Perceptual Cues Flashcards
Visual depth perception
The perception of cues that indicate the distance of an object.
Perceptual constancy
We see qualities of an object is constant. Size, shape, and brightness.
Monocular cues
Cues that do not use two eyes.
Interposition
Objects in front are closer.
Size
Larger objects are closer.
Linear perspective
Objects produce smaller retinal image as they’re farther away.
Texture gradients
Detail of texture is greater if the surface is closer.
Binocular cues
Cues that use two eyes
Binocular or retinal disparity
Binocular depth cute that depends on the distance between the two eyes. Because of their different positions, the two eyes receive slightly different images. The difference between these images is the retinal disparity. The brain interprets large retinal disparity to mean a closer object and small retinal disparity to mean a distant object.
Motion parallax
As you move your head, images of close things change position more quickly on the retina than images of distant ones.
Gestalt rules
Laws that the brain uses to group or organize elements of the scene.
Proximity
Objects near each other belong together.
Similarity
Objects that resemble each other belong together.
Continuity
Objects that form a continuous line belong together.
Closure
Objects that make up something we recognize belong together.
