Questions and Answers
  • 1. 

    Shooting a free throw in basketball is an example of an open motor skill.

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    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.

    If a motor skill requires the use of large musculature but does not require precision of movement for successful performance, then the skill would best be classified as a

    • A.

      Discrete motor skill

    • B.

      Fine motor skill

    • C.

      Gross motor skill

    • D.

      Open motor skill

    Correct Answer
    C. Gross motor skill
    Explanation
    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:

  • 3. 

    What is the difference between “motor ability” and “skill”?

    • A.

      Motor ability is a personal characteristic; skill is a task

    • B.

      Motor ability is temporary; skill is enduring

    • C.

      Not everyone has skill, but everyone has some motor ability

    • D.

      Skill is temporary; motor ability is enduring

    • E.

      They mean the same thing

    Correct Answer
    A. Motor ability is a personal characteristic; skill is a task
    Explanation
    Motor ability refers to an individual's innate physical attributes and capabilities, such as strength, flexibility, and coordination. It is a personal characteristic that varies from person to person. On the other hand, skill refers to the ability to perform a specific task or activity effectively and efficiently. It involves the application of motor abilities in a specific context or domain. While motor ability is inherent and relatively stable, skill can be acquired and developed through practice and experience. Therefore, the given answer correctly distinguishes between motor ability as a personal characteristic and skill as a task or performance ability.

    Rate this question:

  • 4. 

    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 abilities
    Explanation
    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.

    Explanation
    Returning a serve in tennis is an example of an open motor skill because it involves responding to an unpredictable and constantly changing environment. The player must adjust their movements in real-time based on the speed, trajectory, and spin of the incoming ball. This requires quick decision-making, coordination, and the ability to adapt to the changing conditions of the game.

    Rate this question:

  • 6. 

    Which type of reaction time situation occurs when there are several signals but only one response is to be made to one signal; and other signals are ignored and no response made?

    • A.

      Simple RT

    • B.

      Discrimination RT

    • C.

      Choice RT

    • D.

      Serial RT

    Correct Answer
    B. Discrimination RT
    Explanation
    Discrimination RT refers to a type of reaction time situation where there are multiple signals, but only one response is required for a specific signal, while the other signals are ignored and no response is made. In this scenario, the individual needs to discriminate between the relevant signal and the irrelevant ones, focusing on the specific signal and responding accordingly.

    Rate this question:

  • 7. 

    Reaction time is the interval of time between which two events?

    • A.

      Warning signal and stimulus signal

    • B.

      Stimulus signal and the completion of the response

    • C.

      Stimulus signal and initiation of the response

    • D.

      Warning signal and the initiation of the response

    Correct Answer
    C. Stimulus signal and initiation of the response
    Explanation
    The correct answer is "Stimulus signal and initiation of the response". Reaction time refers to the time it takes for an individual to respond to a stimulus after it has been presented. In this case, the stimulus signal marks the beginning of the reaction time interval, and the initiation of the response marks the end of the interval. Therefore, the correct answer is the interval between the stimulus signal and the initiation of the response.

    In lab 1 we used AE, VE and CE to measure performance in drawing 10cm lines blindfolded. Which of the following would represent a subject who always drew their line short with a high error?

    • A.

      High AE, Low CE, High VE

    • B.

      Low AE, High CE, Low VE

    • C.

      High AE, High CE, Low VE

    • D.

      Low AE, Low CE, High VE

    Correct Answer
    C. High AE, High CE, Low VE
    Explanation
    A subject who always draws their line short with a high error would have a high absolute error (AE) because they consistently deviate from the target length. They would also have a high constant error (CE) because their errors are consistently in the same direction (short). However, they would have a low variable error (VE) because their errors are consistent and not random or unpredictable.

    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 ganglia
    Explanation
    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.

    The area of the cortex that is commonly considered to be the location for the transition between the perception of sensory information and the resulting action is the

    • A.

      Sensory cortex

    • B.

      Association cortex

    • C.

      Motor cortex

    • D.

      Sensorimotor complex

    Correct Answer
    B. Association cortex
    Explanation
    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:

  • 15.

    • A.

      Premotor area

    • B.

      Parietal lobe

    • C.

      Supplementary motor area

    • D.

      Primary motor complex

    Correct Answer
    A. Premotor area
    Explanation
    The premotor area of the cerebral cortex is primarily responsible for organizing movements before they are initiated. This region is involved in planning and coordinating complex motor actions, such as reaching, grasping, and manipulating objects. It receives input from various sensory areas and integrates this information to generate appropriate motor commands. The premotor area also plays a role in motor learning and memory, allowing for the development and refinement of motor skills over time.

    Rate this question:

  • 16. 

    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. Interneuron
    Explanation
    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.

    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.

  • 18. 

    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 theories
    Explanation
    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.

    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 object
    Explanation
    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.

    According to a dynamic pattern view of motor control, skilled action occurs on the basis of action units which

    • A.

      Act according to motor program commands

    • B.

      Receive commands from a control executive

    • C.

      Self organize

    • D.

      Receive feedback as movement occurs

    Correct Answer
    C. Self organize
    Explanation
    According to a dynamic pattern view of motor control, skilled action occurs through the self-organization of action units. This means that instead of being controlled by specific motor program commands or receiving commands from a control executive, skilled actions emerge spontaneously through the interactions and coordination of different action units. This view emphasizes the role of feedback and the ability of the motor system to adapt and adjust movements in real-time based on the ongoing sensory information received during the movement.

    Although researchers have reported various findings, the most reasonable estimate of the amount of time required for visual feedback to enable a movement correction during the performance of a simple manual aiming task is

    • A.

      Between 100 and 160 msec

    • B.

      Between 500 and 560 msec

    • C.

