Diamond has been expressing her anger by talking back to her teachers at school. White strategy would NOT be effective for Diamond's mother to take to reduce Diamond's negative behavior?

The correct answer is: Regular spankings given at home.

Explanation:

Corporal or physical punishment is not shown to have any long-term psychological benefits according to research.

It is more possible that physical punishment at an early age mixed with other contextual factors such as psychological abuse may lead to individuals developing psychopathologies later in life.

So, not only spanking would not correct a behavioral issue, it may even worsen it.

More effective strategies to reduce Diamond's negative behavior would be CBT, applying behavioral strategies such as negative and positive reinforcement, and so on.

In conclusion, to the question: strategy would NOT be effective for Diamond's mother to take to reduce Diamond's negative behavior? The correct answer is: Regular spankings given at home.
