A researcher records the time a child spends interacting with other children during recess at school for 3 days. To increase the time the child spends interacting with other children, he is given a reward for spending 2 added minutes interacting with other children, then a larger reward for 4 added minutes; and then a larger reward for spending 8 added minutes interacting with other children. The level of reward was changed only after the child met the interaction time required at the previous reward level. What type of single case design is described in this example?
