Intelligence (IQ) scores are used in educational and vocational planning for individuals with autism spectrum disorder (ASD) yet little is known about the stability of IQ throughout development. We examined longitudinal age-related IQ stability in 119 individuals with ASD (3-36 years of age at first visit) and 128 typically developing controls.…

In a non-selected sample of children with Neurofibromatosis type 1 (NF1) the prevalence rate of autism spectrum disorder (ASD) and predictive value of an observational (ADOS)--and questionnaire-based screening instrument were assessed. Complete data was available for 128 children. The prevalence rate for clinical ASD was 10.9%, which is clearly…

Levinson, Sarah; Neuspiel, Juliana; Eisenhower, Abbey; Blacher, Jan – Journal of Autism and Developmental Disorders, 2021
ASD symptomology and behavioral problems pose challenges for children with ASD in school. Disagreement between parents and teachers in ratings of children's behavior problems may provide clinically relevant information. We examined parent-teacher disagreement on ratings of behavior problems among children with ASD during the fall and spring of the…

Clark, Megan L. E.; Barbaro, Josephine; Dissanayake, Cheryl – Journal of Autism and Developmental Disorders, 2017
This paper charted the cognitive and behavioural profiles from toddlerhood to middle childhood in 48 children diagnosed with ASD at 24 months. The Mullen Scales of Early Learning (MSEL) was administered at 24- and 48-months and the Wechsler Abbreviated Scale of Intelligence (WASI) at school age. Autism severity was derived using The Autism…

Thorup, Emilia; Kleberg, Johan Lundin; Falck-Ytter, Terje – Journal of Autism and Developmental Disorders, 2017
This study tested whether including objects perceived as highly interesting by children with autism during a gaze following task would result in increased first fixation durations on the target objects. It has previously been found that autistic children differentiate less between an object another person attends to and unattended objects in terms…

Research on sex-related differences in Autism Spectrum Disorder (ASD) has been impeded by small samples. We pooled 28 datasets from 18 sites across nine European countries to examine sex differences in the ASD phenotype on the ADI-R (376 females, 1763 males) and ADOS (233 females, 1187 males). On the ADI-R, early childhood restricted and…

Eack, Shaun M.; Bahorik, Amber L.; Hogarty, Susan S.; Greenwald, Deborah P.; Litschge, Maralee Y.; Mazefsky, Carla A.; Minshew, Nancy J. – Journal of Autism and Developmental Disorders, 2013
Cognitive rehabilitation is an emerging set of potentially effective interventions for the treatment of autism spectrum disorder, yet the applicability of these approaches for "high functioning" adults who have normative levels of intelligence remains unexplored. This study examined the initial cognitive performance characteristics of 40…

Pijnacker, Judith; Vervloed, Mathijs P. J.; Steenbergen, Bert – Journal of Autism and Developmental Disorders, 2012
Children with congenital visual impairment have been reported to be delayed in theory of mind development. So far, research focused on first-order theory of mind, and included mainly blind children, whereas the majority of visually impaired children is not totally blind. The present study set out to explore whether children with a broader range of…

Kimhi, Yael; Bauminger-Zviely, Nirit – Journal of Autism and Developmental Disorders, 2012
Collaborative problem solving (CPS) requires sharing goals/attention and coordinating actions--all deficient in HFASD. Group differences were examined in CPS (HFASD/typical), with a friend versus with a non-friend. Participants included 28 HFASD and 30 typical children aged 3-6 years and their 58 friends and 58 non-friends. Groups were matched on…

Hollway, Jill A.; Aman, Michael G.; Butter, Eric – Journal of Autism and Developmental Disorders, 2013
We explored possible cognitive, behavioral, emotional, and physiological risk markers for sleep disturbance in children with autism spectrum disorders. Data from 1,583 children in the Autism Treatment Network were analyzed. Approximately 45 potential predictors were analyzed using hierarchical regression modeling. As medication could confound…

Ahmed, Fayeza S.; Miller, L. Stephen – Journal of Autism and Developmental Disorders, 2011
This study examined the relationship between Executive Function (EF) and Theory of Mind (ToM) using the Delis-Kaplan Executive Function System (D-KEFS) and three tests of ToM (Reading the Mind in the Eyes test (RMET), Strange Stories test, and Faux Pas test). Separate regression analyses were conducted, and EF predictors varied by ToM test. No EF…

Grinter, Emma J.; Van Beek, Pia L.; Maybery, Murray T.; Badcock, David R. – Journal of Autism and Developmental Disorders, 2009
Although there is good evidence that the behavioral traits of autism extend in lesser form to the general population, there has been limited investigation of whether cognitive features of the disorder also accompany these milder traits. This study investigated whether the superiority in visuospatial analysis established for individuals with autism…

Peer reviewedEagle, Rita Simon – Journal of Autism and Developmental Disorders, 1985
Five measures of intellectual level (IQ, MA, teachers' estimates of intelligence, level of object permanence, and representation of causality) were correlated with effectance variables and with each other for 42 quadraplegics (one to 12 years). Results reveal some relationship between intellectual level and effectance, although cognitive ability…

Peer reviewedEaves, Linda C.; Ho, Helena H. – Journal of Autism and Developmental Disorders, 1996
This study reports behavioral and cognitive stability and change in 76 children with autistic spectrum disorders, evaluated at ages 7 and 11. Verbal IQ, performance IQ, severity of autistic characteristics, and social characteristics were analyzed. The study found that IQ and more severe expression of autistic symptoms were very stable.

Peer reviewedGeiger, Diane M.; Smith, David T.; Creaghead, Nancy A. – Journal of Autism and Developmental Disorders, 2002
A study compared the extent of agreement between parents and professional evaluators regarding the cognitive level of 41 children (ages 2-10) with autism. Significant differences were found. In addition, there was significant correlation between the level of agreement and cognitive functioning; agreement increased as the level of cognitive…
