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.
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).

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| 50% Prices/50% Calories | Experimental | The participant is exposed to the baseline menu, but the prices are edited to be at 50% of the actual price (e.g., a $1 coffee is listed as costing $.50) and the calorie labels are edited to be at 50% of the actual content (e.g., a 500 calorie Large Fries is listed as having 250 calories). In addition, the baseline mistakes are still included. This is the "Menu edited" intervention. |
