skill aquisition Flashcards
information processing
method where data from environment are collected
display and example
sporting environment e.g. crowd
receptor systems
senses that pick up info from the display
5 different senses
sight auditory touch balance kinesthesis
kinesthesis
inner sense that provides info from within the body
proprioceptors
senses that provide internal info from within the body
selective attention
filtering relevant information from irrelevant information
how to develop selective attention
- stimulus made more intense and bright
- improved motivation
benefits of selective attention
- improved reaction time
- correct decision
DCR
detection - picked up relevant info
comparison - match info identified to info already in memory
recognition - use info from memory to identify appropriate response
perceptual mechanism
detects the hose of info picked up by the receptors and ensures it is filtered into relevant and irrelevant information
translatory mechanism
adapting and comparing coded info to memory so decisions can be made
how does translators mechanism work? and example
it uses coded info from perceptual process to pick out an appropriate motor programme
e.g. info on flight of ball compared with image of backhand
effector mechanism
network of nerves that sends coded impulse to muscles so muscles can perform the action
whitings information processing model
input -> receptor systems -> perceptual mechanism -> translators mechanism -> effector mechanism -> muscular system -> output -> feedback data
who developed schema theory?
schmidt 1982
what is schema theory?
when developing a skill core principles can be taken from an existing motor programme and adapted using info from the display and feedback from sense
example of schema theory
javelin and football keeper both use motor programmes made up of sub-routines such as grip, arm action and follow through
define recall schema
initiates movement, comes before the action
2 parts of recall schema
- initial conditions = info from environment (where am i?)
2. response specifications = info from environment is assessed (what do I need to do?)
define recognition schema
controls movement, happens during action
2 parts of recognition schema
- sensory consequences = info about the feel of movement, use senses to help guide the movement
- response outcome = feedback about the result, schema + motor programme updated by knowledge of results
3 things a coach can do when coaching schema?
- varied practice
- frequent feedback to ensure actions and motor programmes can be adjusted
- reinforcement = increased motivation
