Theories of motor development Flashcards
4 theories
maturational
biomechanical
information processing
ecological
maturational theories
gesell and McGraw
innate process driven by a genetic, biological time clock
environmental factors = rate of development
bio-mechanical idea put forth by
ruth glassow
bio-mechanical theory
normative descriptive period
normal maturation
biomechanical descriptive period, fundamental skills
information processing theory names
bandura
skinner
information processing theory
motor learning and development = computer like
external input received, interpreted, stored= new motor skill
mechanism of information processing
memory, attention and feedback
all affect results
ecological perspective
relationship btw environment, task and individual
multiple system involvement vs only CNS
two branches of ecological perspective
dynamical systems (motor control and coordination)
perception-action
dynamical systems
spontaneous, self-organization of body systems = movement
rate limiters / controllers hold back or speed up development
perception action
affordance
body scaling
affordance
the function of an environmental object provides an individual
body scaling
use of intrinsic rather than extrinsic dimensions
newell’s model of constraints
individual constraints
intrinsic dynamics:
- structural contraints
- functional constraints
structural constraints
body structure changes
change more slowly over time
functional constraints
behaviour function
change over a shorter period of time
task constraints
external to the body
skill specific
skill specific - task constraints
goal of movement
rules guiding task performance
equipment used
environmental constraints
outside the body
global
physical
sociocultural
