Lecture 21: Developmental Perspectives Flashcards
how should we think about age ranges?
as a measure of central tendency rather than a rule
rates of development in children
Children vary a lot in when they develop certain capacities
how do we infer novelty?
from eye gaze duration
the habituation paradigm
as a stimulus becomes less novel, infants look at it less
looking time can access
- Recognition of novelty, difference, or change
- Preference
Recognition of novelty, difference, or change
when a pre-existing stimulus has been completely encoded
preference
when a pre-existing stimulus hasn’t been completely encoded
novelty and gender study method
- Habituate 5-6-month-olds to a photo
- See a new photo of someone similar or different in gender or age
- measure the time spent looking at the photo
novelty and gender study findings
Found that while kids have some idea of gender, they have a more nuanced facial perception that goes beyond gender
habituation
complete encoding, so recognition
preference and race study method
had white newborns and 3-month-olds view images of people from different races (no habituation) and measured their looking time
preference and race study findings
- Newborns: there was no-race based difference in looking time
- 3-month-olds: there was more looking time for white faces
what do preferential-looking studies reveal about race preference development?
that nonverbal preferences based on race develop with experience
Two rules for when awareness of social categories develops
- Visibility of social category
- The primacy of social category in everyday life
when does the awareness of gender develop?
early (2-3 years)
when does the awareness of race and ethnicity develop?
later (5+ years)
