The variable interval schedule of reinforcement provides reinforcement after a varying amount of time. In this case, the time it takes for the toast to be ready varies, sometimes taking only ten seconds and other times taking several minutes. This type of schedule leads to consistent behavior because the individual does not know when the reinforcement will be delivered, encouraging them to continue engaging in the behavior.
