Various arguments are reviewed about the claim that language development is critically connected to the development of theory of mind. The different theories of how language could help in this process of development are explored. A brief account is provided of the controversy over the capacities of infants to read others' false beliefs. Then the…

Researchers taking a domain-general approach to the development of scientific reasoning long thought that the ability to engage in scientific reasoning did not develop until adolescence. However, more recent studies have shown that preschool children already have a basic ability to evaluate evidence and a basic understanding of experimentation.…

Linear regression analysis is one of the most common techniques applied in developmental research, but only allows for an estimate of the average relations between the predictor(s) and the outcome. This study describes quantile regression, which provides estimates of the relations between the predictor(s) and outcome, but across multiple points of…

Infants' visual short-term memory (VSTM) for simple objects undergoes dramatic development: Six-month-old infants can store in VSTM information about only a simple object presented in isolation, whereas 8-month-old infants can store information about simple objects presented in multiple-item arrays. This study extended this work to examine…

This paper presents a set of strategies and options that California can use to leverage Medi-Cal, the State's Medicaid program, to move toward an equitable, advanced health delivery system for its children. Close to five million children are enrolled in Medi-Cal, more than two-thirds of whom are Black and Brown children. California's program alone…

COVID-19 was declared a pandemic by the World Health Organization and a public health emergency by the U.S. Centers for Disease Control in March 2020 (Centers for Disease Control and Prevention 2020). In the following months, families in the U.S. experienced financial hardships such as job and income loss, increasing food insecurity, and loss of…

To promote children's healthy development and give them opportunities to flourish, families need a wide range of support services. These services are often disconnected from each other. Early care and education (ECE) has a particularly fragmented system (National Academies of Sciences, Engineering, and Medicine 2018). Systems with myriad processes…

The Convention on the Rights of the Child and the Convention on the Rights of Persons with Disabilities (CRPD) emphasizes that all children have the right to be full members of society, and be included in all forms of participation inside the home and out in the community. Unfortunately, many children with disabilities are not afforded this…

The sharing of American Indian and Alaska Native (AIAN) cultures and lifeways provides opportunities for helping young children form deep connections to their community, which, in turn, aids in the development of their early language and literacy skills. This issue brief--based on interviews with eight Tribal Maternal, Infant, Early Childhood Home…

If school closures and social-distancing experiences during the COVID-19 pandemic impeded children's skill development, they may leave a lasting legacy in human capital. To understand the pandemic's effects on school children, this paper combines a review of the emerging international literature with new evidence from German longitudinal time-use…

School communities in both urban and rural settings need trauma-informed (TI) supports; however, the adversities experienced and access to student supports may be unique to rural school communities. In addition, the contextual challenges experienced by rural schools and communities, as well as the strengths that can be drawn from them, will…

Studying relationships in infant/toddler play, using visual narrative methodology to identify transitory moments, supports our current research on babies and toddlers. We use Vygotsky's theorisation of play to understand children's affective and intellectual aspirations in play. The theoretical discussion, using cultural-historical concepts,…

In this commentary, Suess opines that comparing risk- and non-risk-groups, as is done in the study by Witting, Ruiz, and Ahnert (2016), is a favored approach in developmental psychopathology in order to learn more about underlying mechanisms of normal development, as well as developmental deviations. Witting and colleagues followed up this…

This paper reports on the longitudinal links between first-time mothers (N = 48) Adult Attachment Interviews (AAIs), provided during pregnancy, and their first-born children's AAIs, provided at age 16 years. The AAIs from the adolescents were scored for reflective functioning (RF), and this was found to be significantly linked to whether their…

In this commentary, Spangler evaluates the Steele, Perez, Segal, and Steele report that arguede that reflective functioning in adolescence could not be predicted by quality of early infant attachment, but was associated with maternal (but not paternal) attachment representation, assessed before the adolescents' birth. Assuming that parental…
