Questions and Answers

What is depth perception?

The ability to perceive colors and textures
The ability to see things clearly at a distance
The ability to see things in three dimensions including length, width, and depth (correct)
The ability to see objects in low light conditions

What are depth cues?

Sources of information from within our body or from the environment that help us perceive how far away objects are (correct)
Clues that help us determine the weight of an object
Sounds that indicate the distance of an object
Visual signals that indicate the brightness of an object

What is stereoscopic vision?

The process of perceiving motion in still images
The ability to see colors vividly in bright light
The brain's ability to put together two 2D images to extrapolate depth (correct)
The ability to focus on objects at varying distances

What are primary depth cues and where do they originate from?

Primary depth cues are internal sources of information within our body that help us perceive how far away objects are. They originate from within our body. Signup and view all the answers

Explain how our brain is able to interpret depth from two 2D images on the retina.

Our brain's ability to put together two 2D images in such a way as to extrapolate depth is called stereoscopic vision. It interprets the slightly different images produced by each retina due to the separation of our eyes on our face. Signup and view all the answers

How is depth perception defined and what does it involve?

Depth perception is the ability to see things in three dimensions, including length, width, and depth. It involves the interpretation of visual cues that indicate how near or far away objects are. Signup and view all the answers

Why do our eyes, despite producing two-dimensional images on the retina, provide us with the perception of a three-dimensional world?

Our brains have the ability to extrapolate depth from the two 2D images through the process of stereoscopic vision, despite the images displayed on the retina being 2D. Signup and view all the answers

What role do external secondary depth cues play in depth perception?

External secondary depth cues are sources of information from the environment that help us perceive how far away objects are and therefore to perceive depth. Signup and view all the answers
