Stereopsis Flashcards
What is stereopsis?
Stereopsis is the perception of depth or three-dimensionality that arises from the visual processing of two slightly different images from each eye.
True or False: Stereopsis relies solely on monocular vision.
False
Fill in the blank: Stereopsis is primarily associated with ______ vision.
binocular
Which part of the brain is primarily responsible for processing stereoscopic vision?
The visual cortex, particularly areas V1 and V2.
What visual condition can impair stereopsis?
Strabismus
Multiple choice: Which of the following is NOT a cue for depth perception? A) Stereopsis B) Motion parallax C) Color intensity
C) Color intensity
How does binocular disparity contribute to stereopsis?
Binocular disparity provides the brain with two slightly different images from each eye, which are combined to create a perception of depth.
True or False: Stereopsis can be developed in individuals who have never experienced binocular vision.
False
What is the typical range of distances where stereopsis is most effective?
Stereopsis is most effective at distances of about 0.5 to 10 meters.
Fill in the blank: The ability to perceive depth through stereopsis is crucial for ______ tasks.
fine motor
What is the term for the difference in images received by each eye that allows depth perception?
Binocular disparity
Multiple choice: Which condition can lead to a loss of stereopsis? A) Amblyopia B) Myopia C) Hyperopia
A) Amblyopia
What kind of tests can be used to assess stereopsis?
Stereopsis tests such as the Titmus Fly test or the Randot Stereo test.
True or False: Stereopsis is fully developed at birth.
False
What visual phenomenon can enhance the perception of depth alongside stereopsis?
Motion parallax
Fill in the blank: Stereopsis requires ______ alignment of the eyes.
proper
What age does stereopsis typically begin to develop in children?
Around 3 to 5 months of age.
Multiple choice: In which field is stereopsis particularly important? A) Photography B) Aviation C) Cooking
B) Aviation
What is the difference between stereopsis and monocular depth cues?
Stereopsis uses binocular vision for depth perception, while monocular depth cues rely on information from one eye.
True or False: Stereopsis can be improved with training in some cases.
True
What is an example of a monocular depth cue?
Relative size or texture gradient.
Fill in the blank: The ability to perceive depth through stereopsis is influenced by ______.
visual acuity
What is the primary reason for the effectiveness of stereopsis in depth perception?
The brain’s ability to interpret disparities between the images from the two eyes.
Multiple choice: Which disorder is characterized by misalignment of the eyes, affecting stereopsis? A) Cataract B) Strabismus C) Glaucoma
B) Strabismus
What role does experience play in the development of stereopsis?
Experience and visual input are crucial for the proper development and functioning of stereopsis.
