A diffusion decision model analysis of the cognitive effects of neurofeedback for ADHD.

Objective: To examine cognitive effects of neurofeedback (NF) for attention-deficit hyperactivity disorder (ADHD) as a secondary outcome of a randomized clinical trial.

Method: In a double-blind randomized clinical trial (NCT02251743), 133 7-10-year olds with ADHD received either 38 sessions of NF ( = 78) or control treatment ( = 55) and performed an integrated visual and auditory continuous performance test at baseline, mid- and end-treatment. We used the diffusion decision model to decompose integrated visual and auditory continuous performance test performance at each assessment into cognitive components: efficiency of integrating stimulus information (), context sensitivity (), response cautiousness (), response bias (), and nondecision time for perceptual encoding and response execution ().
