Children who are not motivated from within to participate in activities that are beneficial to them require items (reinforcers) that they are willing to work toward. This can be compared to any of us who do not feel motivated to do a particular job. If we are offered
enough money to do the job, we suddenly become willing to do whatever it takes to earn that money. Our children are much the same. Initially, they begin with a work-reward model and are reinforced with great frequency – generally after every expected response. As the child responds consistently to the frequent and immediate reinforcement, the goal should be to delay the reinforcement. The child learns to wait longer for that reinforcer while responding and accomplishing more.
