By the end of today’s lesson you should be able to…
1. Name at least 3 characteristics of both the short & long term
memory2. Label a diagram showing the
relationship between the components of memory
In pairs write down as many characteristics of the short term
memory that you can think of
You get 1 mark for every point you’ve made that I have on my
list
2 marks if you’ve made a correct point that isn’t on my list!
STM also known as ‘working memory’
STM receives the filtered information from the short term sensory store
STM compares the filtered information with past experiences in
the LTMLimited capacity of approx 7 pieces of
infoInfo can be retained for approx 30
secondsIf the info is practiced / learned it is transferred to the LTM or released
We are going to play a game to see which of you has the best short term
memory• You will be shown a tray with 20 items
• You will have 1 minute to memorise all the items
• The tray will be taken away and you must write down as many of the items
you can remember
• DO NOT DISCUSS WITH ANYONE!!!
Working in pairs
• Pupil 1 makes up a list of 12 random numbers
• They read them out to their partner who must write them down and memorise them in
30 seconds.
• They read them back to their partner without looking at list, who checks if they are correct
• Swap over using a new set of numbers.
How the Short Term Memory can be Improved:
1. CHUNKING
The information is arranged into larger units or ‘chunks’
This allows more information to be stored
E.g. a set play in a game situation will be remembered by a single call /
number
How the Short Term Memory can be Improved:
2. CHAINING
The pieces information are linked together making a chain
Used in the ‘part method’ form of practice
E.g. developing a sequence in gymnastics
How the Short Term Memory can be Improved:
3. SELECTIVE ATTENTION
By using selective attention we are limiting the amount of irrelevant
information passing into the short term memory
Long term memory is the permanent retention of information through
repetition or rehearsal Thought to have an unlimited capacity –
contains vast amounts of information
When performers are faced with a new situation, the relevant stimuli is passed from
the STM- LTM
Comparisons are made with any similar experiences
If recognition occurs, the similarities are noted and a decision made.
If the situation is new, then a motor programme will be formed based on the available
knowledge
This may delay the decision making process
Generally it is thought that once learned and stored in the LTM, skills are protected from
loss – particularly MOTOR skills
How can Long Term Memory be
improved?
Motor programme = plan of action stored in the memory – made up
of subroutines
Sub routines = isolated aspects of a movement
Improving the capability of the
short term memory
Practicing and repeating movements, causing ‘over-learning’ of motor programmes
Using mental
rehearsal
Developing a range of
past experiences
Making info meaningful, relevant &
interesting to the performer
Label the memory model on the next
slide using the words on the side to
help you
•Selective attention
•Long term memory
•Short term sensory store
•Input of stimulus from sensory receptors
•Short term memory
•Motor plan via effector mechanism
A novice and an experienced performer are both playing in
separate rugby matches
Both are confronted with the same situation in their game
They are both in possession of the ball, with support players either side and are confronted with a defender
attempting to make a tackle
Fill in the table on the next slide to highlight and compare the possible memory process of both the novice
and the experienced performer
Novice Performer Experienced Performer
STSS
STM
LTM
Gathers info about some of their own team, opponents,
own position, aware of crowd / coach calling
instructions
Gathers info about their own team, opponents,
personal position
Some relevant stimuli collected e.g. location of
defender and position of 1 support player plus some irrelevant cues e.g. shouts
from crowd about what to do
Eliminates some stimuli e.g. crowd noise – non-option players, retains info about
several possible team-mates and defender’s position
Limited reference data available, distracted by
crowd and either makes pass to closest player or runs into
defender
Large amount of previous experience-can select from range
of options e.g. pass to support player in best position, kick ball
into suitable space or another player
E.G.Playing a tennis game, the
player cannot have experienced every type of
shot, but based on experience they adapt the required stroketo meet the specific situation
In our memory we store generalised series of
movement patterns that we modify to adapt
to the current environment
There are a variety of basic schemas that we
modify which then allow us to develop the skills
needed for specific sports
Running
Jumping
Throwing
Catching
RECALL SCHEMAStarts the movement
Comes from the memory
RECOGNITION SCHEMAControl & evaluate the movement
Feedback is used
Part 1: Knowledge of Initial Conditions
• ‘where are you’
• Location of the performer
• Their environment
• Limb position
E.g. you are behind the line in basketball
about to take a free throw
Part 2: Knowledge of Response Specifications
• ‘what to do’
• About the task to be completed
• Demands of movement
• Height / speed etc
E.g. you are required to shoot the
basketball at the ring
Part 3: Sensory Consequences
• ‘what does the movement feel like’
• Kinaesthetic feeling/sound
& other sensory info etc
• Allows suitable adjustments
to be made
E.g. Feel of the basketball
in your hand as you take the shot
Part 4: Response Outcome
• ‘what happened as a result of the movement’
• end result
• compared to intended outcome
• Vital for updating for
future reference
E.g. was the basketball shot successful
Motor Programme
Feedback
Schema
Example
Passing
Developed from throwing & catching
by experience & feedback
Can be used in
American Football
Netball
Rugby Basketball
Training & Developing
Schema
Variation of Practice
Develop as many schema as possible
Challenging &
progressive tasks
Relevant practice to competitive situation
Avoid blocked practices
So based on Schema theory…how should
sports skills be taught?
Vary conditions by changing initial conditions
Build up a set of
experiences
Use discovery style not command
Teach fundamenta
l skills before sport
specific
For the effective learning of golf skills, the performer needs to remember important
instructions, cues and movement patterns.
(a) What are the characteristics of short term memory? (5 marks)
(b) How can a coach ensure that important information is stored in the performer’s long
term memory? (4 marks)
C) If following schema theory – name 2 ways sports skills such as the golf swing should be
taught (2 marks)Use your notes to help you answer
