Q

________________ is the reaction time is a variation of choice reaction time, the situation involves more than one signal and each signal requires its own specified response, BUT the order of the stimuli is sequential.

A

Serial reaction time

22
Q

____________ is the unsigned deviation from the target or criterion, representing amount of error. A measure of the magnitude of an error without regard to the direction of the deviation

A

Absolute error

23
Q

____________ is the signed (+/-) deviation from the target or criterion; it
represents amount and direction of error and serves as a measure of performance bias

A

Constant Error

24
Q

____________ is an error score representing the variability (or consistency) of
performance

A

Variable Error

25
Q

___________ is the difference between the actual performance and the action goal of a SINGLE attempt.

A

Plain Error

26
Q

_____________ is a kinematic measure describing changes in the spatial positions of a limb or joint during the time course of the movement

A

Displacement

27
Q

____________ is 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 (speed)

A

Velocity

28
Q

_____________ is a kinematic measure that describes change in velocity during movement; we derive it from velocity by dividing change in velocity by change in time

A

Acceleration

29
Q

_____________ is about location; the difference between where it started and where it ended. The dista.nce (in a straight line, not following roads) from your house to school

A

Displacement

30
Q

__________ is the speed at which it moved. The speed you were driving on your way to school.

A

Velocity

31
Q

___________ is how fast it sped up or slowed down. The speed in which you sped up to enter 1604 traffic.

A

Acceleration

32
Q

A

EEG (electroencephalography)

33
Q

___ measure brain activity by showing blood flow and metabolic activities in the brain with the use of a radioactive solution

A

PET (positron emission topography)

34
Q

___ measures muscle activity using either surface electrode or the insertion of fine wire electrodes into the muscle

A

EMG (electromyography)

35
Q

___ measures brain activity by detecting blood oxygenation in the brain while a person is performing a skill or activity

A

fMRI (functional magnetic resonance imaging)

36
Q

An ________ is a general trait or capacity of a person that is determinant of a person’s achievement potential for the performance of specific skills

A

ability

37
Q

________________ maintains that although many different motor abilities can be identified within an individual they are highly related and can be characterized in terms of singular and global motor ability. The hypothesis predicts that if a person is highly skilled in one motor skill then he or she would be expected to be skilled in all motor skills.

A

General motor hypothesis

38
Q

Researchers say that _______ _______

A

dynamic balance

39
Q

A

parietal

46
Q

Know about the area of the cerebral cortex that’s primarily responsible for organizing movements BEFORE they are initiated

A

Premotor area of the cerebral cortex

47
Q

___________ _________ is a basal ganglia disorder caused by the lack of production
of the neurotransmitter dopamine by the substantia nigra
It is characterized by clow movements (bradykinesia), a reduced amount of movement (akinesia), tremor, and muscular rigidity

A

Parkinson’s Disease

48
Q

_______ ________ the ultimate end of the transmission of motor neural information and is made up of the alpha motor neuron and all the muscle fibers it innervates.

A

Motor Unit

49
Q

____________________ is a control problem that occurs in the designing of complex system that must produce a specific result

A

affordance concept

51
Q

the ratio of leg length to stair height determines whether a set of stairs is climbable; someone with short legs would only be able to take small steps or one step at a time, but someone with very long legs would be able to take large steps or multiple small steps with each stride
