Gibson's theory

Definition

Gibson's theory, also known as the ecological approach to perception, suggests that our perception of depth is primarily influenced by the information present in our environment. It emphasizes the role of visual cues and direct interaction with the environment in perceiving depth.

Visual Cues: Visual cues are any features or characteristics in our environment that provide us with information about depth and distance. For example, overlap (one object blocking another), relative size (larger objects appearing closer), and linear perspective (parallel lines converging) are all visual cues that help us perceive depth.

Binocular Cues:

Binocular cues are visual cues that require both eyes to perceive depth accurately. Examples include binocular disparity (the slight difference in images seen by each eye) and convergence (the inward movement of our eyes when focusing on nearby objects).

Monocular Cues:

Monocular cues are visual cues that can be perceived with just one eye. These cues include relative size, texture gradient (gradual change in texture as it recedes into the distance), motion parallax (objects closer to us appear to move faster than those farther away), and aerial perspective (hazy appearance of distant objects due to atmospheric conditions).
