Define Fitts' Law.

Fitt's Law states that when amplitude and width are constant, movement time will also remain constant. **BE MORE DESCRIPTIVE**

Briefly list and explain how the 3 phases of information processing relate to the sport skill of your choice.

A goalie sees a ball coming in their direction. This input or stimulus is then recognized in the stimulus identification stage where the visual senses will be sent to the brain for processing. The goalie will either duck to avoid being hit by the ball or catch the ball to prevent the opposing team from getting a goal. Once the response is decided it is then sent as an output by the efferent neurons. This will initiate a motor response or output.

Describe a situation when relatively long rest periods should be employed (distributed practice).

Any situation involving a continuous task should use the distributed practice schedule. It is proven that with these types of tasks, longer rest periods lead to a positive practice and positive learning effects. An example of this would be running. When I run, I feel that longer rest periods between the activity result in better performance on my next lap. The longer I have to catch my breath, hydrate and stretch out, the better and much easier the next laps are for me.

When is it best to use blocked practice and when is it best to use random practice?

Blocked practice would be best in the case of free-throws or track and field exercises. Since there is no variation in this type of shot, there is only one way to practice it. The situation never changes and the environment never changes. Random practice would be best used in drills such as different types of passes made in basket ball or different ways to serve in tennis.

As the number of possible alternatives increases, reaction time increases. This is known as:

Hicks law

List two similarities and three differences between 'knowledge of performance' and 'knowledge of results.'

Knowledge of performance and knowledge of results are both types of augmented feedback. They also both produce motivation. Knowledge of performance is very qualitative and will give learners feedback on their patterns of action, where as knowledge of results gives feedback related to the goal. Knowledge of results directs the learners attention to an externally directed focus. Where as the knowledge of performance directs the learners attention to internally directed focused. Knowledge of results is often used in research, where knowledge of performance is more common in daily activities.

_______________ is extrinsic information provided after the action is completed that tells the learner about the degree to which the goal was achieved.

Knowledge of results

Playing a song on a piano is best classified as a:

Serial motor skill

Name and discuss the two hypotheses offered to explain the blocked versus random practice effect.

The elaboration hypothesis and the Forgetting Hypothesis are the two hypotheses that explain the blocked vs random practice effect. The elaboration hypothesis found that by changing the different tasks in different random-practice trials resulted in the participants showing an increase in learning. This is because this changing of tasks made each task more distinct from one another and created more elaborate memory representations of each task. This increased performance, learning and retention.

The elaboration hypothesis and the forgetting hypothesis are complementary rather than competing explanations for the blocked-random practice effect.

What is a transfer design and what are the main features of it?

A transfer design helps to determine if a change that improves performance actually improves learning as well. The main features of this design are that it allows enough time for the temporary effects to go away to determine what has actually been learned and that the participants will be tested again in a given time frame under common conditions.

________ error measures the distance from a target without considering direction.

Absolute

In one complete sentence, explain why accuracy improves when you generate maximal force during a task as opposed to moderate force generation.

Accuracy improves when generating maximal force because the forces become consistent. Because of this, by increasing the speed and load, it becomes more accurate and decreases error.

Give 1 example of 'far transfer,' that is not in your textbook.

An example of a far transfer would be throwing a football and kicking a soccer ball.

Which is the term that best describes a skill with arbitrary beginning and end locations?

Continuous motor skill

Flipping on a light switch is best classified as a:

Discrete motor skill

List different types of stimuli you can receive from the environment to be used during the Stimulus Identification Stage.

During the stimulus identification stage, the most common types of stimuli to be picked up from the environment are auditory and visual stimuli. Touch and pressure are considered proprioception because they are detected by the cutaneous receptors inside the skin. Therefore, this information comes from inside the body and not the environment. Another type of stimuli could be scent, for example, you smell a fire so you know to exit the building.

If practice is given for one variant of a movement, then the learner should be able to transfer that learning to any other variant using a different pattern.

False

Transfer decreases between two tasks as similarity between them increases.

False

Attention narrowing or perceptual narrowing can be effective or ineffective. Explain and cite an example for each

Perceptual narrowing can be effective when you are in a room full of distractions but you maintain your focus on your work. However, if you were to have this same narrowing of perception while doing something such as driving, you could become a danger to yourself or others because you are unintentionally avoiding the things going on around you.

Which is NOT a characteristic that is common to motor skills?

Performed involuntarily

Which of the following would more than likely demonstrate skill based on its definition?

Riding a bicycle around the block

Briefly describe characteristics of short term memory.

Short term memory can last for only a few minutes. Short term memory store only lasts for about a few seconds. This is only long enough to remember what someone said for you to create a response. Short term memory however is a little longer for things that may not be permanent but are needed to be remembered longer than a few seconds.

When we define learning, what are the key features to consider?

Some key features to consider when defining learning is the improvement in a skill, the time it takes to learn these skills and get better, performance and practice. I feel that it is also important to take the individual's experience into consideration as well as the skill at hand. It is important to consider that learning comes from practice and experience and that it cannot be measured and it is not observable. It is also important to understand that if someone truly learned something, it is relatively permanent.

What is the Inverted-U Principle? Explain how it can affect students and/or athletes. If you are a coach or a teacher, how could you use the Inverted-U Principle to your benefit?

