Leveraging an intensive time series of young children's movement to capture impulsive and inattentive behaviors in a preschool setting.

Studying within-person variability in children's behavior is frequently hindered by challenges collecting repeated observations. This study used wearable accelerometers to collect an intensive time series (2.7 million observations) of young children's movement at school (N = 62, Mage = 4.5 years, 54% male, 74% Non-Hispanic White) in 2021. Machine learning analyses indicated that children's typical forward acceleration was strongly correlated with lower teacher-reported inhibitory control and attention (r = -.69). Using forward movement intensity as a proxy for impulsivity, we partitioned the intensive time series and found that (1) children modulated their behavior across periods of the school day, (2) children's impulsivity increased across the school week, and (3) children with greater impulsivity showed greater variability in behavior across days.

Physical punishment and child outcomes: a narrative review of prospective studies.

Physical punishment is increasingly viewed as a form of violence that harms children. This narrative review summarises the findings of 69 prospective longitudinal studies to inform practitioners and policy makers about physical punishment's outcomes. Our review identified seven key themes. First, physical punishment consistently predicts increases in child behaviour problems over time. Second, physical punishment is not associated with positive outcomes over time. Third, physical punishment increases the risk of involvement with child protective services. Fourth, the only evidence of children eliciting physical punishment is for externalising behaviour. Fifth, physical punishment predicts worsening behaviour over time in quasi-experimental studies. Sixth, associations between physical punishment and detrimental child outcomes are robust across child and parent characteristics. Finally, there is some evidence of a dose-response relationship. The consistency of these findings indicates that physical punishment is harmful to children and that policy remedies are warranted.

Amount and type of physical activity as predictors of growth in executive functions, attentional control, and social self-control across 4 years of elementary school.

This paper used a nationally representative sample of children from the United States to examine the extent to which physical activity and sports participation may promote growth in children's executive functions (EFs), attention, and social self-control over time. Using data from the ECLS-K:2011 (N = 18,174), findings indicated that regular physical activity predicted growth in EFs and attention from 3rd to 4th grade (ßs = 0.03-0.05) but not from kindergarten to 1st grade. After controlling for the frequency of physical activity, participation in group sports predicted increases in EFs, attention, and social self-control during both periods (ßs = 0.02-0.04). Though modest in size, the findings suggest that encouraging children to engage in more frequent and more team-based activity will benefit the development of their EFs and related skills, and especially so for children in middle childhood.

Measuring children's behavioral regulation in the preschool classroom: An objective, sensor-based approach.

Children's abilities to regulate their behaviors are critical for learning and development, yet researchers lack an objective, precise method for assessing children's behavioral regulation in their everyday environments such as their classrooms. This study tested a sensor-based approach to assess preschool children's behavioral regulation objectively, precisely, and naturalistically. Children wore accelerometer devices as they engaged in center-based play in their preschool classrooms for roughly 45 min (N = 50 children, 48% female, mean age = 4.5 years). Set to record data each second, these devices collected information about children's movement (N = 140,564 observations). From these data, the authors extracted concrete behaviors hypothesized to index behavioral regulation and compared them with teacher and observer ratings of the same. Initiating movement more frequently, staying seated in activities for shorter amounts of time, and spending a greater amount of time in motion were related to lower ratings of attention and inhibitory control by teachers and by observers of classroom group time, median r = .45, p < .01. These same objectively measured behaviors showed only weak associations with children's performance on assessments of cognitive regulation, median r = .11, p = .47. The findings indicate that ambulatory accelerometers can capture movement-based indicators of children's behavioral regulation in the classroom setting and that performance on measures of cognitive regulation does not strongly predict children's behavior in the classroom. As an unobtrusive and objective measure, actigraphy may become an important tool for studying children's behavioral regulation in everyday contexts.

Parent involvement and children's academic achievement: Evidence from a census of public school students in Brazil.

In order to broaden findings beyond high-income countries, this study used path models to test associations between parent involvement and student achievement in Brazil using a 2017 census of public school students in fifth grade (N = 2,167,729, Mage  = 11, 49 % female, 44% Parda, 29% White, 11% Black, 3% Asian, 3% Indigenous) and ninth grade (N = 1,782,899, Mage  = 15, 51% female, 46% Parda, 29% White, 12% Black, 4% Asian, 3% Indigenous). Parent involvement showed positive associations with student reading and math achievement for fifth graders (ßs = .11 & .09) but essentially null associations for ninth graders (ßs = -.01). Students' homework completion mediated associations in both grades (ßs = .03). Parent education was not a strong moderator of associations.

