Week 1.2 Theories of Motor Development Flashcards
who came up with the nature theory, what was the name
Arnold gesell
neural maturationist theory
describe the neural maturationist theory
- preprogrammed brain,
- CNS driven
- primitive reflexes
- motor milestones are the best way to monitor
who cane up with the nurture theory, and what was it called
cognitive theory, skinner
what is the cognitive theory
you are the product of the environment, learning and reinforcement
McGraw looked at two boys, Jimmy and Johnny, what was the outcome
Johnny was the weaker twin, but was given more in his environment, like roller-skates and Resistance training, Jimmy was not given this. Both reached the major milestones at the same time, regardless of the enviro. However, Johnny was stronger and more agile later in life.
what did Bernstein say. example?
that motor development was task specific, and not muscle specific. the task can be the same, but the muscles different
EXAMPLE: writing your name, right vs left hand.
who came up with the dynamical systems theory
Thelen
what does the dynamical systems theory say
motor tasks can be done in many ways, the brain and the enviro, and the body will all shape the development of movement
elaborate on reflexive newborn stepping within the DST
the stepping may be pre-programmed in spinal cord circuits, but the development will depend on the environment, individual, their strengths
