Development Flashcards
what is developmental pyschology? what does it focus on?
the study of psychological growth of individuals
focuses on pyschological responses that characterize the different stages of life
what are the stages of life?
prenatal, infancy, childhood, adolescence, early adulthood, middle adulthood, late adulthood
what are the 3 ongoing debates in developmental pysch?
nature vs nuture
continuity vs stages
stability vs change
what are the differences between the nature and nuture arguements? what is the better agruement?
nature = we unfold (maturation process) according to genetically predetermined processes
nuture = we are a blank slate at birth and the environment determines who we are
nature and nuture argumet = BOTH genetics and environment matter (most common perspective now)
what do twin studies/ genetics prove?
done at Bouchard U of Minnesota
pairs of identical (monozygotic - exact same genetic material) and nonidentical twins (dizygotic - share same uterine environment) raised together or apart
identical twins more likely to be similar whether raised together or not (personalities, traits alike)
*strong concordance rate between the two show that nature is important in development
what are critical periods? what concept are they linked with? what are sensitive periods?
nature concept
critical = a period in which experience must occur for normal development (language, visual info, attachment)
if one doesn’t find attachment in early stages (year 1) and if not nurtured there will be lasting damage - will not be able to form healthy attachments
ex. jeanie locked up for 13 years and couldn’t walk and had no grammatical structure
sensitive periods= easier to learn something
ex. foreign language
continuity vs stages
continuity = development is continuous (can go back and forth)
*adults quantitatively different from children because of higher end knowledge
stages = development occurs at different rates depending on factors such as age (need to master a certain task to move on to the next stage)
piaget, erikson, and kohlberg all researched based on stages
stability vs change
stability = individuals are stable from infancy to adulthood in terms of important personality/ temperament traits
change = the perspective that early childhood does not predict adult functioning
what is the biosychosocial model?
genetic disposition and environment - both make you who you are
continuity- physical development/motor skills
stages - cognitive skills
some traits are stable
what are life span developmental research approaches?
cross-sectional vs longitudinal research
what are the differences between cross-sectional and longitudinal approaches?
cross secitonal = different participants of different ages at one point in time (most common)
ex. sample for memory over the years in people that are 10,20,30,40..80 years in age
logitudinal = same participants are studied at various ages
*minimizes cohort effects between people (education, experience, all things that change over generations)
what are the advantages/ disadvantages of cross-sectional and longitudinal approaches?
cross-sectional = info about age differences, quick, larger samples BUT generalizability problem due to one time view, corhort effects problem
longitudinal = info about age changes, increase reliability, more info per subject BUT generalizability problem due to drop-outsm time intensive
what are the 3 important developmental theories?
piaget = 4 stages of cognitive development
kohlberg = 3 levels of moral development
erikson = 8 stages of psychosocial development
what did piaget study? what are the 4 stages?
cognitive development
- sensorimotor - birth to 2
- preoperational - 2-6
- concrete operational - 6-11
- formal operational - 11+
downsides? ages are approximate, stops at age 11 due to abstract cognitive thinking
what is cognitive development? who created it? what do newer theories prove?
the emergence of the ability to think and understand
- how physical world works, how mind represents it, how other minds represent it
jean piaget (1896-1980) created stages of cognitive development however
- newer theories see the stages as continuours, not discrete
- children may acquire abilities earlier than proposed
what are the 3 major concepts of piaget’s theory?
SCHEMA = cognitive structures consisting of organized ideas, theories about or models of the way the world works
ex. certain objects fit certain categories (stereotypes)
ASSIMILIATION = absorbs new info into schemas
ex. have a hard time letting go of prejudices - daughter thinks doctors are only girls
ACCOMADATION= adjust schemas for new info
ex. daughter had to accept that doctors are male too
what is the sensorimotor stage?
birth to 2
develop schemas through senses/motor
object performance develops (if you don’t see something, it still exists)
exploring world - very active stage
mirror video
at age 2 kids recognixe they are in a mirror
before this age they think there is someone else behind the mirror
what is the preoperational stage?
ages 2-7
*significant language develops
can think symbolically (ex. a cup as an actual oject)
cannot perform operations - ability to manipulate info in reverse (do you have a brother? does your brother have a brother?)
egocentric thinking - assume what they see/experience/think is the same in others
ex. if they are on the phone they will ask someone if they like their painting
theory of mind videoclip
john takes mary’s money - where does mary look when she returns?
age 3 - kids fail to read mary’s mind, think it is in john’s tin - think that mary knows what they know
age 4 - mary’s box
therefore, when kids learn their mind is separate from others, they can use skill to advantage and lie and play tricks
lying involves understanding what others think is different from their own thoughts and self-restraint
what is the concrete operational stage?
ages 7-11
can perform “operations” but concrete
understand “conservation”
ex. m&ms stretched out with less or more together with more - kids younger than this age pick the more stretched out m&ms
not abstract in thought process
ex. right to remain silent = don’t talk until told to, dont judge a book by its cover = reading a book may have bad art but could be a good book
what is the formal operational stage?
ages 11+
can think abstractly/hypothetically
some people with disabilities don’t reach this stage
what are the weaknesses of Piaget’s theory?
underestimated abilities
underestimated genetic and environmental influences
however. .. core stages DO fit
ex. school systems - when different things are taught to kids
