Past research has focused on pretend play in infants with autism because it is considered an early manifestation of symbolic or imaginative thinking. Contradictory research findings have challenged the meta-representational model. The intent of this paper is to propose that pretend play is the behavioral manifestation of developing imaginative…

Authors examined 1,015 middle school students' knowledge of autism using a single item of prior awareness and a 10-item Knowledge of Autism (KOA) scale. The KOA scale was designed to assess students' knowledge of the course, etiology, and symptoms associated with autism. Less than half of students (46.1%) reported having heard of autism; however,…

Multiple dimensions of comprehensive treatment models (CTMs) for learners with autism were evaluated in this study. The purpose of the study was to provide evaluative information upon which service providers, family members, and researchers could make decisions about model adoption, selection for a family member, or future research. Thirty CTMs…

The present study investigated differences among children with three different patterns of autism symptom onset: regression, plateau, and no loss and no plateau. Cross-sectional data were collected from parents of children aged 3-17 years with an autism spectrum disorder (n = 2,720) who were recruited through a US-based online research database.…

This longitudinal study assessed multidisciplinary data on 219 children with autistic spectrum disorders from the median age of 5 (Time 1) to 8 years old (Time 2). The evolution of psychological and adaptive data was subjected to cluster analysis. Four clinically meaningful clusters emerged. The first group (21%) demonstrated the most important…

The study examined differences in the use of immediate echolalia by 18 children (ages 4-12) with autism at different stages of language development. Percentage of echolalic language was high at early stages of language development but decreased as language skills improved. (Author/DB)

We studied the association between an adult's behavior and episodes of social engagement (ESEs) in young children with autism during play-based assessment. ESEs were defined as events in which a child looked toward the adult's face and simultaneously showed an additional form of communicative behavior. The adult's behavior before each ESE, and…

This paper examines upper-body movement kinematics in individuals with high-functioning autism (HFA) and Asperger's disorder (AD). In general, the results indicate that HFA is more consistently associated with impaired motoric preparation/initiation than AD. The data further suggest that this quantitative difference in motor impairment is not…

Joint attention, a foundational nonverbal social-communicative milestone that fails to develop naturally in autism, was promoted for three toddlers with early-identified autism through a parent-mediated, developmentally grounded, researcher-guided intervention model. A multiple baseline design compared child performance across four phases of…

In this study we examined early motor, vocal, and communicative development in a group of younger siblings of children diagnosed with autism (Infant Siblings). Infant Siblings and no-risk comparison later-born infants were videotaped at home with a primary caregiver each month from 5 to 14 months, with follow-up at 18 months. As a group, Infant…

The use of the diagnosis "borderline" was evaluated with 16 children (6 to 13 years old) who were referred for comprehensive evaluation. None met DSM III criteria for borderline personality disorder. The borderline label had a negative impact on some children and was not helpful for treatment planning or disposition. (Author/SEW)

Data on 52 individuals with and 62 individuals without autism were analyzed to assess developmental aspects of the DSM-III-R (Diagnostic and Statistical Manual III, Revised) diagnostic system. Findings indicate that DSM-III-R criteria are more developmentally oriented and more behaviorally specific than previous criteria, but the diagnostic…

In 118 children followed from age 2 to 5 (59 with autism, 24 with PDD-NOS and 35 with non-spectrum developmental disabilities), age 2 and age 3 scores of non-verbal ability, receptive communication, expressive communication and socialization were compared as predictors of receptive and expressive language at age 5. Non-verbal cognitive ability at…
