Employees at Pak-N-Sav, a discount grocery chain, know that they have to stay on their toes at all times. Mr. and Mrs. Kessler, the company founders, have been known to put on disguises and make unannounced visits to stores to make sure the staff is treating customers politely. This is an example of

a variable interval schedule.

Explanation:

An employee can be defined as an individual who is employed by an employer of labor to perform specific tasks, duties or functions in an organization.

Basically, an employee is saddled with the responsibility of providing specific services to the organization or company where he is currently employed while being paid a certain amount of money hourly, daily, weekly, or monthly depending on the contractual agreement between the two parties (employer and employee).

Hence, while an employer may be the owner of a business firm or company, an employee is a subordinate employed to provide unwavering services to the employer while also, being professional and diligent at all times.

In this scenario, the company founders put on disguises and make unannounced visits to different stores so as to ensure that the staff is treating customers politely. Thus, this is an example of a variable interval schedule.

Operant conditioning can be defined as an associative learning process which involves reinforcing the strength of a behavior.

Schedule of reinforcement is the precise timing pattern or rules which presents or removes a reinforcer or punisher respectively, with respect to an operant behavior. There are four (4) main types of schedule of reinforcements and these includes;

I. Intermittent schedules.

II. Interval schedules.

III. Response-duration schedules.

IV. Ratio schedules.

Ratio schedules typically involves reinforcement after a specific number of correct responses only. It is divided into two (2) main categories and these are;

I. Fixed ratio (FR) schedules.

II. Variable interval (VI) schedules.

Under a variable interval (VI) schedule of reinforcement, the target behavior is reinforced on the average of a specified number of correct actions.

Under a variable ratio (VR) schedule of reinforcement, a target behavior is reinforced by an employer or person on the average of a specified number of correct actions by another.
