Question

Many researchers devise “sham” treatments for their control groups to undergo, meaning that the control group interacts with researchers in some way that is not thought to impact the dependent variable or the outcome. This is done to weaken the argument that the treatment group improvement may have occurred in part simply due to the attention this group received from the researchers. These researchers are attempting to control for which of the following? a. multiple treatment interference b. the Hawthorne effect c. selection d. experimenter effects

Explanation / Answer

the Hawthorne effect.

Hawthorne effect refers to the altering of behaviors if the subjects come to know that they are being observed. So, it becomes important for the researcher to ensure that the results are not influenced by any other factors except the assigned variables. It’s also to done to bring the participants to normalcy thus making them understand about the seriousness of the research.
