As in other subfields of psychology, developmental science faces a long-standing problem of limited diversity in research participants. This issue especially raises concerns when researchers make unwarranted broad claims about their results, such as using generic language that implies that a finding is unvarying and applies across participants and…

In this extensively revised edition, Martha Ann Bell and her contributors synthesize the newest research on how cognitive and emotional processes influence each other in child development. Historically, research in child development has treated cognitive processes as separate and distinct from social-emotional processes. However, many of the…

With the explosive growth in time spent on YouTube by babies and toddlers, it's important to analyze what they're watching on YouTube. Indexes that evaluate the contents of YouTube channels for infants and toddlers have been developed, but since those were evaluation-based indexes of educators and parents, it is difficult to find out what content…

Research suggests that elements of the family environment may have significant associations with cognitive and language development outcomes. Less is known, however, about the family environment in peri-urban China, where rates of cognitive and language delay in children aged 0-3 years are as high as 51% and 54%, respectively. Using data collected…

Children typically learn by attending to other people. Autism traits may impact access to social stimuli fundamental to early learning, increasing children's likelihood of a learning disability. Recent reports have highlighted that Autistic children from minority backgrounds have a higher likelihood of co-occurring intellectual disability. This…

Mathematical thinking is a complex, multi-faceted process that has been described as messy and difficult but can also show growth and insights into conceptual understanding and knowing. This paper explores the application of Edward de Bono's practical thinking, in particular, the occurrence of porridge words to examine the mathematical thinking of…

Research Findings: In the context of parent-child book sharing, cultural influences on cognitive distancing language and associations with child executive function (EF) have been understudied. This study examined cultural group similarities/differences in parent and child book-sharing distancing language among preschool-aged dual language learners…

Multilingual families face decisions about the linguistic upbringing of their children. These decisions shape their family language policy (FLP) which potentially impacts the children and their family. Departing from this hypothesis we conducted a systematic literature review applying the PRISMA guidelines, screening three databases, using search…

This article uses cognitive measures previously developed within linguistic relativity research to explore the thinking patterns of Yucatec Maya-Spanish bilingual children in the Yucatan peninsula. These measures were designed to detect cognitive patterns associated with specific language patterns. Here, these measures are used to test whether 12…

Shared intentionality theory posits that at age 3, children expand their conception of plural agency to include 3- or more-person groups. We sought to determine whether this conceptual shift is detectable in children's pronoun use. We report the results of a series of Bayesian hierarchical generative models fitted to 479 English-speaking…

There is clear evidence that the COVID-19 pandemic had significant negative effects on the learning and development of school-age children in the United States, with disproportionate impacts on children from racially, ethnically, and socioeconomically marginalized groups. There is less consistent evidence on the extent to which the pandemic…

Background/rationale: There is clear evidence that the COVID-19 pandemic had significant negative effects on the learning and development of school-age children in the United States, with disproportionate impacts on children from racially, ethnically, and socioeconomically marginalized groups (Irwin et al., 2022). There is less consistent evidence…

When linguistic input contains inconsistent use of grammatical forms, children produce these forms more consistently, a process called "regularization." Deaf children learning American Sign Language from parents who are non-native users of the language regularize their parents' inconsistent usages. In studies of artificial languages…

This report examines the critical role of home visitors in supporting dual language development among Latino children, who represent a growing share of the U.S. population. Through surveys and interviews with home visitors, UnidosUS identified gaps in training and resources needed to effectively serve culturally and linguistically diverse…

In response to the increasing linguistic diversity in educational settings resulting from migration waves into the Global North, this study delves into the beliefs of secondary teachers regarding multilingualism within predominantly monolingual policy schools in Flanders, Belgium. Despite the recognized benefits of multilingual pedagogies,…
