Fundamental Concepts
I did not go for a run this morning because I lack the motivation is an example of this type of constraint.
What is functional constraint?
This describes the function and object in the environment provides to an individual.
What are affordances?
Inexperienced will optimize ________ at the expense of ________.
What is balance/stability and mobility/speed?
Built-in responses that facilitate survival.
What are reflexes?
Differentiated trunk rotation, sequential movements, and preparatory windup are common characteristics of this level of ballistic skill.
What is proficient?
The state of optimal functional integration of body's systems; ability to reproduce
What is maturation?
This theoretical perspective emphasizes the nervous system as the one system that triggers motor advancement.
What is the maturational perspective?
Improving balance always improves stability. True or false?
False
The types of infant reflexes.
What is primitive and postural (locomotor)?
Alternating step-hops on one foot, then the other. Coordination is often the rate-limiter for this form of locomotion.
What is skipping?
This type of research design incorporates both data collection over time and between different age groups.
What is mixed-longitudinal/sequential design?
An individual constraint or system that holds back the emergence of motor skill.
What is rate limiter?
The resistance if the change of motion related to mass.
What is inertia?
Stepping, crawling, and swimming are examples of this type of infant reflexes.
What is postural locomotor reflexes?
In early running, an example of children returning to old behaviors.
What is wider BOS, smaller stride length, arms higher guard, etc.?
A paradox that suggests development is both similar and different across individuals involves these 2 concepts.
What are universality and variability?
These 2 branches or approaches make up the Ecological perspective.
What are the Dynamic Systems approach and Perception-Action apporach?
You are standing in a Tiger Trails bus that constantly starts and stops. Give an example on how you could increase your stability.
What is widen BOS, lower COG, etc?
Spontaneous rhythmical movements.
What are Stereotypies?
2 common rate limiters for walking and running.
What are strength and balance?
The 3 definitive characteristics of motor development.
What is continuous, age-related, and sequential?
This approach states that how we interpret the world around and how we produce movement must be studied together.
What is the Perception-Action approach.
Force absorption is a principle of motion. Give examples of the 2 ways to reduce the impact.
What is (example that increases time of impact) and (example that increased area of impact)?
Infant reflexes appear and disappear. An example of atypical development.
What is exhibiting and reflex when they should not OR not exhibiting a reflex when they should.
________ of tasks is maintained with age, especially with practice.
What is accuracy?
