The purpose of this study was to examine the longitudinal, bidirectional relationship between language skills and behavior problems in a sample of 194 preschool children enrolled in Head Start programs. Children were individually assessed using the "Preschool Language Scale-5," and teachers completed the "Child Behavior…

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,…

Background and Purpose: Schoolchildren with language difficulties experience more peer victimization compared to their typically developing (TD) peers. Whether these children also bully their peers (bully perpetration) more than TD children is unclear. Furthermore, little is known about peer victimization and bully perpetration among preschool…

We examined the relations between language skills and behavior problems and whether social skills mediated these relations among preschool children enrolled in Head Start programs. Participants included 242 preschool children and their parents in Head Start programs. Over a 2-year period, parents and teachers reported children's behavior problems…

Poorer language ability has been shown to predict the development of externalizing behavior problems such as aggression and conduct problems. However, the developmental process that links poorer language ability to externalizing problems is unclear. The present study examined (a) whether within-child changes in language ability predict…

Language ability has been associated with emotion regulation (ER) ability. Children on the autism spectrum have greater rates of language delays and lower ER ability. Despite this, autism traits have not been considered or controlled for in past research. This study therefore examined the association between language ability and ER in young…

Research suggests that children with behavioural difficulties exhibit "positive illusory bias" (PIB), in which they overestimate their competencies leading to a perception of self that is more positive than the perceptions held by their peers, parents or teachers. However, research to date has focused on children of elementary school age…

Although early life experiences of language and parenting are critical for children's development, large home observation studies of both domains are scarce in the psychological literature, presumably because of their considerable costs to the participants and researchers. Here, we used digital audio-recorders to unobtrusively observe 107…

For individuals with autism spectrum disorder (ASD) daily living skills (DLS) fall below chronological age and have been linked to factors such as language. Given the impact of DLS on daily life, it is critical to gain a comprehensive understanding of DLS profiles in children to guide effective treatment. Using a large dataset from the Autism…

Based on 1,364 children across Grades 1, 3, and 5, the present study explored the mutualism of (externalizing and internalizing) behavioral problems and language, and whether social skills explained such mutualism. The random intercept cross-lagged panel models were conducted to control for between-person level variance and to explore mutualism of…

Purpose: Establishing stable and flexible phonological representations is a key component of language development and one which is thought to vary across children with neurodevelopmental disorders affecting language acquisition. Sleep is understood to support the learning and generalization of new phonological mappings in adults, but this remains…

Purpose: This study investigated the effects of enhanced milieu teaching (EMT) on caregiver implementation of language support strategies and child communication skills using a hybrid telepractice service delivery model. Method: Four caregivers and children with language delays aged 18-27 months participated in a multiple baseline across behaviors…

This study investigated the prevalence, and the developmental, behavior and emotional outcomes of 675 preschoolers with ASD with or without a history of regression, who participated in the Study to Explore Early Development (SEED). The SEED project is a cross-sectional case-control study that collected data between 2007 and 2011. Children's…

Purpose: The objective of this study was to compare children with persistent versus transient preschool language delay on language, academic, and psychosocial outcomes in elementary school. Method: Children with persistent language delay (n = 30), transient language delay (n = 29), and no language delay (controls; n = 163) were identified from a…

Learning to read two scripts at a young age is a demanding task. This study aims to develop games for building fundamental code-related emergent literacy skills among biscriptal preschoolers. We developed five games and tested them on a sample of 102 Chinese kindergarteners. The participants were aged 4 to 5 years and were learning English as a…
