Answer:
Variable Ratio (VR)
Explanation:
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;
a. Fixed ratio (FR) schedules.
b. Variable ratio (VR) schedules.
Under a variable ratio (VR) schedule of reinforcement, the target behavior is reinforced on the average of a specified number of correct responses.
One of the most common example of variable ratio (VR) schedule of reinforcement is gambling and lottery games.
