Rogalski, Yvonne; Key-DeLyria, Sarah E.; Hazamy, Audrey; Altmann, Lori J. P. – Journal of Speech, Language, and Hearing Research, 2022
Purpose: This study compared global coherence (GC) in individuals with Parkinson's disease (PD) to a healthy older adult (HOA) group during single (sitting) and dual (stationary cycling) tasks. Additionally, it explored the relationship between GC and cognition in PD. Method: Thirty-seven individuals with PD and 19 HOAs participated in the…

Deng, Meiqi; Cai, Dan; Zhou, Xuan; Leung, Ada W. S. – Learning Disability Quarterly, 2022
The aim of the present study was to investigate the executive function and planning features of students with different types of learning difficulties. Students with mathematics difficulty (MD; n = 17), reading difficulty (RD; n = 12), and their commonalities (MDRD; n = 22), along with typically academically developing peers (TD; n = 22), were…

Fitzhugh, Megan C.; LaCroix, Arianna N.; Rogalsky, Corianne – Journal of Speech, Language, and Hearing Research, 2021
Purpose: Sentence comprehension deficits are common following a left hemisphere stroke and have primarily been investigated under optimal listening conditions. However, ample work in neurotypical controls indicates that background noise affects sentence comprehension and the cognitive resources it engages. The purpose of this study was to examine…

Reichelt, Amy C.; Killcross, Simon; Hambly, Luke D.; Morris, Margaret J.; Westbrook, R. Fred – Learning & Memory, 2015
In this study we sought to determine the effect of daily sucrose consumption in young rats on their subsequent performance in tasks that involve the prefrontal cortex and hippocampus. High levels of sugar consumption have been associated with the development of obesity, however less is known about how sugar consumption influences behavioral…

Silva, Katiane L.; Guimaraes-da-Silva, Paula O.; Grevet, Eugenio H.; Victor, Marcelo M.; Salgado, Carlos A. I.; Vitola, Eduardo S.; Mota, Nina R.; Fischer, Aline G.; Contini, Veronica; Picon, Felipe A.; Karam, Rafael G.; Belmonte-de-Abreu, Paulo; Rohde, Luis A.; Bau, Claiton H. D. – Journal of Attention Disorders, 2013
Objective: This study addresses if deficits in cognitive, attention, and inhibitory control performance in adults with ADHD are better explained by the disorder itself or by comorbid conditions. Method Adult patients with ADHD ("n" = 352) and controls ("n" = 94) were evaluated in the ADHD program of a tertiary hospital. The…

Weissman, Adam S.; Chu, Brian C.; Reddy, Linda A.; Mohlman, Jan – Journal of Clinical Child and Adolescent Psychology, 2012
Inattention is among the most commonly referred problems for school-aged youth. Research suggests distinct mechanisms may contribute to attention problems in youth with anxiety disorders versus youth with attention deficit hyperactivity disorder (ADHD). This study compared children (8-17 years) with anxiety disorders (n = 24) and children (8-16…

Sukhodolsky, Denis G.; Landeros-Weisenberger, Angeli; Scahill, Lawrence; Leckman, James F.; Schultz, Robert T. – Journal of the American Academy of Child & Adolescent Psychiatry, 2010
Objective: Neuropsychological functioning in children with Tourette syndrome (TS) has been characterized by subtle deficits in response inhibition, visual-motor integration, and fine-motor coordination. The association of these deficits with the tics of the TS versus co-occurring attention-deficit/hyperactivity disorder (ADHD) has not been well…

Motlagh, Maria G.; Sukhodolsky, Denis G.; Landeros-Weisenberger, Angeli; Katsovich, Liliya; Thompson, Nancy; Scahill, Lawrence; King, Robert A.; Peterson, Bradley S.; Schultz, Robert T.; Leckman, James F. – Journal of Attention Disorders, 2011
Objective: Exposure to heavy maternal cigarette smoking in pregnancy and severe maternal psychosocial stress during pregnancy appear to be important risk factors for the development of ADHD. This study aimed to determine whether these perinatal risk factors were associated with neuropsychological deficits commonly seen in ADHD. Method: We examined…

Samuelson, Kristin W.; Krueger, Casey E.; Wilson, Christina – Journal of Interpersonal Violence, 2012
Recently researchers have begun to explore the extent to which children's cognitive development is influenced by experiences in the family environment. Assessing mother-child dyads exposed to intimate partner violence (IPV), a population at risk for emotional and neurocognitive problems, we examined relationships between maternal emotional…

Hale, James B.; Reddy, Linda A.; Semrud-Clikeman, Margaret; Hain, Lisa A.; Whitaker, James; Morley, Jessica; Lawrence, Kyle; Smith, Alex; Jones, Nicole – Journal of Learning Disabilities, 2011
Methylphenidate (MPH) often ameliorates attention-deficit/hyperactivity disorder (ADHD) behavioral dysfunction according to "indirect" informant reports and rating scales. The standard of care behavioral MPH titration approach seldom includes "direct" neuropsychological or academic assessment data to determine treatment…

Mick, Eric; Byrne, Deirdre; Fried, Ronna; Monuteaux, Michael; Faraone, Stephen V.; Biederman, Joseph – Journal of Attention Disorders, 2011
Objective: The main aim of this study was to examine the age-dependent remission from ADHD in girls transitioning through childhood into adolescence and early adulthood. Method: We conducted a 5-year prospective follow-up study of 123 girls with ADHD and 106 non-ADHD control girls aged between 6 and 17 years at ascertainment. ADHD was considered…

Rodriguez-Aranda, Claudia; Sundet, Kjetil – Journal of Genetic Psychology, 2006
With 101 healthy aging adult participants, the authors investigated whether executive functions are a unitary concept. The authors established the factor structure of the Wisconsin Card Sorting Test (WCST; E. A. Berg, 1948), the Stroop color and word test (C. J. Golden, 1978), verbal fluency using the Controlled Oral Word Association Test (COWAT;…

Gualtieri, C. Thomas; Johnson, Lynda G. – Journal of Attention Disorders, 2006
Background: It has been proposed that ADHD is an executive control disorder. Little is known however about the maturation of executive control in ADHD. Method: A cross-sectional study of ADHD patients compared to normal controls tested on a computerized neurocognitive test battery. Participants: 175 patients with ADHD, age 10 to 29, compared to…
