Final answer:
When parents believe children understand the rules and can act appropriately, they may use power assertion as a discipline strategy.
Step-by-step explanation:
When parents believe that children understand the rules they have violated and are capable of acting appropriately, they often prefer to use power assertion as a discipline strategy. Power assertion involves the use of punishment and authority to control a child's behavior. This can include actions such as yelling, spanking, or taking away privileges.
For example, if a child breaks a household rule, a parent using power assertion may yell at the child and take away their electronic devices as a consequence. The belief is that this form of discipline will help the child learn that their behavior is unacceptable and encourage them to make better choices in the future.
