic play; toddlers' symbolic play related to mothers' symbolic play; toddlers' manual play related to mothers' manual play; and toddlers' multimodal play related to mothers' multimodal play. Play in Mexican-American mothers and toddlers is frequent, multimodal, and symbolically rich, offering new directions for future research and practice.

The relationship between fraternal birth order and childhood sex-atypical behavior among the Istmo Zapotec muxes.

Research on male androphilia (i.e., sexual attraction towards adult males) consistently finds that androphilic males tend to have more older biological brothers than males who are gynephilic (i.e., sexually attracted to adult females). This fraternal birth order effect (FBOE) has been well replicated among androphilic males who present publically in a male-typical (cisgender) and a female-typical (transgender) manner. There is some evidence that the FBOE is more pronounced among transgender androphilic males. However, no studies have directly compared both forms of male androphilia within the same culture. This study tested the FBOE, and its association with childhood sex-atypical behavior (CSAB), among the Istmo Zapotec of Oaxaca, Mexico, where both forms of male androphilia are referred to as a third gender, muxes. Our results indicated that both cisgender muxe nguiiu (n = 124) and transgender muxe gunaa (n = 120) were more likely to be later born among brothers than gynephilic men (n = 194). However, the number of older brothers did not differentiate between transgender and cisgender muxes, nor did it predict CSAB among muxes. These findings replicate the FBOE among both cisgender and transgender muxes but show no evidence that it is more pronounced among transgender androphilic males.

Grandmothers' Developmental Expectations for Early Childhood in Botswana.

Urban and rural grandmothers (n = 20) in Botswana participated in focus groups to learn their expectations for the acquisition of skills by preschool children. Their expectations for self-care, traditional politeness, and participation in household chores were dramatically earlier than developmental timetables reported for Western middle-class populations. There are some differences, however, in the urban and rural grandmothers' expectations. Rural grandmothers had earlier expectations for self-care skills and participation in household chores, and they had more specific expectations for mastering Setswana cultural customs. In addition, some urban grandmothers, who were generally more educated, described using more reciprocal communication, and they believed in playing with their grandchildren, whereas the rural grandmothers' communication was more instructional, and they insisted that children should play away from adults. Strikingly, there was no mention of school readiness goals or activities by either group, suggesting a "cultural misfit" between the standard early childhood curriculum, largely imported from the United States and other Western countries, and the cultural backgrounds of Batswana families. To create a more workable partnership between preschool teachers and grandparents-important caretakers of young children, both traditionally and currently-will require efforts to acknowledge and promote the values and expectations of both groups.

Emotion talk in Chinese American immigrant families and longitudinal links to children's socioemotional competence.

Parent emotion talk (ET), a type of emotion-related socialization practice, is theorized to foster children's emotion-related regulation and socioemotional skills. Yet, there has been limited research linking parent ET to children's effortful control, a top-down regulatory process. Despite the observed cultural differences in ET between Chinese and European American families, few researchers tested whether the socioemotional benefits of ET are generalizable to Chinese American families, an immigrant group with contrasting values in their heritage and host cultures. The present study examined Chinese American parents' ET, its associations with sociocultural factors, and prospective relations to school-age children's effortful control, sympathy, and socially appropriate behaviors. In a two-wave (1.5 years apart) longitudinal study of first- and second-generation Chinese American children (N = 258, age = 6-9 years at Wave 1, 52% from low-income families), the content and quality of parent ET (e.g., the overall quality of emotion talk, frequency of emotion explanations, emotion questions, and number of emotion words) was coded from a video-recorded shared book reading task. Children's effortful control, sympathy, and social behaviors were rated by parents, teachers, and children. Results showed that the Chinese American parents from lower socioeconomic status families, families with lower English proficiency, or more recent immigrants displayed lower ET. Parent ET was prospectively related to children's higher effortful control after controlling for stability, and higher effortful control was concurrently associated with children's higher sympathy and more socially appropriate behaviors. The findings provide empirical support for the socioemotional benefits of ET for school-age children in Chinese American immigrant families.

ADHD Parent and Teacher Symptom Ratings: Differential Item Functioning across Gender, Age, Race, and Ethnicity.

Parent and teacher ratings of the two attention-deficit/hyperactivity disorder (ADHD) symptom dimensions (i.e., inattention, hyperactivity-impulsivity) have been found to differ across child gender, age, race, and ethnicity. Group differences could be due to actual variation in symptomatic behaviors but also could be due to measurement items functioning differently based on child characteristics. This study extended prior investigations establishing measurement invariance at the symptom dimension and item levels, by examining possible measurement variance across child demographic characteristics at the item level (i.e., differential item functioning [DIF]) in two large national samples. Using the Rasch rating scale model (Andrich Psychometrika, 43, 561-73, 1978), we examined DIF of the 18 ADHD symptoms in samples of 2079 children (n = 1037 males) from 5 to 17 years old (M = 10.7; SD = 3.8) rated by parents and 1070 children (n = 535 males) aged from 5 to 17 years old (M = 11.5; SD = 3.5) rated by teachers. All but six ADHD symptom items showed DIF across child age, gender, race (Black vs. White), and ethnicity with more items showing DIF for age than for gender, race, or ethnicity. For child gender and age, more items showed DIF for parent than for teacher ratings. More items showed DIF across racial groups for teacher than for parent ratings. Only two parent- and teacher-rated items showed DIF for ethnicity. Implications of findings for practice, research, and future iterations of ADHD diagnostic criteria are discussed.

