Peer reviewed Peer reviewed

Gibbins, Christopher; Toplak, Maggie E.; Flora, David B.; Weiss, Margaret D.; Tannock, Rosemary – Journal of Attention Disorders, 2012
Objective: To examine factor structures of "Diagnostic and Statistical Manual of Mental Disorders" (4th ed.) symptoms of ADHD in adults. Method: Two sets of models were tested: (a) models with inattention and hyperactivity/impulsivity as separate but correlated latent constructs and (b) hierarchical general factor models with a general factor for…

Caterino, Linda C.; Verdi, Michael P. – Journal of Attention Disorders, 2012
Objective: The Kulhavy model for text learning using organized spatial displays proposes that learning will be increased when participants view visual images prior to related text. In contrast to previous studies, this study also included students who exhibited symptoms of ADHD. Method: Participants were presented with either a map-text or…

Objectively-Measured Impulsivity and Attention-Deficit/Hyperactivity Disorder (ADHD): Testing Competing Predictions from the Working Memory and Behavioral Inhibition Models of ADHD
Peer reviewed Peer reviewed

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)…

Severity of Children's ADHD Symptoms and Parenting Stress: A Multiple Mediation Model of Self-Regulation
Peer reviewed Peer reviewed
Direct linkDirect link
Graziano, Paulo A.; McNamara, Joseph P.; Geffken, Gary R.; Reid, Adam – Journal of Abnormal Child Psychology, 2011
The goal of the current study was to determine the extent to which the perceived self-regulation deficits across behavioral, cognitive, and emotional domains seen in children with ADHD explain the association between the severity of ADHD symptoms and parenting stress. Participants for this study included 80 children (mean age = 10 years, 9 months)…

Evidence for a General ADHD Factor from a Longitudinal General School Population Study
Peer reviewed Peer reviewed
Direct linkDirect link
Normand, Sebastien; Flora, David B.; Toplak, Maggie E.; Tannock, Rosemary – Journal of Abnormal Child Psychology, 2012
Recent factor analytic studies in Attention-Deficit/Hyperactivity Disorder (ADHD) have shown that hierarchical models provide a better fit of ADHD symptoms than correlated models. A hierarchical model includes a general ADHD factor and specific factors for inattention, and hyperactivity/impulsivity. The aim of this 12-month longitudinal study was…

Revisiting the Latent Structure of ADHD: Is There a "g" Factor?
Peer reviewed Peer reviewed
Direct linkDirect link
Martel, Michelle M.; von Eye, Alexander; Nigg, Joel T. – Journal of Child Psychology and Psychiatry, 2010
Background: Attention-deficit/hyperactivity disorder (ADHD) is presumed to be heterogeneous, but the best way to describe this heterogeneity remains unclear. Considerable evidence has accrued suggesting that inattention versus hyperactivity-impulsivity symptom domains predict distinct clinical outcomes and may have partially distinct etiological…

Deficient Attention Is Hard to Find: Applying the Perceptual Load Model of Selective Attention to Attention Deficit Hyperactivity Disorder Subtypes
Peer reviewed Peer reviewed
Direct linkDirect link
Huang-Pollock, Cynthia L.; Nigg, Joel T.; Carr, Thomas H. – Journal of Child Psychology and Psychiatry, 2005
Background: Whether selective attention is a primary deficit in childhood Attention Deficit Hyperactivity Disorder (ADHD) remains in active debate. Methods: We used the "perceptual load" paradigm to examine both early and late selective attention in children with the Primarily Inattentive (ADHD-I) and Combined subtypes (ADHD-C) of ADHD. Results:…
