In psychology, a behavior therapy technique for eliminating nocturnal enuresis. When a child wets at night, an electric circuit is closed and a bell sounds, waking the child.
A psychological method of treating bed-wetting. When the child starts to pass urine it is detected by electric sensors in a pad (or by sheets of metallic mesh) and this sets off a bell (or loud buzzer), which wakens the child. He then empties his bladder fully. A process of conditioning leads to his learning to be dry. It is effective in about 80% of cases.
