Leyfer, Ovsanna; John, Angela E.; Woodruff-Borden, Janet; Mervis, Carolyn B. – Journal of Autism and Developmental Disorders, 2012
To examine the factor structure of temperament in 5-10-year-olds with Williams syndrome, an exploratory factor analysis was conducted on the responses of parents of 192 children on the children's behavior questionnaire. Four factors were identified. Two corresponded to factors reported for typically developing children: effortful control and…

Tye, Charlotte; Rijsdijk, Fruhling; Greven, Corina U.; Kuntsi, Jonna; Asherson, Philip; McLoughlin, Grainne – Journal of Child Psychology and Psychiatry, 2012
Background: Attention deficit hyperactivity disorder (ADHD) is a common and highly heritable neurodevelopmental disorder with a complex aetiology. The identification of candidate intermediate phenotypes that are both heritable and genetically linked to ADHD may facilitate the detection of susceptibility genes and elucidate aetiological pathways.…

Erdodi, Laszlo; Lajiness-O'Neill, Renee; Schmitt, Thomas A. – Journal of Autism and Developmental Disorders, 2013
Visual and auditory verbal learning using a selective reminding format was studied in a mixed clinical sample of children with autism spectrum disorder (ASD) (n = 42), attention-deficit hyperactivity disorder (n = 83), velocardiofacial syndrome (n = 17) and neurotypicals (n = 38) using the Test of Memory and Learning to (1) more thoroughly…

Shashi, V.; Veerapandiyan, A.; Schoch, K.; Kwapil, T.; Keshavan, M.; Ip, E.; Hooper, S. – Journal of Intellectual Disability Research, 2012
Background: Although distinctive neuropsychological impairments have been delineated in children with chromosome 22q11 deletion syndrome (22q11DS), social skills and social cognition remain less well-characterised. Objective: To examine social skills and social cognition and their relationship with neuropsychological function/behaviour and…

Roohi, Jasmin; DeVincent, Carla J.; Hatchwell, Eli; Gadow, Kenneth D. – Journal of Autism and Developmental Disorders, 2009
The aim of the present study was to examine the association between a variable number tandem repeat (VNTR) functional polymorphism in the promoter region of the MAO-A gene and severity of ADHD and anxiety in boys with ASD. Parents and teachers completed a DSM-IV-referenced rating scale for 5- to 14-year-old boys with ASD (n = 43). Planned…

McLoughlin, Grainne; Albrecht, Bjoern; Banaschewski, Tobias; Rothenberger, Aribert; Brandeis, Daniel; Asherson, Philip; Kuntsi, Jonna – Neuropsychologia, 2009
Background: Attention deficit hyperactivity disorder (ADHD) is a common neurodevelopmental disorder that starts in childhood and frequently persists in adults. Electrophysiological studies in children with ADHD provide evidence for abnormal performance monitoring processes and familial association of these processes with ADHD. It is not yet known…

Nijmeijer, J. S.; Hoekstra, P. J.; Minderaa, R. B.; Buitelaar, J. K.; Altink, M. E.; Buschgens, C. J. M.; Fliers, E. A.; Rommelse, N. N. J.; Sergeant, J. A.; Hartman, C. A. – Journal of Abnormal Child Psychology, 2009
The aims of this study were to investigate whether subtle PDD symptoms in the context of ADHD are transmitted in families independent of ADHD, and whether PDD symptom familiality is influenced by gender and age. The sample consisted of 256 sibling pairs with at least one child with ADHD and 147 healthy controls, aged 5-19 years. Children who…

Gadow, Kenneth D.; DeVincent, Carla J.; Schneider, Jayne – Journal of Attention Disorders, 2009
Objective: Identification of differences among children with ADHD only, autism spectrum disorder (ASD)+ADHD, and chronic multiple tic disorder (CMTD)+ADHD may lead to better understanding of clinical phenotypes. Method: Children were evaluated using the parent- and teacher-completed questionnaires. Results: All three groups were highly similar in…

O'Brien, Justin; Tsermentseli, Stella; Cummins, Omar; Happe, Francesca; Heaton, Pamela; Spencer, Janine – Early Child Development and Care, 2009
In this article, we examine the extent to which children with autism and children with learning difficulties can be discriminated from their responses to different patterns of sensory stimuli. Using an adapted version of the Short Sensory Profile (SSP), sensory processing was compared in 34 children with autism to 33 children with typical…
