Jhamesha Bracey Motor Learning and Human PE 522 9/10/2019 performance production measures – a category of motor skill performance measures that indicates their performance or specific aspects of the motor control system during the performance of an action EX: limb kinematics, force, EEG, EMG, etc. reaction time (RT) – the interval of time between the onset of a signal (stimulus) and the initiation of a response EX: the amount of time between the "go" signal for a swimming sprint race start and the beginning of the feet moving off the starting block) relative phase - an index of the coordination between two limb segments or limbs during the performance of a cyclic movement. It is based on calculating the phase angles for each limb segment or limb at a specific point in time and then subtracting one phase angle from the other. Relative phase ranges from 0 (or 360 degrees), which indicates an in-phase relationship between the limb segments or limbs, to 180 degrees, which indicates an antiphase (or out-of-phase) relationship. response time – the interval of time between the onset of a signal (stimulus) and the initiation of a response EX: the amount time between the "go" signal for a swimming sprint race start and the beginning of the feet moving off the starting block) root-mean-squared-error (RMSE) - an error measure used for continuous skills to indicate the amount of error between the performance curve produced and the criterion performance curve for a specific amount of time during which performance is sampled simple RT – the reaction time when the situation involves only one signal (stimulus) that requires only one response. TMS (transcranial magnetic stimulation) - a non-invasive procedure in which a changing magnetic field is used to cause electric current to flow in a small targeted region of the brain via electromagnetic induction. variable error (VE) – the standard deviation of the CE scores; an index of performance consistency velocity – a kinematic measure describing the rate of change of an object's position with respect to time. it is derived by dividing displacement by time (eg. m/sec, km/hr)

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
