Question
1. Reflexes are automatic motor responses in reaction to an internal stimulus.
True
False
2. Motor behavior involves the study of two overlapping themes: motor control and sport psychology.
True
False
3. We can learn new task without physical practice.
True
False
4. A massed practice schedule is best for learning a continuous task.
True
False
5.Experiments conducted in the area of brain plasticity, have found that certain areas of the brain expand as a result of stimulation or movement of a body part, while the nearby areas of noninvolved body parts shrink.
True
False
6. When an individual is guided externally to complete a task, through use of a robotic device, or a therapist, they generally learn the task better than if they had done the movement on their own.
True
False
7. The same motor command will produce different results depending upon the starting position of the limb.
T/F
Explanation / Answer
1. Reflexes are autonomic stereotypic response to external and internal stimuli. It is an automatic involuntary behavior occurs in the same way each time. It does not require prior experience. Reflex arcs have sensory and motor neurons. For example, when a hot object is touched by an arm, the arm is jerked involuntarily. The stimulus activates the pain receptors in the skin, which activates the sensory neuron. The impulse transports to the spinal cord where it passes to a relay neuron. The relay neuron transmits the message to the motor neuron, which transmits the response to the muscle.
Option is True.
2. Motor behavior is study of human action and behavior. It involves two overlapping themes, motor control and motor learning. Motor control studies the underlying processes that affect the production of movement in health and disease. Motor learning studies the mechanism by which skilled movements are acquired.
Right option is False.
3. New skills can be learned without physical practice. This is done by practicing the skill mentally, which is known as mental imaginary. This skill learning technique is important in sports and rehabilitation. It is now known that mental imaginary learning is due to perceptual processing. There are many visual learning aids available: such as photos, illustrations, icons, symbols, sketches, figures, and concept maps etc. Imagery of music activates the auditory and frontal cortices.
Right option is false.
4. Massed practice is practice that occurs without rest between trials. It is a is continuous practice where there are few or no pauses for rest even of short duration relative to the work interval. Thus, it involves longer hours of practice with less rest. On the other hand, distributive practice involves more rest intervals between trails. Mass practice is better for discrete task while for continuous task distributive practice is better. There is fatigue generated in massed practice. This will be a disadvantage in continuous tasks such as swimming, cycling etc.
Right option is false.
As per Chegg’s rule, only one question needs to be answered.
