Further Effects of Lottery Odds on Responding

Wine et al. (2017) worked with four adults in a day program. All had developmental delays.

Each person got a daily step goal. If they met it they drew a ticket from a bowl. Some tickets won small prizes. The team counted steps with cheap pedometers.

Three of the four adults doubled or tripled their daily steps after the lottery started. The fourth person stayed about the same. Staff and participants all said they liked the game.

Washington et al. (2014) tried a similar prize lottery with healthy office workers. Only one-third of them walked more. The new study shows the idea works better for adults with developmental disabilities.

Eussen et al. (2016) looked at thirteen health programs for people with intellectual disability. Most used several tricks at once: goals, feedback, and rewards. The lottery study keeps the same pieces but wraps them into one cheap package.

Kovačič et al. (2020) ran an 18-month diet-and-exercise plan. Adults with Down syndrome lost weight, but the program took a year and a half. The lottery gives faster step gains in weeks, not months.

You can cut prize costs and still keep people moving. Try a daily step goal plus a simple ticket draw. Start with one client, one bowl, and dollar-store prizes. Track steps for a week, then add the lottery and watch the numbers climb.
