Midterm 1 - Unit 2 Lecture 3 Flashcards
Define performance
an observable behaviour
e.g. hitting a ball
define learning
a relatively permanent change in performance as a result of practice or experience
what are the two ways in which Performance can be analyzed
performance production measures
performance outcome measures
what are performance production measures? Provide an example
refers to measuring behaviour (performance) required to achieve goal
(e.g. rifle shooting: holding the rifle and squeezing the trigger is production)
what are performance outcome measures? Provide an example
outcome refers to measuring the goal of performance
(e.g. rifle shooting: accuracy of shot on target is outcome)
in what type of scenario are performance production measures and performance outcome measures
synonymous
e.g., gymnastics, diving, etc.
what are the 5 Methods for Assessing Production
Human Judgement
Video Recording [film, digital]
High Speed Filming and Computer Analysis
Electromyogram (EMG)
Brain Activity Measures
what is human judegement
usually used to assess production.
This is satisfactory up to a point but will be unsatisfactory where high speed complex movements are involved or where there is a need to understand relationships between movements.
what is Video Recording[film, digital]
assists human judgement by slowing down movement and removing memory load (e.g. football game films.)
what is High Speed Filming and Computer Analysis
slows movement down sufficiently so that position (location), velocity, and acceleration of body parts can be calculated.
what is Electromyogram (EMG)
Body movement produced by muscles. EMG measures electrical activity of muscles so that the size and timing of contractions can be analyzed.
what are 2 Brain Activity Measures
EEG: brain waves
(Measures, electrical activity in the brain using small, metal discs (electrodes) attached to the scalp)
fMRI: functional magnetic resonance imaging
Blood flow to active brain areas.
what are the 4 Methods of assessing Outcome
Response magnitude
Reaction time (speed) (RT)
Fractionated Reaction Time (FRT)
Motor time (MOT)
what is response magnitude? provide an example
Refers to absolute size of response.
ex: Number of laps run during track practice.
what is Reaction time (speed) (RT)
Time from appearance of stimulus to beginning of movement
