Motor Skill Learning For Effective
Coaching and Performance

got to be excited about practice, because that's
my classroom.”

Definitions
Motor Learning:
A set of internal processes, associated with practice
or experience, leading to relatively permanent
changes in the capability for skilled movement
behavior.
Capability:
Once a skill is learned, the athlete shows a high
likelihood of exhibiting the same skill performance in
a consistent manner (although errors will still
sometimes occur).

How do we monitor motor learning?
• Through performance, an
observable behavior, and draw
useful inferences about learning
• Changes in performance are
relatively permanent, the
athlete should be able to
demonstrate the skill repeatedly

Phases of Motor Skill Learning
• Phases are continuous with no clear transition
between them
– Think of it like a continuum
• Athletes can be in different phases for different skills
• First proposed in Fitts & Posner’s model (1967)
– The Cognitive Phase
– The Associative Phase
– The Autonomous Phase

The Cognitive Phase
• Focuses on getting an understanding of how to
perform the skill
– Develop a motor program: an abstract, internal
representation of the skill – like a computer program with
instructions to guide movement
• Unable to attend to external events like teammates
or movements of defensive players
• LOTS of inconsistency and error
• Dominant sensory system is vision

The Cognitive Phase (cont.)
• Role of the Coach:
– Clearly communicate critical aspects of the
skill through verbal instructions, visual
demonstrations, and feedback
• Duration of the Cognitive Phase:
– A few minutes or longer – depends on the
athletes age and the complexity of the skill

The Associative Phase
• Refining the skill:
• Goal is to perform the skill both accurately and consistently
• Movement becomes more automated and
proprioceptive – athlete relies on visual control less
and less
• Athlete uses sensory feedback to evaluate movement
correctness, also develops the capability to generate
strategies for skill correction

The Associative Phase (cont.)
Role of the Coach:
• Design effective practices to optimize skill refinement
so athlete can quickly adapt to performance setting
demands
• Provide a variety of practice experiences and more
feedback
Duration of the Associative Phase:
• Longer than the cognitive phase, ranges from a few
hours to several years

Closed vs. Open Skills
Closed skills:
• Performed in
a stable environment.
• tennis serve
• free throw shooting
• putting in golf
Open skills:
• Performed in a dynamic,
changing environment.
• football punt return
• basketball fast break
• volleyball set or hit

The Autonomous Phase
• Skill performance is at a maximal
level of proficiency
• Requires little conscious thought
or attention to movement – it’s
established in memory
• Excellent understanding of the
skill

The Autonomous Phase (cont.)
• Role of the Coach:
1. Help the athletes maintain their level of skill
2. Motivate the athletes to continue improving
• Error correction and learning process:
Major changes in technique should be handled during the
off-season because it can take awhile to again reach the
autonomous phase.

Practice Considerations
• Deliberate practice:
• Combines tasks of appropriate difficulty, information
feedback, and sufficient opportunities for repetition and
correction of errors
• Not enough on its own…
• Athlete must be motivated to learn
• Practice ≠ perfect
• Must practice with the intent to improve

Practice Methods: Whole vs. Part
• Whole Method:
• Athletes practice activity or skill in its entirety, as a
single unit
• Part Method:
• The athlete practices each component of the
activity or skill separately and then combines the
parts into a whole skill

Practice Methods: Whole vs. Part (cont.)
• Progressive-part method:
• The first two parts of a skill are practiced separately and
then combined and practiced as a unit . The third part is
practiced separately next and then combined with the
first two, and so on until the skill is performed in its
entirety.
• Repetitive-Part method:
• First part of the skill is practiced independently. Once a
level of proficiency is obtained, the second is
immediately added to it and the two parts are practiced
together. The pattern continues until all parts have been
integrated.

Practice Methods: Whole vs. Part (cont.)
• Which method you use depends on the nature of the
skill and the nature of the learner.

Practice Methods: Blocked vs. Random
• Blocked Practice
• All trials of a given task are completed before moving on to
the next task
• Random Practice
• Trials for a given task are mixed with other tasks in a
random order

Practice Methods: Blocked vs. Random
(cont.)
EXAMPLE:
Swimmers need to learn the
four strokes in 2 weeks, or 8
practices.
BLOCKED
Practice each stroke for 2
sessions. Swimmers can
concentrate on one stroke at
a time without worrying
about interference from the
other strokes.
RANDOM
Practice all 4 strokes within
each practice period but to
do so in a random order so
that the swimmers never
practice the same stroke on
two consecutive trials.

Practice Methods: Blocked vs. Random (cont.)
• Blocked practice
long-term learning
better acquisition, but poorer
• Measured by transfer:
• The application of practiced skill in a new situation
• Contextual interference effect:
• Making practice environment more difficult (AKA random
practice) leads to better learning, though performance is
depressed

Practice Methods: Blocked vs. Random (cont.)
• During the initial stage of skill acquisition, blocked
practice conditions may be more beneficial
• However, once the basics are acquired, contextual
interference must be increased
• Solution = Repeated blocked practice:
• Combines the advantages of blocked and random

Practice Methods: Constant vs. Variable
Practice
• Constant Conditions:
• Maintaining constant environmental
conditions so the player may put all of
their focus on the task at hand
• Variable Conditions:
• Changing environmental variables in order
to force the athletes to adapt to new
demands

Practice Methods: Constant vs. Variable
Practice (cont.)
EXAMPLE: Practice fielding a
ground ball and throwing to
first base
CONSTANT
100 ground balls thrown by a
pitching machine…constant
velocity, same spot on the
field, same bounce and roll
characteristics; can master
the fundamentals of fielding.
VARIABLE
100 ground balls hit by a
batter…different bounce and
roll characteristics, different
spots on the field; forces
player to move and adapt to
the ever-changing demands.

Improving Performance
• Error Identification and Diagnosis
–Analyzing the skill:
1. Compare athlete technique to
correct technique
2. Determine the cause of the
error(s)
– Technique, physiological
deficiencies,
inaccurate/delayed decision
making, drill design,
psychological factors
3. Select which error to correct –
only one at a time!

Feedback as an Intervention Strategy
• Shapes a learner’s efforts to achieve the task
goal
–Can reinforce a behavior
–Provide information about the correctness of a
performance attempt
–Explain why an error occurred
–Prescribe how to fix an error and motivate athletes
to continue working towards their goals
• Must consider the frequency, timing, amount,
precision, and the learner’s task related
experiences

Feedback (cont.)
• Feedback frequency
• Faded feedback: feedback is gradually reduced as
the athletes’ skills increase
• Bandwidth feedback: feedback only provided when
athlete’s performance falls outside a range of
acceptable error tolerance
• Learner-regulated feedback: feedback only
provided when the athlete requests it

Feedback (cont.)
• Choose words carefully
• One correction at a time
• Positive
• Short and Simple
• Matches the learner’s developmental level
• Use specifics

More Intervention Strategies
• Manipulating Task and/or Practice Variables
• Creates action possibilities that allow for the emergence of improved
techniques and/or tactics by capitalizing on the process of guided
discovery
