In the context of reinforcement theory, schedules in which the amount of time that must pass before a reward is given can change from one reward period to another are termed:

A) fixed interval schedules.
B) variable interval schedules.
C) fixed ratio schedules.
D) variable ratio schedules.

Variable Interval Schedules

Are interval schedules in which the amount of time that must pass before a reward is given can change from one reward period to another.

Fixed Ratio Schedules

Are ratio schedules in which the number of times a behavior must occur before it is rewarded remains constant over time.

Reinforcement Theory
