Hendry, Alexandra; Jones, Emily J. H.; Bedford, Rachael; Andersson Konke, Linn; Begum Ali, Jannath; Bölte, Sven; Brocki, Karin C.; Demurie, Ellen; Johnson, Mark; Pijl, Mirjam K. J.; Roeyers, Herbert; Charman, Tony – Journal of Autism and Developmental Disorders, 2020
Autism is frequently associated with difficulties with top-down attentional control, which impact on individuals' mental health and quality of life. The developmental processes involved in these attentional difficulties are not well understood. Using a data-driven approach, 2 samples (N = 294 and 412) of infants at elevated and typical likelihood…

Domain-General and Domain-Specific Aspects of Temporal Discounting in Children with ADHD and Autism Spectrum Disorders (ASD): A Proof of Concept Study
Peer reviewed Peer reviewed
Direct linkDirect link
Demurie, Ellen; Roeyers, Herbert; Baeyens, Dieter; Sonuga-Barke, Edmund – Research in Developmental Disabilities: A Multidisciplinary Journal, 2013
It has been shown that delayed consumable rewards are discounted to a higher degree than money, which has been referred to as the "domain effect". Until now the effects of reward type on temporal discounting (TD) have mainly been studied in adults. Although there is evidence that children with attention-deficit/hyperactivity disorder (ADHD) tend…

Temporal Discounting of Monetary Rewards in Children and Adolescents with ADHD and Autism Spectrum Disorders
Peer reviewed Peer reviewed

Demurie, Ellen; Roeyers, Herbert; Baeyens, Dieter; Sonuga-Barke, Edmund – Developmental Science, 2012
It has been difficult to differentiate attention-deficit/hyperactivity disorder (ADHD) and autism spectrum disorder (ASD) in terms of some aspects of their cognitive profile. While both show deficits in executive functions, it has been suggested that they may differ in their response to monetary reward. For instance, children with ADHD prefer…

S.; Steinhausen, Hans-Christoph; Faraone, Stephen V.; Hartman, Catharina A.; Hoekstra, Pieter J. – Journal of the American Academy of Child & Adolescent Psychiatry, 2010
Objective: The genetic basis for autism spectrum disorder (ASD) symptoms in children with attention-deficit/hyperactivity disorder (ADHD) was addressed using a genome-wide linkage approach. Method: Participants of the International Multi-Center ADHD Genetics study comprising 1,143 probands with ADHD and 1,453 siblings were analyzed. The total and…

Empathic Accuracy in Adolescents with Autism Spectrum Disorders and Adolescents with Attention-Deficit/Hyperactivity Disorder
Peer reviewed Peer reviewed

Demurie, Ellen; De Corel, Maaike; Roeyers, Herbert – Research in Autism Spectrum Disorders, 2011
In research on theory of mind (ToM) in individuals with an autism spectrum disorder (ASD) mainly static mind-reading tasks were used. In this study both a static (Eyes Test) and a more naturalistic (empathic accuracy task) ToM measure were used to investigate the perspective taking abilities of adolescents with ASD (n = 13), adolescents with…

Common Alterations in Sensitivity to Type but Not Amount of Reward in ADHD and Autism Spectrum Disorders
Peer reviewed Peer reviewed
Direct linkDirect link
Demurie, Ellen; Roeyers, Herbert; Baeyens, Dieter; Sonuga-Barke, Edmund – Journal of Child Psychology and Psychiatry, 2011
Background: Children with attention deficit/hyperactivity disorder (ADHD) display abnormalities in reward processing. Most reward studies have focused on the effects of material or monetary rewards. Studies with autism spectrum disorder (ASD) have focused on social rewards. In this study we compared the effects of amount and type of reward in…

Effortful Control in Typically Developing Boys and in Boys with ADHD or Autism Spectrum Disorder
Peer reviewed Peer reviewed
Direct linkDirect link
Samyn, Vicky; Roeyers, Herbert; Bijttebier, Patricia – Research in Developmental Disabilities: A Multidisciplinary Journal, 2011
Despite increased interest in the role of effortful control (EC) in developmental disorders, few studies have focused on EC in autism spectrum disorders (ASD) and no study so far has directly compared children with ASD and children with ADHD. A first aim of this study was to investigate whether typically developing (TD) boys, boys with ADHD and…

Intra-Individual Variability in ADHD, Autism Spectrum Disorders and Tourette's Syndrome

Geurts, Hilde M.; Grasman, Raoul P. P. P.; Verte, Sylvie; Oosterlaan, Jaap; Roeyers, Herbert; van Kammen, Serena M.; Sergeant, Joseph A. – Neuropsychologia, 2008
The potential for response variability to serve as an endophenotype for attention deficit hyperactivity disorders (ADHD) rests, in part, upon the development of reliable and valid methods to decompose variability. This study investigated the specificity of intra-individual variability (IIV) in 53 children with ADHD by comparing them with 25…

Pragmatics Fragmented: The Factor Structure of the Dutch Children's Communication Checklist (CCC)
Peer reviewed Peer reviewed

Geurts, Hilde M.; Hartman, Catharina; Verte, Sylvie; Oosterlaan, Jaap; Roeyers, Herbert; Sergeant, Joseph A. – International Journal of Language & Communication Disorders, 2009
Background: A number of disorders are associated with pragmatic difficulties. Instruments that can make subdivisions within the larger construct of pragmatics could be important tools for disentangling profiles of pragmatic difficulty in different disorders. The deficits underlying the observed pragmatic difficulties may be different for different…

ADHD and Delay Aversion: The Influence of Non-Temporal Stimulation on Choice for Delayed Rewards
Peer reviewed Peer reviewed

Antrop, Inge; Stock, Pieter; Verte, Sylvie; Wiersema, Jan Roelt; Baeyens, Dieter; Roeyers, Herbert – Journal of Child Psychology and Psychiatry, 2006
Background: Delay aversion, the motivation to escape or avoid delay, results in preference for small immediate over large delayed rewards. Delay aversion has been proposed as one distinctive psychological process that may underlie the behavioural symptoms and cognitive deficits of attention deficit/hyperactivity disorder (ADHD). Furthermore, the…

Geurts, Hilde M.; Verte, Sylvie; Oosterlaan, Jaap; Roeyers, Herbert; Hartman, Catharina A.; Mulder, Erik J.; van Berckelaer-Onnes, Ina A.; Sergeant, Joseph A. – Journal of Child Psychology and Psychiatry, 2004
Background: The Children's Communication Checklist (CCC; Bishop, 1998) is a questionnaire that was developed to measure pragmatic language use and may be completed by parents and teachers. Two studies are reported, which were designed to investigate: (1) whether children with Attention Deficit Hyperactivity Disorder (ADHD) encounter pragmatic…
