Neurocognitive processes such as executive functioning (EF) may influence the development of speech-language skills in deaf children after cochlear implantation in ways that differ from normal-hearing, typically developing children. Conversely, spoken language abilities and experiences may also exert reciprocal effects on the development of EF.…

Stimulus overselectivity is widely accepted as a stimulus control abnormality in autism spectrum disorders and subsets of other populations. Previous research has demonstrated a link between both chronological and mental age and overselectivity in typical development. However, the age at which children are developmentally ready to respond to…

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…

Existing literature shows promising effects of physical activity on children's cognitive outcomes. This study assessed via a randomized, controlled design whether additional curricular physical activity during the school day resulted in gains for children's fluid intelligence and standardized achievement outcomes. Participants were children…

Use of multivariate analysis (e.g., multivariate analysis of variance) is common when normally distributed outcomes are collected in intervention research. However, when mixed responses--a set of normal and binary outcomes--are collected, standard multivariate analyses are no longer suitable. While mixed responses are often obtained in…

Six-month-olds reliably discriminate different monkey and human faces whereas 9-month-olds only discriminate different human faces. It is often falsely assumed that perceptual narrowing reflects a permanent change in perceptual abilities. In 3 experiments, ninety-six 12-month-olds' discrimination of unfamiliar monkey faces was examined. Following…

Background: It is unclear why children with autism spectrum disorders (ASD) tend to be inattentive to, or even avoid eye contact. The goal of this study was to investigate affective-motivational brain responses to direct gaze in children with ASD. To this end, we combined two measurements: skin conductance responses (SCR), a robust arousal…

Background: Deficit in motor performance is common in children with intellectual disabilities (ID). A motor function measure with sound psychometric properties is indispensable for clinical and research use. The purpose of this study was to compare the psychometric properties of three commonly used clinical measures for assessing motor function in…

Spatial cognition and memory are critical cognitive skills underlying foraging behaviors for all primates. While the emergence of these skills has been the focus of much research on human children, little is known about ontogenetic patterns shaping spatial cognition in other species. Comparative developmental studies of nonhuman apes can…

Linguistic labels affect inductive generalization; however, the mechanism underlying these effects remains unclear. According to one similarity-based model, SINC (similarity, induction, naming, and categorization), early in development labels are features of objects contributing to the overall similarity of compared entities, with early induction…

This comparative study explores the verbal communication between museum educators and young children, based on principles of developmental psychology. In early developmental stages, when student learning is greatly dependent on verbal communications from the teacher, observation skills may be developed through purposeful instruction. Through the…

The question of whether understanding pretend play requires meta-representational skill was examined among typically developing children and individuals with autism. Participants were presented with closely equated true and false pretence trials in which they had to judge a protagonist's pretend reading of a situation, which either matched or…

This study utilized latent growth-curve analyses to determine if the early literacy skills of children who were Spanish-speaking language-minority (LM) followed a similar quantitative growth profile over a preschool year as that of a group of children from a comparable socioeconomic (SES) background but who were not LM. Participants, who ranged in…

Receptive language skills allow students to understand the meaning of words spoken to them. When students are unable to comprehend the majority of the words that are spoken to them, they do not have the ability to act on those words, follow given directions, build on prior knowledge, or construct adequate meaning. The inability to understand the…

Parent and child joint book reading (JBR) characteristics and parent facilitative language techniques (FLTs) were investigated in two groups of parents and their young children; children with normal hearing (NH; "n" = 60) and children with hearing loss (HL; "n" = 45). Parent-child dyads were videotaped during JBR interactions,…