Post-Pregnancy Factors Predicting Teen Mothers' Educational Attainment by Age 30 in Two National Cohorts.

Women who begin childbearing as teenagers attain lower levels of education than women who delay childbearing until age 20 and later. Little is known about post-pregnancy factors that predict educational attainment among teen mothers. The current study examined whether teen mothers' environment and experiences 2 years after their first birth contribute to their educational outcomes by age 30, net of selection factors associated with teenage childbearing. Data were from two cohorts, the National Longitudinal Surveys of Youth 1979 (N = 241) and 1997 (N = 378). Multinomial logistic regression modeling was used to assess associations of post-pregnancy factors with teen mothers' educational attainment. Having child care was associated with increased odds of attaining a high school diploma and of attending college in both cohorts. Providing regular and subsidized child care for teen mothers is an opportunity to support teen mothers in achieving higher levels of educational attainment.

It matters how you start: Early numeracy mastery predicts high school math course-taking and college attendance.

Using data from the Applied Problems subtest of the Woodcock-Johnson Tests of Achievement (Woodcock & Johnson, 1989/1990, Woodcock-Johnson psycho-educational battery-revised. Allen, TX: DLM Teaching Resources) administered to 1,364 children from the National Institute of Child Health and Human Development (NICHD) Study of Early Childcare and Youth Development (SECCYD), this study measures children's mastery of three numeric competencies (counting, concrete representational arithmetic and abstract arithmetic operations) at 54 months of age. We find that, even after controlling for key demographic characteristics, the numeric competency that children master prior to school entry relates to important educational transitions in secondary and post-secondary education. Those children who showed low numeric competency prior to school entry enrolled in lower math track classes in high school and were less likely to enrol in college. Important numeracy competency differences at age 54 months related to socioeconomic inequalities were also found. These findings suggest that important indicators of long-term schooling success (i.e., advanced math courses, college enrollment) are evident prior to schooling based on the levels of numeracy mastery.

Twin Differences in Harsh Parenting Predict Youth's Antisocial Behavior.

In the current study, we leveraged differences within twin pairs to examine whether harsh parenting is associated with children's antisocial behavior via environmental (vs. genetic) transmission. We examined two independent samples from the Michigan State University Twin Registry. Our primary sample contained 1,030 families (2,060 twin children; 49% female; 6-10 years old) oversampled for exposure to disadvantage. Our replication sample included 240 families (480 twin children; 50% female; 6-15 years old). Co-twin control analyses were conducted using a specification-curve framework, an exhaustive modeling approach in which all reasonable analytic specifications of the data are interrogated. Results revealed that, regardless of zygosity, the twin experiencing harsher parenting exhibited more antisocial behavior. These effects were robust across multiple operationalizations and informant reports of both harsh parenting and antisocial behavior with only a few exceptions. Results indicate that the association between harsh parenting and children's antisocial behavior is, to a large degree, environmental in origin.

Predictors and consequences of school mobility in middle childhood.

In this prospective longitudinal study (N = 1094, M age = 5.6 years to M age = 11.1 years), we examined family factors associated with school mobility and then asked if either a move during the previous year or cumulative moves across elementary school were related to child functioning. Family factors were not linked to a recent move or a single move, but changes in family income and household structure did predict higher odds of two or more moves in elementary school. There was no evidence that a recent move or a single move was related to children's academic or social functioning. Effects of two or more moves on child functioning were not significant after controlling for the number of analyses that were conducted. Taken together, school mobility during elementary school did not appear to be a pervasive risk although we were unable to study very high rates of school mobility because of very small sample sizes.

What Do Parents Want From Preschool? Perspectives of Low-Income Latino/a Immigrant Families.

With a qualitative approach drawing from four focus groups, this study explored what aspects of preschool are valued most by 30 low-income Latino/a immigrant parents with children enrolled in a state-funded preschool program in Texas. Beyond the push and pull factors of necessity, convenience, and supply, parents reported valuing the responsiveness of schools to families' needs and concerns, the provision of a safe and developmentally appropriate environment, the role of preschool in both care and education, the incorporation of parents within the school, and the school's capacity for developing parents' human and navigational capital. Even though parents saw great value in preschool preparing their children for school and helping themselves as parents, there was also fear and mistrust in neighborhood schools that was rooted in discrimination and long-term educational inequality.

