Document Summary

Motor skills can be "classified" under; used in rehab and clinical sciences: task organization, discrete skill. Action is usually brief and has a beginning and an end that is distinct: serial skill. Serial discrete actions, combination of various discrete actions. Order of actions is critical to performance success: continuous skill. Topic 5: measurement, interpretation and evaluation of motor skill performance. Measuring motor behaviour: performance outcome, behavioural findings, really important. Foreperiod: difference in time between warning signal and go signal (should be randomized to prevent premeditation) = good rt measure. Fractionation of reaction time: premotor rt, period of time between onset of stimulus and beginning of muscle activity, measured with emg. Measures top-down sensory and cognitive processes: alzheimer"s patients have long premotor rt, upper motor neuron injury, motor rt, period of time between onset of muscle activity and observable movement (movement of extrafusal muscle fibers)
