What are binocular cues?
|
Cues that need two eyes that give depth information
|
|
|
What is retinal disparity?
|
Basically both eyes see object slightly differently and brain takes these two images to assess depth of object. Space between the eyes that allows binocular vision to create depth perception
|
|
|
What is convergence?
|
Bionocular cue that gives humans an idea of depth as well based on how much eyeballs are turned.
|
|
|
Things far away (convergence), eyes: relaxed or contract?
|
Far away = relax, close to our face = eyes contract
|
|
|
What are monocular cues?
|
Cues that only need one eye for. Gives form, motion, constancy
|
|
|
What is relative size (monocular cue: form)?
|
Closer an object is, the more it is perceived as bigger
|
|
|
What is interposition (monocular cue: form)?
|
Overlap:One object is in front of another and the front object seems like it is closer to you even though both images are on the same plane
|
|
|
What is relative height (monocular cue: form)?
|
Things higher are placed physically higher on the image plane are percieved to be farther away than those that are lower
|
|
|
What does shading and contours say (monocular cue: form)?
|
Using light and shadows to percieve form (like depth)
|
|
|
What is motion parallax?
|
It is a monocular cue in which things farther away move slower, closer things move faster
|
|
|
What is constancy?
|
A monocular cue perception of object doesn’t change even if the image cast on the retina is different. Different types of constancy include size constancy, shape constancy, color constancy
|
|
|
What is size constancy (monocular cue: constancy)?
|
When an object appears larger because it is closer, we still think it is the same size
|
|
|
What is shape constancy (monocular cue: constancy)?
|
When an object changes shape but we still maintain the same shape perception. For example, a door opening means the shape is changing. But we still believe the door a rectangle
|
|
|
What is color constancy (monocular cue: constancy)?
|
Despite changes in lighting which change the image color falling on our retina, we understand (perceive) that the object is the same color.
