功能性磁共振成像（fMRI）用于研究行为任务期间的大脑功能。儿科受试者的参与是有问题的，因为同时需要可靠的任务性能和头部运动的控制。差异强化减少头部运动和提高警觉性任务的表现在4名儿童（2行为障碍）进行模拟功能磁共振成像扫描。结果表明，行为分析技术可以提高儿童的合作过程中fMRID程序。
Functional magnetic resonance imaging (fMRI) is used to study brain function during behavioral tasks. The participation of pediatric subjects is problematic because reliable task performance and control of head movement are simultaneously required. Differential reinforcement decreased head motion and improved vigilance task performance in 4 children (2 with behavioral disorders) undergoing simulated fMRI scans. Results show that behavior analysis techniques can improve child cooperation during fMRId procedures.
