8. Stages of Information
Processing (Schmidt 2000)
• Stimuli are detected by our senses
• Proprioceptive information - Touch, equilibrium, kinaesthesis
Stimulus
(Input)
• Patterns of movement are detected and processed (perceptual
processes – Detection, Comparison and Recognition)Stimulus Identification
• Decide which movement to make.
• Concentrate on the stimuli that are important – Selective attentionResponse Selection
• Messages are sent via the nerves to the muscles to carry out the
required movement

16. MEMORY
 Memory is important for
information processing,
particularly when we rely on
our previous experiences
 It is important in determining
the motor programme chosen
to send information to the
muscles
 Memory can be divided into
three components:
Short
Term
Sensory
Store
STSS
Short
term
Memory
STM
Long
Term
Memory
LTM

17. Short Term Sensory Store
 All stimuli enter the STSS but remain for a very short time; 0.25 –
1 second
 The STSS has a very large capacity
 It acts as a filter
 The perceptual mechanism determines which information is
relevant and attention is focused towards this. This is the
recognition aspect of perception
 Irrelevant information is filtered out, leaves the STSS and is
quickly replaced by new information
 The filtering process is known as selective attention
 The process of focussing on the important and ignoring the
irrelevant also helps us to react quickly
 It is, therefore, very important to be able to recognise relevant
cues

18. TASK
 Kim’s Game

19. Short term memory
 Referred to as the ‘work place’
 Incoming information is compared to that stored in the ltm
 Has a limited capacity: 5 – 9 pieces of information for approximately 30
seconds
 The number of items can be increased by ‘chunking’
 The period of time can be extended by repeating/ rehearsing the
information
 Information considered important is rehearsed or practised and passed to
the long term memory – this process is known as ‘encoding’

20. SSTS
-improving efficiency
 EXPERIENCE – an experienced volleyballer knows which cues to look
for when blocking
 AROUSAL – the more alert you are the more likely you are to select
relevant cues, e.g.. In tennis an alert player is more likely to notice the
speed, spin and direction of the ball
 QUALITY OF INSTRUCTION – beginners do not know which cues are
relevant. Teachers/ coaches can direct attention to the correct cues
 INTENSITY OF STIMULUS – the effectiveness of the senses when
detecting speed, sound, size, shape, colour etc.

21. LONG TERM MEMORY
 Holds information that has been well learned and practised
 Its capacity is thought to be limitless
 Information is held for a long time – perhaps permanently
 Motor programmes are stored in the LTM as a result of practice –
this is why you never forget how to swim or ride a bike even if you
have not done so for a long time.
 The LTM is the recognition part of the perceptual process when
the stored information in the LTM is retrieved and compared to
the new information which is then recognised

22. Task – Experiment – In pairs
 1 person writes down 7 four-letter nonsense
words made up of consonants e.g. grtp
 Allow your partner to view the words for 10
seconds
 See how many she/he can remember (record)
 If you partner fails to remember all words – let
them have another go and record
 Repeat experiment with 7 words related to
sport (also four letters e.g. Ball). Is there a
difference? If there is why do you think this is?

23. Strategies to improve retention and
retrieval
 REHEARSAL/ PRACTICE –carries the skill to
and fro between the STM and LTM
establishing a memory trace. Elite performers
practice their skills until they have been ‘over
learned’ / ‘grooved’ and become automatic
 ASSOCIATION/ LINKING – new information
should be linked with that previously learned
e.g. Sports specific skills linked with
fundamental motor skills – javelin throw linked
with overarm throw
 SIMPLICITY – new information should be
kept simple, more complex information can be
added later. Avoid teaching similar skills at
the same time as may interfere with each
other.
 ORGANISATION – A trampoline sequence
should be learned in the order movements will
be performed
 IMAGERY –mental picture aids memory.
Demonstrating skills allows a performer to
create an image of the movement
 MEANINGFUL – if the learner considers
information relevant it is more likely to be
remembered
 CHUNKING – items of information are more
easily remembered if grouped together
 UNIQUENESS – if information is presented
in an unusual or different way it is more
likely to be remembered
 ENJOYMENT – if the learner is having fun
the experience is more likely to be
remembered
 POSITIVE REINFORCEMENT – praise and
encouragement when learning can aid
retention. This can also be motivational and
includes rewards such as badges and
certificates

27. Exam Qs
4. (a) During practice for sport, describe
two strategies that could be used to
improve the longterm memory. [4]

28. Answers

29. Learning Objectives
 Be able to name the 3 components of memory
 Be able to describe at least 3 features of each
component of memory
 Be able to explain how you can use at least 2
strategies to improve memory applied to a
sporting situation

30. Learning Objectives
 Be able to define reaction time, response
time and movement time and explain the
relationship between these terms
 Be able to apply a sporting example to
these terms.
 Be able to explain Hick’s law
 Be able to demonstrate how the single
channel hypothesis can be used to a
sports persons advantage

31. Reaction Time
 Reaction Time
 Movement Time
 Response Time
 How are they linked?
REACTION TIME + MOVEMENT TIME =
RESPONSE TIME

32. 100m race
• 0.2 seconds to react to the gun,
• 12 seconds to run the race,
• Total response time of 12.2 seconds
Tennis Serve
• See serve going to your left and deciding to go that way takes about 0.2
seconds,
• Moving to intercept and play the return shot takes a further 0.3 seconds
• Total response time of 0.5 seconds

33. Little experiment……..
 Time your partner organising the cards in
to the following sets:
 Colours (Red and black)
 In to suites (Diamonds, Clubs, Hearts,
Spades)
 In to suites and in order (Ace, 2, 3…..Jack,
King, Queen)
 Discuss why there was difference in
response time.

34. Types of Reaction Time
 Simple - One stimulus with only one
correct response e.g. reacting to a
starters gun by beginning to run
down the track towards the finish
 Choice - Either, several stimuli, which
may have any number of possible
responses
 Or, one stimuli with a number of
possible responses

35. Hick’s Law
 The more stimuli that there are, the
longer it will take to choose the correct
response
 Hick’s Law (1952) “Choice reaction time
is related to the amount of information
that must be processed to resolve
uncertainty about the various possible
stimulus response alternatives”

36. Strategies – shortages of time
Anticipation
Fake – how does this
work?
