Top-Down Visual Processing

via http://the-guitar-store.net/used-gibson-guitars/

Here's an example of "Top-Down" visual design processing, almost to an extreme extent. The body of a standard Gibson SG electric guitar demonstrates its design worth without the need to even see it. The user, the guitarist, will play the strings by memory, focusing on the neck of the guitar if on the form at all. Despite this, the player will rely on the shape for comfort and positioning, similar to the design merit of a chair. Typical usage is generated from past experience and regularly adjusted touch/audio response, regardless of how impressive these may be to the eyes of the audience.
