Chapter 5 - Skill Flashcards
5.1, 5.2, 5.3
what is skill?
skill is the consistent production of goal-oriented movements, which are learned and specific to the task
ex. throwing a ball (learned part) as far as possible (goal oriented part)
types of skills
- cognitive:
thinking, strategy, tactics
ex: knowing how to attack when the other team is playing a offensive trap - perceptual (more environment):
using senses to analyse scenario before acting
ex: (golf) reading surface and deciding what shot technique to use - perceptual motor skill (how you react to the environment):
interpreting environmental stimuli and reacting to them through a motor response
ex: when dribbling, knowing where to go, how to attack well
classifying skills (based on distinctiveness):
- discrete - clear start to finish
ex. jumping - serial - multiple discrete skills linked
ex: lay up, receiving a pass -> run,stop,dribble - continuous - continuous flow of the skill - no stop to finish
ex. running
classifying skill (based on environmental stability) :
- open - externally paced with changing environmental conditions
ex. everything in footy - dribbling, corner, shooting - closed - internally paced (only you decide when to do the skill) with predictable environmental conditions
ex. no examples for team sports , archery
(more environmental stability from 1 to 2)
classifying skill (based on interactions) :
- individual - isolation from others
ex. gymnastics, darts - coactive - with others but no direct interference
ex. swimming, racing, horse - interactive - with others and direct interference
ex. any team sport
more interaction from 1 to 3
classifying skill (based on size of muscle):
- fine motor - smaller muscle groups and fine movements
ex. catching a ball - gross motor - large muscle groups
ex. running
what is ability? (3)
- the traits that we are born with
- perceptual and motor attributes, inherited from our parents that enables us to perform skills
- abilities give us the capacity to perform skill
ex. heigh, flexibility
what is technique?
way in which that sport skill is performed
ex. using a specific grip to spin the ball when pitching/bowling
skill = ? + ?
skill = ability + selection of an appropriate technique
what is novice and skilled performer
novice: someone new to the sport
skilled performer: someone more developed and experienced in the sport
7 key factors that affect technique
- consistency
- accuracy
- control
- learned
- efficiency
- fluency
- goal-directed
draw the simple model of information processing and what does it show?
input -> decision making -> output
shows: the more you practice something you learn how to respond appropriately. overtime strengthening the memory trace and make the output better based on the stimulus presented
types of sense receptors
- exteroceptors:
- detect info from outside body
- sight, hearing –> sport
- sense organs - introreceptors:
- detect info from within the body
- touch + pressure = pain
- blood O2%, glucose , blood pressure - proprioreceptors:
- detect and inform central nervous system for body position and limb movements
- location of the body in space
- balance
- internal sensors
ex. kick a ball -> where leg is in relation to space to know when to kick a ball
ex of how info is processed:
- input
ex. seeing the ball being passed to you - decision making:
ex. moving, changing stance, getting the ball - output
ex. moving body, stopping ball
signal detection definition and steps:
Definition: making sense of stimuli by the brain from sense organs
1. detection:
- brain getting the stimuli
- enviromental
- mostly sight/hearing
- extroceptor mostly
2. comparison:
- take stimuli and compare to examples in long term memory to understand stimuli
3. recognition process
- matching the stimuli to a long term memory experience
