Participants needed for consumer study on soft drinks

March 25, 2013

Participants are needed for a study on consumers' purchase decisions about soft drinks. ASU's Carola Grebitus and Karen Lewis in the Morrison School of Agribusiness and Resource Management are making appointments for interested individuals.

The study will take place on the Polytechnic campus, and participants will be paid $30 as a compensation for their time. Participants also have the chance to win an additional $153, but must be at least 18 years of age and must have purchased Pepsi in the past year.

Study subjects will be given the chance to buy one 20 ounce bottle of soda, and will be asked to provide demographic data, attitudes and information about their use of soft drinks. Participants will further be asked to taste samples of different types of cola. Additionally, they will be asked to taste a small amount of a few different types of energy drinks.

The one-time test will take approximately one hour. According to the researchers, expected risks or discomforts are non-existent. Participation is totally voluntary and participants may leave the study at any time without penalty by notifying the project staff.

Testing will be conducted in the Consumer Research Laboratory on the Polytechnic campus from April 2 through April 7. Appointments will be made to start at 10 a.m., noon, 2 p.m., 4 p.m. or 6 p.m.

If you qualify and are interested in participating, email or call Karen Lewis at or 480-205-9792. Indicate a preferred date and time by noon on April 1. You will receive a confirmation email.

The laboratory is in the Agribusiness Center. Posted signs will direct participants to the testing site. For questions, contact project researcher Carola Grebitus at or 480-727-4098.
