Krasileva, Kate E.; Sanders, Stephan J.; Bal, Vanessa Hus – Journal of Autism and Developmental Disorders, 2017
This study assessed the utility of a brief assessment (the Peabody Picture Vocabulary Test-4th Edition; PPVT4) as a proxy for verbal IQ (VIQ) in large-scale studies of autism spectrum disorder (ASD). In a sample of 2,420 proband with ASD, PPVT4:IQ correlations were strong. PPVT4 scores were, on average, 5.46 points higher than VIQ; 79% of children…

Zantinge, Gemma; van Rijn, Sophie; Stockmann, Lex; Swaab, Hanna – Journal of Autism and Developmental Disorders, 2017
This study aimed to assess physiological arousal and behavioral regulation of emotion in the context of frustration in 29 children with Autism Spectrum Disorders (ASD) and 45 typically developing children (41-81 months). Heart rate was continuously measured and emotion strategies were coded, during a locked-box task. Results revealed increases in…

Terzi, Arhonto; Marinis, Theodoros; Francis, Kostantinos – Journal of Autism and Developmental Disorders, 2016
In order to study problems of individuals with Autism Spectrum Disorders (ASD) with morphosyntax, we investigated twenty high-functioning Greek-speaking children (mean age: 6;11) and twenty age- and language-matched typically developing children on environments that allow or forbid object clitics or their corresponding noun phrase. Children with…

Greenslade, Kathryn J.; Coggins, Truman E. – Journal of Autism and Developmental Disorders, 2016
This study presents an independent replication and extension of psychometric evidence supporting the "Theory of Mind Inventory" ("ToMI"). Parents of 20 children with ASD (4; 1-6; 7¬†years; months) and 20 with typical development (3; 1-6; 5), rated their child's theory of mind abilities in everyday situations. Other parent report…

Medeiros, Kristen; Winsler, Adam – Journal of Autism and Developmental Disorders, 2014
This study examined the relationship between child language skills and parent and child gestures of 58 youths with and without an autism spectrum disorder (ASD) diagnosis. Frequencies and rates of total gesture use as well as five categories of gestures (deictic, conventional, beat, iconic, and metaphoric) were reliably coded during the…

Kover, Sara T.; McDuffie, Andrea S.; Hagerman, Randi J.; Abbeduto, Leonard – Journal of Autism and Developmental Disorders, 2013
In light of evidence that receptive language may be a relative weakness for individuals with autism spectrum disorder (ASD), this study characterized receptive vocabulary profiles in boys with ASD using cross-sectional developmental trajectories relative to age, nonverbal cognition, and expressive vocabulary. Participants were 49 boys with ASD…

Goin-Kochel, Robin P.; Mazefsky, Carla A.; Riley, Brien P. – Journal of Autism and Developmental Disorders, 2008
Little evidence supports that siblings with autism exhibit the same behaviors; however, some findings suggest that level of functioning shows familial aggregation. We tested this notion among multiplex families participating with the Autism Genetic Resource Exchange (AGRE) Consortium, using scores on the "Peabody Picture Vocabulary Test-Third…

Mottron, Laurent – Journal of Autism and Developmental Disorders, 2004
A meta-analysis was performed on the 133 cognitive and behavioral papers in autism using comparison groups in the 1999-2002 period. High-functioning (average IQ: 84.7), adolescents (average, 14.4 years) are largely dominant. IQ is the most frequent matching variable in use (51.2%). The instruments that are most frequently used to determine IQ or…

Beck, Ann R.; Pirovano, Christine M. – Journal of Autism and Developmental Disorders, 1996
This study investigated the validity of using facilitated communication with individuals with autism (n=6) or profound cognitive impairments (n=6) on the Peabody Picture Vocabulary Test-Revised (PPVT-R) when facilitators were screened from visual and auditory stimuli. Results do not validate the use of facilitated communication with the PPVT-R or…
