A

When constantly exposed to an unchanging stimulus we become less aware of it because our nerve cells fire less frequently.

127

A

Infants between 6 and 14 months hesitate to crawl over the visual cliff.

Q

What is the cultural influence on depth cues? Provide an example?

A

People in various cultures don’t have the opportunity to learn through magazines, books, computers and etc. The objects [(magazines, books, and computers are (3D)] but what’s on the object are (2D). They only learn through (3D) experiences.
