This is an example of a variable-interval schedule, as the reinforcement (compliment) is given after an unpredictable amount of time (two weeks followed by a gap of a month). This schedule can be an effective way to maintain behavior, as the individual cannot predict when the reinforcement will occur and must continue to perform the behavior consistently.
