Perception and Drawing
•How can a simple line represent almost anything we can see or think of?
•Because linear elements and shaded areas trigger the perceptual “rules” we just studied
•Most preconscious—don’t have to think about “what things looks like”
–We experience “wholes” before parts, making parts more difficult to attend to
–Can learn to focus on detail and visual structure but brain helping you by not requiring this
•Learning to draw consists in part of
–Bringing some preconscious operations into consciousness (e.g., seeing a line, not the edge of a 3D form)
–Halting the process of object recognition and categorization