Cross-cultural variation in how much, but not whether, children overimitate.

Children from Western industrialized populations tend to copy actions modeled by an adult with high fidelity even if these actions are functionally irrelevant. This so-called overimitation has been argued to be an important driver of cumulative cultural learning. However, cross-cultural and developmental evidence on overimitation is controversial, likely due to diverging task demands regarding children's attention and memory capabilities. Here, children from a recent hunter-gatherer population (Hai||om in Namibia) were compared with urban Western children (Germany) using an overimitation procedure with minimal cognitive task demands. Although the proportion of children engaging in any overimitation was similar across the two populations, German overimitators copied irrelevant actions more persistently across tasks. These results suggest that the influence of culture on children's overimitation may be one of degree, not kind.

The development of social comparisons and sharing behavior across 12 countries.

Humans are social beings, and acts of prosocial behavior may be influenced by social comparisons. To study the development of prosociality and the impact of social comparisons on sharing, we conducted experiments with nearly 2500 children aged 3-12 years across 12 countries across five continents. Children participated in a dictator game where they had the opportunity to share up to 10 of their stickers with another anonymous child. Then, children were randomized to one of two treatments. In the "shared a little" treatment children were told that another child from their school had shared 1 sticker, whereas in the "shared a lot" treatment children were told that another child from their school had shared 6 stickers in the same game. There was a strong increase in baseline sharing with age in all countries and in both treatments. The "shared a lot" treatment had a positive treatment effect in increasing sharing overall, which varied across countries. However, cross-cultural comparisons did not yield expected significant differences between collectivist and individualist countries. Our results provide interesting evidence for the development of sharing behavior by age across the world and show that social information about the sharing of peers is important for children's decision making.

Playing with language, creating complexity: Has play contributed to the evolution of complex language?

We argue that enhanced play may have contributed to the emergence of complex language systems in modern humans (Homo sapiens). To support this idea, we first discuss evidence for an expansion of playing behavior connected to the extended childhood of modern human children, and the potential of this period for the transmission of complex cultural traits, including language. We then link two of the most important functions of play-exploration and innovation-to the potential for cumulative cultural evolution in general and for the emergence of complex language in particular. If correct, the shorter childhood of Neanderthals-involving restrictions on time to experiment and innovate-may have restricted their language (and other symbolic) system/s. Consequently, fully investigating the role that play may have had in the transmission of language and the development of symbolic cultures in both modern humans and Neanderthals provides a new avenue of research for Paleolithic archaeology and related disciplines.

Racial Differences Between Black Parents' and White Teachers' Perceptions of Attention-Deficit/Hyperactivity Disorder Behavior.

Previous research suggests there may be racial differences in how adults rate children's ADHD behavior. Differences in perceptions of Black parents and White teachers could have implications for ADHD diagnosis of Black children. This study compared ADHD ratings of Black parents to White teachers, and examined factors that may explain racial differences. Participants included 71 Black parents (65 women, 6 men; Mage = 33.92) and 60 White teachers (41 women, 19 men; Mage = 33.60), as well as a comparison group of 65 White parents (49 women, 16 men; Mage = 36.83). Participants watched video clips of children in classrooms and rated ADHD behaviors and ADHD likelihood. They then completed questionnaires regarding beliefs about ADHD stigma, verve (movement expressiveness), experiences with racial discrimination, and racial attitudes. White teachers rated Black boys' ADHD behaviors and their likelihood of having ADHD higher than Black parents. White teachers with more negative racial attitudes toward African Americans gave higher ADHD behavior and likelihood ratings to Black boys than did teachers with less negative racial attitudes. Across all participants, ADHD stigma beliefs and verve were not related to ratings of Black boys. Black parents with more experiences with racial discrimination gave higher ratings to Black boys' ADHD behaviors. Research is necessary to further explain the mechanisms by which discrepancies in ratings of Black boys' ADHD behaviors exist between Black and White adults to inform culturally sensitive assessment and diagnosis of ADHD in Black children.

Appetitive Traits and Weight in Children: Evidence for Parents' Controlling Feeding Practices as Mediating Mechanisms.

Children's food approach and food avoidance are appetitive traits with genetic or biological bases. Nonetheless, parents play a critical role in children's dietary intake through parenting and feeding practices. The present study tested parents' controlling feeding practices (i.e., restriction and pressure to eat) as mediating mechanisms between child appetitive traits and child BMI in an economically and ethnically diverse sample. Participants were 139 children aged 4 to 6 years (51.8% males, M = 4.77 years, SD = 0.84) and their parents. Results showed that restriction and pressure to eat mediated the relation between child food approach or food avoidance and child BMI. Mediation effects did not differ across poverty status or racial/ethnic groups. Also, the type of controlling feeding that parents exert related to children's weight status in diametrically different or opposite ways. Thus, food-related parenting appears to be a promising point of entry for childhood obesity prevention programs. Findings are consistent with a biopsychosocial model of the development of eating and weight in childhood which takes into account both parent and child behavior and characteristics and links child biology and behavior with psychosocial processes and environment.
