Conditioned Learning

A bedwetting alarm works because of the principle of Conditioned Learning.

Conditioned Learning was discovered by Pavlov, a Russian psychologist in the early 1900s. He found that if a powerful stimulus is associated with a neutral one then after a time the neutral one acquires the same strength as the powerful one. In his work with dogs, Pavlov found that putting food in a dog’s mouth was a powerful stimulus triggering the production of saliva. He then experimented with ringing a bell each time he gave the dog some food and after a time he found that simply ringing a bell would result in the dog producing saliva. People are also affected by this kind of learning and mostly we are completely unaware that it is happening. Whenever a powerful and neutral stimulus occur together a link is made.

How a bedwetting alarm works

How a DRI Sleeper bed wetting alarm works.

In bed wetters the signal from the bladder that it is full is not registered by the brain during sleep. The alarm wakes the child as it starts to wet so it can feel the full bladder. Over time the child’s brain starts to recognise the feeling of a full bladder during sleep and will wake before the alarm triggers. 

Alarms have been proven to be the most effective method of treating bedwetting in children in 70%-90% of cases.
