Lecture 2- face perception Flashcards
visual acuity
define visual acuity
measure how clearly a person can see.
visual acuity is poor…
but…
- at birth
- bur rpaid increase in first 6 months and by 1yr near adults level.
first month in visual scanning infants focus on…
the edges of an object
visual scanning
by 2 months infants can…
focus on internal features
colour vision
newborns are able to distinguish between what colours
white and red.
what is an example of a preference test?
Fantz- tiem psent looking at different patterns- comparison
colour vision
around what month are newborns able to look at bold and bright colours
1 month.
what is a preference test?
present the newborn 2 stimuli at the same time and emasure which one the infant looks the longest at.
what is a habituation test?
show child over and over the same stimulus until they get bored and then another stimuli- if they are interested then it suggests that they can see a difference in the images.
conditioning as a test
reward target behaviour e.g. sucking, when tey habituate they may decrease sucking but if sucking increases then they can distinguish between two images.
what is the nativism approach to facial recognition?
the special perceptual process is organised at birth
empirical view of facial recognition
perceive faces as they perceive other objects it is just specialised due to experience.
what did Maurer and Barrera add to Fantz’s study
added controls for complexity
what did Goren et al change from Fantz original study
used moving stimuli stimuli instead of static so they moved the paddle in an arc over the infants field
findings
findings of goren et al’s study?
the infants did in fact track the schemtatic face over the other two even though it was moving.
