Ankenman, Katy; Elgin, Jenna; Sullivan, Katherine; Vincent, Logan; Bernier, Raphael – American Journal on Intellectual and Developmental Disabilities, 2014
Research suggests that discrepant cognitive abilities are more common in children with autism spectrum disorder (ASD) and may indicate an important ASD endophenotype. The current study examined the frequency of IQ discrepancy profiles (nonverbal IQ greater than verbal IQ [NVIQ greater than VIQ], verbal IQ greater than nonverbal IQ [VIQ greater…

The present study addresses critical gaps in the literature by examining residential transitions among 303 adults with intellectual disability (ID) over 10 years (Part 1) and 75 adults with Down syndrome over 20 years (Part 2). All adults lived at home at the start of the study, but many moved to a variety of settings. Several characteristics of…

Labels are firmly rejected by the disability rights movement, yet the complex effects of labeling on lay beliefs are poorly understood. This study examined the effects of labeling on the general public's reactions to people with intellectual disabilities. A sample of 1,233 adult members of the UK general population were randomly presented with…

Perkins, Elizabeth A.; Berkman, Karen A. – American Journal on Intellectual and Developmental Disabilities, 2012
Research investigation of older adults with autism spectrum disorders (ASD) noticeably lags behind studies of children and younger adults with ASD. This article reviews the current literature regarding a range of quality of life outcomes of aging adults with ASD. Studies that have addressed life expectancy, comorbid physical and mental health…
