Art therapy uses the creation or viewing of art to help people discover and express their feelings. Unlike art for art’s sake, which focuses on the finished piece, art therapy (which typically employs paint, clay, charcoal, pastels, or other art materials) focuses on the process of creation itself. Moreover, the activity is undertaken primarily for its healing benefits rather than for the creative end result; in fact, the piece of artwork may never be shown to anyone outside the therapy session–and it is sometimes never finished.
