Bottom-up

Top-down
• Task/goal oriented- Behavioral- Cognitive
• Constant linking and re-linking of visual and non-visual information.

Patterns
• At this level:
- different elements become either linked or segregated- visual processing is at its highest

The Gestalt Principles
• Gestalt can be translated as ‘shape’ or ‘form’
