Team up with two or more friends (the smallest acceptable group is three), and walk down the similar street or public area for around five minutes, without speaking to or looking at one other. When the time is up, go to separate locations and each make a list of the ten most interesting things you saw on your walk. Then compare your lists. Try and figure out how your individual patterns of perception might have affected what each of you noticed. Consider how such patterns might influence your response to artworks.
