Brief Summary
The proposed study is to test and validate a novel intervention that integrates computerized cognitive training with real-time neuromonitoring and neurofeedback to enhance working memory by probing the individualized neural systems underlying working memory. We will test the proposed intervention on children with ADHD with working memory deficits. The R61 proof-of-concept phase will assess the target engagement, effective dose and feasibility.

Outcome Measures
Primary Outcomes (2)
Change in Target Frontal-parietal Activity
Change in activity in the target frontal-parietal network measured by functional near infrared spectroscopy (fNIRS) during an N-back working memory task. A general linear model is applied to recorded signal and the beta coefficients from the model are extracted as a proxy for brain activity in fronto-pariteal network which subserves working memory function. There is no established population mean for beta coefficient of brain activity. Higher (lower) beta coefficients reflect higher (lower) activation in the target brain network. A positive change indicates increased brain activity. Increased frontal-parietal activity reflects better engagement of this brain network during working memory performance.
baseline and 6 weeks
Change in Working Memory Performance
Accuracy in an N-back working memory task was calculated as the percentage of correct responses to target stimuli.

Study Arms (3)
Neurofeedback
EXPERIMENTALThe Neurofeedback group will receive 12 sessions of computerized cognitive intervention combined with neurofeedback in the lab.
Cognitive Training
ACTIVE COMPARATORThe Cognitive Training group will receive 12 sessions of computerized cognitive intervention in the lab.
Waitlist
NO INTERVENTIONBoth Neurofeedback and Cognitive Training groups will be assigned to waitlist before starting the corresponding intervention.
Interventions
The Neurofeedback group will receive the proposed intervention which integrates computerized working memory training with neuromonitoring and neurofeedback.
The Cognitive training group will receive computerized working memory training with performance feedback.
