Intro to Psych Exam #2 Flashcards
(92 cards)
what three issues have engaged developmental psychologists
nature and nurture
change and stability
continuity vs. stages
course of prenatal development
zygote: fusion of egg and sperm
embryo: implantation of zygote to uterine wall - 10 days after conception
placenta: delivers nutrients from the mother to the embryo and fetus
fetus: point where embryo is clearly a human - around 9 weeks
fetus development
5-6 months baby begins to hear mom’s voice
28 weeks baby is likely to survive if born
baby begins to move down uterine tube and orient correctly when birth is imminent
effect of teratogens to baby
-fetal alcohol syndrome
teratogens
-certain chemicals pass the placenta barrier that the placenta doesn’t weed out
FAS
-more relevant term is Fetal Alcohol Spectrum
inborn skills
reflexes are responses that are inborn and do not have to be learned
types of inborn skills
rooting reflex
-baby opens mouth and looks for bottle/breast
sucking reflex
-know how to suck out milk
crying when hungry
newborns one hour old will look twice as long at an image that looks like a face
how do researchers explore infants’ mental abilities
Baby Lab
test how long they look and pay attention to different things
maturation
the average of our earliest conscious memory is 3.5 years
infantile amnesia
-during development of hippocampus
implicit vs. explicit memory
pruning
if you don’t use a part of your brain, you lose it
increases in first 1-3 years
allows brain to start using the areas that are helpful
increases at puberty
happens around 11-12 in boys, earlier in girls
brain development
fastest growth of all body parts
highest growth rate during middle trimester
at birst, brain is 25% of total size
by 2, it is 75%
most synaptic connections are developed
myelin sheath develo
sbrainstem (survival) develops first
between 3-6, frontal lobe develops rapidly
connection of R and L hemispheres can help children deal with trauma
motor development
takes place in the body and the cerebellum sitting unsupported - 6 months crawling - 8-9 months beginning to walk - 12 months walking independently - 15 months
frontal lobe and limbic system development
BOOK
Piaget
-Piaget’s theory
stage theorist as we learn we develop schemas Piaget's theory -sensorimotor -preoperational -concrete operational -formal operational
what is a schema
concept we have of an experience or a mental mold of the experience
how our mind makes sense of the world
schemas take place via
assimilation
-learn something new but assimilate it into a previous schema
-kid learns what a cow is; every animal is a cow
accommodation
-learn something new and alter/add new schema
-kid learns when an animal is not a cow
stage 1: sensorimotor
-object permanence
birth-age 2 senses and actions object permanence -point where child learns an object doesn't just disappear, it is just out of sight -begins around 9 months stranger anxiety -around 7 months -desire for primary caregiver rather than care from a stranger
stage 2: preoperational
- egocentric
- conservation
- theory of mind
until 6-7
think symbolically
-play house, have an imaginary friend
conservation
-if something changes shape, it doesn’t mean it’s changed volume
-children don’t understand this during this stage
egocentric
-“what I’m experiencing, you’re experiencing”
-hide in the corner during hide-and-seek
theory of mind
theory of mind
-what i know, you might not know
-age 4-5
example
-Sally puts ball in one cupboard and leaves
-Anne moves ball to different cupboard
-Anne thinks Sally will first look in the different cupboard
stage 3: concrete operational
age 6-11
can begin to understand mathematical concepts
understand conservation
mathematical transformations
cannot think hypothetically or abstractly
stage 4: formal operational
11+ personal fable -person believes they are unique -no one understands them -leads them to feel invincible imaginary audience -everyone is watching you hypothetical thinking
Lee Vygotsky
scaffolding
-recognize what they do and challenge
-moving towards higher cognitive functions by interaction
recognized our need for social interaction for learning
autism and the stages
BOOK
types of attachment
secure attachment
insecure-anxious attachment
insecure-avoidant attachment
secure attachment
when caregiver leaves, baby cries
when caregiver comes back, baby is soothed very quickly
baby calmed down quickly and wants to play again
