Peer production communities like Wikipedia often struggle to retain contributors beyond their initial engagement. Theory suggests this may be related to their levels of motivation, though prior studies either center on contributors’ activity or use cross-sectional survey methods, and overlook accompanied changes in motivation. In this talk, I will present a series of studies aimed at filling this gap. We begin by looking at how Wikipedia editors’ early motivations influence the activities that they come to engage in, and how these motivations change over the first three months of participation in Wikipedia. We then look at the relationship between editing activity and intrinsic motivation specifically over time. We find that new editors’ early motivations are predictive of their future activity, but that these motivations tend to change with time. Moreover, newcomers’ intrinsic motivation is reinforced by the amount of activity they engage in over time: editors who had a high level of intrinsic motivation entered a virtuous cycle where the more they edited the more motivated they became, whereas those who initially had low intrinsic motivation entered a vicious cycle. Our findings shed new light on the importance of early experiences and reveal that the relationship between motivation and activity is more complex than previously understood.