School Corporal Punishment and Its Associations with Achievement and Adjustment.

Corporal punishment in public schools is legal in nineteen states in the U.S. Over 100,000 students are disciplined with corporal punishment in public schools each year. Little is known about the forms school corporal punishment takes or about how school corporal punishment relates to students' outcomes. This study reports results from an anonymous online survey of emerging adults (ages 18 to 23) in the 19 states where school corporal punishment is legal. Of the more than 800 participants, 16% revealed that they experienced school corporal punishment. Propensity score matching was used to equate those who had experienced school corporal punishment and those who had not on a range of covariates. In regression models, having ever experienced school corporal punishment was linked with lower high school GPA, higher current depressive symptoms, and greater likelihood of spanking their own children in the future.

Thresholds of Resilience and Within- and Cross-Domain Academic Achievement among Children in Poverty.

Growing up in poverty increases the likelihood of maladaptive development. Yet, some children are able to overcome the adversity of poverty and demonstrate resilience. Currently, there is limited agreement among researchers about how to operationalize resilience, both in terms of who should be the comparison group against whom at-risk children are compared and in terms of what developmental domains of resilience are most predictive of later positive development. The present study investigated how different thresholds and domains of resilience at school entry were associated with within-domain and cross-domain academic achievement across elementary school. Using a nationally representative and longitudinal sample, the results demonstrated that children who reached a high threshold of resilience at entry to kindergarten had similar mathematics and literacy achievement throughout elementary school as academically competent children not in poverty. Additionally, cross-domain associations were found for both mathematics and literacy resilience predicting later achievement. These findings have important research and intervention implications for promoting positive academic development among children in poverty.

Strengthening Causal Estimates for Links Between Spanking and Children's Externalizing Behavior Problems.

Establishing causal links when experiments are not feasible is an important challenge for psychology researchers. The question of whether parents' spanking causes children's externalizing behavior problems poses such a challenge because randomized experiments of spanking are unethical, and correlational studies cannot rule out potential selection factors. This study used propensity score matching based on the lifetime prevalence and recent incidence of spanking in a large and nationally representative sample ( N = 12,112) as well as lagged dependent variables to get as close to causal estimates outside an experiment as possible. Whether children were spanked at the age of 5 years predicted increases in externalizing behavior problems by ages 6 and 8, even after the groups based on spanking prevalence or incidence were matched on a range of sociodemographic, family, and cultural characteristics and children's initial behavior problems. These statistically rigorous methods yield the conclusion that spanking predicts a deterioration of children's externalizing behavior over time.

A Two Decade Examination of Historical Race/Ethnicity Disparities in Academic Achievement by Poverty Status.

Research on achievement gaps by race/ethnicity and poverty status typically focuses on each gap separately, and recent syntheses suggest the poverty gap is growing while racial/ethnic gaps are narrowing. In this study, we used time-varying effect modeling to examine the interaction of race/ethnicity and poverty gaps in math and reading achievement from 1986-2005 for poor and non-poor White, Black, and Hispanic students in three age groups (5-6, 9-10, and 13-14). We found that across this twenty-year period, the gaps between poor White students and their poor Black and Hispanic peers grew, while the gap between non-poor Whites and Hispanics narrowed. We conclude that understanding the nature of achievement gaps requires simultaneous examination of race/ethnicity and income.

A Short-Term Evaluation of a Hospital No Hit Zone Policy to Increase Bystander Intervention in Cases of Parent-to-Child Violence.

This study used a pre/post design to evaluate the implementation of a hospital-wide No Hit Zone (NHZ) bystander intervention around parent-to-child hitting. A total of 2,326 staff completed the pre-NHZ survey and received training about the NHZ policy; 623 staff completed the post-test survey 10 months later. A group of 225 parents participated in the pre-NHZ survey and a second group of 180 participated in the post-NHZ survey, also 10 months later. Compared to staff in the pre-NHZ group, staff in the post-NHZ group had more negative attitudes about spanking and more positive attitudes about intervention when parents hit children in the hospital. Few differences were found among the parent pre- and post-groups. This study demonstrated that NHZs are a feasible way to inform and train hospital staff in ways to intervene during incidents of parent-to-child hitting to promote a safe and healthy medical environment.

