Study Notes
Gestalt Principles
- The whole is different from the sum of its parts.
- Figure-Ground Perception allows us to identify an object from its surroundings.
- The brain highlights important stimuli while filtering out irrelevant details.
Binocular Depth Cues
- These cues rely on two eyes being spaced apart.
- Each eye views the world from a slightly different angle.
- This difference creates two distinct images.
- Stereopsis combines these two images to perceive depth and distance.
Retinal Disparity
- Each eye sees a slightly different picture due to their separate positions on our face.
- The brain uses these differences to determine how far away things are, helping us see the world in 3D.
Convergence
- Our eyes move inward toward each other to focus on a close object.
- This eye movement helps us understand how near something is, aiding in our perception of depth.
Monocular Depth Cues
- Visual indicators of distance and space that can be perceived using just one eye.
- These help us understand how far away things are (depth).
Shape Constancy
- Our ability to perceive an object as having the same shape, even when our angle of view or the distance from which we see the object changes.
- This allows us to recognize objects regardless of the perspective from which we view them.
Size Constancy
- Our perception that an object remains the same size, even when its distance from us changes, causing the image on our retina to grow or shrink.
- This allows us to accurately judge the size of objects regardless of changes in their apparent size due to distance.
Color Constancy
- Ability to perceive colors of objects as stable under varying lighting conditions.
- Even when lighting changes, we still see the object as having the same color.
- This helps us identify and differentiate objects in our environment consistently.
Apparent Movement
- Perception of motion when there isn't any actual movement.
- Creates the illusion of motion from a series of still images.
- Underlies animations, movies, and digital billboards.
Linear Perspective
- A technique that uses converging lines to create the illusion of depth on a flat surface.
- Objects appear smaller and farther away as the lines converge in the distance.
Relative Size
- Objects that appear smaller are perceived as being farther away than larger objects.
Texture Gradient
- Closer objects appear to have more detail and texture than objects further away.
Interposition
- When an object partially blocks the view of another object, the blocked object is perceived as being farther away.
- This is also known as occlusion or overlapping.
Perceptual Set
- A predisposition to perceive things in a certain way based on prior experience or expectations.
