Modification of activity level through biofeedback and operant conditioning.

Two kids wore a small box that beeped when their body moved too much or too little. Each beep gave them a point. Points bought candy and small toys.

The teacher could flip the box on or off. When it was on, the child had to move just the right amount to earn points. When it was off, no points were given.

Both kids changed their movement right away. The hyper child slowed down. The sluggish child sped up. When the box was turned off, the old movement came back.

Turning the box on again brought the new level back. The changes were large and happened in minutes.

Szempruch et al. (1993) later used the same idea to keep kids still during MRI scans. They replaced candy with praise and still avoided sedation. This shows the trick works in hospitals too.

Gardner et al. (1977) did it first with adults, teaching them to raise or lower blood pressure with tones. The 1978 study proves kids can do the same with movement.

Pan et al. (2016) used table-tennis to calm kids with ADHD. Their gains took twelve weeks. The 1978 biofeedback took one session. Both help ADHD, but speed differs.

You can plug a cheap motion beeper into any self-management plan. Let the learner pick the reinforcer and the target movement. Turn the box on for five minutes, off for five, then on again. The quick reversal shows the learner (and you) that the tool works. Use it before long meetings, tests, or transitions to set the right energy level fast.
