Researchers at Georgia State University have studied to find information to suggest that monkeys and humans perceive optical illusions in a similar way. According to this study, we are similar in the way we perceive and misperceive the world. Capuchin monkeys and rhesus monkeys were tested on how they perceived the Delbouef illusion.The Delbeouf Illusion is a visual illusion where a dot is surrounded by a large ring, which is perceived by humans to be small then the same size dot surrounded by a small ring, in this case the ring creates a context in which the dots are perceived. They have found that humans and monkeys have similar perceptual systems. This study opens the door for using monkeys as a model to study human perception.
