Definition
| skill - a task that has a specific goal to achieve (action goal) |
|
|
Term
|
Definition
•Actions are goal-oriented activities that consist of body and/or limb movements
•Common motor skills share these characteristics and need to be learned |
|
|
Term
| •3 reasons for distinguishing movement from skills and actions: |
|
Definition
•3 reasons for distinguishing movement from skills and actions:
•People learn motor skills and actions
•People adapt movement characteristics to achieve a common goal
•People evaluate actions and movements with different types of measures |
|
|
Term
|
Definition
| •Gross motor skills (requires the use of large musculature to achieve the goal of the skills, i.e., walking, jumping) |
|
|
Term
|
Definition
| •Fine motor skills (requires control of small muscles to achieve the goal of the skill, i.e., hand/eye coordination) |
|
|
Term
|
Definition
| •Continuous motor skill (arbitrary beginning and end points; these skills involve repetitive movements, i.e., steering a car) |
|
|
Term
|
Definition
| Discrete motor skill (defined beginning and end points, usually requiring a simple movement, i.e., flipping a light switch – a one-movement skill) |
|
|
Term
|
Definition
•Serial motor skill (involving a series of discrete skills, i.e., using a stick shift in an automobile)
at least 3 subskills must be involved |
|
|
Term
|
Definition
•Closed motor skill (motor skill performed in a stable or predictable environment where the performer determines when to begin the action, i.e., picking up a cup while seated)
ex. dart throwing - because the height and distance of the board is always the same |
|
|
Term
|
Definition
•Open motor skill (motor skill involving a non-stable, unpredictable environment where an object or environmental context is in motion and determines when to begin the action, i.e., running a race with other runners)
ex. boxing
ex. swimming in ocean of sharks
ex. surfing |

Term
|
Definition
| Taxonomy is a classification system organized according to relationships among the component characteristics of what is being classified |
|
|
Term
|
Definition
| Regulatory conditions which are characteristics of environment that control the movement characteristics of an action |
|
|
Term
|
Definition
| •Intertrial variability refers to regulatory conditions during performance are the same or different from one attempt to perform the skill to another |

|
Term
|
Definition
| more than one signal, each signal has a specific response |
|
|
Term
| discrimination reaction time |
|
Definition
| more than one signal, only one response |
|
|
Term
|
Definition
| quiet interval of time between the onset of stimulus and beginning of activity |
|
|
Term
|
Definition
| period from the increase in muscle activity untilt he actual limb movement |
|
|
Term
mental procesing time/
pre-motor reaction time |
|
Definition
| when youre thinking about what youre going to do after the intial stimulous |
|
|
Term
|
Definition
| the singals are being sent to your muslces and nerves but you have yet to start moving |

Term
|
Definition
| measures general accuracy for the 2-dimension situation |
|
|
Term
|
Definition
| analogous to variable error VE in one dimensional tasks |
|
|
Term
|
Definition
| common error score for continuous skills |
|
|
Term
|
Definition
| refers to the study of the role of force as a cause of motion |
|
|
Term
|
Definition
| •refers to descriptors of motion without concern for the cause of that motion |
|
|
Term
|
Definition
| spatial position of a limb or joint over a period of time |
|
|
Term
|
Definition
•description of motion without regard to force or mass. Includes...
•Displacement (spatial position of a limb or joint over a period of time)
•Velocity (rate of change in an object position with respect to time) |
|
|
Term
|
Definition
| reaction time will increase logarithmically as the number of stimulus-response choices increases |
|
|
Term
|
Definition
•refers to engagement in the perceptual, cognitive, and motor activities
•Associated with motor activities (i.e., performing skills)
•Activities may be performed consciously or non-consciously |
|
|
Term
|
Definition
| •a.k.a. bottle neck theory, proposed a person has difficult doing several things at one time |
|
|
Term
|
Definition
| proposed attention limits were the result of the limited availability of resources |
|
|
Term
| Central Resource Capacity Theories |
|
Definition
| attention-capacity theories that propose one central source of attention resources for which all activities requiring attention compete |
|
|
Term
| •Three rules influence how people allocate attention resources: |
|
Definition
•enduring dispositions
•meaningfulness of the event (a.k.a. cocktail party phenomenon)
•Momentary intentions |
