EXSS 380 EXAM 2 PRACTICE QUESTIONS
For a simple reaction time experiment, subjects must perform two different tasks in
response to the same stimulus. The first task (Task 1) involves flexing the elbow as
quickly as possible. The second task (Task 2) involves flexing the elbow as quickly as
possible and then making contact with a suspended tennis ball. For which task would
we expect a longer reaction time?
a.Task 1
b. Task 2
c. Both should display the same reaction time - Answers :Task 2
All are examples of declarative memory except ___
a.Remembering your locker combination
b.Knowing that the rubber on the pitcher mound is 60'6'' from home plate
c.How to move your hand to sign your name with a pencil
d.Knowing the word for "house" in Spanish - Answers :c.How to move your hand to sign
your name with a pencil

c.Inability to make small changes in movement due to error
d.Inability to increase gait velocity - Answers :c.Inability to make small changes in
movement due to error
Variability can be thought of as a positive way to manage degrees of freedom and
variability allows for multiple strategies to be used to achieve a goal.
a.True
b.False - Answers :a.True
Of the following examples, which best describes a change in parameters of a motor
