The Neurofeedback group will receive 12 sessions of computerized cognitive intervention combined with neurofeedback in the lab.
The Neurofeedback group will receive the proposed intervention which integrates computerized working memory training with neuromonitoring and neurofeedback.
Active Comparator: Cognitive Training
The Cognitive Training group will receive 12 sessions of computerized cognitive intervention in the lab.
Behavioral: Cognitive training
The Cognitive training group will receive computerized working memory training with performance feedback.
No Intervention: Waitlist
Both Neurofeedback and Cognitive Training groups will be assigned to waitlist before starting the corresponding intervention.
- Change in target frontal-parietal activity [ Time Frame: baseline, 3 and 6 weeks ]Increased activity in the target frontal-parietal network measured by functional MRI (fMRI) and functional near infrared spectroscopy (fNIRS) during an N-back working memory task.
- Change in working memory performance [ Time Frame: baseline, 3 and 6 weeks ]Accuracy in an N-back working memory task.
- Change in Behavior Rating Inventory of Executive Function (BRIEF), Working Memory t-score [ Time Frame: baseline and 6 weeks ]BRIEF assesses everyday behavior associated with specific domains of the executive functions. BRIEF working memory t-score ranges from <30 to >100 with higher scores indicating larger impairment in working memory.
- Change in Wide Range Assessment of Memory and Learning 2 (WRAML-2), General Memory Index score [ Time Frame: baseline and 6 weeks ]WRAML-2 assesses clinical issues in learning and memory functions. WRAML-2 Working Memory Index score ranges from 50 to 150 with higher scores indicating better working memory performance
- Change in Conners 3rd Edition ADHD Index and Inattention t-score [ Time Frame: baseline and 6 weeks ]Conners 3 will be used to measure changes in clinical ADHD symptoms. Conners 3 ADHD index score ranges from 0 to 100 with higher scores indicating more ADHD symptoms. Inattention t-score ranges from <30 to >100 with higher scores indicating more inattention problems.
- Change in Developmental NEuroPSYchological Assessment II (NEPSY-II) composite score [ Time Frame: baseline and 6 weeks ]NEPSY-II consists of a set of subtests measuring cognitive functions required for success in school. The subtests include auditory attention & response, inhibition, word-list interference, and comprehension of instructions. The scaled scores on all subtests range from 0 to 20. The composite score will be quantified using principal component analysis on accuracy across these subtests.
- Change in Continuous Performance Test (CPT) accuracy [ Time Frame: baseline and 6 weeks ]CPT is standard test for measuring vigilance, sustained attention and inhibitory control.
- Change in California Verbal Learning Test - Children's version (CVLT-C) score [ Time Frame: baseline and 6 weeks ]CVLT-C test measures performance in learning and recalling verbal materials
- Change in Parent Stress Index 4th Edition (PSI-IV) [ Time Frame: baseline and 6 weeks ]PSI-IV evaluates the magnitude of stress in the parent-child system
