What is depth perception? |
The ability to distinguish the distance of objects and the spatial relationships of objects. |
|
|
What are Visual Constancies? |
The ability to identify that particular objects stay the same, even when the image on our retinas are different. |
|
|
Why are infant studies carried out ? |
To distinguish whether perception is innate or is a result of learning and environment. (Nature vs Nurture) : IDA |
|
|
Which study is used to show the development of depth perception ? |
Gibson and Walk - Invested depth perception in neonates using a visual cliff. -A piece of glass that gave the illusion of a sheer drop. - Babies were placed on one side, and called to by their mothers on the other side. - 92% of babies did not cross. - Suggests development of depth perception is innate. |
|
|
Evaluate this study |
- Ethical issues - distress - Baby may not have crossed because it could have been their first time crawling on glass which could put them off. - When using goats - none crossed. - Infants were already 6 months old and could have learnt depth perception already. |
|
|
Which study supports this ? |
Campos - Found that babies heart rates were higher on the deep side of the cliif. - Shows awareness of both sides. |
|
|
Which study is used the show the development of visual constancies ? |
Slater et al. - Neonates were shown a small or a large cube in a number of trials. - Two cubes were then presented. - A larger one further away, and a smaller one closer so they appeared to be the same size. - All the newborns looked longer at the new cube, because they were used to it. - Supports the idea that visual constancies are innate. |
|
|
Why are cross-cultural studies useful ? |
Because if differences are found, it shows that perception is due to environment, rather than natural factors. |
