motor development 0-6 Flashcards
neuro-maturationist view
stages occur as result of CNS maturation
- development spirals w/ alt periods of flex/ext dominance and symm vs asylum
- reflexes are building blocks
cognitive behavioral view
stages are empirical descriptions of behavior
interaction of ind w/ enviro drives development
pavlovian and operant response to enviro stim
cognitive paigetian view
alt periods of equilibrium and disequilibrium
interaction b/n cog-neural structures and enviro opportunities for action
reflexes–> voluntary action
motor learning theory view
cog -> associative -> autonomous
trial and error practice leads to motor program development
GMPs, shames = learning –> development
dynamic systems view
stages are relative stability arising from self organization
individual recognizes affordances in enviro - elects most appropriate repsonse
mult cooperating systems w/ individual rates of develop, self motivated exploration of enviro
anther, body mass, nutrition
overweight infants - physical development delay
iodine and iron - cog delays
gestational age
1st day of last menstrual period to day of delivery
full term
39-40 weeks
early term
37-38 weeks
premature
<37 weeks
corrected age
40 weeks - weeks premature
neonate
newborn
0-28 days
infant
0-12 months
toddler
1-3 years
asymmetrical tonic neck reflex
(primitive - ATNR - fencers) appears at 20 weeks gestration integrates 4-5 months stim: turn head response: facial arm ext, AB. occipital arm F, AB
rooting reflex
(primative)
appear 28 weeks gestation
integrates 3 months
stim: tough perioral area of hungry infant
response: turns head and lips toward stim
suck-swallow
(primitive)
appears 28-34 gestation
integrates 5 months
stim: touch lips and inside of mouth for suckling and liquid for swallowing
response: rhythmic excursion of jaw; tongue rides up and down w/ jaw; followed by swallow
palmar grasp
primitive 28 weeks gestation integrates 4-7 months stim: pressure on palm of hand response: flexion of fingers
plantar grasp
appears 28 weeks gestation
integrates 9 weeks
stim: supported standing on feet or pressure to sole of foot just distal to met heads
response: flex toes
galant
28 weeks gestation
integrates at 3 mo, inconsistent
stim: prone, stroke paravertebral skin
response: lateral of curvature toward side of stim
moro
(startle) 28 weeks of gestation integrates at 3-5 months stim: head drop backwards/loud noise response: ab, ext arms, splay fingers, may be followed by arm flexion and adducction
automatic walking/stepping
37 weeks gestation
integrates 3-4 months
stim: hold upright w/ feet on support
response: high stepping movements w/ regular rhythm
symmetrical tonic neck
STNR
appear 4-6 months post full term delivery
integrates 8-12
stim: flex or extension of head
response: w/ head flexion, arms flex, hips extend, w/ head extension arms extended and hips flex
general neonate and fist month
physiological flexion (from being in womb) typically moving when awake
neonate/1mo supine
wide movements of arms
recoil w/ passive ext
rhythmic kicking when active
