In this month’s lab meeting, Dr. Koji Yoshimura and Dr. Marthe Möller demonstrated the usage of Gorilla, an online tool for building experiments. The session focused on setting up a basic experiment in the tool, how this set-up differs from Qualtrics as the main survey tool used at the University of Amsterdam, and the role of interactive features. Specifically, the session focused on embedding hatboxes within studies as well as embedding real time response measures.
