Dear Friends,

My research team is contemplating posting an experiment on MTurk, however, we are not sure how the subject ID number should be assigned to assure the correct randomization of the in-built experimental conditions and also how to generate the MTurk code at the end of the study for Ps to enter on Amazon for compensation.

I would be very thankful for any information on this issue.

Kindly help!

Generally, those questions concern MTurk rather than Inquisit. I would thus encourage you to study MTurk's documentation for answers.

#1:This entirely depends on how you set up the experiment in the first place. I.e., how many conditions are there? How do you plan to assign participants to those conditions? Via subject id or group id? Should they be randomly generated, subject-entered, passed by query parameters, etc.?

#2: Use Inquisit's <expressions>, <values> and the various available functions to generate a unique code and display it to subjects at the end of your Inquisit experiment. Have participants submit that code to MTurk. Match the codes between Inquisit and MTurk to establish "proof of work".

Thank you so much Dave! :)

I will follow your suggestions and will also refer to the links. I have used MTurk several times but with surveys built on Qualtrics, however, this will be the first time we will use Inquisit and so wasn't sure where to start from.

Again, thanks a ton!
