Term: Variable-interval schedule
Definition (Myers): in operant conditioning, a schedule of reinforcement that reinforces a response at unpredictable time intervals.1
Definition (alternative): The first response after a variable time interval is reinforced. 2
Contextual explanation: Giving a prize or punishment in undefined intervals. For instance you sometimes get punished for certain behavior, but sometimes you don't get punished for same behavior. The point is that you don't know the interval between the previous punishment and the following punishment.
