There are many different kinds of dolphin therapy. The simplest involve the child swimming with, touching or 'looking after' dolphins.
The more complex therapies, such as Dolphin-Assisted Therapy (DAT), are based on structured programmes which are supposedly designed to meet the needs of the individual child.
In DAT the child is encouraged to complete one or more pre-determined tasks, such as placing a ring on a peg or saying a word. If the child completes the task to a satisfactory standard, he or she is rewarded by being allowed to interact with a dolphin.
This interaction may include touching or kissing the dolphin, or getting into the water and taking a ride holding onto the dolphin's dorsal fin.
