An animals' "umwelt" is the way in which they perceive the world. With the use of eye-tracking technology, we will present the gorillas with different images to explore the ways in which gorillas see and respond to their world. The overarching goal of this project is to determine visual processing patterns in the gorillas at the Buffalo Zoo and expand our understanding of how they see their world. In other words, this study aims to further our current understanding of the “gorilla umwelt.”
