Shooting a free throw in basketball is an example of an open motor skill.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
Shooting a free throw in basketball is actually an example of a closed motor skill, not an open motor skill. Closed motor skills are those that are performed in a predictable and stable environment, where the performer has control over the execution of the skill. In the case of shooting a free throw, the environment is relatively stable and the shooter has control over their movements and execution. Open motor skills, on the other hand, are performed in a dynamic and unpredictable environment, where the performer must react and adapt to changing conditions.Rate this question:

- A.
Discrete motor skill
- B.
Fine motor skill
- C.
Gross motor skill
- D.
Open motor skill
Correct Answer
C. Gross motor skillExplanation
A gross motor skill involves the use of large muscle groups and does not require precision of movement for successful performance. This means that the skill requires the coordination and control of larger body parts, such as the arms, legs, or torso, rather than fine movements that require precise control of smaller muscles. Examples of gross motor skills include running, jumping, or throwing a ball. Therefore, the given correct answer, "Gross motor skill," accurately describes a motor skill that fits the given criteria.Rate this question:

Research has demonstrated that reaction time (RT) and movement time (MT) are
- A.
Independent motor abilities
- B.
Moderately related motor abilities
- C.
Highly related motor abilities
- D.
None of these
Correct Answer
A. Independent motor abilitiesExplanation
The research suggests that reaction time (RT) and movement time (MT) are independent motor abilities. This means that they are not strongly related to each other and can be considered as separate skills. This implies that an individual's performance in one of these abilities does not necessarily predict their performance in the other.Rate this question:

Parkinson’s disease is the result of a dysfunction of which area of the brain?
- A.
Basal ganglia
- B.
Cerebellum
- C.
Cerebral cortex
- D.
Diencephalons
Correct Answer
A. Basal gangliaExplanation
Parkinson's disease is caused by a dysfunction in the basal ganglia, which is a group of structures located deep within the brain. The basal ganglia play a crucial role in regulating movement and motor control. In Parkinson's disease, the neurons in the basal ganglia degenerate and produce less dopamine, a neurotransmitter involved in movement. This leads to the characteristic symptoms of Parkinson's disease, such as tremors, rigidity, and difficulty with coordination and balance. Dysfunction in other areas of the brain, such as the cerebellum, cerebral cortex, or diencephalon, may contribute to other neurological disorders, but they are not primarily responsible for Parkinson's disease.Rate this question:

- B.
Association cortex
- C.
Motor cortex
- D.
Sensorimotor complex
Correct Answer
B. Association cortexExplanation
The association cortex is commonly considered to be the location for the transition between the perception of sensory information and the resulting action. This is because the association cortex is responsible for integrating and processing information from various sensory areas, and it plays a crucial role in higher-order cognitive functions such as perception, attention, memory, and decision-making. It receives input from the sensory cortex and sends output to the motor cortex, which then initiates the appropriate motor response.Rate this question:

Which of the following is not a part of a motor unit?
- A.
Muscle fiber
- B.
Dendrite
- C.
Interneuron
- D.
Axon
- E.
Motorneuron
Correct Answer
C. InterneuronExplanation
An interneuron is not a part of a motor unit. A motor unit consists of a motor neuron and the muscle fibers it innervates. The motor neuron sends signals from the central nervous system to the muscle fibers, causing them to contract. The dendrite and axon are both components of a motor neuron, while the muscle fiber is the target of the motor neuron's signals. However, an interneuron is a type of neuron that connects sensory and motor neurons within the central nervous system, and it is not directly involved in the activation of muscle contraction.Rate this question:

An important difference between the open- and closed-loop control systems is that the
- A.
Open-loop system involves feedback; the closed-loop system does not.
- B.
Closed-loop system involves movement commands; the open-loop system doesn't
- C.
Open-loop system involves movement commands; the closed-loop system doesn't
- D.
Closed-loop system involves feedback; the open-loop system does not.
Correct Answer
D. Closed-loop system involves feedback; the open-loop system does not.Explanation
In a closed-loop control system, feedback is used to continuously monitor the output and make adjustments to the input in order to maintain a desired output. This feedback allows the system to respond to changes and disturbances, ensuring accurate and precise control. On the other hand, an open-loop control system does not use feedback and relies solely on predetermined input commands. This means that an open-loop system cannot make adjustments based on the actual output, making it less accurate and more susceptible to disturbances. Therefore, the statement that "closed-loop system involves feedback; the open-loop system does not" accurately describes the difference between the two control systems.Rate this question:

