Martha leaves her used tea bags on the kitchen counter top, which leaves stains. To prevent ruining the counter top, she tries to remember to put her tea bags in the garbage instead. What reinforcement therapy is Martha using?

Negative Reinforcement

Explanation:

The type of reinforcement therapy that Martha is using is known as Negative Reinforcement. This is the case since Martha is performing the action of putting her tea bags in the garbage in order to take away a negative effect from occurring. This negative effect would be ruining the counter-top which would occur if she does not throw the tea bags in the garbage. This is known in psychology as a negative reinforcement since the negative possible outcome is reinforcing an individual to perform a specific action.
