Q

MEMORY STORE RELATIONSHIP

Explain STSS (Short term sensory store)

A

‘Fishing Net’ = All info (irrelevant + relevant) from sense organs enter

Info kept for 1 sec.

Selective attention would then occur.

  • Info not selectively attended to is FORGOTTEN

Q

MEMORY STORE RELATIONSHIP

Explain the role of the STM (Short term memory) when performing a skill

A

Receives info from STSS via selective attention.

Receives coded info from LTM

Can retain 5-9 pieces of info at any 1 time. - can be ⬆️. by ‘chunking’. (grouping info).

Approx 30 secs before info is lost

(a.k.a working memory due to where decision making occurs)

If this info is practise or rehearse then it passes to LTM.

Produces action by passing on decisions via body’s effector mechanisms

25
FACTORS AFFECTING MEMORY RETENTION IN A SPORT SETTING Explain avoid interference
Avoid presenting 2 similar bits of info one after the other, allow it time to sink in. i.e long badminton serve, then short badminton serve.
26
FACTORS AFFECTING MEMORY RETENTION IN A SPORT SETTING Explain link
Link new info to old info. Stored in LTM i.e Netball last week we looked at 1/2 landing then throwing, this weeks we change direction before throwing'. ASSOCIATION
27
FACTORS AFFECTING MEMORY RETENTION IN A SPORT SETTING Explain organisation
Organise info in a meaningful way. i.e a gymnast must practise joining moves together when learning a sequence.
28
FACTORS AFFECTING MEMORY RETENTION IN A SPORT SETTING Explain rehearsal
Repeat to remember
29
FACTORS AFFECTING MEMORY RETENTION IN A SPORT SETTING Explain imagery
Create a 'mind picture'. Provide a demonstration so that performer can translate info into an image. i.e in front crawl "reach over the barrel".
30
Besides CALORI, What are the other methods to enhance learning?
Avoid info overload Ensure learner is paying attention Practise after demo Emphasise key points Use rhymes, stories
31
Define reaction Time
Speed with which we process info. One's ability to respond is limited by the speed to which they react to the stimuli
32
Define response time
Reaction time + Movement time == Time from initial stimulus to the completion of the response.
33
Define movement time
Time from the initiation of a response until its completion
34
What are the types of Reaction time?
Simple = 1 stimulus + 1 response Choice = EITHER 1. responding to several stimuli, each requiring a diff. response OR 2. Subject being presented w/ several stimuli + only 1 possible response.
35
Give an example for simple reaction time
reacting to the starter gun
36
Give an example of a choice reaction Time
Reacting to opponent's serve in racquet games, cross court? down the line?
37
What does Hick's law state?
More choices you have = more info you must process = longer reaction time.
38
Define anticipation
Skilled performers draw on past experiences to anticipate what is going to happen + process before the event has happened.
39
What are the types of anticipation
Spatial Temporal
40
Define spatial anticipation
Involves performer attempting to predict what the actions of their opponent will be + formulate a response in readiness.
41
Define temporal anticipation
Attempt by performer to predict when an action of their opponent will take place
42
FACTORS AFFECTING REACTION TIME What individual characteristics affect reaction time
Age Gender Height Health (ill health = slower) Body temp (colder = slower) Fatigue Personality Length of neural pathways
43
FACTORS AFFECTING REACTION TIME Give influences from the demands of the task and the nature of the stimulus
Intensity of stimulus Probability of stimulus occurring Existence of warning signals + extent to which stimulus is expected Sense being used for detection
44
What factors affect reaction time + anticipation?
Implications Previous experiences Stimulus - response capability
45
FACTORS AFFECTING REACTION TIME + ANTICIPATION Explain implications
Team games = lots of stimuli = slow reaction time, esp. in young performers. Skills are best practise in small scale situations, i.e 2 vs 2
46
FACTORS AFFECTING REACTION TIME + ANTICIPATION Explain previous experiences
Reacted to stimuli before = quicker reaction time. Motor programs may run automatically
47
FACTORS AFFECTING REACTION TIME + ANTICIPATION Explain stimulus-response capability
If stimulus + response naturally fit together = quicker reaction time. i.e throw to right, catch with right.
48
What are the ways to improve response times
Detecting the cue Detecting relevant cues Decision making Change in attentional focus Controlling anxiety Creating optimum motivation Warm-up
49
IMPROVING RESPONSE TIMES Explain detecting the cue
Work on sorting out the stimulus (i.e team mates) from the noise (i.e crowd).
50
IMPROVING RESPONSE TIMES Explain detecting relevant cues
