Document Summary

Measuring motor behaviour: the performance outcomes, describing the movement, measuring the activity of the cns during the movement. Reaction time: reaction time is very important - how ef ciently someone can perform a motor skill, de nition: interval time between the onset of a stimulus and the initiation of a response. In neurosciences, the most widely used task is the button pressing task. Participant will press a button in response to an auditory, visual, etc. stimulus. Types of reaction times: srt - simple reaction time. Short intervals because they can be mediated sub- cortically: crt - choice reaction time. Increasing # of stimulus response alternatives (sr) then you get a choice reaction time. Importantly, you don"t know which light will come on, so you don"t know ahead of time which nger will be pressing the button. Any light could come on, but you only press a button if the red light goes on.
