Thyroid hormones are critical for normal brain development. This study examined autism spectrum disorders (ASD) and thyroid stimulating hormone (TSH) levels measured in mid-pregnancy maternal serum and infant blood after birth. Three groups of children born in Orange County, CA in 2000-2001 were identified: ASD (n = 78), developmental delay…

Autism spectrum disorder (ASD) is characterized by impaired social interaction and communication, restricted interests and repetitive behaviors. Fragile X E is associated with X-linked non-specific mild intellectual disability (ID) and with behavioral problems. Most of the known genetic causes of ASD are also causes of ID, implying that these two…

In this article, I reflect on how ways of reporting research as well as reviewing and commenting on submitted manuscripts could take new directions to promote progress in the discipline of developmental science. I argue for (a) attitudinal openness toward migratory impulses in relation to Stokes's quadrant model of science, (b) the…

In educational contexts there are few topics that receive as much attention from adults as children's behaviour that is seen as challenging. Challenging behaviour has been a topic in many disciplines, such as education, child psychiatry, psychology and special education. Along with the definition of challenging behaviour, we can read about social…

Within a systemic view of the ontological world, we can view the effects of choices, thoughts and behaviours. Using the Socratic method of inductive reasoning and illustrating the interrelatedness we have with others such as at-risk youth, and inviting new thoughts regarding commonly held societal views and beliefs regarding those relationships,…

There is good evidence that if a woman is depressed, anxious, or stressed while she is pregnant, then there is an increased risk that her child will have emotional, behavioral, or cognitive problems. Her own biology must cause these effects, but it is not known how. One important line of research suggests that the function of the placenta changes…

Early research on child development in Africa was dominated by expatriates and was primarily addressed to the topics of testing the cross-cultural validity of theories developed "in the West," and the search for universals. After a brief review of the outcome of that research, we propose two additional types of motivation that seem…

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…
