Flashcards in 8 - Information processing Deck (29):
Describe the input stage of information processing, and where the information if coming from.
Seeing/ hearing/ feeling all the things that are going on around . It could be coming from the crowd, the opponents etc. Where the inflammation is coming from is called the display. (The environment that provides all the information)
What is selective attention?
When you focus on the relevant information from the display.
Describe the perception part of information processing.
The process if acquiring, interpreting, selecting and organising sensory information.
What is proprioception, and its components?
Body awareness, it has 3 components, touch, equilibrium, kinaesthesis.
Describe the components of proprioception
Touch - Detects pain, pressure, temperature.
Equilibrium - Balance, tipping turning
Kinesthesis - a sense that tells the brain about the movement of the muscles, tendons and joints
What is the DCR process?
Detection - the process of the registering of the stimuli by the sense organ
Comparison - the process of referring the stimulus to the memory to compare it to previously stores stimuli
Recognition- the process of finding corresponding stimuli in the memory
Name the 3 memory stores
Short term sensory store (STSS)
Short term memory (STM)
Long term memory (LTM)
What are the processes within the memory and describe them
Encoding - storing new information by repeating it
Maintenance - keeping it 'alive'
Retrieval - finding coded information
Describe the short term memory
Hold information for 60 seconds
Holds 5-9 pieces
If the information isn't needed its is replaced in 30 seconds
Holds information from the STSS that is important
Retrieves info from LTM to perform movement
What are ways to improve short term memory?
Chunking - storing groups of information as one piece
Chaining - simplifying actions into smaller links
How should a coach make sure information has gone into the short term memory?
To the point
Make sure attention is being given
What influences the retention and retrieval of information shorted in the long term memory?
Speed of learning (quicker is better)
Overlearning the skill
Describe the long term memory
Short term memories are either stores in long term memory or lost
Can be stored for years possibly forever
What are the strategies to improve memory?
Chaining - simplifying an action by reducing it into smaller links in a chain of events
Mental rehearsal - 'running through' a performance in your mind
How do you make mental rehearsal effective?
Create a mental image using all the sense
See yourself through your 'minds eye'
Evaluate the movements and consequences
What is select response/ response selection?
Deciding how to respond
Choosing a motor programme
What is reaction time (in memory)
The time to make a decision
What is movement time?
The time from the start of the response to the end
What is response time and how do you calculate it?
The time from the start f the stimulus to the end of the response.
Reaction time + movement time
What is choice reaction time?
The time taken between stimulus and action that requires a choice
EG) in basketball deciding whether to pass or dribble
What is simple reaction time?
The time taken to start a single response to a single stimulus
What is Hicks Law?
The theory that the more choices there are the slower the reaction time will be
What is temporal anticipation?
A performer guesses what is about to happen
What is spatial anticipation?
When a player guesses a movement will be needed
Describe the psychological refractory period
This is when sports performers use dummy's/fakes.
The opposition sees the player move one way so the brain processes this and moves to block them. While the brain is processing it the player dodges in the other direction. Although the brain has picked up the second stimulus it has to finish processing the first (the dummy) before being able to process the actual movement
What are motor programmes?
A series of muscle contractions that produce a movement, that is stored in the LTM
What are subroutines?
Separate movements that make up a whole skill
How to improve selective attention?
Make the stimulus more intense
Expressions like 'watch the ball', 'look when I place my feet'
Repetition with various distraction
