Study Notes
Depth Cues Overview
- Oculomotor Cues: Include accommodation and convergence; important for near objects.
- Convergence: More effective than accommodation for depth perception.
- Binocular Cues: Include stereopsis and depth perception created by input from both eyes.
Key Depth Cues
- Occlusion: Occurs when one object blocks another, indicating depth.
- Familiar Size: Recognition based on prior knowledge of an object’s size and perspective.
- Atmospheric Perspective: Distant objects appear hazy or blurred, indicating depth.
Visual Illusions
- Ponzo Illusion: Perspective convergence significantly influences the perception of size in this illusion.
- Ames Room: Constructed to seem rectangular, misleading depth cues cause distortion in size perception.
- Müller-Lyer Illusion: Misapplied size constancy contributes to the perception of differing lengths.
Stereopsis and Binocular Disparity
- Binocular Disparity: Crucial for depth perception; the difference in images between the two eyes.
- Stereoscopic Depth Perception: Achieved through slight differences in images presented to each eye.
- Random Dot Stereograms: Used to test binocular disparity; stimuli reliant solely on disparity for depth perception.
Development and Importance of Depth Cues
- Development of Binocular Disparity: Begins around 3.5 to 6 months in infants; significant for depth perception.
- Selective Rearing Studies: Showed the necessity of disparity-selective neurons for stereopsis.
Environmental and Contextual Influences
- Size-Distance Scaling Equation: Describes how perceived size (S) relates to physical size (K), retinal image size (R), and perceived distance (D).
- Apparent-Distance Theory: Explains moon illusion; overhead moon appears smaller due to surrounding sky perception.
Motion and Depth Perception
- Motion Parallax: Near objects appear to move faster than distant objects, providing depth cues during movement.
- Deletion and Accretion: Effective for detecting depth through changes in visible objects as one moves sideways.
Visual Angle and Perception
- Visual Angle: Width of an object perceived from a distance; thumb held at arm's length is approximately 2 degrees.
- Perception Variability: Influenced by known sizes of nearby objects and the viewing conditions.
Eye Disorders and Depth Perception
- Strabismus: Misalignment of eyes affecting depth perception due to reliance on one eye's input to avoid double vision.
Depth Cue Limitations and Applications
- Limitations of Familiar Size: Works best when depth cues are available; perception may vary without context.
- Use of Polarized Light in 3D Movies: Enhances depth perception by allowing each eye to see different overlapping images.
Miscellaneous
- Echolocation in Bats: Used for depth perception; an alternative to visual cues.
- Insect Depth Perception: Relies primarily on movement parallax due to their eye structure.