School corporal punishment in global perspective: prevalence, outcomes, and efforts at intervention.

School corporal punishment continues to be a legal means of disciplining children in a third of the world's countries. Although much is known about parents' use of corporal punishment, there is less research about school corporal punishment. This article summarizes what is known about the legality and prevalence of school corporal punishment, about the outcomes linked to it, and about interventions to reduce and eliminate school corporal punishment around the world.

Violence Exposure as a Mediator Between Parenting and Adolescent Mental Health.

For youth exposed to community violence, parenting has been found to play a significant role in protecting adolescents from associated mental health symptoms. Yet little is known about the potential of parenting to prevent such exposure in the first place and thereby reduce the likelihood of adolescents' mental health symptoms. This study examined two parental practices that have often been examined as moderators, but not yet as predictors, of youth exposure to community violence associations with adolescent mental health, namely parental control and parental harshness. Analyses of self-reported data from 908 adolescents (M age = 16.5, SD = 1.71; 52 % girls; 13 % non-Hispanic White) revealed that harsh parenting was indirectly associated with youth mental health symptoms through higher levels of exposure to community violence, whereas links between controlling parenting and mental health symptoms were either non-significant or mediated through lower levels of adolescent violence exposure. These findings highlight the potential positive role parental control may play by preventing adolescents from exposure to potentially dangerous situations. Conversely, our results suggest that harsh parenting appears to pose a risk for adolescents by driving youth away from the home environment and potentially into places where violence may be more prevalent.

Classroom Age Composition and the School Readiness of 3- and 4-Year-Olds in the Head Start Program.

The federal Head Start program, designed to improve the school readiness of children from low-income families, often serves 3- and 4-year-olds in the same classrooms. Given the developmental differences between 3- and 4-year-olds, it is unknown whether educating them together in the same classrooms benefits one group, both, or neither. Using data from the Family and Child Experiences Survey 2009 cohort, this study used a peer-effects framework to examine the associations between mixed-age classrooms and the school readiness of a nationally representative sample of newly enrolled 3-year-olds (n = 1,644) and 4-year-olds (n = 1,185) in the Head Start program. Results revealed that 4-year-olds displayed fewer gains in academic skills during the preschool year when they were enrolled in classrooms with more 3-year-olds; effect sizes corresponded to 4 to 5 months of academic development. In contrast, classroom age composition was not consistently associated with 3-year-olds' school readiness.

Chaotic Experiences and Low-Income Children's Social-Emotional Development.

Development in early childhood is increasingly likely to take place in multiple contexts. Continuity and discontinuity in children's experiences across multiple contexts have important implications for their development. This study examines the extent to which children experience chaos in their homes and in their preschool settings is linked with their social-emotional development over the course of the preschool year. Data from a large, representative sample of low-income preschool children attending Head Start was used to test a series of multi-level models. Children whose experiences of their homes were highly chaotic, regardless of the how chaotic their experiences of their classroom were, decreased in their social-emotional skills over the preschool year. Chaotic experiences in the home environment thus appear to have more influence on children's development than do chaotic preschool experiences.

Parent-Adolescent Conflict as Sequences of Reciprocal Negative Emotion: Links with Conflict Resolution and Adolescents' Behavior Problems.

Although conflict is a normative part of parent-adolescent relationships, conflicts that are long or highly negative are likely to be detrimental to these relationships and to youths' development. In the present article, sequential analyses of data from 138 parent-adolescent dyads (adolescents' mean age was 13.44, SD = 1.16; 52 % girls, 79 % non-Hispanic White) were used to define conflicts as reciprocal exchanges of negative emotion observed while parents and adolescents were discussing "hot," conflictual issues. Dynamic components of these exchanges, including who started the conflicts, who ended them, and how long they lasted, were identified. Mediation analyses revealed that a high proportion of conflicts ended by adolescents was associated with longer conflicts, which in turn predicted perceptions of the "hot" issue as unresolved and adolescent behavior problems. The findings illustrate advantages of using sequential analysis to identify patterns of interactions and, with some certainty, obtain an estimate of the contingent relationship between a pattern of behavior and child and parental outcomes. These interaction patterns are discussed in terms of the roles that parents and children play when in conflict with each other, and the processes through which these roles affect conflict resolution and adolescents' behavior problems.
