Fast Food Photo Study

The investigators aim to discover if people of different demographic levels are more or less attentive to changes in calorie information vs. changes in price information on a restaurant menu. The investigators will record whether the calorie/price change was noticed or not, as well as how quickly the calorie/price change was noticed, depending on condition and individual differences.

About this study

Participants complete a short study regarding their ability to detect "mistakes" in a printed version of a fast food restaurant menu. We ask participants to identify the differences between the menu board and a typical menu board at that location. Individuals list the differences that they find and have a chance to win a prize if they identify the most mistakes among participants recruited that day. The differences created will remain constant (e.g., featuring Pepsi products instead of the typical Coca-Cola offerings, including items from other restaurants on the menu), including changes to calorie labels and price labels. Additionally, we recruit participants in a variety of locations to test for differences between demographics (e.g., income groups, education levels, and BMI levels).
