Sensory vs.
Cultural
–Sensory Representations
Effective
because well
matched to early stages of neural processing
–Understanding without training
–Perceptual Illusions Persist
Physical World Structured
–Smooth Surfaces and
Motion
–Temporal
Persistence
–Structured Light +
Law of Gravity
Stages of
Visual Processing
–1 Rapid Parallel Processing
–Feature Extraction: Orientation, Color,
Texture, Motion
–Bottom-up processing
–Popout Effects
–Segmentation Effects:
Edges & Regions
–2 Slow Serial Goal-Directed Processing
–Object Recognition: Visual attention &
Memory important.
–Top-down processing
