scriptingrt and mturk

I got a question by email and thought it would be best answered by a post:

First, is MTurk the most popular avenue for ScriptingRT?  Or is there another/better platform of access?

Mturk is definitely the best way to recruit participants quickly, and the data quality is reasonable. We also used facebook to spread a link to studies, but it is usually much slower. But note that we always use another platform, Qualtrics, to build a questionnaire around the scriptingRT. I guess it would be possible to embed a scripingRT file directly in a Mturk task, but I never tried that.

Also, is it possible to use either ScriptingRT or MTurk to create a design where a worker must complete several tasks (eg reading three sets of sentences over a span of 3-5 days) before being paid?

I guess yes. You could create one Mturk task that would have such a long duration. Alternatively, you could create one Mturk task for the first measurement point, and then invite your workers to do the second and third measurement points, stepping up the payment if they also participate a second and a third time.
