Dataset Information

A neuroimaging dataset on working memory and reward processing in children with and without ADHD.

ABSTRACT: This article describes the public neuroimaging dataset entitled "Working Memory and Reward in Children with and without Attention Deficit Hyperactivity Disorder (ADHD)" available on OpenNeuro.org. This dataset uses functional magnetic resonance imaging (fMRI) while participants complete 8 n-back tasks designed to explore working memory, monetary reward, and feedback processing in typically developing children and children diagnosed with ADHD. In addition, this dataset includes longitudinal scores from a battery of standardized measures of cognitive ability, ADHD symptoms, and reading skill. Neuroimaging and standardized testing data were collected from 79 children, aged 8.6-12.0, of which 35 had a formal diagnosis of ADHD at session T1. 48 children returned two years later to complete standardized testing at session T2. Although some work has been published on the spatial working memory task, future research could investigate the verbal working memory and longitudinal data which are unexplored. In addition, this dataset is accompanied by an adult dataset, including 24 participants completing the same tasks entitled, "Working Memory and Reward in Adults" and available on OpenNeuro.org.

Project description:ObjectiveChildren with ADHD demonstrate impaired performance on a wide range of neuropsychological tests. It is unclear, however, whether ADHD is associated with many neurocognitive deficits or whether a small number of impairment(s) broadly influence test performance. The current study tests competing model predictions regarding two candidate causal mechanisms in ADHD: information processing speed and working memory.MethodA well-characterized sample of 86 children (Mage = 10.52, SDage = 1.54; 34 girls; 64% Caucasian/Non-Hispanic) with ADHD (n = 45) and without ADHD (n = 41) completed eight fully crossed experimental tasks that systematically manipulated working memory (BF?? = 1.80 × 10?³) and information processing speed (drift rate; BF?? = 7.61 × 10?).ResultsBayesian mixed-model ANOVAs indicated that increasing working memory demands produced significant reductions in information processing speed (drift rate; BF?? = 5.82 × 10??). In contrast, experimentally reducing children's information processing speed did not significantly change their working memory performance (BF?? = 1.31). ADHD status interacted with the working memory manipulation, such that the ADHD and non-ADHD groups showed equivalently high accuracy under the encoding-only conditions (BF?? = 3.45) but differed significantly under high working memory conditions (encoding + recall; BF?? = 19.58). Importantly, however, ADHD status failed to interact with (a) the working memory manipulation to differentially affect information processing speed and (b) the information processing speed manipulation to differentially affect working memory performance (all BF?? > 4.25).ConclusionsThese findings indicate that top-down executive control exerts significant effects on children's ability to quickly process information, but that working memory deficits and slowed information processing speed appear to be relatively independent impairments in ADHD.
