What is motor development?
development of movement abilities
What is motor learning?
movement changes that are relatively permanent but related to experience or practice
What is motor control?
nervous system's control of the muscles to permit skilled and coordinated movements
what is physical growth?
quantitative increase in size or and functional magnitude
what is maturation?
progress towards physical maturity
What is aging?
the process of growing older regardless of chronological age
What are Newell's 3 factors?
individual, environment, and task constraints
a_______ limits or discourages movement
also permits or encourages other movements
Individual contraints include
unique physical and mental characteristics ex. height, limb length, strength, motivation
________ relate to the individual's body structure
ex. height, weight, muscle mass and leg length
these constraints relate to behavior function ex. motivation, fear, experiences
world around us, global not task specific
ex. physical or sociocultural
goals of a movement or activity
ex. dribbling while running for b-ball players
If interested in what behavior is like now and why the behavior is that way. Motor Development or Motor Learning?
If interestedd in what behavior was like before our present observation, and why? Motor Development or Motor Learning?
If interested in how the present behavior is going to change in the future, and why. Motor Development or Motor Learning?
Longitudinal research Study
watch a group of a certain age for the entire length of period (could be years or decades)
cross-sectional research study
select individuals at chosen points within the age span
Advantage of cross-sectional research study over longitudinal research study?
researchers can study development in a short time
Disadvantage of cross-sectional research study over longitudinal research study?
never really observe change, only infer change from age group differences
a group whose members share a common characteristic, such as age or experience.
mixed-longitudinal or sequential research study
several age groups are observed at one time or over a shorter time span
