Preventing duplicate responses

[cww3]

Thank you very much! The attached questionnaire file is for an experimental condition. In a control condition, something like <randctrlword1> and <randctrlword2> would replace <maxideal1> and <maxideal2> for the essay questions.

Please let me know as soon as possible -- the grad student I am doing this for needs to run her experiment next week, and she just recently changed her experiment, otherwise I would have posted my question much earlier. Thanks again!
