Nuray Akkaya; Bürge Kabukçu Basay; Özkan Urak; Ömer Basay; Füsun Sahin – Journal of Attention Disorders, 2025
Objective: The study aimed to investigate whether the fine motor skills measured by the Functional Dexterity Test (FDT) in ADHD children differ from healthy controls. The second aim was to assess the applicability of the FDT assessment method among ADHD children. Method: The FDT results as an objective assessment of hand skills were compared…

Roebuck, Hettie; Freigang, Claudia; Barry, Johanna G. – Journal of Speech, Language, and Hearing Research, 2016
Purpose: Continuous performance tasks (CPTs) are used to measure individual differences in sustained attention. Many different stimuli have been used as response targets without consideration of their impact on task performance. Here, we compared CPT performance in typically developing adults and children to assess the role of stimulus processing…

Friedman-Hill, Stacia R.; Wagman, Meryl R.; Gex, Saskia E.; Pine, Daniel S.; Leibenluft, Ellen; Ungerleider, Leslie G. – Cognition, 2010
In this study, we attempted to clarify whether distractibility in ADHD might arise from increased sensory-driven interference or from inefficient top-down control. We employed an attentional filtering paradigm in which discrimination difficulty and distractor salience (amount of image "graying") were parametrically manipulated. Increased…

Groom, Madeleine J.; Liddle, Elizabeth B.; Scerif, Gaia; Liddle, Peter F.; Batty, Martin J.; Liotti, Mario; Hollis, Chris P. – Journal of Child Psychology and Psychiatry, 2013
Background: Children with attention deficit hyperactivity disorder (ADHD) are characterised by developmentally inappropriate levels of hyperactivity, impulsivity and/or inattention and are particularly impaired when performing tasks that require a high level of cognitive control. Methylphenidate (MPH) and motivational incentives may help improve…

Hunt, Melissa G.; Momjian, Ani J.; Wong, Keri K. – Psychological Assessment, 2011
The Test of Variables of Attention (TOVA) is a continuous performance test (CPT) that assesses attention, impulsivity, and processing speed. CPTs are used in the assessment of attention-deficit/hyperactivity disorder (ADHD) in children, but more young adults are being assessed for ADHD as well. The TOVA norms are based on a standardization sample…

Dhar, Monica; Been, Pieter H.; Minderaa, Ruud B.; Althaus, Monika – Neuropsychologia, 2010
Twenty male adults with ADHD, 16 dyslexic adults, 15 comorbid adults, and 16 normal controls were compared on performance and underlying brain responses, during a cued Continuous Performance Test (O-X CPT), with the aim of discovering features of information processing differentiating between the groups. The study evaluated both cue- and…

Hwang, Shoou-Lian; Gau, Susan Shur-Fen; Hsu, Wen-Yau; Wu, Yu-Yu – Journal of Child Psychology and Psychiatry, 2010
Background: The underlying mechanism of time perception deficit in long time intervals in attention-deficit/hyperactivity disorder (ADHD) is still unclear. This study used the time reproduction dual task to explore the role of the attentional resource in time perception deficits among children and adolescents with ADHD. Methods: Participants…

Wiersema, Roeljan; Van Der Meere, Jaap; Roeyers, Herbert; Van, Coster, Rudy; Baeyens, Dieter – Journal of Child Psychology and Psychiatry, 2006
Background: It has been repeatedly found that performance of children with attention deficit hyperactivity disorder (ADHD) is more impaired when a long inter-stimulus interval (ISI) is used than when a short ISI is used. According to the cognitive-energetic model, this may reflect difficulty in remaining in an optimal motor activation state…
