ENS 307 Exam #3 Flashcards
Absolute error
amount of error without regard to the sign of the score
Algebraic error
amount of error with regard to the sign of the score (not very accurate)
Variable error
standard deviation of the algebraic error
Reaction time
time between the onset of a stimulus and the first overt response
Kinematics
study of movement w/o regard to force or mass
Kinematic variables
velocity, positional location in space, jerk/angle
Kinetics
study of movement w/ regard to force and mass
Kinetic variables
force, mass
Retention test
retain information over a given period of time, if curve is maintained it is assumed the skill has been learned
Transfer test
if curve is maintained as transfer occurs from one situation to another it is assumed the skill has been learned
Negatively accelerated curve
large to small
Positively accelerated curve
small to large
S-shaped curve
low to high rapidly
Asymptote
a leveling off in performance due to an internal limitation
Ceiling effect
leveling off in performance due to external limitations
Plateau
temporary leveling off in performance followed by additional improvement with practice
Phantom plateau
is not really there if it happens to be there –> something is not right (factors coming into play need to be changed)
Tapering, shaving, peaking
PERIODIZATION
long-term variation of the volume and intensity of training to prevent overtraining and promote optimal performance at the desired time
Mental practice
cognitive rehearsal of a physical skill in the absence of overt physical practice
Internal imagery
experience of expected sensations of the response
External imagery
perspective of an observer as in watching a videotape
Roles of mental practice
skill acquisition (rehabilitation; power training; strategy making) aid in performance preparation
Five Types of Imagery
motivational (specific, general mastery, general arousal)
cognitive (specific, general)
Cognitive theory
when skill high in cognitive components, MP works
Psychoneuromuscular theory
MP creates sub-threshold motor neuron firing that lays down a movement pattern
Overlearning
practice beyond a performance criterion
