ch 5 Flashcards
dynamic system theory
child’s biological cognitive and socio emotional abilities form an integrated system
dynamic system theory one change in one part
changes entire system
how is everything connected exmaple, crawling
increased access to
new environments, new people, new experiences
how is everything connected exmaple, crawling pt 2
these new things will lead to better language, social skills, better self esteem
how does motor development occur
head to toe
proximal distal
gross to fine
why does sitting become before crawling
proximal distal
reflexes
involuntary response to a stimulus
why do we develop refelxes
usually critical to survival
critical reflexes
startle, rooting, swiming, stepping, sucking, grasping and stuff
relevance of reflex changes with time becasue
brain develops, coordinatino is gained, relfexes are exchanged for guided movement
motor control is a dynamic system
new wants new demands
reflexs get reorganized into guided movements and the cycle repeats
development is
maturation, experience, reorganizing old skills into new ones
sensation
collecting data from the 5 senses
just data
perception
prior knowledge on top of data to interpret the stimuli
cognition
process to store and organize data and apply our previous knowledge
sensation steps
- light into eye
2, projecting onto retina - info goes from rentia to primary cortex
then goes to perception
perception steps
- info goes from primary visual cortex to rest of brain
- brain adds knowledge to perceive it
macular degeneration
death of cone rich fovea
macular degen symptoms
need for bright light
poor adaption to low light levels
blurry
less intense colors
macular degen speed
slow or fast
rentinitis pigementosa
loss of rods in perphery (edge of vision)
tunnel vision like
retinitis pigementosa sympotoms
decreases vision at night/low light
tunnel vision
presbyopia
“old eye”
poor vision at near distances
presbyopia is
hardening of lens
weakening of muscles to focus
