TLDR
The finding that exposure to poverty in early childhood materially impacts brain development at school age further underscores the importance of attention to the well-established deleterious effects of poverty on child development.Abstract:Â
DESIGN, SETTING, AND PARTICIPANTS This study was conducted at an academic research unit at the Washington University School of Medicine in St Louis. Data from a prospective longitudinal study of emotion development in preschool children who participated in neuroimaging at school age were used to investigate the effects of poverty on brain development. Children were assessed annually for 3 to 6 years prior to the time of a magnetic resonance imaging scan, during which they were evaluated on psychosocial, behavioral, and other developmental dimensions. Preschoolers included in the study were 3 to 6 years of age and were recruited from primary care and day care sites in the St Louis metropolitan area; they were annually assessed behaviorally for 5 to 10 years. Healthy preschoolers and those with clinical symptoms of depression participated in neuroimaging at school age/early adolescence.read more

Socioeconomic and experiential influences on the neurobiology of language development
TL;DR: A specific focus is given to the burgeoning neuroimaging evidence of relationships between socioeconomic status (SES) and brain development, as well as to emerging research on proximal experiences that may serve as the direct mechanisms by which SES influences language development.

Poverty and Child Maltreatment
TL;DR: The authors reviewed current knowledge around child maltreatment and poverty and concluded that poverty is not only associated with maltreatment, but also a causal factor, and that any large gains in reducing maltreatment will come at least in part through socioeconomically oriented interventions or policies.

State-level macro-economic factors moderate the association of low income with brain structure and mental health in U.S. children
TL;DR: In this paper , the authors leveraged data from the Adolescent Brain and Cognitive Development (ABCD) study from 10,633 9-11 year old youth across 17 states and found that lower income was associated with smaller hippocampal volume and higher internalizing psychopathology.

A comparison of methods to test mediation and other intervening variable effects.
TL;DR: A Monte Carlo study compared 14 methods to test the statistical significance of the intervening variable effect and found two methods based on the distribution of the product and 2 difference-in-coefficients methods have the most accurate Type I error rates and greatest statistical power.
