AP 5-3 Perceptual Organization Intro

1. Gestalt Psychology: Studies how we naturally integrate pieces of information into meaningful wholes. Key principles include proximity, similarity, and closure in organizing visual information.

2. Figure-Ground: The ability to distinguish a figure from its background, allowing us to focus on specific objects while distinguishing them from their surroundings.

3. Depth Perception: Our ability to perceive the world in three dimensions and judge distances. This ability develops in infancy.

4. Depth Cues:

- Binocular Cues (require both eyes):

- Retinal Disparity: The difference in images between the two eyes.

- Convergence: The inward angle of the eyes focusing on a close object.

- Monocular Cues (one eye only): Include interposition, linear perspective, relative size, clarity, and texture gradient.

5. Perceptual Constancy: Perceiving objects as unchanging despite changes in lighting, distance, or angle. Types include size, lightness, and color constancy.

6. Perceptual Adaptation: The ability to adjust to altered visual fields, such as an upside-down or shifted view.

7. Perceptual Set: A mental predisposition influenced by expectations or prior knowledge, shaping how we perceive stimuli.

8. Context Effects: Immediate surroundings can alter how we perceive an object or situation.
