This best illustrates the impact of "delayed reinforcers" on behavior.Delayed Reinforcement is a period delay between the coveted reaction of a life form and the conveyance of prize. In operant conditioning a conditioned reaction is the coveted reaction that has been conditioned and inspires fortification. A case might be seen with somebody on a diet. In spite of the fact that they are watching what they eat and practicing the fortification for their conduct (getting more fit) happens at a later time from the underlying work.
