How would psychologists use the following processes to modify children’s undesirable behavior? • Schedules of reinforcement
• Extinction

Both are effective in removing undesirable behaviour.

Explanation:

Schedules of reinforcement are the rules that are used to remove a specific operant behavior. These rules are defined in terms of the time and the number of responses required in order to remove undesirable behaviour. Extinction is a procedure used in which reinforcement that is provided for problem behavior is discontinued in order to eliminate occurrences of different types of negative behaviors that are present in the children.
