The Recipe 4 Success preventive intervention targeted multiple factors critical to the health and well-being of toddlers living in poverty. This randomized controlled trial, which was embedded within Early Head Start home visits for 12 weeks, included 242 racially and ethnically diverse families (51% girls; toddler mean age = 2.58 years; data…

This article examines the parent intervention program evaluated by Weber et al. (2017) and argues that there are scientific and ethical problems with such intervention efforts in applied developmental science. Scientifically, these programs rely on data from a small and narrow sample of the world's population; assume the existence of fixed…

This study investigated the longitudinal associations between children's early mathematics and their home numeracy environment (HNE). Chilean children from families who varied widely in socioeconomic status were assessed at the beginning and end of prekindergarten in 2016 (N = 419, M[subscript age] = 4:7 [years:months]), and at the end of…

Questioning is a core component of formal pedagogy. Parents commonly question children, but do they use questions to teach? This article defines "pedagogical questions" as questions for which the questioner already knows the answer and intended to help the questionee learn. Transcripts of parent-child conversations were collected from…

This study used Latent Class Analysis to identify groups of children exposed to similar Home Language and Literacy Environments (HLLE) and explored whether belonging to a given HLLE group was related to children's language and early literacy growth from prekindergarten to kindergarten. Participants were 1,425 Chilean mothers and their children…

The present article reports results of a real-world effectiveness trial conducted in Denmark with six thousand four hundred eighty-three 3- to 6-year-olds designed to improve children's language and preliteracy skills. Children in 144 child cares were assigned to a control condition or one of three planned variations of a 20-week storybook-based…

There is little evidence that infants learn from infant-oriented educational videos and television programming. This 4-week longitudinal experiment investigated 15-month-olds' (N = 92) ability to learn American Sign Language signs (e.g., patting head for hat) from at-home viewing of instructional video, either with or without parent support,…

Data from the Head Start Impact Study (N = 3,185, age = 3-4 years) were used to determine whether 1 year of Head Start differentially benefited children from homes with high, middle, and low levels of parental preacademic stimulation on three academic outcome domains--early math, early literacy, and receptive vocabulary. Results from residualized…

Examined European- and Hispanic-American mothers' multimodal communication to their 5- to 30-month-olds while they taught the children target words by using distinct objects during play. Found that mothers used target words more often than nontarget words in synchrony with object motion and sometimes touch, and tailored communication to infants'…

Examined early home literacy experiences, receptive language and emergent literacy skills, and reading achievement. Found that children's book exposure related to vocabulary development and listening comprehension, and that these skills related directly to grade 3 reading. Parents' literacy teaching related to early literacy skills, which…

Finds that preschool children remember lower case letters better if generally encouraged by their mothers to produce verbal responses and if their mothers have specifically taught lower case letters. Discusses three mechanisms that may explain this effect: mnemonic support for the child; membership in sociolinguistic group; and the teacher's being…

Examined cultural patterning in situational variability in mother-infant interactions among middle-class Anglo and Puerto Rican mothers and 12- to 15-month-old firstborns. Found that the emphasized socialization goals and childrearing strategies were consonant with individualistic orientations for Anglo mothers and sociocentric orientations for…

Objectives of this study were to examine effects of text genre (narrative and expository) and format (familiar and traditional) on teaching strategies mothers used when interacting with their children during reading tasks; and the effectiveness of mothers' teaching strategies in eliciting children's participation in joint reading tasks.
