Terms
undefined, object
copy deck
- myelin
- fatty substance around neurons that transmits nerve impulses
- dynamic systems
- developmental change is nonlinear and discontinuous
- factors affecting probability of self-regulatory process
-
-duration of deprivation
-severity of deprivation
-age of the child
-level of motivation to make improvements - sensitive period
- a time frame or a window of opportunity when the learning of specific new skills is easier and quicker
- integration
- the coordinated interaction of opposing muscle and sensory systems
- explanatory devpt
- to know what causes changes to occur
- differentiation
- progression from the gross globular (overall) movement patterns to the more refined and functional movements
- development
- a change in functional capability
- transactional model of devpt
- the task, the individual, and th environment interact with eachother and have the potential to modify eachother to gain motor control and movement competence
- self-organizing
- humans strive for motor control and movement competence
- self-regulatory growth
- tendency to catch-up with one's age-mates upon recovery from an illness
-
lifestyle factors
(secular trends) - children are taller and heavier, and matured at an earlier age compared to earlier generations
- vitamin deficiences
-
vitamin D- Rickets
vitamin c- Scurvy
lack of protein- Kwashiorkor - ossify
- bones hardening
- factors of growth retardation (3)
-
-severity
-duration
-time of onset of undernourishment - later childhood (8-12yrs)
- slow increase in height and weight with more organization of sensory and motor systems
- hypertrophy/atrophy
-
hyper- muscle increase in size
atro- muscle decrease in size - motor development
- progressive change in movement behavior throughout the life cycle
- nonlinear/discontinuous process
- individual change is not smooth and hierarchial and doesn't involve moving toward higher levels of complexity
- average height/weight gain
-
height- 2" per year
weight- 5 lb. per year - early childhood (3-8yrs)
-
-boys and girls same muscle and bone mass
- descriptive devpt
- what children are typically like during particular age periods
- otitis media
- inflammation of the inner ear
- developmental variability
- age variations in the rate of movement skill acquisition
- physical growth
- increases in structure size in height, weight, and muscle mass
- cephalocaudal/proximodistal
-
cepha- head to feet devpt
proxi- center to distant - developmental sequence
- the orderly, predictable sequence of motor control
- factors affecting growth (4)
-
-nutrition
-exercise
-illness
-lifestyle - readiness
- conditions within both the individual and the environment that make a task easy for the child to master
