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.

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.

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.

Researchers Deserve a Better Critique: Response to.

This commentary addresses the critique by Larzelere, Gunnoe, Roberts, and Ferguson (2017: Marriage & Family Review, 53, 24-35) ostensibly concerning the quality of research on "positive parenting" but actually critiquing physical punishment research. The critique revealed that the authors have a poor understanding of positive parenting. After explicating the different meanings of that term and describing what positive parenting is, we then address each of their four critiques of the physical punishment research. Each critique was flawed in multiple ways. After identifying their errors and correcting misinformation, we then raise broader issues about children's right not to be hit and how professional organizations are increasingly recognizing the need and calling for an end to all physical punishment of children.