Pick out relevant stimulus from other possible ones - choice reaction time reduced by eliminating alternative choices. i.e ignoring sledding in rugby or cricket
51
IMPROVING RESPONSE TIMES Explain decision making
Work on set pieces so that an 'automatic' complex response can be made to a simple stimulus. i.e short corners in hockey
52
IMPROVING RESPONSE TIMES Explain change in attentional focus
Practise a switch of conc. quickly from 1 sit. to another. i.e attack to defence
53
IMPROVING RESPONSE TIMES Explain controlling anxiety
By using calming strategies. i.e deep breathing
54
IMPROVING RESPONSE TIMES Explain creating optimum motivation
By psyching up. i.e +ive self talk
55
IMPROVING RESPONSE TIMES Explain warm-up
Ensure sense organs + nervous system are in opt. state to transmit info + muscles to act on it.
56
What is the single channel hypothesis
When handling stimuli from the env. the brain can only deal w/ 1 stimulus at a time. a.k.a "bottle neck"
57
Describe what is meant by the psychological refractory period
If 2nd stimulus follows closely behind the 1st, reaction time is slowed because of the ⬆️ info processing time needed. It's the delay. 2nd stimulus could be deliberate or accidental.
58
Define a motor programme
Set of movements stored in the memory. Specifies what movements a skill is composed of and in what order they occur.
59
Where are motor programmes retrieved from?
LTM with a single decision
60
Where are motor programmes run?
STM
61
How is a motor programme put into effect?
By the effector mechanism (nerves + muscles serving the limbs in the movement)
62
What does a motor programme consist of?
Subroutines
63
Define executive motor programmes
Series of sub routines organised into the correct sequence in order to perform a movement, displayed as a hierarchal structure. Must have mastered the subroutines to successfully perform an executive programme.
64
How can motor programmes be linked to the stages of learning?
Fitts + Posner suggest that lowest of subroutines are carried out automatically as they have been learned in early stages of life. As performer becomes more skilful, executive programmes become subroutines of larger executive programmes.
65
Give an example of the hierarchy of a motor programme
Full programme = Trampolining routine Motor programmes = Front drops, somersaults... Subroutines = jump, spin, point toes
66
What are the theories of how motor programmes are run and controlled?
Closed loop control theory Open loop control theory Schema theory
67
THEORIES OF HOW MOTOR PROGRAMMES ARE RUN AND CONTROLLED Explain closed loop control theory
Works with simple + slow limb-positioning movements i.e balancing on beam. Emphasises the role of continuous intrinsic feedback. Which is used to modify the movement produced through comparison of the stored memory trace with the on-going perceptual trace.
68
THEORIES OF HOW MOTOR PROGRAMMES ARE RUN AND CONTROLLED What does the closed loop control theory diagram look like?
MOVEMENT CONTROL ---> MOVEMENT COMMANDS---> MOVEMENT EFFECTORS ---> FEEDBACK (and back to movement control.
69
THEORIES OF HOW MOTOR PROGRAMMES ARE RUN AND CONTROLLED Explain open loop control theory
Focuses on all info being sent as a single message for the movement so not able to rely on fb. i.e jumpshot in basketball
70
THEORIES OF HOW MOTOR PROGRAMMES ARE RUN AND CONTROLLED What does the open loop control theory diagram look like?
Movement control ---> Movement commands ---> movement effectors
71
THEORIES OF HOW MOTOR PROGRAMMES ARE RUN AND CONTROLLED Explain schema theory
Challenges open and closed loop control theory. States motor programmes are clustered together + are interchangeable in response to the situation. Used for discrete skills. He suggested that to perform a skill we need 3 things: 1. Generalised Motor Programme 2. Recall Schema 3. Recognition Schema.
72
METHODS IN WHICH COACH CAN IMPROVE THE INFO PROCESSING MODEL How would they improve it through the memory?
Lots of practise Phrases/sayings More exciting + memorable sessions Not moving on too quickly
73
METHODS IN WHICH COACH CAN IMPROVE THE INFO PROCESSING MODEL How would they improve it through decision making?
Vary practise so learners experience range of situations to build up their LTM to enhance decision making
74
METHODS IN WHICH COACH CAN IMPROVE THE INFO PROCESSING MODEL How would they improve it through reaction time?
Practise + give learners info about important cues to watch for
75
What are the main stages of whitings information processing model?
1. Receptor system (sense organs) 2. Perceptual mechanism (involving selective att. + filtering info) 3. Translatory mechanism (Decision making using ST + LTM) 4. Effector mechanism (output messages sent to limbs via nervous system)