      More than 1000 msec

    • D.

      No time is required; corrections are instantaneous

    Correct Answer
    A. Between 100 and 160 msec
    Explanation
    The most reasonable estimate of the amount of time required for visual feedback to enable a movement correction during a simple manual aiming task is between 100 and 160 msec. This suggests that it takes a short period of time for individuals to visually process information and make the necessary adjustments to their movements. It is not instantaneous, as indicated by the other options, and it is also not as long as 500 and 560 msec or more than 1000 msec.

    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 perception
    Explanation
    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.

    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 curb
    Explanation
    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.

    Fitts’ Law specifies that performance will show a speed-accuracy trade-off in a rapid manual aiming task according to the relationship between which two characteristics of the task?

    • A.

      Distance to move and target size

    • B.

      Distance to move and movement speed

    • C.

      Target size and type of target

    • D.

      Target size and movement speed

    Correct Answer
    A. Distance to move and target size
    Explanation
    Fitts' Law states that the time it takes to complete a rapid manual aiming task is influenced by the distance to move and the target size. According to this law, as the distance to move increases or the target size decreases, the task becomes more difficult and therefore takes longer to complete. This relationship between distance to move and target size determines the speed-accuracy trade-off in the task.

    • B.

      Nerve block

    • C.

      Surgical deafferentation

    • D.

      Sensory neuropathy

    Correct Answer
    A. Tendon vibration
    Explanation
    Tendon vibration is a technique used by researchers to study the role of proprioception in motor control. It involves applying vibrations to the tendons, which leads to a distortion of proprioceptive feedback. However, it does not completely remove proprioceptive feedback. Therefore, tendon vibration is the technique that does not completely remove proprioceptive feedback but only distorts it.

The dominant hand is responsible for strumming or plucking the strings, while the non-dominant hand is used to press down on the frets to change the pitch. This requires coordination and synchronization between the two hands, but they are performing different tasks. Therefore, playing a guitar can be classified as an asymmetric bimanual skill.

    The reason we have difficulty tapping our heads and rubbing our stomachs at the same time with our two hands is that our motor control system is organized in such a way that our two hands prefer to move in the same way at the same time.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    Our motor control system is organized in a way that our two hands prefer to move in the same way at the same time. This means that when we try to tap our heads and rub our stomachs at the same time, our hands tend to synchronize their movements instead of performing different actions simultaneously. This coordination issue makes it difficult for us to perform these two tasks simultaneously, leading to the statement being true.

    The most common performance measure used for inferring the amount of time required for action preparation is

    • A.

      Movement time

    • B.

      Reaction time

    • C.

      Motor time

    • D.

      Response time

    Correct Answer
    B. Reaction time
    Explanation
    The most common performance measure used for inferring the amount of time required for action preparation is reaction time. Reaction time refers to the time it takes for an individual to respond to a stimulus after it is presented. It is often used as an indicator of the efficiency of cognitive and motor processes involved in preparing and initiating a response. By measuring reaction time, researchers can gain insights into the speed and accuracy of information processing, decision-making, and motor planning.

    Hick’s Law states that reaction time (RT) will increase logarithmically as the

    • A.

      Number of response choices increases

    • B.

      Distance required by the movement increases

    • C.

      Movement complexity increases

    • D.

      Arousal level of the individual increases

    Correct Answer
    A. Number of response choices increases
    Explanation
    Hick's Law states that as the number of response choices increases, the reaction time will increase logarithmically. This means that when presented with more options, it takes longer for an individual to make a decision and respond. This is because the brain needs more time to process and analyze the increased amount of information before selecting a response. Therefore, the more choices there are, the longer it will take for someone to react.

    What does an increase in reaction time (RT) mean?

    • A.

      Time to start moving is shorter

    • B.

      Movements are quicker

    • C.

      Time to start moving is longer

    • D.

      Movements are slower

    Correct Answer
    C. Time to start moving is longer
    Explanation
    An increase in reaction time (RT) means that the time it takes for an individual to start moving in response to a stimulus is longer. This indicates that there is a delay in the initiation of movement, suggesting slower processing and response to the stimulus.

    Which of the following will increase reaction time (RT)?

    • A.

      Movement complexity

    • B.

      Repetition

    • C.

      Fewer choices

    • D.

      Foreperiod regularity

    Correct Answer
    A. Movement complexity
    Explanation
    Movement complexity refers to the level of difficulty or intricacy involved in performing a specific movement. When the movement is complex, it requires more cognitive processing and coordination, leading to an increased reaction time. This is because the brain needs more time to analyze and plan the movement, resulting in a delayed response. Therefore, movement complexity can be seen as a factor that increases reaction time.

    “Transport”, “grasp”, and “manipulation” are three components of what?

    • A.

      Impulse-timing

    • B.

      Prehension

    • C.

      Motor equivalence

    • D.

      Dynamic pattern theory

    • E.

      Bimanual coordination

    Correct Answer
    B. Prehension
    Explanation
    The three components mentioned - "transport", "grasp", and "manipulation" - are all related to the act of prehension. Prehension refers to the process of reaching out, grasping an object, and manipulating it. These components are essential in the overall process of prehension, where transport involves moving the hand towards the object, grasp involves the act of holding onto the object, and manipulation involves using the hands to perform specific actions or tasks with the object. Therefore, prehension is the correct answer that encompasses all three components.

    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. False
    Explanation
    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.

    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 right
    Explanation
    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. When the opponent unexpectedly moves to the left, it requires the player to adjust their movement and react in a different direction, causing a delay in their response time.

    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. False
    Explanation
    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.

    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 start
    Explanation
    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.

    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 attention
    Explanation
    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.

    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 cues
    Explanation
    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.

    Explanation
    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.
