Dr. Mo T. Vadar, a professor of psychology at a respected university, is planning a study of the factors that affect the motivation of employees. Dr. Vadar is concerned that the results of his experiments may be misleading because employees in an experimental group tend to behave differently when they know they are being studied. This concern shows that Dr. Vadar is aware of the:

Hawthorne effect.

Explanation:

The Hawthorne effect can be defined as the proneness of people to work harder when they know they are the participants in an experiment. The Hawthorne effect was first discovered by researcher Henry A. Landsberger in the 1950s. Landsberger defined the tendency for working harder and improved performance by the workers for the short-term as the Hawthorne effect.

In the given case, Dr. Mo T. Vedar is aware of the Hawthorne effect as he knows that results can be misleading. Dr. Mo T. Vedar knows that people tend to work harder and show performance improvement when they are under observation or a participant in an experiment.

Thus, the Hawthorne effect is the correct answer.

swahili is an extremely rich and complex civilization, a set of ethnic groups articulated by a language and a series of cultural elements that fuse the african traditions, islam and indian culture. this growth was largely a result of the indian ocean trading network that brought in not just man-made riches, but also religious ideas, specifically islam, which had a significant impact on the local culture. furthermore, the development of the swahili language gave a common cultural unity to the people.
