skill
capacity to control out bodies and the world around us
skill and actions
activities or tasks that require voluntary control over movements of the joints and body segments to achieve a goal
motor learning
the acquisition of motor skills, the performance enhancement of learned or highly experienced motor skills or the reacquisition of skills that are difficult to perform or cannot be performed because of injury or disease
motor control
how our neuromuscular system functions to activate and coordinate the muscles and limbs involved in the performance of a motor skill
motor development
human development from infancy to old age with specific interest in issues related to either motor learning or motor control
3 factors the influence motor performance
motor skill, performance environment, physical and psychological characteristics of the person performing the skill
behavioral level
researchers investigate questions by observing and analyzing human behavior as it is affected by the 3 influences
neurophysiological level
researchers directly or indirectly observe central and peripheral nervous system components as they interact with muscles involved in performing skills
skill
activity or task that has a specific purpose or goal to achieve, indicator of quality of performance
3 criteria of a skill
extent to which person can consistently achieve the goal, extent to which person can achieve goal under different conditions assess individuals level of skill and degree of efficiency
central concern of motor learning
understanding the charcteristics of skill and how we become skillful
purpose of a motor skill
cause some type of change in the environment or in the persons relation to the enviornment
cognitive skill
skill that requires mental activity, decision making problem solving and remembering
characteristcs of motor skills and actions
goal to achieve, performed voluntarily, requires movement of joints and body segments, need to be learned or relearned
basis for distinguishing motor skills from other skills
requires movement of joints and body parts to accomplish goal
movements
specific patterns of motion among joints and body segments used to accomplish action goals
movements
component parts of motor skills
one to many
one movement pattern could be used to achieve many goals
neuromotor processes
mechanisms within central and peripheral nervous system and muscular system that control movements and actions
3 reasons why movements are distinct from motor skills
people learn actions when they begin to learn or relearn motor skills, people adapt movement characteristics to achieve a common action goal, people evaluate motor skill performance movements and neuromotor processes with different measures
continuum approach
allows a skill to be classified in terms of which category the skill is more like rather than fitting one exclusively
characteristic that distinguishes categories of motor skills
the primary muscle groups needed to perform the skill
gross motor skill
motor skill that requires the use of large musculature to achieve a goal
fine motor skill
requires control of small muscles to achieve goal, hand eye coordination, precision with hands and fingers
serial motor skill
motor skill involving a series of discrete skills
discrete motor skill
motor skill with clearly defined movement beginning and end points usually requires a simple movement
continuous motor skill
motor skill with arbitrary movement beginning and end points, involves repepitive movements
environmental context
supporting surface, objects, and people involved in enviornent in which a skill is performed
stability
refers to whether the relevant environmental context features are stationary or in motion
closed motor skill
motor skill performed in a stationary environment where person determines when to begin the action, self paced
open motor skill
motor skill performed in a moving environment where the feature of the environmental context in motion determines when to begin action
general characteristics of all skills gentile
environmental context in which one performs the skill and the function of the action characterizing the skill
taxonomy
classification system organized according to relationships among the component charcteristics of the group of items or objects
regulatory conditions
features of the environmental context to which movements must conform if they are to achieve the action goal
intertrial variability
refers to whether the regulatory conditions associated with the performance of a skill change or stay the same
nonregulatory conditions
features of the environmental context that have no influence or only an indirect influence on movement characteristics
function of action
determined by deciding whether or not performing a skill involves moving the body from one location to another and whether or not the skill involves holding or using an object
body orientation
refers to the changing or maintaining of body location
body stability
refers to skills that involve no change in body location
body transport
refers to skills that require the body to move from one place to another
object manipulation
refers to maintaining or changing the position of an object
