Answer:
Variable ratio
Explanation:
First, there are two different types of reinforcement:
<u>The positive reinforcement</u> applies a stimulus to increase the frequency of the desirable variable.
<u>The negative reinforcement</u> removes a stimulus to increase the frequency of the desirable variable.
However, the positive reinforcement divides itself in different types:
A <u>continuous reinforcemen</u>t schedule gives us a reinforcement every time we engaged in the desired conduct.
On the other side, the <u>partial reinforcement schedule</u> doesn't give us a reinforcement every time, but also divides itself in
And these divide themselves in fixed or variable.
- The fixed ratio schedule gives a reinforcement after a <u>fixed number </u>of desired responses.
- The variable ratio schedule gives a reinforcement after a <u>changing number</u> of desired responses.
- The fixed interval schedule gives a reinforcement after a <u>constant amount of time.</u>
- The variable interval schedule gives a reinforcement after a <u>variable amount of time.</u>
<u>So, in other words, ratio has to do with number of responses while interval has to do with amount of time. </u>

In the example, <u>you don't know</u> how many lottery tickets you must buy to get a winning ticket. But technically, <u>if you keep buying, you will get a winner one </u><u>(after an unknown number of attempts)</u>.
Therefore, buying scratch-lottery tickets is a reinforced according to a variable ratio schedule.
