Experiment Movie Player

Have you ever run an experiment online that required people to watch a video and then found that participants skipped the video entirely? Perhaps they just hit “Continue” or they found another way around your system, and you thought to yourself “Gee, I wish I had something that would stop them from hitting “Continue” until the video is over”. Well, here’s that code. The Experiment Movie Player (EMP) consists of 2 files which can be used together to show a flash movie and only allow the participant to continue when the video reaches a certain point or finishes.

The code is free for researchers to use provided they cite it in their research, using the citation below. Questions or comments on the EMP can be sent to me using the Contact link above!
