Topic 5 Skill in Sport
Terms in this set (15)
Label the simple model of information processing
1. take information from our environment (
2. make a
3. produce a response (
4. see/hear/feel what happens (
Label Welford's model of information processing
1. Inputs seen as relevant are stored in the short-term memory.
2. Information compared with previous experiences stored in the long-term memory.
3. Action and results stored for future reference
Outline the components associated with sensory input
exteroceptors, proprioceptors, introceptors
Sensory perception #1: What are interoceptors? give examples of what they do.
Interoceptors (or visceroceptors) provide information about the body e.g., blood pressure, blood glucose concentration, bladder.
Sensory perception #2: Explain exteroceptors. Give examples.
Exteroceptors provide information about the external environment e.g. touch, pressure, temperature, light, sound, taste, smell. (
Sensory perception #3: Explain proprioceptors.
Proprioceptors provide information about the position and posture of our body in space.
1. What is the signal detection process? (SDR)
2. Name 2 things that will impact on the efficiency of the signal detection process.
1. Brain separates important information from
to the signal ('d-prime') based on experience.
. We can miss signals or find signals when they don't even exist.
Distinguish between sensory information store, short-term memory and long-term memory.
1. sensory information store: 0.5 seconds; important information (see SDR) passed to STM.
2. Short-term memory: lost within 10 seconds; rehearsed and passed to LTM
3. Long-term memory (LTM): no capacity limitation.
Explain the concept of 'selective attention'
Short-term memory has limited capacity (7 items) so we need to chose what we focus on.
Name 4 different methods of memory improvement
• association (mnemonics)
• visualization (images better than words)
Define response time
Response time= reaction time + movement time
3 factors that impact on response time
• number of choices (ways we could respond)
What is a motor programme?
Explain the difference between sub-routines and an executive programme.
• Motor programme: a set of movements stored in the memory as a whole e.g. catching a ball.
• Gymnasts can learn
(hand stand, back-flip) and build them into a single
e* (floor routine)
Feedback: what's the difference between extrinsic feedback and intrinsic feedback?
• Intrinsic feedback: We can see the result of our actions (dart-payer) and feel how our body moves (shot at goal).
• Extrinsic feedback: information provided by a coach or videotape.
Feedback: which is better feedback a) "great shot! Do that some more" or b) "your right arm was stretched horizontal when you played the shot"
B is better feedback because it is
. B helps us to take control and improve our performance.
A is motivational but gives us no data. We are not sure what we were doing and can only guess.
