Answer: positive reinforcement
Explanation:
Positive reinforcement when someone has done something good in order to encourage them further a particular positive stimulus is given to that person .
This introduced stimulus increases that behaviour in such that the person will be more likely to continue doing it all over again .
Most parents use this strategy to reinforce positive behaviour in their children as this intensifies the great behaviour that has already been started.
