    Abstract
    Crowdsourcing has seen a substantial increase in interest from researchers and practitioners in recent years. Being a new form of work facilitated by information technology, the rise of crowdsourcing calls for the development of new theoretical insights. Our focus in this article is on extra-role behavior-employees' voluntary activities, which are not part of their prescribed duties. Specifically, we explored how user interface design can help increase extra-role behavior among crowdsourcing workers. In a randomized experiment, we examined the joint effects of the presentation of a performance display to crowdsourcing workers and the personal attributes of these workers on the workers' likelihood to engage in extra-role behavior. The experimental setting included an image analysis task performed on an environmental monitoring website. We compared workers' behavior across the different experimental conditions and found that the interaction between the presence of a performance display and the workers' personality trait of curiosity has a significant impact on the likelihood of engaging in extra-role behavior. In particular, the presence of a performance display was associated with increased likelihood of extra-role behavior among low-curiosity workers, and no change in extra-role behavior was observed among high-curiosity users. Implications for design are discussed.

    Abstract
    Online participation is becoming an increasingly common means for individuals to contribute to citizen science projects, yet such projects often rely on only a small fraction of participants to make the majority of contributions. Here, we investigate a means for influencing the performance of citizen scientists toward enhancing overall participation. Building on past social comparison research, we pair citizen scientists with a software-based virtual peer in an environmental monitoring project. Through a series of experiments in which virtual peers outperform, underperform, or perform similarly to human participants, we investigate the influence of their presence on citizen science participation. To offer insight into the psychological determinants to the response to this intervention, we propose a new dynamic model describing the bidirectional interaction between humans and virtual peers. Our results demonstrate that participant contribution can be enhanced through the presence of a virtual peer, creating a feedback loop where participants tend to increase or decrease their contribution in response to their peers' performance. By including virtual peers that systematically outperform the participants, we demonstrate a fourfold increase in their contribution to the citizen science project.
