Studying visual perception in infancy
- Procedures can be used to study other forms of cognition/perception, but focusing here on visual perception
Fantz demonstrated that newborn babies could see (fixated longer at patterned objects)
- prefer to look at something than nothing
- at 3 months, look longer at same-race faces (prefer familiar faces)
Teller acuity card task - show baby two patterns, if infants can see they will look at stripe pattern over the boring solid gray pattern
- as the presenter shows additional cards, pattern gets smaller and smaller. If the infant doesnt show preference for a size card, that is their visual acuity
Visual paired comparison task - infants typically look at novel objects, show objects paird to see which ones they remember, or distinguish
- Results:
- 6 and 9 month olds could tell human faces apart
- 6 month old babies could tell monkey faces apart, but 9 month old faces could not
- Could not means that 9 months old could not tell the difference between old and novel monkey faces
- Infants experience narrows with experience
- With experience with faces, infants become ‘human experts’
- Another example:
- With the same face, infants considered the same face novel if it had a different expression (habituate to smiling face, novel when person had a frowning face)
