Starting the Learning Process at a
Young Age As early as the preschool
years
Basic skills = basis for otheractivities Walking, throwing, catching
Skill should be taughtcorrectly the first time toavoid development of badhabits

Providing Sufficient Learning
Time Without physical experience,
skills cannot be effectively
learned and maintained
Sufficient time must be allotted
for participating in PAs thatenhance movement skills

Being Taught By Qualified
Instructors Instructors, physical
educators, and coaches mustbe properly trained and have
experience with teaching PA
This means having trainedphysical educators fill such
positions, rather than math ormusic teachers who do nothave the necessarybackground

The Use of Quality Equipment
Safe, appropriate, and wellmaintained e.g., scaled down equipment for
children Lower basketball hoops
Smaller soccer nets
Lighter baseball bats
Effectiveness of teachingmovement skills is directlyrelated to the quality ofequipment

Three general stages of motor learning
have been identified
Each stage consists of:
Changes that occur as motor learning takes
place
Important features unique to each stage

12/49Sport Books Publisher 12
Cognitive or Acquisition Stage
Begins when task first introduced
Learner cognitively determines:
What the particular skill involves
Performance goals required to perform theskill
Instructions:
Are verbally transmitted (verbal stage)
Serve to convey the general concept of the
skill
Self-talk and verbal reminders facilitate
learning
Performance: slow, jerky, and awkward
-

Associative or Stabilization Stage
Focused on performing andrefining the skill
Concentration is directedtowards smaller details (e.g.,timing)
Performance: controlled andconsistent
Rapid performanceimprovements (somewhatslower than fist stage)
Diminished self-talk

Autonomous or Application Stage
Performance: automatic and veryproficient
Attention demands:
Performance improvements:SlowLess obvious (e.g., reduced mentaleffort, improved style, reduced anxiety)

16/49Sport Books Publisher 16
Information feedback: the information
that occurs as a result of a movement
Some information is received during the
movement and some is provided as aresult of the movement
Feedback is one of the strongest factorsthat controls the effectiveness oflearning

Extrinsic Feedback
Information that is providedto the learner by somebodyelse or some artificial means following aperformance outcome
Provides information above and beyond
what is naturally available to the learner(augmented feedback)
Can be controlled; when, how, how often

Extrinsic Feedback contd
Knowledge of results Information about the degree of success
Not effective when outcome is obvious
Important when outcome is less obvious
Knowledge of performance Information about the execution of a completed
movement
Example: took your eye off the ball, swing wasa little late, etc.

Motivational Properties of
Feedback Extrinsic feedback serves to motivate the
learner
Error correction Therefore, a skilled instructor should be able
to reinforce correct actions as well as point
out errors

Feedback Can be a Crutch
Providing feedback continuously for a
long period of time can lead to
dependency Occasional feedback tends to enhance
learning
Various types of feedback that minimizedependency have been identified

How Precise Should Feedback Be?
Descriptive (general) feedback
Indicates something you did, right or wrong
e.g., there was no follow through Prescriptive (precise) feedback
Provides you with precise correction statements
about how to improve your movements
e.g., snap your wrist more on the follow through
Precise feedback generates far better results

What is the Best Timing for Information
Feedback?
Short-term memory is very
susceptible to loss
Generally, the greater the delay of
information provision the less effect the
given information has
Therefore, immediate feedback is morebeneficial

Sport Books Publisher 32
Transfer of learning between two tasks
generally increases as the similarity
between them increases
Types of Transfer:Positive vs. negative
Near vs. far
-

Sport Books Publisher 33
Positive Transfer
e.g., Practicing drills and lead-up gameswith strong (positive) transfer to the
actual game
Learning can be positively transferredfrom practice to game situation whendrills are similar in nature to the criteriontask
-
7/30/2019 Motor Skills Learning and Acquisition Processes
34/49
Sport Books Publisher 34
Negative Transfer
Not common
Activities that may negatively transfer tothe criterion task need to be avoidedwhen performance is critical
e.g., playing mini-golf before golftournament
Factors Affecting Positive Transfer Negative Transfer

