B. Sensation of the spatial orientation of body segments
C. Sensation of joint motion
D. Sensation of position in the field of gravity - Answers :C: Sensation of joint motion
2. Whereas a (an) _______ loop system utilizes feedback in the generation of motor
responses, a (an) ________ loop system is preprogrammed in nature.
A. open; closed
B. serial; parallel
C. closed; open
D. parallel; serial - Answers :C: Closed;Open
3. Characteristics of a generalized motor program that can be altered are referred to as
A. invariant features
B. generalized features
C. relative features
D. parameters - Answers :D: Parameters
4. A motor control researcher is conducting a choice reaction time investigation. In
Experiment 1, the subject must lift his/her
index finger off an electronic key, and then flex the shoulder as quickly as possible. In
Experiment 2, the subject must lift the
index finger off the electronic key, and then flex the shoulder as quickly as possible to
bring the index finger to a target. If
the stimulus is the same for both experiments, in which one would we expect a shorter
reaction time?
A. Experiment I
B. Experiment 2
C. Both should display the same reaction time - Answers :A: Experiment 1
5. A motor control researcher asks subjects to perform two tasks. The primary
difference between the two tasks is that one
involves more "movement parts" than the other. Though the stimulus for each task is
identical, and the subjects are aware of
the movement they are to perform, the researcher notices that the reaction time
increased as the number of movement parts
increased. What stage of information processing is most likely influenced by this
experiment?
A. Stimulus identification
B. Response selection
C. Response programming - Answers :C. Response programming
, Rogers: same stimulus throughout
Donders: different stimuli mean different actions, choice is involved
6. According to Donder's Subtractive Theory, which of the following experimental
conditions produces the longest reaction time?
A. Simple reaction time tests
B. Go/No Go reaction time tests
C. Choice reaction time tests - Answers :C. Choice reaction time tests
7. What is denoted by the area between 130 and 300 ms in the figure?

C. Long latency stretch reflex
D. Voluntary activation - Answers :D. Voluntary activation
8. What is denoted by the tallest peak in the figure?
A. Spinal stretch reflex
B. Medium latency reflex
C. Long latency reflex
D. Voluntary activation - Answers :B. Medium latency reflex
9. What sensory neuron is responsible for the initial, small burst of
activity denoted by arrow C in the figure above?
A. Type Ib afferent
B. Type la afferent
C. Type Il afferent
D. Type III afferent - Answers :B. Type la afferent

programs?
