A factory pays its employees on Wednesdays, and on Thursdays, employee productivity seems to be a little slow. The productivity gradually increases over the week and reaches its peak on Wednesday.
This is an example of which of the following types of schedules?

A. Variable interval
B. Variable ratio
C. Fixed interval
D. Fixed ratio

C. Fixed Interval

Explanation:

"Fixed Interval" is a type of Reinforcement Schedule. The "reward" in the situation above is the salary given to the employees during Wednesdays. As noticed, their productivity increases over the week, with the peak on Wednesday.  

The "peak" of productivity is the exhibited behavior during pay day. They try to work hard in order to receive a salary. They become more inspired to work during the salary day. It is followed by less productivity on Thursdays because they have already been rewarded.

Such reinforcement schedule is called the "fixed interval." This also means that their productivity will not increase if they will not be paid.

So, this explains the answer.
