Who's the boss?: requester transparency and motivation in a microtask marketplace.

Workers on crowdsourcing platforms such as Amazon's Mechanical Turk often receive little to no information about who is requesting the task they are asked to perform. This can lead to psychological distance and reduced work quality as a result. In this study we varied the amount and type of information provided about the requester of a task on Mechanical Turk (no information, text only, or text and picture) to see its effect on the amount of work completed. We found that providing information about the work requester led to increased effort, with further differences in effects depending on the location of the task participants.
