Unit one

Question 1

Motor control is ?

Answer 1

Performing a skilled movement

Question 2

Motor learning is?

Answer 2

Acquiring a skill

Question 3

What are the 4 things does a skilled movement require?

Answer 3

It must be: purposeful, appropriate, effective, and efficient.

Question 4

Physiology and perceptual motor behaviour is part of what?

Answer 4

The fundamental science

Question 5

What are the 2 categories of applications?

Answer 5

Assessing performance and improving performance.

Question 6

How well a task is completed is known as what?

Answer 6

Performance.

Question 7

List the three required considerations of performance.

Answer 7

1. task- required task
2. the person
3. the context (what else is going on)

Question 8

A spatial goal is the goal of a task in space vs. time, what does it mean if your task has a spatial goal?

Answer 8

That you need to get something to a location in space.

Ex: hockey

Question 9

A temporal goal is the goal of a task in space vs. time, what does it mean if your task has a temporal goal?

Answer 9

That you need to do something quickly.

Question 10

What is a hybrid goal, also part of space vs. time?

Answer 10

Involves both spatial and temporal goals. so you need to get to a location and do it quickly.
Ex:surgeon

Question 11

When the movement is the important part of the task what kind of focus is it?

Answer 11

Process focus, example figure skating, the patterns of movement matter. Think if the movement matters than the process at which that movement occurs …. ie: process focus.

Question 12

When the outcome of the movement is the important part of the task what kind of focus is it?

Answer 12

Outcome focus, example hockey, the movement doesn’t necessarily matter but the outcome of that movement does.

Question 13

Integration of task parts involves both serial and continuous, what is the difference between these two?

Answer 13

Serial is when there is a sequence of discrete movements and the order does matter.
Continuous is when you are repeating a signle movement and the order does not matter.

Question 14

When success is determined via non-motor factors what kind of task is it?

Answer 14

Cognitive, example chess.

Question 15

When success is determined via motor factors what kind of task is it?

Answer 15

Motor.

Question 16

Explain the difference between an open and closed task.

Answer 16

This is the variability of task, the difference is open tasks will have change from moment to moment while in closed tasks the goal is to reproduce same movememnt.

Question 17

What are the three levels of measuring performance?

Answer 17

1. outcome level- spatial or temporal
2. movement level-kinematics
3. cause level-kinetics or physiology

Question 18

A task with spatial goals ….

Answer 18

Has clear targets.

Question 19

Constant Error - list everything you know.

Answer 19

• is consistent misses
• average all of the movements
• location is important
• involves accuracy
• includes the average endpoint.

Question 20

Variable Error- list everything you know.

Answer 20

• inconsistency
• how far each movement is from the average
• precise
• scatter, would have a lot if it is variable error.

Question 21

How many measurements will need to be given when describing performance?

Answer 21

4- both CE and VE in both the X and Y direction.

Question 22

What makes radial error different from both CE and VE?

Answer 22

it blends the X and Y components.

Question 23

If you are doing an aiming movement and are missing consistently what kind of measure should you use?

Answer 23

CE

Question 24

If you are a inconsistent with learning and want to measure scatter, what kind of measure should you use?

Answer 24

VE

Question 25

Reaction time includes what ?

Answer 25

Both premotor and motor reaction time, both of these include the time the brain is waiting and preparing for movement.

Question 26

Premotor reaction time is from the start signal to what ?

Answer 26

muscle activity, which an EMG will detect, this is the processing stage for movement prep.

Question 27

Motor reaction time is from what and ends when ?

Answer 27

From the onset of the EMG detecting prep until the movement happens, it will end when the movement changes.

Question 28

What is movement time?

Answer 28

The time it takes to complete the movement needed from the time you begin movement.

Question 29

What two things determine movement time?

Answer 29

physical features and psychomotor aspects

Question 30

What makes response time?

Answer 30

both reaction and movement time added together.

Question 31

The study of movement, that involves measuring position and displacement, velocity, and acceleration is what?

Answer 31

Kinematics

Question 32

How many ways can a linear kinematic task be measured?

Answer 32

Time, reaction time, spatial movement, constant and variable error.

Question 33

The 2 categories of measures are?

Answer 33

mechanical and physiological.

Question 34

How is metabolism relevant to MC/L?

Answer 34

Because of the relation between movement- muscles move by having a signal from a neuron, that neuron gets its energy from the body which involves metabolism.
