Developmental difference is a common characteristic of autism spectrum disorder (ASD) with unclear sex differences. The current study included 610 children with ASD, aged between 2 and 7 years, with completed language profiles. We used a nonparametric item response theory model called Mokken scale analysis to examine the order of acquisition of…

Previous research links resting frontal gamma power to key developmental outcomes in young neurotypical (NT) children and infants at risk for language impairment. However, it remains unclear whether gamma power is specifically associated with language or with more general cognitive abilities among young children diagnosed with autism spectrum…

This study investigated the contribution of fine and gross motor skills to academic and attentional performance at school entry among 832 boys and girls. Children were tested on their fine and gross motor skills (locomotor, object control) and their academic performance in receptive vocabulary, number knowledge, and attentional skills at 6 to 7…

Social mastery motivation and parental response are important correlates of children's vocabulary and self-regulation skills, but little research has examined their relationships collectively. This study investigated the direct relationships among social mastery motivation (active interaction and positive affect frequencies), parental response,…

The current 3-generation (N = 204 families), 3-year longitudinal study examined the intergenerational transmission of cultural socialization among Mexican-origin young mothers and their own mothers (i.e., children's grandmothers) and, in turn, whether young mothers' cultural socialization informed their children's developmental competencies (i.e.,…

The purpose of the current study is to determine the relationship between parental attitudes and children's receptive and expressive language skills. In the current study investigating the relationship between parental attitudes and children's expressive and receptive language skills, the relational survey model; one of the survey models, was…

Play is a powerful influence on children's learning and parents can provide opportunities to learn specific content by scaffolding children's play. Parent-child synchrony (i.e., harmony, reciprocity and responsiveness in interactions) is a component of parent-child interactions that is not well characterized in studies of play. We tested whether…

Parent-Child Interaction Therapy is an empirically based, behavioral parent training program for young children exhibiting disruptive behaviors. Parent--Child Interaction Therapy shows promise for treating disruptive behaviors in children with autism spectrum disorder. Treatment processes (i.e. treatment length and homework compliance), parenting…

The current study evaluated bidirectional associations between mother and father positive parenting and child effortful control. Data were drawn from 220 families when children were 3, 4, 5, and 6 years old. Parenting and effortful control were assessed when the child was 3, 4, and 5 years old. These variables were used to statistically predict…

Background: Children with language impairment (LI) show heterogeneity in development. We tracked children from pre-school to middle childhood to characterize three developmental trajectories: resolving, persisting and emerging LI. Methods: We analyzed data from children identified as having preschool LI, or being at family risk of dyslexia,…

We explored longitudinal effects of a two-generation preschool programme on receptive language scores in children (n = 78) at age 10 years, living with low income. Scores at four time-points, programme intake, exit, age 7, and age 10 years were measured using the "Peabody picture vocabulary test" (3rd ed.). Effects of culture…

Previous studies have demonstrated that various psychosocial risks are associated with poor cognitive functioning in children, and these risks frequently cluster together. In the current longitudinal study, we tested a model in which it was hypothesized that cumulative psychosocial adversity of mothers would have deleterious effects on children's…

Thirty-five children (17 boys and 18 girls, 4 to 8 years old) in 2-parent Chinese immigrant families had attended English-speaking facilities for 35.0 months (boys) and 32.9 months (girls), respectively. They were tested at home with the Peabody Picture Vocabulary Test-Revised (PPVT-R) and the Mandarin version of PPVT-R. No gender differences were…

Maternal education is a strong correlate of children's language, cognitive, and academic development. In most prior research, mothers' education has been treated as a fixed characteristic, yet many mothers, particularly economically and educationally disadvantaged mothers, attend school after the birth of their children. In the present study, we…
