1 - Sensorimotor Control Introduction Flashcards
def: includes individual movements and motor skills
motor behaviour
def: a goal directed task that requires voluntary head, body, and/or limb movement, made up of a series of movements
motor skill
def: make up the components of a motor skill and are defined by the behavioural characteristics of the limb or a combination of limbs
movement
def: uses sensory information prior to the execution of movement rather than during the movement
feedforward control
def: uses sensory information during the execution of movement
feedback control
def: postural changes that occur prior to the onset of the postural disturbance due to self-movement
APA’s, anticipatory postural adjustments
def: to move the eyes as quickly as possible to shift the fovea to a visual target in the periphery
saccade
def: keeps image of moving target on fovea
smooth pursuit
def: invloluntary coordinated stereotyped patterns of muscle contraction and relaxation elicited by peripheral stimuli
reflexive motor behaviour
def: repetitive, can occur spontaneously or triggered by peripheral stimuli
rhythmic
def: goal-directed movements that improve with practice as a result of feedback and feedforward mechanisms
voluntary
def: experimenter produced actions of the target and participant’s own movements are both displayed
pursuit tracking
def: experimenter produced variations in the track are combined with participant’s movements to control a single cursor on a screen; participants must maintain this target value at some location
compensatory tracking
def: path or target “jumps” from one location to another as participant is performing a motor behaviour; participant must correct and move to the new location
step tracking
