Your participation allows us to study the effects video representations in computer programs. You will view a set of key frames that have been extracted from a video clip. The video clip tells a story and these key frames you will see are meant to convey this story to you. You must pay close attention to the key frames. They will only be shown to you once, then you will be asked to complete tasks based on what you have viewed. You will receive several brief questionnaires about what you have viewed. In the first part of the experiment, you will view key frames for only one video. In the second section, you will view four sets of key frames (from four separate videos) at the same time.

If you have any questions, please ask the experimenter now.

Please read and sign the consent form given to you when you entered the experiment.
