oTree project with a number of Real Effort Task (RET) example apps Edit
ret_typing is an oTree app that asks players to correctly type as many character strings as possible in a certain number of seconds. (set in settings.py >> ret_timer).
- The sequence of character strings is set in
models.py. This sequence is currently fixed, i.e. not randomly generated on the fly. - The length of the RET is set in
settings.py(see config fieldret_timer). If you want this to vary by period or subject or anything, seemodels.py>>Subsessionfor a good place to add additional logic. - The timer is handled by
views.py>>get_timeout_seconds - Converting the string to an image is handled by a js script in
templates/ret_typing/task.html>>Text to png Image. The string will actually appear in page source and via the Inspect element, but takes a little work to find it. - Results page has a complete log of RET attempts and accounting of one's score. You may want to tone that down, and reduce the amount of information given to subjects.
- Note in instructions, "Once you have entered your summation, click the Next button or press the Enter key." I found that some subjects ignored the second part of that sentence. Be aware that one's score can be significantly less if subjects are not aware of the just-click-enter-to-get-the-next-ret feature.
ret_adding is an oTree app that asks players to correctly add as many integers (set in models.py >> Constants) of as possible in a certain number of seconds (set in settings.py >> ret_timer).
