The following manuscript explores the application of family science theories to the field of child life. Ecological systems theory, family systems theory, and conflict theory will be presented and applied to child life. These theories explain the responsibilities and experiences of the specialist, their relationship with patients and families, and…

Experience-dependent change pervades early human development. Though trajectories of developmental change have been well charted in many domains, the episode-to-episode schedules of experiences on which they are hypothesized to depend have not. Here, we took up this issue in a domain known to be governed in part by early experiences: music. Using…

The study of how children learn numbers has yielded one of the most productive research programs in cognitive development, spanning empirical and computational methods, as well as nativist and empiricist philosophies. This paper provides a tutorial on how to think computationally about learning models in a domain like number, where learners take…

Deleuze and Guattari's thought on remainders of childhood has proven its worth for educational theory and philosophy. However, thus far the discussion has not paid much attention to their notion of infantilization, which reveals a new dimension of their understanding of childhood. In this article, I develop both their concept of becoming-child and…

The capacity for growth and development is an integral part of being human. Infant social-emotional development is critically important to overall development and begins in the first months of life. These processes encompass how we relate to ourselves and others in our everyday lives (Malti & Cheah, 2021). Social-emotional development includes…

Research on factors underlying socioeconomic status (SES)-related inequalities in child development mainly focuses on single countries and specific influential factors. Only few studies scrutinize to what extent differences in children's early behavioural outcomes vary across countries and whether the processes that account for them are common or…

Adverse health events within families can harm children's development, including their early literacy. Using data from a longitudinal Wisconsin birth cohort, we estimated the spillover effect of younger siblings' gestational ages on older siblings' kindergarten-level literacy. We sampled 20,014 sibling pairs born during 2007-2010 who took…

Across two studies, children ages 6-9 (N = 160, 82 boys, 78 girls; 75% White, 91% non-Hispanic) rated an inaccurate expert's knowledge and provided explanations for the expert's inaccurate statements. In Study 1, children's knowledge ratings decreased as he provided more inaccurate information. Ratings were predicted by age (i.e., older children…

The subjective number-space mapping and, especially, its evolution in young children has been the subject of intense controversy among different competing models. Many studies point out that: (i) young children's innate estimates follow a logarithmic mapping (Weber-Fechner law) and (ii) driven by education, children evolve into a linear mapping.…

The Early Childhood Commission (ECC) is an agency of the Ministry of Education and Youth in Jamaica responsible for early childhood development. It has been proposed that Early Childhood Practitioners (ECPs) should engage in more child friendly and age-appropriate teaching practices. This is especially critical as they use the Jamaica Early…

The authors contend that children benefit from play as a form of intervention and as a means of fostering their cognitive, social, and physical growth. They review several standardized instruments developed over the last fifty years to assess this benefit of play on child development. They identify twenty-one such play measures, the majority of…

Generative artificial intelligence (GAI) is rapidly becoming ubiquitous in many contexts. There is limited scholarship, however, in the fields of Developmental Psychology and Early Childhood Education exploring the implications of generative AI for babies and young children. In this Perspectives piece, we discuss potential use cases,…

Speech exhibits quasi-rhythmic regularities at multiple timescales, which seem to be crucial to comprehension. Both children's ability to extract rhythm from complex stimuli and to produce rhythmic patterns are known to undergo changes from infancy to adulthood. However, it remains unclear what rhythm skills specifically related to speech look…

Happiness is one of the most important parenting goals in today's modern society. To promote a happy childhood, we need to understand what happiness means to children. Contrary to the view that young children may equate happiness with satisfying material desires and experiencing simple pleasures, in this article, I review recent developmental…

Counterfactual emotions such as regret may aid future decision-making by encouraging people to focus on controllable features of personal past events. However, it remains unclear when children begin to preferentially focus on controllable features of such events. Across two studies, Australian 4-9-year-olds (N = 336, 168 females; data collected…
