This is a mirror trace task that can be used in Qualtrics surveys.

You can try out the task here:

The easiest way to get started is to import two Qualtrics templates that are provided:

One of these templates shows how to screen participants to make sure they have a compatible browser/mouse. The other template shows how to use the task, providing each participant with 3 easy or difficult mirror-tracing tasks.

Details on how to use the task are embedded directly in the templates:

  • In custom headers, you set Qualtrics to point to the needed javascript
  • In each question you set some custom javascript to set the trial number and to record data from javascript back into qualtrics
  • In the scripts themselves you can define the trial images, starting and stopping points, etc.

It can seem a bit intimidating at first, but should be doable with a bit of work.

The script can upload screen shots of the users work to a server. This is turned off by default now.

I will be updating this github project as needed. If you want to complete a project and know that absoultely nothing will change without you knowing it, fork this project and then set your qualtrics surveys to point to the fork.

If you publish results with this task, please cite: Cusack M, Vezenkova N, Gottschalk C, Calin-Jageman RJ. 2015. Direct and Conceptual Replications of Burgmer & Englich (2012): Power May Have Little to No Effect on Motor Performance ed. J.M. Haddad. PLoS One 10: e0140806. PMID: 26536592.

And, as always, consider pre-registering your experiment and analysis plan, sharing your data and analysis script, being complete and transparent in how you report your results, and publishing in accessible repository no matter what the results.
