Psych 2ap3- oct 3rd Flashcards
What is the experiment for habituation/dishabituation
presenting them with a repeated boring stimulus, and then surprising them with something new. This is called dishabituating
What is the newborn externality effect
newborns look at the outside perimeter/contour of an object the most
How does experience impact perception in new borns?
As newborns grow, their experience fine tunes perception
What evidence suggests experience fine tunes perception?
- newborns dishabituated only to caucasian faces as they got older
- new borns stopped differentiating between the monkey’s and only could differentiate between human faces
What about auditory input? Can infants differentiate between that
yes
What evidence suggests infants can differentiate between auditory input?
phenomenal discrimination, presented with “ba” and once they got used to it, they dishabituated to “pa”
How old babies can discriminate phonemes?
1-4 month olds
What is an example from the powerpoint of fine tune perception?
Japanese babies aged 10-12 months lost ability to differentiate between law and ra because “r” sound does not exist in Japanese (fine tuned perception)
What are two different types of tests done towards infants to operatively condition them? What was their reward?
- high amplitude sucking (pacifier) test
- conditioned head turn
reward: hearing a particular song they have a preference for
What do infants prefer to hear in 4-6 months of age?
natural pauses and consonant over dissonant tones
What do infants prefer to hear in 9-12 months of age?
Musical scales and rhythms of own culture (eg: Indian music)
Why do infants prefer music of own culture?
Familiarity
How do infants take in/interpret multiple different sensory inputs?
They pick up on information that comes from multiple senses all at once, to make it into a bigger picture
What is a disorder that is similar to how infants experience sensory input?
synesthesia
How do infants also show signs of synthesia?
- associated “kiwi” with sharper object due to its sharp sound
- stared at the pacifier that was in their own mouth longer
