Figure 1: Example screen of real effort task given to participants, with the code for the first letter of the completed. “word” without mention of incentives or future rounds of the task. However, participants in the extrinsic incentive treatment groups were given an incentive to complete each word in the task during this round. The incentive given depended on the between subject treatment group see Section . Like the control group, the – participants in the in- centive groups were not told about future rounds at this stage either. Therefore, round 2 gives a measure of the effect of the incentives, given baseline intrinsic motivation measured in the practice round and round 1. After round 2, participants proceeded to round 3, which was the real effort task for another 5 minutes. There were no incentives given in this round; participants in the incentive groups were told this explicitly, whereas those in the control group were again just given the task without mention of incentives. This round gives a measure of whether the incentives crowd in or crowd out intrinsic motivation, given baseline intrinsic motivation measured in the practice round and round 1. Next the participants were given a time preferences task, which is explained in more detail in Section . This task was given to participants at this point to give them a break from the real effort task to test whether the patterns measured in round 3 persisted after a break. Thus, after the time preferences task participants were given the effort task in round 4 for another 5 minutes, with the same treatment as round 3. That is, no incentives were given, which was explained to those in the incentive treatments but not mentioned to those in the control. It was not mentioned that this was the last round of the effort task.
