2 - Methods to Study Motor Behaviour Flashcards
def: provides the amount and direction of deviation from the target, used for discrete skills
constant error
def: measures the inconsistency or variability in the movement outcome. It is basically the standard deviation of CE, used for discrete skills
variable error
def: measure of overall error, gives indication of the amount of spread of the movement across the duration of the trial/performance, used for continuous skills
root-mean square error
def: quantifies the magnitude of a signal or set of fata
root-mean square
def: time between the onset of a stimulus and onset of a response
reaction time
def: only one response choice available
simple RT tasks
def: multiple response choices are available and/or multiple stimuli may be presented
choice RT tasks
def: interval between the initiation of the response to the completion of the movement
movement time
def: the sum of reaction time and movement time
response time
def: time for central processing
premotor RT
def: used to measure kinetic data
force plates
def: used to quantify kinematic data
motion capture cameras
def: used to record electrical activity from muscles
electromyography (EMG)
def: head mounted mobile systems used to monitor eye movements
eye tracking
def: used to study nervous system activity and function
neuroimaging, neurostimulation
