Climbing the mountain of Motor Development
the mountain of development by Clarke and Metcalf suggests what about injury
you slide down the mountain into a different stage and have to work your way back up
the mountain of development by Clarke and Metcalf suggests what about aging
as you get older it is harder to climb mountains, you slide back down
what is the reflex period
prenatal - ~6 months
what is the concept of the mountain of development
as development time goes on we can climb the mountain with increased comprehension where being more skillful is at the top
in the reflex period, reflexes are a primary mode of …..
stimulating the CNS / PNS and engaging exploration of the perceptual motor landscape
three types of reflexes in the reflex period
primitive
postural
locomotor
what are reflexes useful for assessing
neurological condition
what are the survival / protection components of the primitive reflex
suckling
rooting (searching)
grasping
example of rooting in the primitive reflex
light touch on checks = head turns
what are the assessment methods of the primitive reflex
moro
startle
babinski
what is the moro assessment
arms and legs extend outward, its hands open and its fingers spread
what is the startle assessment
opposite to mono
what is the babinski assessment
reflexively fan out and extend its toes
what are examples of the postural reflex in the reflex period
head and body righting
labyrinthine righting reflex
pull up reflex
parachute reflex
what is the head and body righting reflex in postural reflex
gently turning the infants head or body in either direction, the body or head will follow
what is the labyrinthine righting reflex
enables upright posture
what is the pull up reflex
baby in sitting position, holding caregivers hands, will flex or extend arms to remain upright if tipped forward of back
what are parachute reflexes
protective and supportive, forward and downward
Ester Thelen suggests that it is the …….. that drives the disappearance of the stepping reflex
interaction between various body systems
stereotypies create …….. that help infants neural development
sensory experiences
what is the reflexive / spontaneous period
10th fetal week - 2 years
when is rudimentary behaviour
birth - 2 years
in rudimentary behaviour, the development of what loop controls occur
open and closed loop control
what is open loop control
fast, pre planned, ballistic actions
what is closed loop control
slower, guided by sensory information
what leads to slower sway in static posture
increased integration of sensory and motor information leads to slower sway
embodied cognition = cognitive processes, including thinking, are deeply grounded in our bodily interactions with the …..
environment
new postures are new….
affordances
inital creeping (crawling with belly of the floor) involves what movement
homolateral movement
who develops writing and drawing skills earlier and why
girls develop writing and drawing skills earlier than boys, due to earlier neurological maturity
what period is fundamental movement skills
2 years - 6/7 years
what are the characteristics of fundamental movement skills
- unique movement pattern
- near universality of outcome
- generalisation to a broad set of skills
what do kids learn when they develop fundamental movement skills
IPA / CPA = integrative / compensatory postural adjustments
APA = anticipatory postural adjustments
what is an important rate limiter in context specific period
important rate limiter is the development of perceptual cognitive capabilities
what is the compensation period
a time when the system adapts, or compensates for detrimentral changes in organismic constraints
