A fixed interval schedule is one where reinforcement is delivered after a certain amount of time has passed since the last reinforcement. In the case of an infant being fed every four hours, this is similar to a fixed interval schedule because the reinforcement (feeding) occurs after a fixed amount of time (four hours). This is different from a fixed ratio schedule (which would involve reinforcement after a fixed number of responses) or a variable schedule (which would involve unpredictable timing of reinforcement).
