Description of intervention(s) / exposure
During the state of nature (without any treatment or intervenes), 15 children with ADHD aged 11-16 years old, were asked to carry out a cued target detection task, in which participants were asked to respond to a white dot target, which could or could not be preceded by a star cue, during fMRI. The task lasted about 20 minutes.

Comparator / control treatment
During the state of nature (without any treatment or intervenes),15 normal controls, aged 11-16 years old, were asked to carry out a cued target detection task, in which participants were asked to respond to a white dot target, which could or could not be preceded by a star cue, during fMRI. The task lasted about 20 minutes.

Outcomes
Primary outcome [1] 2315 0
During this observational study, we measured the activation in frontal, parietal lobe and putamen during 20-minute alerting tasks in ADHD and normal control groups and compared the change of the blood oxygen level dependent (BOLD) signal in these areas between two groups.
Timepoint [1] 2315 0
Assessed in children with ADHD at baseline (without any treatment).
Secondary outcome [1] 4041 0
In this observational study, we measured the correlation of the ADHD symptoms severity for inattention and the change of the blood oxygen level dependent (BOLD) signal in the right precuneus in ADHD during 20-minute alerting tasks.
Timepoint [1] 4041 0
We assessed this outcome in children with ADHD at baseline (without any treatment).
