Marie is using continuous reinforcement to teach her son to say thank you by praising him and hugging him every time he says it.
Continuous reinforcement is the repeated reinforcement of a behavior every time it happens. This can involve positive (adding a stimulus) or negative (removing a stimulus) reinforcement, with the goal of encouraging certain actions.
Continuous reinforcement is one of two foundational types of reinforcement schedules.
