Sierra, María de los Dolores Valadez; Maldonado, Luis Alexis Aguiñaga; González, José Salvador Morales; Verche, Emilio; del Rosal, África Borges; Cervantes, Celia Josefina Rodríguez – Electronic Journal of Research in Educational Psychology, 2018
Introduction: Certain behaviors associated with high intellectual ability, such as inattention and early response, are often confused with attention deficit and hyperactivity disorder (ADHD), making correct diagnosis more difficult. The objective of the present study was to analyze the performance of students with high intellectual ability and…

Gopin, Chaya B.; Berwid, Olga; Marks, David J.; Mlodnicka, Agnieska; Halperin, Jeffrey M. – Journal of Attention Disorders, 2013
Objective: To examine the impact of reinforcement on reaction time (RT) and RT variability (RT standard deviation [RTSD]) in preschoolers with ADHD with and without oppositional defiant disorder (ODD), and a typically developing (TD) comparison group. Method: Participants were administered a computerized task consisting of two conditions: simple…

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…

Laasonen, Marja; Väre, Jenni; Oksanen-Hennah, Henna; Leppämäki, Sami; Tani, Pekka; Harno, Hanna; Hokkanen, Laura; Pothos, Emmanuel; Cleeremans, Axel – Annals of Dyslexia, 2014
In this study of the project DyAdd, implicit learning was investigated through two paradigms in adults (18-55 years) with dyslexia (n?=?36) or with attention deficit/hyperactivity disorder (ADHD, n?=?22) and in controls (n?=?35). In the serial reaction time (SRT) task, there were no group differences in learning. However, those with ADHD exhibited…

Karalunas, Sarah L.; Huang-Pollock, Cynthia L.; Nigg, Joel T. – Journal of Child Psychology and Psychiatry, 2013
Background: Intraindividual variability in reaction times (RT variability) has garnered increasing interest as an indicator of cognitive and neurobiological dysfunction in children with attention deficit hyperactivity disorder (ADHD). Recent theory and research has emphasized specific low-frequency patterns of RT variability. However, whether…

Nilsen, Elizabeth S.; Mangal, Leilani; MacDonald, Kristi – Journal of Speech, Language, and Hearing Research, 2013
Purpose: Successful communication requires that listeners accurately interpret the meaning of speakers' statements. The present work examined whether children with and without attention-deficit/hyperactivity disorder (ADHD) differ in their ability to interpret referential statements (i.e., phrasesthat denote objects or events) from speakers.…

van Mourik, Rosa; Sergeant, Joseph A.; Heslenfeld, Dirk; Konig, Claudia; Oosterlaan, Jaap – Journal of Child Psychology and Psychiatry, 2011
Background: Impaired cognitive control has been implicated as an important developmental pathway to attention deficit/hyperactivity disorder (ADHD). Cognitive control is crucial to suppress interference resulting from conflicting information and can be measured by Stroop-like tasks. This study was conducted to gain insight into conflict processing…

Sjowall, Douglas; Roth, Linda; Lindqvist, Sofia; Thorell, Lisa B. – Journal of Child Psychology and Psychiatry, 2013
Background: The notion that ADHD constitutes a heterogeneous disorder is well accepted. However, this study contributes with new important knowledge by examining independent effects of a large range of neuropsychological deficits. In addition, the study investigated whether deficits in emotional functioning constitute a dissociable component of…

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…

Adams, Zachary W.; Roberts, Walter M.; Milich, Richard; Fillmore, Mark T. – Psychological Assessment, 2011
Increased intraindividual variability in response time (RTSD) has been observed reliably in attention-deficit/hyperactivity disorder (ADHD) and has often been used as a measure of inattention. RTSD is assumed to reflect attentional lapses and distractibility, though evidence for the validity of this connection is lacking. We assessed whether RTSD…

Gilboa, Yafit; Rosenblum, Sara; Fattal-Valevski, Aviva; Toledano-Alhadef, Hagit; Rizzo, Albert; Josman, Naomi – Research in Developmental Disabilities: A Multidisciplinary Journal, 2011
The objectives of this study were to describe the nature of the attention deficits in children with Neurofibromatosis type 1 (NF1) in comparison with typically developing (TD) children, using the Virtual Classroom (VC), and to assess the utility of this instrument for detecting attention deficits. Twenty-nine NF1 children and 25 age-and…

Raiker, Joseph S.; Rapport, Mark D.; Kofler, Michael J.; Sarver, Dustin E. – Journal of Abnormal Child Psychology, 2012
Impulsivity is a hallmark of two of the three DSM-IV ADHD subtypes and is associated with myriad adverse outcomes. Limited research, however, is available concerning the mechanisms and processes that contribute to impulsive responding by children with ADHD. The current study tested predictions from two competing models of ADHD--working memory (WM)…

Kaufmann, Liane; Zieren, Nikola; Zotter, Sibylle; Karall, Daniela; Scholl-Burgi, Sabine; Haberlandt, Edda; Fimm, Bruno – Developmental Medicine & Child Neurology, 2010
Aim: The objective of this study was to investigate which attentional components are of predictive utility in differentiating children with attention-deficit-hyperactivity disorder, combined type (ADHD-C) from their peers without ADHD. Methods: Thirty-four children participated in the study: 17 males with ADHD-C (mean age 10y 4mo, SD 1y 9mo) and…

Lambek, Rikke; Tannock, Rosemary; Dalsgaard, Soeren; Trillingsgaard, Anegen; Damm, Dorte; Thomsen, Per Hove – Journal of Child Psychology and Psychiatry, 2010
Objective: The study investigates behavioural, academic, cognitive, and motivational aspects of functioning in school-age children with attention-deficit/hyperactivity disorder (ADHD) with and without an executive function deficit (EFD). Method: Children with ADHD - EFD (n = 22) and children with ADHD + EFD (n = 26) were compared on aspects of…

Christiansen, Hanna; Oades, Robert D. – Journal of Attention Disorders, 2010
Objective: Negative priming (NP) is the slowed response to a stimulus that was previously ignored. Response times in NP task conditions were compared with the interference provided by congruent/incongruent stimuli in a Stroop condition in the same task in children diagnosed with attention-deficit hyperactivity disorder (ADHD), their unaffected…
