Abstract

The present study examined how product placement and in-store advertisement affect food selections of approximately 100,000 customers across 2 different stores using an alternating treatments design embedded in a multiple baseline design. Our results documented a substantial increase in the sales of healthy food products and a concurrent decrease in the sales of less healthy items via simple environmental modifications. These data suggest an effective means of altering unhealthy food choices at store checkouts.
