Fixed-interval schedule: a schedule in which the first response after a fixed amt of time has passed since the previous reinforce was delivered produces another reinforcer. Variable-interval schedule: a schedule in which the first response after a variable amt of time has passed since the previous reinforce was delivered produces another reinforcer. Fixed-ratio schedule: a schedule in which a fixed # of responses since the delivery of the previous reinforce produces another reinforce. Variable-ratio schedule: a schedule in which a variable # of responses since the delivery of the previous reinforce produces another reinforce.
