ch 18: conclusion

Movements arise from the interactions of the organism, environment, and the task

newell’s model of constraints

Something that limits or discourages certain movements

constraints

Something that permits or encourages other movements

constraints

An individual’s unique characteristics

individual constraints

The individual’s body structure

structural constraints

The individual’s behavioral function

functional contraints

Goals of a movement/activity

task constraints

The property of the world outside of the body

environmental contraints

Equipment can be used to compensate for

individual structural constraints

Teachers and coaches can identify which _ to change to elicit the desired movement

constraints

As students grow and mature, other constraints can be _

changed in proportion

With growth and maturation, and individual’s _ constraints always change

structural

With growth and maturation, and individual’s _ constraints may change

functional

a measure of how test performance predicts behavior in real world settings

ecological validity

An analysis of how a particular task or skill is accomplished, focusing on critical components that influence movement

ecological task analysis

Ecological task analysis emphasized the interaction of _ constraints

environmental, task, individual

Ecological task analysis allows movement educators to create _ lesson plans and assess movement ability

developmentally appropriate

Ecological task analysis evaluates movement based on a

developmental continuum

During ecological task analysis, movement is labled as

correct, incorrect, recognizing change

ETA provides a way to _ a tst environment so performers can easily be compared with each other or themselves

standardize

More proficient movement might energy when constraints are adjusted for an individual’s constraints

environmental and task; structural and functional

The environmental can be structured to be more ecologically valid by using a

real world setting

and affects activity and performance for infants

position and level

It is easy to increase as skill improves

difficulty

is widely influenced by an interaction of multiple constraints

motor development

Optical motor development is likely related to the degree to which and _ are matched with individual constraints

practice opportunities, insightful instruction