Factors Affecting
Transfer
Positive Transfer
Example
Negative Transfer
Example
Movement
Response/Patterns
e.g., tennis & badminton
Racquets
Net
Similar shot variations
Ball vs. birdie
Psychomotor Demands
e.g., rowing, kayaking, &
canoeing
Water
Dynamic balance
Coordination
Boat size and level of
balance
Cognitive Demands
e.g., basketball & handball
Game purpose Travel on the court
Biomotor Demands
e.g., sprint & long jump
Explosive power No take off and jump in
sprinting
Psychological Demands Narrow focus of attention
in archery and darts
Shifting attention in
hockey vs. judo and karate

Near Transfer
Desired when the learning goal is a taskthat is relatively similar to the training
task Transfer of learning is specific and
closely approximates the ultimatesituation
e.g., practicing various plays before avolleyball tournament
-
7/30/2019 Motor Skills Learning and Acquisition Processes
37/49
Sport Books Publisher 37
Far Transfer
Desired when interested in developing moregeneral capabilities for a variety of skills
Occurs from one task to another very differenttask
Best applies when beginning to learn a skill
e.g.,
overhand throw baseball throw, football throw,tennis serve, volleyball spike

Transfer Strategies
Training machines and stimulators
Whole vs. part practice
Lead-up activities and drills Mental rehearsal
-

Sport Books Publisher 39
Training Machines and Simulators
Closely mimic features of real-world task
Goal = positive transfer of learning from
simulator to the target skill
Effectiveness depends on the ability to
simulate motor as well as perceptual,
conceptual, and biomotor elements
-

Sport Books Publisher 40
Whole vs. part practice
Part practice Practicing independent
components of motor skill
Eventually, units of a task shouldtransfer to the task as a whole
e.g., gymnastics routine
Whole practice Practicing skill as a whole
e.g., golf swing
-

Sport Books Publisher 41
Part Practice
Effective for tasks serial in
nature and relatively long
duration
Effective as long as the
actions of one part do not
interact strongly with theactions of the next part (i.e.,
independent)
-
7/30/2019 Motor Skills Learning and Acquisition Processes

Sport Books Publisher 42
Whole Practice
Used with discrete tasks
of short duration where
components interactintensely
Practicing individual
components wouldchange the essence of
the skill
-

43/49
Sport Books Publisher 43
Progressive Part Practice
Used to avoid transfer problems due to high
levels of interaction among task components
Effective for any sequential action; e.g.,
tennis serve

Lead-up Activities and Drills
1. Transfer to another target sporting activity
e.g., passing, shooting, dribbling, and faking
drills for soccer
2. Improvement of basic abilities
Quickening, balancing, perceptual exercises,
etc.
e.g., perceptual motor training

Mental Rehearsal
The process associated with mentally
rehearsing the performance of a skill in
the absence of any overt physical
movement
Evidence has demonstrated that mentalrehearsal generates positively
transferable motor learning
Involves constructing model situations
and going through the motions of what
you will do later
Especially beneficial for injured athletes
It is a supplement to physical practice

Designing Effective Practice
Conditions of Practice:
a) Blocked Practice- a given task is practiced on many consecutive trials before
setting about the next task- enables the learners to correct specific problems and refinetheir skills one at a time
- important early in practice when correct habits should belearned
b) Random Practice- ordering of tasks is randomized in a way that tasks fromdifferent classes are mixed throughout the practice period
- random practice is very effective once a skill has becomemore developed
-

Massed Versus Distributed Practice
a)Massed Practice-a schedule in which the amount of rest between practice trials is short
relative to the trial length
-eg. 5 sec of rest for a practice trial lasting 60 secs.
b)Distributed Practice-practice that allows for more rest between trials relative to the trial length
-the rest period may last as long as the trial itself
Reducing the amount of rest between trials will also reduce the amount of
time the body and central nervous system have to recover from physical
and mental fatigue
There is no single optimal practice-rest ratio for all learning tasks
-

Grouping for Practice
Designed to make learning suitable foreveryone involved
Should be based on the learners skilllevels, rather than a subjectivedetermination of their underlyingabilities
Other factors, such as maturity level,previous experience, and level ofphysical fitness need to be considered

Effects of Motivation on Learning
Until the learner has been motivated, effectivelearning is not likely to occur
An instructor plays an important role in motivating hisstudents (encouraging learners to set goals,providing excellent demonstrations, or using visual
aids)
Its a Fact !: She who is motivated makes more of aneffort during practice, can practice for longer periods
of time, and learns more in the end The Law of Effect: Organisms tend to repeat
responses that are rewarded and to avoid responsesthat are not rewarded or punished
