Summary

In this study, the investigators will test responsiveness of young, middle-aged, and older adults to a range of incentives, some of which provide rewards for the individual participants and others that offer rewards to other people or groups. The investigators hypothesize that incentives are differentially effective for different age groups.

Conditions

  • Physical Activity

Interventions

OTHER

Offering a financial incentive to increase walking

After a baseline week of walking while wearing a pedometer, participants will be randomly assigned to one of the five conditions. In each of these conditions, participants will have the chance to earn .02/step for each additional step per day (on average across the week, above baseline levels). After a week of incentivized walking, participants will again be asked to wear the pedometer for one final week (with no incentive). Because the investigators need a week of walking before the incentive week, it is important that participants do not know the specific incentive aspect at the beginning of the study. Therefore, the investigators will not disclose the incentive structure at the beginning of the study. The investigators will debrief participants at the end of the study, and they will be fully informed of the purposes of the study at that time.
