How would the process of negative reinforcement encourage a person to use sunblock when heading to the beach?

What will be an ideal response?

A good answer would include the following key points:
- Negative reinforcement involves rewarding good behavior with the removal of something aversive.
- In this case, the good behavior is applying sunblock and the removal of something aversive is the risk of sunburn or skin cancer.
- If a person forgets or neglects to use sunblock, "punishment" will result in the form of a sunburn.
