Chapter 3 The First Two Years: Body and Mind Flashcards
birth weight does what at 1 year
triples
height at age 2 is typically what of adult height
half
newborns sleep hours
15-17
12 months sleep hours
12-13
sleep specifics vary because of
biology, caregiving, and culture
head sparing
biological mechanism that protects brain when malnutrition disrupts the body growth, brain is the last part of body to be damaged
early dendrite growth is called
transient exuberance
limbic system
produce emotions
amygdala
register emotions
babies need what or otherwise it stunts brain
simtulaiton
well known abusive head trauma in infants
shaken baby syndrome
hearing develops during
last trimester
least mature sense at birth
vision
pain and temp are often connected to
touch
gross motor skills
large muscles
- torso, back, legs, walk, jump
every basic motor skill develops over the first
2 yeats
cephalocaudal
we develop skills to do things with the top of our head before leg related
EX: holding head up first
proximodistal
we can do things closer to that central core than further away at the outskirts
EX: moving body to roll over before specific movements with hands
fine motor skills
small body movements
esp of hands and fingers
fine motor skills is shaped by
culture and opportunity
what is one thing that suggests infant brain has inborn readiness to learn
gaze following
gaze following
infants will naturally look to where someone else looks
2 types of infant memory
implicit
explicit
implicit memory
memory that is nonverbal
EX: memory for a movement
explicit memory
language dependent
EX: when I hear someone say outside I get excited
which memory type is longer to emerge
explicit
when are implicit learning strategies learned
early in life
schema
mental structure that processes information, perceptions, and experiences
assimilation
process of making new information part of ones existing schema
accommodation
the act of changing our though processes when a new object or idea doesn’t fit our concepts
equilibrium
balance between assimilation and accommodation
sensoimotor age
0-2
what does it mean that there are 3 circular reactions
no beginning or end to learning
circular actions lead to
cognitive development
primary circular reactions
focused within infants body
EX: sucking thumb is pleasurable
secondary circular reactions
outside of body
between baby and someone else
object permanence
objects continue to exist when they are no longer visible or detectable through the other senses
do we have object permanence before 8 months
no
at 18 months we have A not B error which is
do not understand movement of objects and will look in original spot
symbolic represenaton
language is an example of a symbol which represents something else
EX: baba=bottle
tertiary circular reactions
begin to take independent actions, experiments which are goal directed
includes wider world information gathering from experiments
how are infants similar in language development
they follow the same sequence
