EXSC 525 MODULE 1 QUIZ INTRODUCTION TO
RESEARCH METHODS
TESTED QUESTIONS AND COMPLETE SOLUTIONS
Question 1.
Movement Time (MvT)
ANSWER
time from movement onset to movement end; includes time needed to perform the motor
response
Question 2.
Stratified Randomization
ANSWER
involves random allocation from stratified groups; helps ensure balancing of known factors;
helps prevent selection bias
Question 3.
Premotor Time (PMT)
ANSWER
time from stimulus onset to EMG onset; reflects speed of information processing; depends on
task demands, individual differences, and prior experience
Question 4.
Plateaus
ANSWER
refer to times with little or no improvement
, Question 5.
Open Label
ANSWER
neither subjects nor investigators are blinded
Question 6.
Interim Assessments
ANSWER
MAY be conducted to examine time course of changes
Question 7.
Motor Time (MT)
ANSWER
time from EMG onset to movement onset; reflects time for muscles to initiate movements;
constant amount of time unrelated to processing speed; does NOT depend on tasks demands
or individual differences
Question 8.
Single-Blind
ANSWER
either subjects or investigators are blinded
Question 9.
Simple RT Tasks
ANSWER
one stimulus paired with one response; (response to a start signal)
Question 10.
Dosage
ANSWER
the sum of repetition of motor skills practiced in each session
