Aim

Can newborns percieve depth?

When you look over the edge of a cliff, how can you tell that the ground is far away from you?

Gibson and Walk wanted to find out why children (and some animals) seem to innately know not to crawl over the edge of high objects to stop themselves from falling.

Multiple Choice

Being able to judge that something is far away from you using only your sight involves using....?

• visual depth cues

• binocular vision
• color perception
• peripheral vision

Multiple Choice

What is this apparatus called?

• The sight-related high ground

• The visual cliff

• Fake fall

• Checkered Chaos

Multiple Choice

Most babies would crawl to their mothers....?

• When their mother was on the deep side of the cliff

• When their mother was on the shallow end of the cliff

Draw

Draw what babies would do if their mothers ask for them to cross the deep side of the cliff to get to them.

Open Ended

So babies are more likely to avoid the deep side of the cliff and stay on the shallow side. What can you conclude about infant depth perception?

Multiple Choice

Which were the only animals that walked on either side of the cliff?

• Lambs

• Chicks

• Dark reared cats

• Light reared cats

Open Ended

What's the point of control experiments?

Why would it be an issue for this study if the infants could tell there was glass over the deep side of the cliff?

When moving objects close to you move faster than objects further away.

​Motion Parralax

Where infants using 'size' as depth cue?

To test this out, Gibson and Walk removed the deep end of the cliff and had two shallow sides instead.

One side had a large checkered pattern, the other side had a small checkered pattern.

Draw

Draw what you think this looked like.

Results

When rats were placed on the middle of the board, they preferred the larger squares compared to the smaller squares.

Multiple Choice

Even when the checkered pattern appeared to be the same size on both the shallow and deep sides, animals still preferred the shallow side of the cliff.

• True

• False

Multiple Choice

And which depth cue do we have an INNATE understanding of right from birth?

• Size

• Motion Parralax

• Convergence

• Binocular Disparity

Open Ended

Write a point and counter-argument using the topic of ecological validity.

Open Ended

Write a point and counter-argument using the topic of ethical issues
