We empirically investigate the impact of successful goal achievement on future effort to attain the next goal in a recurring goal framework.

With the mounting evidence that sedentary time has a negative impact on cardiometabolic profiles, health related fitness and physical activity, there is a pressing need to find an affordable adolescent physical activity intervention. One possible intervention that has been...

The mechanisms underlying honest signal expression remain elusive and may involve the integration of social and physiological costs. Corticosterone is a socially modulated metabolic hormone that mediates energy investment and behavior and may therefore function to deter dishonest signal expression. We examined the relationship between corticosterone and green badge coloration in male sand lizar...

Many websites rely on user-generated content to provide value to consumers. Often these websites incentivize user-generated content by awarding users badges based on their contributions. These badges confer value upon users as a symbol of social status. In this paper, we study the optimal design of a system of badges for a designer whose goal is to maximize contributions. We assume users have h...
