B. F. Skinner was a psychologist, author, behaviorist and inventor of Operant conditioning chamber and Cumulative recorder. The purpose of cumulative recorder was to study the rate of operant conditioning. It is a process in which behavior of an organism is modified or an organism is conditioned to perform a specific behavior through giving punishment or reward.
For example: We teach a kid that he should not touch a hot stove because it will burn his hands, or we give him a box of candies to perform a specific task or behave in a certain way. Skinner used Cumulative recorder to find the effect of certain factors on behavior or response of an organism For example: the rate at which lever was pressed by a monkey to get bananas etc.
The correct answer is option B, that is, operant chamber.
Explanation:
B. F Skinner one of the American psychologists, that is, a behaviorist gave the theory of operant conditioning. According to which a behavior is predicted by its outcomes, that is, whether it is punishment or reinforcements that make it less or more probably for the behavior to take place.
Skinner invented the operant chamber in order to train subjects through operant conditioning. The operant chamber functions in an appropriate manner to view and record the rate of responses like a lever press or a key peck.
Plants take in that carbon dioxide<span> from the air, and take in water (H2O) as well. Photosynthesis produces a chemical reaction that creates glucose, or C6H12O6, out of CO2 and H2O.
