Motor Learning Chapter 8

attentional focus

the information at which the performers attention or consciousness is directed

external focus

a focus on information that is the consequence of the action being produced ex: movement of a golf club, the flight of the ball

internal focus

a focus on information associated with the body's movement in producing the action EX. how much the elbow is bent, and the timing of hip rotation

narrow focus

a focus on a narrow range of information sources at one time

broad focus

`a focus on a wide range of information sources at one time

open-skill

a skill performed in an environment that is unpredictable or in motion and that requires performers to adapt their movements in response to dynamic properties of the environment

closed skill

a skill performed in an environment that is predictable or stationary and that allows performers to plan their movements in advance

anxiety

a person's uneasiness or distress about the future uncertainties; a perception of threat to the self (often characterized by elevated arousal levels)

arousal

the level of activation of the central nervous system; varies from extremely low levels during sleep to extremely high levels during intense physical or mental activity

process goals

targets for performance that focus on the quality of movement production

outcome goals

targets for performance that focus on the end result of the activity

massed practice

a practice schedule in which the amount of rest between practice attempts or between practice sessions is relatively shorter than the amount of time spent practicing

distributed practice

a practice schedule in which the amount of rest between practice attempts or between practice sessions is relatively longer than the amount of time spent practicing

blocked practice

a practice sequence in which individuals rehearse the same skill repeatedly

limited attentional capacity

the notion that attention is limited to atmost a few activities at one time

modeling

a practice procedure that involves the demonstration of a skill for the benefit of a person who is trying to learn the skill

observational learning

the process by which learners acquire the capability for action by observing the performance of others

guidance

a procedure used to direct (either physically,verbally, and or visually) learners through task performance in an effort to reduce errors or reduce fear

active guidance

a type of guidance procedure that involves active movement by the performer which tends to preserve a relative timing pattern and feel of the target skill

passive guidance

a type of guidance procedure that involves passive movement of the learner (e.g. the instructor moves the learners limbs through the fundamental pattern), which can alter the nature and feel of the target skill

simulator

a training device that mimics various features of a real world task

target skills

the skills a person wishes to be able to perform

target context

the environmental context in which people want to be able to perform a skill or skills

seral skill

a type of skill organization that is characterized by several discrete actions connected together in a sequence, often with the order of the actions being crucial to performance success

part practice

practice of a complex skill in a more simplified form; the three types of part practice are fractionization, segmentation, and simplification

fractionization

a type of part practice in which one or more parts of a complex skill are practiced separately

segmentation

a type of part practice in which one part of a target skill is practiced for a time, then a second part is added to the first and the two are practiced together, and so on until the entire target skill is practiced; also referred to as progressive part practice

simplification

a type of part practice in which the complexity of some aspect of the target skill is reduced (ex. slow motion practice, use of oversized ball)

component interaction

the extent to which actions involved in one part of a complex skill influence actions involved in other parts

motor program

`a set of motor commands that is prestructured at the executive level and that defines the essential details of a skilled action; analogous to a central pattern generator

specificity of learning

the notion that the best learning experiences are those that approximate most closely the movement components and environmental conditions of the target skill and target context

generalized motor program

a motor program that defines a pattern of movement rather than a specific movement; this flexibility allows performers to adapt the generalized program to produce variations of the pattern that meet various environmental demands

mental practice

the practice of a motor skill in the absence of overt movement

verbal cognitive stage

the initial stage of learning in which verbal and cognitive process dominate the learners activity

mental imagery

the mental practice technique in which people imagine themselves performing a motor skill from either a first person or third person perspective
