To shed light on one of the more unique symptoms of COVID-19, Carthage is providing a scratch-and... The COVID-19 and Sense of Smell Study, run by the Psychological Science Department, will pay those who test positive for COVID-19 to answer some questions and test their sense of smell (in an easy, non-evasive way).

How does this work?

Upon receiving a positive test result, send an email to Then, we will provide you with an 8-Item Sensonics Smell Test (think the scratch-and-sniff books you had as a kid) and ask you to scratch and sniff. You’ll record your answers on a Google form and then receive $5 for your participation. Afterward, we will ask you to test again each week until your smell returns to normal. Once you complete the study, you get another $5. The test takes less than five minutes each week and is an easy way to make a few extra dollars.

Why is this so important?

In the fall, the Smell Study documented smell loss in most COVID-19 patients. Not only can smell loss be a great predictor of whether someone has the virus, but it’s also important to daily life. Now that we know smell loss occurs, we want to know more about how long it takes to recover.

Please consider participating in this study if you test positive this semester. It will benefit you, those around you, and the Carthage community.
