Abstract
We conduct an experiment to investigate how task autonomy affects intrinsic motivation. In the experiment, we study how autonomy affects performance directly through the opportunity to actively select a task in itself, as well as indirectly through the selection of a suitable task. Therefore, we investigate two complementing effects of task autonomy: an indirect (selection into tasks) and a direct effect (intrinsic motivation).

Primary Outcomes
Primary Outcomes (end points)
- Number of tasks completed by the subject (measured as the total number of tweets assessed and the total number of data rows transcribed)
- Time spent working by the subject
- Fraction of correctly completed tasks (only for one set of tasks)

Experimental Design
Experimental Design
Our experiment aims at establishing a direct effect of autonomy on intrinsic motivation and an overall effect on performance. To that end, we conduct a real-effort online experiment where subjects work on one out of two sets of tasks.

Experiment Characteristics
Sample size: planned number of clusters
500
Sample size: planned number of observations
500 individuals, 1 work period per individual
Sample size (or number of clusters) by treatment arms
We aim at n=200 participants for treatment Self-Selected, n=200 participants in treatment Assigned-Preferred that were assigned their preferred set of tasks. Additionally, we collect n=100 participants in treatment Assigned-Not-Preferred that were not assigned their preferred tasks, approximately n=50 for each set of tasks task.
