Document Summary
Distinguish between performance outcome measures and performance process. Use statistics to calculate performance errors measures. Two ways to measure motor performance: performance outcome measures. Measures the outcome or result of performing a motor skill: a li(cid:373)itatio(cid:374) is that this does(cid:374)"t tell you a(cid:374)ythi(cid:374)g a(cid:271)out ho(cid:449) that out(cid:272)o(cid:373)e (cid:449)as achieved, performance process measures. Measures how aspects of the motor control system are functioning during the performance of an action: e. g. , muscles used, joint angles, nervous system activity. Free-write about your favourite motor skill! (1 minute) My personal favourite motor skill would be swimming. How could you measure your writing performance? (think about both outcome and process measures) The time interval between the presentation of a signal and the initiation of a movement: e. g. , ti(cid:373)e (cid:271)et(cid:449)ee(cid:374) a starter"s gu(cid:374) a(cid:374)d i(cid:374)itial for(cid:272)e o(cid:374) the starti(cid:374)g (cid:271)lo(cid:272)ks i(cid:374) sprinting (i) Simple rt: one signal, one response (ii) Choice rt: more than one signal, each with its own response (iii)
