Autism is often associated with early developmental delays in language and motor skills. However, little is known about the complex dynamic processes that drive the co-development of such early difficulties. The aim of the present study was to model the parallel growth of language and motor skills in a cohort of infants and to explore differences…

Purpose: The purpose of this study was to investigate the relationship of the grunt vocalizations to cognitive and expressive language status in children with disabilities. Children with typical development produce communicative grunts at the onset of referential word production and comprehension at 14-16 months of age and continue to use this…

Purpose: Chromosome 16p11.2 deletion syndrome (OMIM #611913) is a rare genetic condition resulting from the partial deletion of approximately 35 genes located at Chromosome 16. Affected people exhibit a variable clinical profile, featuring mild dysmorphisms, motor problems, developmental delay, mild intellectual disability (ID), socialization…

Background: Rubinstein-Taybi syndrome (RSTS) is a multiple congenital anomaly syndrome characterised by several typical somatic characteristics and by developmental disabilities with various degrees of severity. Focusing on children with RSTS, the aim of this study was to describe their psychomotor, cognitive, and socio-emotional developmental…

Purpose: Language is related to false-belief (FB) understanding in both typically developing children and children with autism spectrum disorder (ASD). The current study examined the role of complementation and general language in FB understanding. Of interest was whether language plays similar or different roles in the groups' FB performance.…

A retrospective review of initial early intervention and early childhood special education (EI/ECSE) evaluation reports was completed to identify practices specific to the evaluation of Latinx children's communication development. A records abstraction approach employed entailed a random selection of 294 EI/ECSE evaluation reports completed in…

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,…

A randomized control intervention study was conducted to evaluate the effects of the highly structured Heidelberg Parent-Based Language Intervention (HPLI). The outcomes of 43 children (n = 23 intervention, n = 20 control) who had been identified as late talkers during routine developmental check-ups carried out in pediatric practices at the age…

The present study examined narrative development in children and adolescents with Down syndrome longitudinally. Narratives were collected from 32 children and adolescents with Down syndrome three times over a 1-year period. Both micro- and macrolevel analyses were conducted. Significant growth over the 1-year period was seen in semantic complexity…

This study addressed two aims: First, to examine the quality of adult shared book-reading behaviors for teachers and caregivers of children with communication impairments (CI) and, second, to compare the level of child literacy engagement during the teacher-led (group) and caregiver-led (one-on-one) shared book-reading sessions. Sixteen children…

The potential effect of gender on intellectual abilities remains controversial. The purpose of this research was to analyze gender differences in cognitive test performance among children from continuous age groups. For this purpose, the normative data from 7 domains of the newly developed neuropsychological test battery, the Evaluacion…

Many educational Randomized Controlled Trials (RCTs) collect baseline versions of outcome measures (pretests) to be used in the estimation of impacts at posttest. Although pretest measures are not necessary for unbiased impact estimates in well executed experimental studies, using them increases the precision of impact estimates and reduces sample…

Two studies compared the descriptions given by children (N=74) with and without autism of animated stimuli depicting mechanical launching effects, intentional reactions, or sequences of mechanical and intentional reactions. Although children with autism were as able as control groups at these differentiations, differences were found in their…

Cross-cultural differences in emotional expressions following disappointment were examined in 59 Chinese American (CA) and 58 European American (EA) children. Children aged four or seven participated in a disappointing gift situation. Dimensions of expressive behaviors following disappointment were coded and included positive, negative, social…

Examined contributions of dimensions of maternal responsiveness to timing of milestones in early expressive language development. Found that maternal responsiveness at 9 and 13 months predicted timing of language milestones over and above children's observed behaviors. Responsiveness at 13 months was a stronger predictor of timing than…
