In this survey, we ask you to evaluate seven short videos from Youtube.

You are requested to watch each of the videos, read the comments posted underneath these videos, see how other users evaluate each of these videos, and answer a few simple questions about the videos and the comments.

Please watch entire videos and learn more about them by reading the comments, and seeing how other users evaluate it. Please use a computer to take the survey (mobile devices are not allowed). Please do not open any new browser windows nor tabs during the survey. On the next page, before watching the first video, please scroll to the bottom of the page to see what questions you have to answer. Only assignments that meet these requirements will be approved.

After you finish the evaluation, an identification will be generated to validate your participation on Mturk.
