Question

current attempt in progress
you occasionally receive your paycheck at the end of the month, although there are times when you receive it at the beginning of the
month or during the middle of the month. this is an example of which type of reinforcement schedule?
o fixed ratio
o fixed interval
o variable ratio
o variable interval

Explanation:

• Fixed ratio: Reinforcement after a fixed number of responses. Not relevant here as it's about time (month - related) not number of responses.
• Fixed interval: Reinforcement after a fixed time period. But here the time (end, beginning, middle of month) is not fixed.
• Variable ratio: Reinforcement after a variable number of responses. Again, not about number of responses.
• Variable interval: Reinforcement after a variable time period. Since the paycheck is received at variable times (end, beginning, middle of month - variable time within a month), this fits.

Answer:

variable interval