Which of the following types of motor control theories emphasizes the role of a memory representation in the control of coordinated action?
- A.
Dynamic pattern theories
- B.
Motor program theories
- C.
Chaos theories
- D.
All of these
Correct Answer
B. Motor program theoriesExplanation
Motor program theories emphasize the role of a memory representation in the control of coordinated action. These theories propose that movements are controlled by pre-structured motor programs stored in memory, which can be executed automatically without the need for constant feedback. This memory representation allows for the execution of complex and coordinated movements, such as playing a musical instrument or typing on a keyboard, without the need to consciously plan and control each individual movement.Rate this question:

According to Schmidt’s motor program-based theory of motor control, which of the following would be controlled by the same generalized motor program (GMP)?
- A.
Using either hand to reach for and grasp an object
- B.
Hitting a golf ball and hitting a pitched baseball
- C.
Throwing a ball overhand and underhand
- D.
Walking and running
Correct Answer
A. Using either hand to reach for and grasp an objectExplanation
According to Schmidt's motor program-based theory of motor control, using either hand to reach for and grasp an object would be controlled by the same generalized motor program (GMP). This theory suggests that certain motor programs can be generalized and applied to different movements that share similar characteristics. In this case, reaching for and grasping an object with either hand involves similar movement patterns and coordination, making them controlled by the same GMP.Rate this question:

Why is binocular vision superior to monocular vision for perceiving distance to objects and the size of objects?
- A.
Central vision is more precise than peripheral vision
- B.
Binoculars improve vision at distances
- C.
Having two views aids depth perception
- D.
Two eyes are better than one
- E.
A and B
Correct Answer
C. Having two views aids depth perceptionExplanation
Having two views aids depth perception because when we use both eyes to view an object, each eye receives a slightly different image. The brain then combines these two images to create a three-dimensional perception of depth. This is known as stereopsis and allows us to accurately perceive the distance to objects and the size of objects in our environment. Central vision being more precise than peripheral vision and binoculars improving vision at distances are not directly related to the advantage of having two views for depth perception.Rate this question:

When you walk across a street, the optical variable tau influences the initiation of your leg movement to step up onto the curb on the basis of the
- A.
Distance you are from the curb
- B.
Amount of time remaining to contact the curb
- C.
Width of the street
- D.
Height of the curb
Correct Answer
B. Amount of time remaining to contact the curbExplanation
The optical variable tau influences the initiation of leg movement to step up onto the curb based on the amount of time remaining to contact the curb. This means that as the time remaining to reach the curb decreases, the leg movement to step up onto the curb is initiated. The optical variable tau provides information about the time to contact an object, and in this case, it helps determine the timing of the leg movement to ensure a successful step onto the curb. The other options, such as distance, width of the street, and height of the curb, may also play a role in the decision-making process but are not specifically mentioned in the explanation.Rate this question:

According to Fitts’ Law, a person’s movement time will be faster for a task with an ID of 6 than for an ID of 3.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
According to Fitts' Law, movement time is determined by the size of the target and the distance to be traveled. The law states that movement time increases as the task difficulty increases, which is measured by the Index of Difficulty (ID). The ID is calculated by taking the logarithm of the distance divided by the target size. In this case, if the ID of the task with 6 is smaller than the ID of the task with 3, it means that the task with 6 has a larger target size or a shorter distance to be traveled, making it easier and faster to complete. Therefore, the given statement is false.Rate this question:

Consider the following performance situation: You are a basketball player guarding an opponent who has the ball. You know that about 80% of the time in this situation the player will move to your right and take a shot. So, you prepare to move in that direction. But, unexpectedly the player moves to your left. Which of the following describes your RT in this situation?
- A.
It is not possible to predict RT without more information about the situation
- B.
RT will be the same as if you had not prepared to move to the right
- C.
RT will be faster than if you had not prepared to move to the right
- D.
RT will be slower than if you had not prepared to move to the right
Correct Answer
D. RT will be slower than if you had not prepared to move to the rightExplanation
In this situation, the basketball player's reaction time (RT) will be slower than if they had not prepared to move to the right. This is because their initial expectation was that the opponent would move to the right and take a shot.

