Answer:
Variable Ratio Schedule
Explanation:
First, there are two different types of reinforcement:
The positive reinforcement applies a stimulus to increase the frequency of the desirable variable.
The negative reinforcement removes a stimulus to increase the frequency of the desirable variable.
However, the positive reinforcement divides itself in different types:
A continuous reinforcement schedule gives us a reinforcement every time we engaged in the desired conduct.
On the other side, the partial reinforcement schedule 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</u> <u>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>
In the example, the rats get a pellet of food, so we're talking about a reinforcement. They <u>don't get a reward EVERY TIME</u> they press the bar so we are not talking about a continuous reinforcement but a partial reinforcement. Since the rats press the bar and get a reward after certain <u>NUMBER</u> of times, we're talking about a ratio schedule. Finally, the number of times they need to press the bar to get a reward <u>VARIES</u> from trial to trial so this is a Variable Ratio Schedule.
Answer:
Option A
Explanation:
At the cellular level, the thyroid epithelia cells form follicles filled with colloid – includes materials needed for thyroid hormone production. These follicles range in size from 0.02-0.3mm and the epithelium may be simple cuboidal or simple columnar.
Yes because in the 1800's people still need to tranport themselfs to work or where they need to be and now we still do now