The Inverted-U principle helps to describe the relationship between arousal and performance. This principle identifies that there is an optimal zone where a specific level of arousal will promote better performance. To students and athletes this could be beneficial. It is easy to get overwhelmed in school and sports but once they know that too much stress can harm their performance, they are more likely to try to find ways to cope and bring their arousal down to optimal levels. As a coach or a teacher you could use this to your benefit by encouraging the students to find their optimal levels because when they excel, so do you. I remember my psychology teacher explaining that too much arousal is a bad thing and that if we were ever feeling overly anxious to listen to classical music and that not enough arousal was also bad and to listen to up beat music to pump us up before exams.

In specific terms, describe how the Psychological Refractory Period operates. Cite an example to help illustrate your answer.

The Psychological Refractory Period works by increasing the reaction time to promote a delayed response. This works because the person who is being "faked" is anticipating a different action and is prepared to act accordingly. By the time they realize it was a fake, they are already responding to it. It takes more time to recognize this false response and then to recognize the actual response. This is because of the Bottle neck. While more than one stimulus can be processed at once, only one motor output can occur at a time.

Briefly describe how the closed-loop system of control works. Cite an example to help illustrate.

The closed-loop system works through a series of trial and error or feedback with necessary corrections. Once your input is processed and a response is selected in the executive stage, it is then passed along to the motor programming, through the spinal cord and then through the muscles, which is all known as the effector stage. Once the movement is performed, feedback is then given both internally through proprioceptive feedback, and externally with exteroceptive feedback. In the comparator, the actual feedback is then compared with the anticipated feedback. If the anticipated feedback does not match, motor programming will adjust accordingly to meet this desired feedback. An example of this would be accelerating in a vehicle. My car typically juts forward, I am aware of this so I know not to push on the gas too hard. When I get in other people's vehicles, I don't push as hard at first and don't accelerate as desired. When I try the next time, I will know to push harder on their gas pedal because it will not jut forward as mine does. The same happens when someone drives my car and they aren't prepared for quick acceleration. I can tell that they are alarmed because it is not what they expected to happen and they know to correct it the next time they accelerate.

Motor control is best described as:

The neural, physical, and behavioral aspects of movement.

What is the Specificity Hypothesis?

The specificity hypothesis predicted that if a person was good at a given skill, they would have a strong general motor ability. If this was true, they would be predicted to score well on the next skill tested.********THE OPPOSITE. HENRY'S SPECIFICITY HYPOTHESIS STATED THAT MOTOR SKILLS DON'T TRANSFER. THAT JUST BECAUSE YOU'RE GOOD AT ONE THING DOESN'T MEAN YOU'LL EXCEL AT ANOTHER.

List 3 factors that affect reaction time AND describe the effect of each.

The stimulus plays a major role in reaction time. If you do not recognize the stimulus it will take you longer to react. The number of alternatives that you have to choose from will also determine the reaction time. The less options that you have the quicker the reaction. Whether the stimulus is stimulus-response compatible or not plays a role. If something doesn't make sense to your brain, it will take a longer time to process it.

What term has been coined the explain individuals with higher levels of general motor ability? What does this term mean? Do you believe it's a real thing? Why or why not?

The term is called superability. This term means that these individuals have many motor abilities and would be predicted to exceed in different skill sets. I believe that it is a real thing because there are many people out there that exceed at many things. Abilities can't necessarily be taught so I believe if they have a very wide skill set and have many of the abilities listed, then it does exist.

Describe the 2 exceptions to Fitts' Law and list an example for each.

The two exceptions are very forceful movements and movement timing. Maximal effort can be more accurate than trying to find the perfect medium of force and speed. An example would be kicking a ball at maximal effort. It is more likely to go right where you need it to if you don't overthink it and kick it as hard as you can in that direction. When trying to find a medium between the force you should kick it with or the speed, you can create more errors. Movement time is also an exception to the law because there are two different types of accuracy. With temporal accuracy, you are looking at when you should hit the target, such as a batter in baseball. When looking at spatial accuracy it is where you should hit the target in space. An example of this could be shooting a target. Both of these are important because as movement time decreases the variability of timing also decreases.

While walking and reading a book, you are able to weave through a row of chairs spaced three feet apart. List the name of the 2 visual systems that allow you to do this and briefly explain the role of each.

The ventral and dorsal visual systems allow this to be possible. The dorsal visual system is also called the ambient system. This system includes both the central and peripheral vision but allows you to tell what is around you and what to avoid. The dorsal visual system operates nonconsciously. It identifies where we are in reference to the environment around us. The ventral visual system is also called the focal system. It is strictly the central vision and helps us to focus on objects in front of us. This system is a conscious system so every time it is used, it is used consciously. It helps us to identify what is in front of us. ***Also apply to the example given

Specificity of learning suggests that what you learn depends on what you practice.

True

Stimulus identification is primarily a sensory stage.

True

Transfer between two well-learned tasks is low.

True

Transfer can used as an effective teaching strategy.

True

Explain the following statements: 1) Performance and learning are different, and 2) performance can interfere with learning.

Your Answer: 1. Performance and learning are different because performance is often viewed as an outcome of learning. 2. Performance can interfere with learning because someone may fail to grow in their learning or miss out on learning experiences if they are focused on performance. Also, someone may miss a chance to develop over time because someone else's performance at that given time was better than theirs.
