Motor Learning Chapter 4

Question 1

What are the sources of sensory info?

Answer 1

Exteroception

Proprioception

Question 2

• information from the environment

- outside the body

Answer 2

Exteroception

Question 3

• -info from bodily movements

- -primarily muscles & joints

Answer 3

Proprioception

Question 4

The 4 proprioceptive receptors are

Answer 4

Vestibular apparatus
muscle spindles
Golgi tendon organs
Cutaneous receptors

Question 5

This proprioceptive receptor is key for balance

Answer 5

Vestibular Apparatus

Question 6

This proprioceptive receptor give us information on the stretch & force production

Answer 6

Golgi tendon organs

Question 7

This proprioceptive receptor is most delicate, gives info on temp, pressure, sensitivity. Located just below epidermis

Answer 7

Cutaneous receptors

Question 8

Closed loop control is broken down into the following tasks:

Answer 8

• Comparator
• Executive
• Effector
• Feedback

Question 9

The comparator is in charge of

Answer 9

error detection

Question 10

the executive is in charge of

Answer 10

determining the actions to take in order to reach a goal

Question 11

the effector is in charge of

Answer 11

carrying out the decisions

Question 12

the feedback is in charge of

Answer 12

providing information on current state

Question 13

In the summary the closed loop control:

Answer 13

• primarily used to control slow/deliberate movements
• allows us to make compensations
• used primarily in continuous task

Question 14

Some limitations of closed loop control are that:

Answer 14

• it makes control very slow

- this type of control is not adequate for discrete/rapid skills

Question 15

This type of response is 
-most rapid reflex (30-50 ms) 
-unconscious 
-little environmental impact 
-inflexible
(---good example of response is sway )

Answer 15

M1 response

Question 16

This type of response is:

• 51 to 81 ms
• more flexibility than m1
• largely unconscious, but sensitive to instructions

Answer 16

M2 Response

Question 17

The three types of visual systems are

Answer 17

• dorsal stream
• primary visual cortex
• ventral stream

Question 18

This type of vision is

• identify objects in the center of the visual field
• under conscious control
• affected by light
• involved in movement planning

Answer 18

ventral stream processing

Question 19

This type of vision is characterized by

• specialized for online movement control
• involves the entire visual field
• not under conscious control
• optical flow

Answer 19

dorsal stream movement control

Question 20

This type of vision is:

• def: time to contact
• object position and direction
• motion
• stability and balance .
• Velocity

Answer 20

optical flow

Question 21

each visible feature collects visible light, which enters the eye at specific angles; collectively this is called

Answer 21

Optical array
