Monocular Cues
1. Shadowing- gives info of 3D shape
2. Linear- parallel lines converge as they recede
3. Overlap-close objects block off view to more distant objects
4. Height in the horizontal plane- below horizon and lower down in our field of vision (closer)
5. Texture gradient- appears finer as distance increases
6. Relative size
7. Motion parallax- nearby objects move faster in the opposite direction
8. Clarity
9. Relative brightness- objects closer reflect more light
Binocular Cues
Binocular disparity- each eye sees a slightly different image
Stereopsis- brain combines two images
Accommodation and convergence- muscular cues
Perception of Movement
Movement of stimulus across the retina
Auto kinetic effect
Stroboscopic motion
Induced movement
Motion after-effects
Perceptual Constancy
Size constancy
Shape constancy
Location constancy
Brightness constancy (perceived brightness is relative to surroundings)
Colour constancy
Illusions
Physical distortion of stimuli
Misperception of stimuli- perceptual illusions
Distortions, ambiguous figures, paradoxical figures
