This study is a randomized controlled trial of a 12-week community-based group parenting intervention ("CASITA") in Lima, Peru. CASITA improved neurodevelopment in a pilot study of 60 Peruvian children and subsequently scaled to 3,000 households throughout the district. The objective of this study was to assess intervention effectiveness…

This study takes an ecological approach to examine how children with developmental language disorder (DLD) interact with their classmates within early childhood special education (ECSE) inclusive classrooms. Participants were 124 children with DLD, 56 children with other disabilities, and 247 typically developing children (M[subscript…

Deficits in numerical magnitude perception characterize the mathematics learning disability developmental dyscalculia (DD), but recent studies suggest the relation stems from inhibitory control demands from incongruent visual cues in the nonsymbolic number comparison task. This study investigated the relation among magnitude perception during…

The causal role of speed of processing (SOP) in developmental language disorder (DLD) is unclear given that SOP has been implicated in other neurodevelopmental disorders such as attention-deficit/hyperactivity disorder. This study investigated associations between SOP, language, and inattention/hyperactivity in a U.K. epidemiological cohort…

We followed children at family risk of dyslexia and children with preschool language difficulties from age 3½, comparing them with controls (N = 234). At age 8, children were classified as having dyslexia or Developmental Language Disorder (DLD) and compared at earlier time points with controls. Children with dyslexia have specific difficulties…

Tests the hypothesis that developmentally delayed children differ from normal children on tasks involving discernment of nuances, balancing competing stimuli, or acquiring and retaining selected information. Attention deployment behaviors in a free-play situation were examined for three groups: normally developing, Down syndrome, and…

This study examined developmental outcome at 1 and 2 years in relation to the presence and severity of neonatal intraventricular hemorrhage. Intraventricular hemorrhage related to Bayley mental and motor scores and neurologic ratings at 1 year but not at 2 years. Significant associations were found between the 1- and 2-year measures but not…

Autistic children's direction of hemispheric asymmetry in response to linguistic stimuli differed significantly from that of normal subjects, showing reversed but not necessarily reduced patterns. Autistic children with more advanced language abilities were more likely to exhibit a normal direction of hemispheric asymmetry. Implications are…

Comparing developmental education for parents, parent education in child management, and a control situation, this study assessed treatment effectiveness in motivating parents to participate in home programs for developmentally delayed infants. Results indicated the superiority of the developmental program in terms of parent participation and…

Aimed to determine to what degree newborns' auditory brainstem evoked responses (ABRs) predict delayed or impaired development during the first year. When 93 infants' ABRs were evaluated at three, six, and nine months, newborn ABR was moderately sensitive for detecting hearing impairment and more sensitive than other indicators in detecting…

Examines 24 mother/impaired infant dyads to study the quality of interaction using the Ainsworth-Wittig attachment paradigm. Measures of general development and degree of child impairment significantly differentiated "classifiability" of attachment in the Ainsworth scheme. Infants rated higher on a social responsiveness measure were more…

Investigates the influence of chronological age, mental age, and handicapping condition on mothers' interactions with their handicapped young children. A total of 111 handicapped children ranging in age from 3 to 36 months and their mothers participated. Infants' general functioning and handicapping conditions were related to maternal…

Used growth curve analysis to describe the development of 186 preschoolers with vision impairments. Found that mental retardation and developmental delay were associated with lower developmental ages and slower growth rates. Visual function of 20/800 or worse was associated with lower developmental ages and slower growth rates in personal-social…

Investigated interactions among 18 African American mother-infant pairs participating in an early intervention program for infants with developmental delays or at risk for developmental disabilities. The hypothesis that mothers would become less responsive to infants over time as a function of drug addiction, poverty, or serious developmental…