Central pattern generators, which are involved in the control of gait, are thought to be located primarily in the brain.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
Central pattern generators are not primarily located in the brain. They are actually located in the spinal cord and are responsible for generating rhythmic patterns of muscle activity, such as walking or swimming. While the brain does play a role in coordinating and modulating these patterns, the central pattern generators themselves are located in the spinal cord.Rate this question:

For skills that involve a starting signal and require movement as quickly as possible after this signal (e.g., swimming, sprint), the amount of time between the warning and start signal should be
- A.
The same for every start
- B.
Varied for every start
- C.
As constant as possible for every start
- D.
As short as possible for every start
Correct Answer
B. Varied for every startExplanation
For skills that involve a starting signal and require movement as quickly as possible after this signal, it is beneficial to vary the amount of time between the warning and start signal for every start. This variation helps to prevent anticipation and allows athletes to react quickly and explosively to the start signal. By changing the timing, athletes are forced to stay alert and react to the signal in real-time, enhancing their ability to start quickly and effectively. Consistently using the same timing can lead to predictability and a slower start. Therefore, varying the time between the warning and start signal is the best approach.Rate this question:

Which of the following was not a theory discussed in chapter 9 of how attention affects motor performance?
- A.
Bottleneck theories
- B.
Filter theories
- C.
Multiple resource capacity theories
- D.
Central resource capacity theories
- E.
Dual task theories
Correct Answer
E. Dual task theoriesExplanation
The correct answer is Dual task theories. In chapter 9 of how attention affects motor performance, the theories discussed include bottleneck theories, filter theories, multiple resource capacity theories, and central resource capacity theories. However, dual task theories were not discussed in this chapter. These theories typically focus on the idea that attention is a limited resource and that performing multiple tasks simultaneously can lead to a decrease in performance on one or both tasks.Rate this question:

The action effect hypothesis suggests optimal performance results from
- A.
Internal focus of attention
- B.
Increased arousal
- C.
External focus of attention
- D.
Decreased arousal
Correct Answer
C. External focus of attentionExplanation
The action effect hypothesis proposes that optimal performance is achieved when individuals focus their attention externally, rather than internally. This means that instead of focusing on their own movements or body sensations, individuals should direct their attention towards the desired outcome or the effects of their actions. By doing so, they can enhance their performance and improve their ability to execute skilled movements or tasks. This external focus of attention allows individuals to rely on automatic processes and allows for more efficient movement execution.Rate this question:

Studies comparing experts and novices in motor skill performance show that
- A.
Experts have better visual activity
- B.
Experts focus only on certain aspects of the visual cues
- C.
Experts focus better on all of the visual cues in the environment
- D.
Experts are better at tracking fast-moving objects
Correct Answer
B. Experts focus only on certain aspects of the visual cuesExplanation
Experts in motor skill performance have honed their abilities through extensive practice and experience. They have developed the ability to selectively focus on specific aspects of the visual cues relevant to the task at hand. This selective attention allows them to filter out irrelevant information and concentrate on the most important visual cues. By narrowing their focus, experts are able to process and interpret these cues more effectively, leading to improved motor skill performance.Rate this question:

In addition to serving as a temporary storage system, working memory also serves as a
- A.
Procedural knowledge storage location
- B.
Library of information
- C.
Permanent storage system
- D.
Temporary workspace
Correct Answer
D. Temporary workspaceExplanation
Working memory is a cognitive system responsible for temporarily holding and manipulating information needed for complex cognitive tasks. It acts as a temporary workspace where information is actively processed and manipulated. Unlike permanent storage systems such as long-term memory, working memory is not designed for long-term storage but rather for immediate use. It allows us to hold and manipulate information in our minds, making it an essential component of various cognitive processes like problem-solving, decision-making, and learning. Therefore, the term "temporary workspace" accurately describes the role of working memory in our cognitive functioning.Rate this question:

If you are asked to demonstrate how you tie your shoes, you would base your demonstration on knowledge stored in long-term memory in the
- A.
Procedural memory system
- B.
Episodic memory system
- C.
Muscle memory system
- D.
Semantic memory system
Correct Answer
A. Procedural memory systemExplanation
The procedural memory system is responsible for storing knowledge related to skills and procedures, such as tying shoes. When asked to demonstrate how to tie shoes, you would rely on this memory system to recall the step-by-step process and perform the task. This type of memory is often automatic and does not require conscious effort, as it is stored in the motor and sensory areas of the brain.Rate this question:
