What type of conditioning is this?

Question

Question: David has a substance abuse problem. He reports that while he does not experience euphoria from taking drugs, it removes the withdrawal symptoms when he does. He states that this leads to him continuing to seek and take drugs. What type of conditioning can explain this?

Positive Punishment, Negative Punishment, Positive Reinforcement, or Negative Reinforcement?

The answer I chose ended up being the polar opposite of what it was, so an explanation would be great for the answer, thank you.

Answer 1

Positive Reinforcement is adding something to a situation that makes the behavior more likely to occur, e.g., higher grades for studying more and asking good questions, you might study more and keep asking good questions.

negative reinforcement is removing something from a situation that makes something less likely to occur, e.g., having your headache go away when you take Tylenol, or having your withdrawal symptoms go away when you take a drug.
