Purpose: The authors aimed to compare gesture use in infants with autism with gesture use in infants with other developmental disabilities (DD) or typical development (TD). Method: Children with autism (n = 43), DD (n = 30), and TD (n = 36) were recruited at ages 2 to 7 years. Parents provided home videotapes of children in infancy. Staff compiled…

The aim of this study is to describe the mathematical thinking process of autistic students in terms of gesture, using a qualitative approach. Data collecting is conducted by using 3 (three) audio-visual cameras. During the learning process, both teacher and students' activity are recorded using handy cam and digital camera (full HD capacity).…

Dyspraxia, a difficulty in executing an operationalised act, has been associated with Developmental Coordination Disorder (DCD). However, issues relating to the area such as comparisons across modalities, comparisons of school vs. clinical populations, and developmental delay vs. pathology have not been addressed in the same, comprehensive study.…

In this study, the relationship between gesture recognition and imitation was explored. Nineteen individuals with Autism Spectrum Disorder (ASD) were compared to a control group of 23 typically developing children on their ability to imitate and recognize three gesture types (transitive, intransitive, and pantomimes). The ASD group performed more…

Joint attention has long been considered absent or deviant in children with autism. Although this deficit is seen, there is variability in joint attention within the population and some children with autism employ it. Little is known about the profile of joint attention skills of these children or how joint attention use affects concurrent…

The number of children receiving cochlear implants (CIs) with significant disabilities in addition to their deafness has increased substantially. Unfortunately, children with additional disabilities receiving CIs have largely been excluded from studies on cochlear implant outcomes. Thus limited data exists on outcomes in this population to guide…

Purpose: Accurate description of an individual's communication status is critical in both research and practice. Describing the communication status of individuals with severe intellectual and developmental disabilities is difficult because these individuals often communicate with presymbolic means that may not be readily recognized. Our goal was…

Gaze avoidance is a hallmark behavioral feature of fragile X syndrome (FXS), but little is known about whether abnormalities in the visual processing of faces, including disrupted autonomic reactivity, may underlie this behavior. Eye tracking was used to record fixations and pupil diameter while adolescents and young adults with FXS and sex- and…

Previous studies indicate that Multiple Complex Developmental Disorder (MCDD) children differ from PDD-NOS and autistic children on a symptom level and on psychophysiological functioning. Children with MCDD (n = 21) and PDD-NOS (n = 62) were compared on two facets of social-cognitive functioning: identification of neutral faces and facial…

The hypothesis that young children with Williams syndrome show higher rates of emotional responsivity relative to other children with developmental disabilities was explored. Performance of 23 young children with Williams syndrome and 30 MA-matched children with developmental disabilities of nonspecific etiologies was compared on an adaptation of…

Twenty six children with autism, 24 children with developmental disabilities, and 15 typically developing children participated in tasks in which an adult displayed emotions. Child focus of attention, change in facial tone (i.e., hedonic tone), and latency to changes in tone were measured and summary scores of emotional contagion were created.…

The association between nonverbal requesting (as measured by the Early Social Communication Scales) and problem-solving skills (as measured by an object retrieval task) was examined in 16 toddlers who had Down syndrome, 18 toddlers with developmental disabilities of mixed etiologies, and 19 typically developing infants and toddlers. Toddlers with…

The joint attentional processes of 15 preschool children with autism and 15 preschool children with developmental language disorder were compared during play sessions with unfamiliar adults. It was found that the children with autism monitored the channel of communication with their adult play partners 37% less often than children in the…
