The Gallery of Illusions from Eric Chudler's Neuroscience for Kids: This activity is a collection of interactive visual illusions. Students will be able to observe the illusion then move around parts of the display to demonstrate that their perception was incorrect. It is an excellent way to lead into a discussion on cortical processing of visual information. The web page can be accessed at http://faculty.washington.edu/chudler/flash/nill.html(Links to an external site.). I need to review the illusions, then answer the questions below.

Please answer the following questions in your response: At what level of visual processing is a visual illusion created?
