theories of motor dévelopement

Question 1

4 theories of motor dev

Answer 1

• maturational
• biomechanical
• information processing
• ecological

Question 2

Maturational theory of dev

Answer 2

• innate process by a genetic, biological time clock
• environmental factors = rate of development

Gesell + McGraw

Question 3

bio-mechanical theory of dev

Answer 3

• normative descriptive period
  —>normal maturation (how mvt is being done)
• biomechanical descriptive period
  —> fundamental skills (defining each of those skills

Question 4

information processing

Answer 4

motor learning and dev = computer like
external input received, interpreted, stored = new motor skill
memory, attention and feedback mechanism

Question 5

which theory of motor dev is still used today

Answer 5

ecological perspective

Question 6

what is the ecological perspective theory of motor dev

Answer 6

inter-relationship between: env, task and individual

Question 7

two branches of the ecological perspective

Answer 7

• dynamic systems (motor control and coordination)
• perception-action

Question 8

Dynamical systems of the ecological perspective

Answer 8

-spontaneous, self-organization of body systems = mvt
- mvt behaviour not hard wired
(greater flexibility for indv needs)
- a multitude of interacting constraints (rate limiters, controllers)

Question 9

Perception-action of the ecological system

Answer 9

affordance: function an environmental object provides and individual
Body scaling: the use of intrinsic rather than extrinsic dimensions

Question 10

Newell’s model of constraints

Answer 10

mvt is affected by indv, task and env constraints,

one affected will change the overall pattern of a mvt

Question 11

Individual constraints

Answer 11

INTRINSIC DYNAMICS
- structural constraints (body structure change)
*will change more slowly overtime
- Functional constraints (attention, motivation, fear, experience)
* change over a shorter period of time

Question 12

Task constraints

Answer 12

-external to the body
- skill specific (goal of mvt, rules guiding performance, equipment)
*useful to manipulate to help kids learn

Question 13

Environmental constraints

Answer 13

• outside the body (properties of the world)
• Global (not task specific)
• physical (gravity, surface)
• sociocultural (gender roles, cultur norms)
