Skill Acquisition - Decision Making

HideShow resource information
What is decision making?
Selecting which response you should use to respond to a certain stimuli.
1 of 32
What are the two types of reaction time?
Simple and choice reaction.
2 of 32
What is a "simple reaction time"?
The reaction to one stimulus.
3 of 32
What is a "choice reaction time"?
When there are a number of stimuli to choose from before we perform.
4 of 32
What's the equation for response time?
Response time = movement time + reaction time
5 of 32
What is response time?
The time it takes from the onset of the stimuli to the end of the movement.
6 of 32
What is movement time?
The time taken from the initiation of the movement to the completion.
7 of 32
What is reaction time?
The time taken from the onset of the stimuli to the initiation of the movement.
8 of 32
What are the four processes in reaction time?
Receiving the information, coding the information, making the decision, and initiating the movement.
9 of 32
What affects reaction time?
Lack of knowledge, intensity, anticipation, age, gender, alcohol, drugs, number of stimuli.
10 of 32
What is Hick's Law?
The more stimuli the performer has to react to, the slower their reaction time.
11 of 32
How can reaction time be improved?
Relevant practice, highlight key cues, mental rehearsal, intensity of the stimuli.
12 of 32
What is the Single Channel Hypothesis?
You can only react to one stimuli at a time, meaning you have to wait for the first one to be processed before processing the second one.
13 of 32
What does PRP stand for?
Psychological Refractory Period
14 of 32
What is the psychological refractory period?
The delay between the processing of two stimuli in close succession.
15 of 32
How can a performer make use of the PRP?
They can use dummies.
16 of 32
What is a dummy?
When a player pretends to go one way, however quickly change direction causing the opponent to process the first direction before going the way of the player.
17 of 32
What must you take into account when performing a dummy?
Make sure they are close together, however not too close otherwise they wont process the first one. It also has to realistic.
18 of 32
What are the two types of anticipation?
Spatial and Temporal
19 of 32
What is Temporal Anticipation?
When a performer knows what is going to happen but not sure when.
20 of 32
What is Spatial Anticipation?
When a performer can predict what is actually happening before it happens.
21 of 32
What is open loop control?
It has a clear beginning and end. Is performed very quickly and allows no room for feedback.
22 of 32
What is a motor programme?
A generalised series of movements stored in the long term memory. They are developed through practice and past experiences.
23 of 32
What are some advantages of motor programmes?
Reaction times are quick. Skills become habitual. One stimulus can trigger an entire programme.
24 of 32
How can we develop motor programmes?
Relevant practice, concentration, motivation, knowledge, sub-routines and feedback.
25 of 32
What's a sub routine?
A sequence of movements which are performed automatically.
26 of 32
What is closed loop control?
It allows feedback, and the detection of errors and correction to maintain the desired goal.
27 of 32
Give an example of open loop control.
Diving.
28 of 32
Give an example of closed loop control.
A football match.
29 of 32
What is selective attention?
Taking in information from the display, discarding all irrelevant information and passing all relevant information into the short term memory.
30 of 32
How can a coach improve selective attention?
Relevant practice, highlighting key cues, improve anticipation, mental rehearsal.
31 of 32
Why does a skill break down?
Unable to identify stimuli, an overload of information, lack of responses, unable to decide on a response.
