Background: While delays in cognitive development are detectable during early development in Down syndrome, the neuropsychological and biomedical underpinnings of cognitive skill acquisition in this population remain poorly understood. Method: To explore this issue, 38 infants with Down syndrome [mean chronological age = 9.65 months; SD = 3.64]…

The prevalence of refractive error and ocular disorders among infants and young children with severe behavioral problems and developmental disorders is not well defined, particularly in developing countries. We performed a retrospective review of ophthalmic examinations performed during a National Institutes of Health--funded cohort study of very…

Video self-modeling (VSM) uses a method called "feedforward" to provide children the opportunity to view themselves as they perform in a more advanced or appropriate manner than they do presently. Typically, this is accomplished through the careful editing of videos. Studies on VSM and social skills with children on the autism spectrum…

Interventions to enhance cognitive and executive function performance are essential for the child's performance in current and future occupations. Occupational therapy practitioners are critical members of early intervention, education, and healthcare teams. Practitioners are distinctly qualified to address cognitive functioning within the context…

Background: Whereas research has indicated that children with Down syndrome (DS) imitate demonstrated actions over short delays, it is presently unknown whether children with DS recall information over lengthy delays at levels comparable with typically developing (TD) children matched on developmental age. Method: In the present research, 10…

Background: A population sample of people with Down Syndrome, repeatedly studied since infancy, has now been followed up at the age of 45 years. The paper is intended to give an overview of their abilities, as represented by the results of psychological tests, over their life span to date. Methods: As at all previous occasions from age 30 onwards,…

A child's move from early intervention (EI) to special education preschool is considered to be a critical transition point for both the child and family. Family concerns during this process are heightened by changes in service delivery systems. Although much has been written about the transition from EI services, little is known about the parents'…

Qigong massage is an eastern form of massage that can be delivered by western parents to their children with appropriate training and support. It has been shown to improve developmental measures in young children with autism when given daily for five months. A recent trial evaluating its effect on motor development in young children with Down…

Children with autism achieve mirror self-recognition appropriate to developmental age, but are nonetheless reported to have problems in other aspects of a sense of self. We observed behaviour in the mirror in 12 pre-school children with autism, 13 pre-school children with Down syndrome (DS) and 13 typically developing (TD) toddlers. Reliable…

Background: Many measures of infants' early cognitive development, including the BSID-II (The Bayley Scales of Infant Development), mix together test items that assess a number of different developmental domains including language, attention, motor functioning and social abilities, and some items contribute to the assessment of more than one…
