Article Synopsis
  • Children born preterm often struggle with self-regulation in toddlerhood, and this study looked into how their prematurity, supportive parenting, and brain development are linked.
  • The research involved 57 preterm toddlers (aged 15-30 months) and their caregivers, analyzing their performance on a problem-solving task along with MRI data gathered during sleep to assess frontal lobe gray matter volume (GMV).
  • Findings showed that as toddlers got older, they became more compliant with difficult tasks, with LPT toddlers engaging the most; additionally, increased parent support positively influenced brain development in extremely preterm toddlers, highlighting the importance of early parental interventions for better outcomes.

Background: Both transactional and common etiological models have been proposed as explanations of why externalizing behavior problems (EBP) and internalizing behavior problems (IBP) co-occur in children. Yet little research has empirically evaluated these competing theoretical explanations. We examined whether EBP and IBP are transactionally related at the within-child level while also identifying antecedents commonly associated with between-child differences in underlying stability of both EBP and IBP across elementary school.

Objective: To assess the feasibility and acceptability of an online parenting-skills program for caregivers of young children with traumatic brain injury (TBI). Positive parenting contributes to recovery following early TBI and social and emotional development in typically developing children. Yet, few interventions have been designed to support psychosocial recovery and subsequent development after early TBI.

Article Synopsis
  • Implicit bias in NICUs can lead to Black mothers, particularly those who are economically disadvantaged, feeling disregarded when advocating for their infants, negatively impacting communication and increasing maternal distress.
  • The study involved 33 diverse mothers in three Midwest NICUs and used a 14-item measure to assess their perceived power, efficacy of voice, and levels of distress compared to their White, higher-income counterparts.
  • Results showed that Black, economically disadvantaged mothers felt less empowered in communication with doctors and nurses, which correlated with higher levels of mental health issues, such as somatization and eating disorders.

Background: Neonatal intensive care unit (NICU) history, combined with systemic inequities for mothers of nondominant cultures and mothers who are socioeconomically disadvantaged, places infants at an extraordinary risk for poor developmental outcomes throughout life. Although receipt of early intervention (EI) is the best single predictor of developmental outcomes among children with and at risk for early developmental delays, mothers and infants with the greatest needs are least likely to receive EI. Mobile internet-based interventions afford substantial advantages for overcoming logistical challenges that often prevent mothers who are economically disadvantaged from accessing EI.

Academic achievement for young dual language learners (DLL) is a critically acknowledged problem of national significance that has been understudied. To address this shortage, this study evaluated the effectiveness of Preparing Pequeños, an integrated small-group instruction program designed to promote increased learning for Spanish speaking DLL in language, literacy, and math. The DLL in the randomized Preparing Pequeños intervention classrooms were compared to control DLL with comparable Spanish language delays and in which the school district's core curriculum was being implemented.

An intrinsic feature of the developing brain is high susceptibility to environmental influence-known as plasticity. Research indicates cascading disruption to neurological development following preterm (PT) birth; yet, the interactive effects of PT birth and plasticity remain unclear. It is possible that, with regard to neuropsychological outcomes in the PT population, plasticity is a double-edged sword.

Technology advances increasingly allow for access to remotely delivered interventions designed to promote early parenting practices that protect against child maltreatment. Among low-income families, at somewhat elevated risk for child maltreatment, there is some evidence that parents do engage in and benefit from remote-coaching interventions. However, little is known about the effectiveness of such programs to engage and benefit families at high risk for child maltreatment due to multiple stressors associated with poverty.

Article Synopsis
  • Caregiver responsiveness is linked to better early executive function (EF) development in children.
  • This study focused on how an intervention aimed at enhancing family child care providers' responsiveness affects children's EF.
  • Results showed that while the overall intervention did not significantly improve EF for all children, younger participants (aged 2.5 to 3.5) showed improvements in delay inhibition and attention problems when they received the intervention compared to older children.

Objective: Math and attention are related in neurobiological and behavioral models of mathematical cognition. This study employed model-driven assessments of attention and math in children with spina bifida myelomeningocele (SBM), who have known math difficulties and specific attentional deficits, to more directly examine putative relations between attention and mathematical processing. The relation of other domain general abilities and math was also investigated.

Article Synopsis
  • Longitudinal studies examine neurodevelopmental disorders diagnosed at birth, focusing on learning difficulties that emerge later, particularly in children with spina bifida myelomeningocele (SBM) who struggle with math but excel in reading.
  • Cognitive abilities assessed at ages 36 and 60 months were found to impact math and reading outcomes at ages 8.5 and 9.5, with visual-spatial working memory and phonological awareness acting as mediators for math skills, while phonological awareness alone influenced reading fluency and comprehension.
  • The results contribute to understanding the cognitive factors behind math and reading development and highlight both shared and unique aspects of these skills in children with SBM compared to their typically developing peers.

Despite reports of positive effects of high-quality child care, few experimental studies have examined the process of improving low-quality center-based care for toddler-age children. In this article, we report intervention effects on child care teachers' behaviors and children's social, emotional, behavioral, early literacy, language, and math outcomes as well as the teacher-child relationship. The intervention targeted the use of a set of responsive teacher practices, derived from attachment and sociocultural theories, and a comprehensive curriculum.

Objective: The current study examined the role of early executive functions (EF) and social language (SL) as well as responsive parenting as mediators of the effect of group on social problem-solving skills at 7 years of age for children with spina bifida and typically developing children.

Method: A mediation analysis was used to determine if the effect of having spina bifida on school age social problem-solving skills was mediated through the effect of group on EF/SL at 3 years of age and responsive parenting at 12 and 18 months. As part of a larger longitudinal study, 103 infants (n = 49 with spina bifida; n = 54 typically developing) received measures of EF/SL at 3 years of age and mother-infant play interactions at 12 and 18 months of age were coded for a range of responsive parenting behaviors.

Article Synopsis
  • Children with spina bifida myelomeningocele (SBM) often show good decoding skills but struggle with comprehension compared to their peers.
  • The study aimed to investigate the cognitive roots of bridging inferences and how these relate to reading comprehension in children with SBM.
  • Results indicated that certain preschool cognitive abilities (like working memory and oral comprehension) help explain the link between SBM and difficulties in making bridging inferences, which in turn affects reading comprehension.

Article Synopsis
  • The study compared infants with Spina Bifida (SB) to typically developing (TD) infants at 6 months of age to assess their learning and retention of a sensory-motor task.
  • While both groups showed increased arm-waving in response to the task, fewer infants with SB learned the motor contingency compared to TD infants, with variations in learning rates based on the evaluation criteria.
  • Infants with SB also struggled to retain the learned motor response over time, especially when sensory feedback was not present, indicating challenges in learning and motor response maintenance for infants with SB.

This study examined mother-child shared book reading behaviors before and after participation in a random-assignment responsive parenting intervention called Play and Learning Strategies (PALS) that occurred during infancy (PALS I), the toddler-preschool (PALS II) period, or both as compared with a developmental assessment (DAS) intervention (DAS I and/or II). The efficacy of PALS was previously demonstrated for improving mother and child behaviors within play contexts, everyday activities, and standardized measures of child language. We hypothesized that PALS effects would generalize to influence maternal and child behaviors during a shared reading task even though this situation was not a specific focus of the intervention and that this would be similar for children who varied in biological risk.
