A Novel Computerized Real Effort Task Based on Sliders

In this note, we present a novel computerized real effort task based on moving sliders across a screen which overcomes many of the drawbacks of existing real effort tasks.  The task was first developed and used by us in Gill and Prowse (2009).  We outline the design of our "slider task", describe its advantages compared to existing real effort tasks and provide a statistical analysis of the behavior of subjects undertaking the task.  We believe that the task will prove valuable to researchers in designing future real effort experiments.
