| What does visual brain do when images on the 2 retinas are different? |
|
Definition
1) stereopsis
2) integrate the two images so both are simultaneously used for single vision
3) avg. the luminances of the 2 images
4) use info to create new perceptions
5) suppress one of the images (binocular rivalry) |

Term
| Stereopic Depth Perception |
|
Definition
The greater the disparity, the greater the perceived depth.
related: stereopsis, disparity, crossed disparity and uncrossed disparity |
|
|
Term
|
Definition
| Observer perceives a constant amount of depth from a 3-D stimulus that is coming closer to the observer and presenting increasing amount of disparity as it approaches. |

Term
| What are not stimuli for stereopsis? |
|
Definition
| Brightness/Lightness, Forms (shapes) and Lines are not cues for stereopsis. |

|
Term
|
Definition
| 1 eye covered by darkened lens and watches a pendulum swing from side to side but instead perceives an elliptical path rather than the linear one. Neurons in brain integrate the info from monocular targets that are on non-corresponding points and so the patient sees the target displaced in depth. |
|
|
Term
|
Definition
| 1 eye is covered with darkened lens and when removed actually views the environment as less bright instead of more bright since uncovering the eye, its visual system is being stimulated w/ increased total retinal illuminance. |
|
|
Term
|
Definition
| large differences between the images on the rwo retinas cause a fight for dominance thereby resulting in alternation suppressions of parts of the eye. |
