Mark conducts a study for his research methods class to determine if consuming caffeine causes people to perform better on cogni
tive tasks. In his study, he gives half of his participants a glass of water and half of his participants a glass of cola, and then has them attempt to solve 15 math problems. He finds that people who drink caffeine beforehand solve more math problems than those who drink water beforehand. Mark decides to conduct a variation of the original study in which he measures participants' ability to solve verbal analogies as the cognitive task instead of measuring their ability to solve math problems. He finds that people who drink caffeine beforehand solve more verbal analogies than those who drink water beforehand, suggesting caffeine consumption causes improved cognitive performance. This study is known as a:
a. Statistical replication
b. Replication plus-extension (NOT ANSWER)
c. Conceptual replication
d. Direct replication
Conceptual Replication can be defined as a procedure of repeated experimenting with different methods. The researchers in this method of experimenting performs the experiment of the underlying hypothesis with different methods to know the reliabilty of the result.
<u>In the given scenario, Mark has performed the experiment to determine if consuminh caffeine causes people to perform better on cognitive tasks but using different methods. The reliablity of hypothesis was checked by using different methods, first, Mark experimented on maths solving method then he performed the experiment of same hypothesis with different method of solving verbal analogies</u>.
Something develops when a persons personal employment changes but overall basic social status remains the same. For example, a doctor's employment may move from prescribing medications to instructing at a medical school, but their reputation and social position are expected to stay the same.
