Unit one Flashcards
Motor control is ?
Performing a skilled movement
Motor learning is?
Acquiring a skill
What are the 4 things does a skilled movement require?
It must be: purposeful, appropriate, effective, and efficient.
Physiology and perceptual motor behaviour is part of what?
The fundamental science
What are the 2 categories of applications?
Assessing performance and improving performance.
How well a task is completed is known as what?
Performance.
List the three required considerations of performance.
- task- required task
- the person
- the context (what else is going on)
A spatial goal is the goal of a task in space vs. time, what does it mean if your task has a spatial goal?
That you need to get something to a location in space.
Ex: hockey
A temporal goal is the goal of a task in space vs. time, what does it mean if your task has a temporal goal?
That you need to do something quickly.
What is a hybrid goal, also part of space vs. time?
Involves both spatial and temporal goals. so you need to get to a location and do it quickly.
Ex:surgeon
When the movement is the important part of the task what kind of focus is it?
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.
When the outcome of the movement is the important part of the task what kind of focus is it?
Outcome focus, example hockey, the movement doesn’t necessarily matter but the outcome of that movement does.
Integration of task parts involves both serial and continuous, what is the difference between these two?
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.
When success is determined via non-motor factors what kind of task is it?
Cognitive, example chess.
When success is determined via motor factors what kind of task is it?
Motor.
Explain the difference between an open and closed task.
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.
What are the three levels of measuring performance?
- outcome level- spatial or temporal
- movement level-kinematics
- cause level-kinetics or physiology
A task with spatial goals ….
Has clear targets.
Constant Error - list everything you know.
- is consistent misses
- average all of the movements
- location is important
- involves accuracy
- includes the average endpoint.
Variable Error- list everything you know.
- inconsistency
- how far each movement is from the average
- precise
- scatter, would have a lot if it is variable error.
How many measurements will need to be given when describing performance?
4- both CE and VE in both the X and Y direction.
What makes radial error different from both CE and VE?
it blends the X and Y components.
If you are doing an aiming movement and are missing consistently what kind of measure should you use?
CE
If you are a inconsistent with learning and want to measure scatter, what kind of measure should you use?
VE
Reaction time includes what ?
Both premotor and motor reaction time, both of these include the time the brain is waiting and preparing for movement.
Premotor reaction time is from the start signal to what ?
muscle activity, which an EMG will detect, this is the processing stage for movement prep.
Motor reaction time is from what and ends when ?
From the onset of the EMG detecting prep until the movement happens, it will end when the movement changes.
What is movement time?
The time it takes to complete the movement needed from the time you begin movement.
What two things determine movement time?
physical features and psychomotor aspects
What makes response time?
both reaction and movement time added together.
The study of movement, that involves measuring position and displacement, velocity, and acceleration is what?
Kinematics
How many ways can a linear kinematic task be measured?
Time, reaction time, spatial movement, constant and variable error.
The 2 categories of measures are?
mechanical and physiological.
How is metabolism relevant to MC/L?
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.
