Exam 2: The Measurement of Motor Performance

This error measure evaluates overall accuracy during a series of trials.

Force can be calculated from the kinematics of a movement if you know the mass of the moving object and the ________ of the movement.

This brain activity measurement technique realigns hydrogen atoms in the body and may provide clear 2D and 3D images of the brain.

An individual must respond to only one of several signals presented in this type of reaction time.

Simple RT involves one signal and more than one possible response.

EEG recordings will show __________ waves when the cerebral cortex is active.

If you want to describe the movement of an object in a straight line, the type of motion you would describe is referred to as ________.

The calculation of ______________ provides an objective measure of the coordination between two limbs or limb segments by comparing the specific location of each limb or limb segment in one cycle of a cyclic movement.

Constant error (CE) refers to a person's performance bias during a series of trials.

TMS involves directing a short burst of magnetic waves at a specific area of the brain cortex in order to temporarily activate that area.

This error measure evaluates performance consistency during a series of trials.
