Del watches as his mother spins the wheels on his toy truck and then tries to repeat the behavior. When he attempts to do so, his mother smiles and nods at him. Researchers interested in operant conditioning would say that Del's mother has his behavior.

The correct answer is reinforced

In both cases, the goal is always to reinforce the behavior and increase the likelihood of it occurring again in the future. In real-world contexts, behaviors are unlikely to be reinforced each time they occur.

Behavior tends to repeat itself if reinforced and depends on learning.
