Which of the following is an advantage of conducting psychological research in a laboratory?

a- it is easy to conduct laboratory research without subjects knowing that they are being observed.
b- a laboratory setting is close to the real world and therefore causes subjects to behave naturally.
c- it is possible to study all aspects of the mind and behavior in a laboratory.
d- a laboratory is a controlled setting with many of the potential confounding factors of the real world removed.

D- A laboratory is a controlled setting with many of the potential confounding factors of the real world removed.

Explanation:

D is true because if an experiment is conducted in the real world, then there is little control over any variable that can influence the behavior of the subject. However, in the lab, different variables, such as temperature, can be manipulated or controlled to observe specific behaviors in response to that variable.

A is not true, because humans have enough intuition to know if they are in a unusual environment. This makes it easy for humans to eventually realize they are being observed.

If B is true, then a laboratory is no better than a real-world or field setting.

C is not true because human technology to study and understand the human brain is limited. Because of this, there are limitations to what we can study about the mind and behavior.

replace   c   with   a   and simplify.
