Despite a robust literature examining the association between sleep problems and cognitive abilities in childhood, little is known about this association in toddlerhood, a period of rapid cognitive development. The present study examined the association between various sleep problems, using actigraphy, and performance on a standardized test of…

The relationship between turn taking (i.e., back-and-forth preverbal communicative exchanges) and joint attention has not been studied in interactions between children with autism and caregivers. In joint attention, a form of preverbal social communication, young children socially share attention with a partner about objects, a competency that is…

Real-time attention coordination in parent-toddler dyads is often studied in tightly controlled laboratory settings. These studies have demonstrated the importance of joint attention in scaffolding the development of attention and the types of dyadic behaviors that support early language learning. Little is known about how often these behaviors…

The current study examines teachers' differential emotion socialization practices with girls and boys by observing the emotion language of 27 teachers in naturally-occurring classroom interactions with 112 toddlers. This study explores the valence of teachers' emotion language, the type of teachers' emotion language, and the relation between…

The present study examined individual differences in the development of sustained attention across toddlerhood, as well as how these individual differences related to the development of language and sleep. Toddlers (N = 314; 54% male) were assessed at 30, 36, and 42 months using multiple measures of attention, a standardized language assessment,…

This study investigated responsive and directive speech from 60 Finnish mothers to their 2-year-old children, as well as correlations with concurrent and later vocabulary. Possible gender differences with regard to both maternal speech and children's vocabulary skills were considered. There were no gender differences in maternal utterance…

Supportive early relationships are critical to young children's development. Previous research has focused primarily on aspects of specific parenting practices that impact infants' and toddlers' development. However, additional research is needed for a more nuanced understanding of the relationships among family experiences, parenting behaviors,…

The purpose of this study is to investigate the relations among children's symbolic functioning at 15 months, joint attention at 24 months, expressive communication at 24 and 36 months, and executive functioning at 36 months. With the sample from rural areas in the United States collected by the Family Life Project (N = 1,008), a longitudinal data…

Aims: Although IDS is typically described as slower than adult-directed speech (ADS), potential impacts of slower speech on language development have not been examined. We explored whether IDS speech rates in 42 mother-infant dyads at four time periods predicted children's language outcomes at two years. Method: We correlated IDS speech rate with…

The relationship between turn taking (i.e., back-and-forth preverbal communicative exchanges) and joint attention has not been studied in interactions between children with autism and caregivers. In joint attention, a form of preverbal social communication, young children socially share attention with a partner about objects, a competency that is…

Developmental delays (DD) are missed early childhood developmental milestones in cognitive, motoric or linguistic domains. DD associated with behaviour problems may compound to impact parenting. This study investigated whether DD would moderate the relation between behaviour problems and parenting in families of toddlers. Data were drawn from an…

Research Findings: This study examined whether teacher-child interaction quality varied as a function of type of activity in toddler classrooms in four European countries (Finland, Netherlands, Poland, and Portugal). It also investigated whether specific activity settings, namely levels of adult involvement, use of whole group, and children's…

Communication is best understood as occurring along three dimensions: interactional, conceptual, and linguistic. However, few studies have examined early parent-child communication along all three dimensions simultaneously. This study examines these three dimensions of communication in Norwegian parent-child interactions during play. Thirty-nine…

Nonverbal turn taking, defined as back-and-forth exchanges, may be used to convey instrumental or social intent. It has been theorized that social turn taking is foundational to joint attention and, as such, it has been incorporated as a component of early interventions for children with autism, who often have challenges in joint attention…

Object word learning can be based on infant-related factors such as their manual actions and socio-linguistic factors such as parental input. Specific input for spatial features (i.e., size, shape, features of objects) can be related to object word comprehension in early vocabulary development. In a longitudinal study, we investigated whether fine…
