DVDs that reveal the surprising limits of perception, attention, and awareness


Viscog Productions was founded in 2003 with the goal of producing DVDs for use by consultants, teachers, trainers, and speakers. Our DVDs bring together effective video demonstrations from the growing field of Visual Cognition -- the basis of the "vis" and "cog" in our name. These easy-to-use presentation tools provide rapid, menu-driven access to a number of videos that can be used to induce striking failures of awareness in audiences.

Our first DVD, Surprising Studies of Visual Awareness, Volume 1 was released in 2003 and is used for training and education throughout the world. It includes the now-famous "gorilla/basketball" video. Surprising Studies Volume 2 was released in 2008, with an entirely new set of demonstrations and videos. It includes the famous "door" video and many others. Surprising Studies Volumes 1+2 also was released in 2008. It combines all of the demonstrations from Volume 1 and Volume 2 on a single DVD, allowing presenters access to all of the demos without needing to change DVDs during a presentation. All 3 DVDs are available only from this website (see our Products page).
