  BEHAVIOUR THERAPY  **Shaping** **Definition**: Shaping involves reinforcing behaviors that are successively closer to the approximations of the target behavior. **Example**: A nurse working with a patient who has schizophrenia might use shaping to help the patient maintain personal hygiene.

Next, they might reinforce the patient for turning on the faucet, then for washing their hands, and eventually for taking a full shower. Each small step towards the final behavior is reinforced until the patient is consistently engaging in the target behavior. **Flooding** **Definition**: Flooding involves exposing clients to fear-invoking objects or situations intensely and rapidly. **Example**: For a patient with severe agoraphobia (fear of open spaces), a nurse might accompany the patient to an open park and encourage them to stay there for an extended period. The nurse provides support and reassurance w...
