The developing infant learns about the physical and the social world by engaging with objects and with people. In the study reported here, we investigated the relationship between infants' interactions with the physical and the social world. Three-month-old infants were trained for 2 weeks and experienced either actively manipulating objects…

U.S. schools teach predominately to the analytical, left-brain, which has foundations in behaviorism, and uses a mechanistic paradigm that influences epistemic beliefs of how learning takes place. This result is that learning is impeded. Using discourse analysis of a set of Piagetian children, this study re-analyzed Piaget's work. This study found…

Few studies exist of developmental trajectories in children with intellectual disability, and none for those with subtelomeric deletions. We compared developmental trajectories of children with Wolf-Hirschhorn syndrome to other genetic disorders. We recruited 106 children diagnosed with fragile X, Williams-Beuren syndrome, or Wolf-Hirschhorn…

Hobson (Autism and the development of mind. Lawrence Erlbaum, Hove, UK "1993") has proposed that the cognitive and linguistic disabilities that characterise autism result from abnormalities in inter-subjective engagement during infancy, which in turn results in impaired reflective self-awareness. The aim of the present study was to test Hobson's…

We used opposing figural aftereffects to investigate whether there are at least partially separable representations of upright and inverted faces in patients who missed early visual experience because of bilateral congenital cataracts (mean age at test 19.5 years). Visually normal adults and 10-year-olds were tested for comparison. Adults showed…

This study aimed to quantitatively characterize the main foot-ground contact parameters during static upright standing and to assess foot evolution with increasing age in young individuals affected by Down syndrome (DS). To this end, 99 children with DS of mean age 9.7 (1.7) were tested using a pressure sensitive mat, and the raw data were…

Children with autism spectrum disorders (ASD) present with a variety of comorbid difficulties, some of which relate to seemingly simply activities of daily living. Feeding and sleep difficulties are purportedly common within the ASD population, although the association between these problems and ASD symptomatology has rarely been addressed. The…

The age at which parents first developed concerns over their child's development was examined in 965 toddlers with autism spectrum disorders (ASD) and atypical development to examine the potential role of gender. A two-way analysis of covariance was conducted with gender and diagnosis entered as independent variables, age at assessment entered as…

Purpose: To evaluate joint engagement (JE) in age-matched children with and without hearing and its relationship to oral language skills. Method: Participants were 180 children with severe-to-profound hearing loss prior to cochlear implant surgery, and 96 age-matched children with normal hearing; all parents were hearing. JE was evaluated in a…

Evidence points to associations between the socioeconomic composition of neighborhoods and children's and adolescents' development. A minimal amount of research, however, examines how timing of exposure to neighborhood socioeconomic conditions matters. This study used longitudinal data from the NICHD Study of Early Child Care and Youth Development…

Many tests provide users with several different types of scores to facilitate interpretation and description of students' performance. Common examples include raw scores, age- and grade-equivalent scores, and standard scores. However, when used within the context of assessing growth among young children, these scores should not be interchangeable…

Although still a matter of some debate, there is a growing body of research supporting Early and Intensive Behavioral Intervention as the intervention of choice for children with autism. Learning rate is an alternative to change in standard scores as an outcome measure in studies of early intervention. Learning rates can be displayed graphically…

A randomized control study was conducted to evaluate Responsive Teaching (RT) with a sample of 15 Turkish preschool aged children with Down syndrome (DS) and their mothers over a six-month period of time. RT is an early intervention curriculum that attempts to promote children's development by encouraging parents to engage in highly responsive…

The purpose of this study is to analyze the ability of preschool children to take on a perspective, based on their self-perception and gender. A relational survey method was used, with 124 children between ages 5 and 6 participating--74 girls (59.7%) and 50 boys (40.3%). The Self-Perception Scale for Children and Perspective-Taking Test was…

Interest in the use of technology in the classroom continues to grow. The current study included 100 students who registered for a 200 level child development class at a private university in Northern Virginia. Students were from 4 different sections taught by the same professor in different semesters. Two of the sections used a textbook. The…
