Q

  • It develops slowly through __________ of an act over many trials.
  • It involves a network of specific ________, ____-_______, ________, and ______________ structures.
A
  • automatically
  • repetition
  • frontal, basal-ganglion, parietal, and cerebellar structures (striatum)
20
Q

Explicit (declarative) Learning:

  • Results in knowledge that can be ___________ recalled and thus requires processes such as awareness, attention, and reflection.
  • Involves the ability to remember factual knowledge.
  • Constant repetition can transform declarative into __________ or _________ knowledge.
  • What is an advantage of explicit (declarative) learning?
A
  • consciously
  • nondeclarative or procedural
  • It can be practiced in ways other than the one in which it was learned.
21
Q

What are the neural pathways involved in explicit (declarative) learning?

A

frontal brain areas such as anterior cingulate, prefrontal cortex, head of the caudate, medial temporal lobes, hippocampus.
-the hippocampus codes a cognitive map of the spatial areas in which we move - internal representation

22
Q

To optimize teaching movement skills – the patient should be highly ________, attend fully to the task, and be able to relate or _______ the new information to information they already know about the task.

A
  • motivated

- integrate

PART 2: THEORIES OF MOTOR LEARNING

A

PART 2: THEORIES OF MOTOR LEARNING

24
Q

Theories of Motor Learning is a group of abstract ideas about the nature and control of the acquisition or modification of movement. What are the (3) we will be discussing?

A
  • Adam’s Closed-Loop Theory
  • Schmidt’s Schema Theory
  • Ecological Theory
25
Q

Adams Closed-Loop Theory:

  • _______ ________ used for the ongoing production of skilled movement.
  • ________ _______ used in the _________ and __________ of the movement.
  • _________ ________ built up over a period of practice and becomes the internal reference of __________.
A
  • sensory feedback
  • memory trace, selection and initiation
  • perceptual trace, correctness
26
Q

With Adams Closed-Loop Theory it is essential to have the patient do what? Why?

A
  • Have the patient practice the same exact movement repeatedly to one accurate endpoint.
  • The more time spent practicing the movement as accurately as possible the better the learning will be.
27
Q

With Adams Closed-Loop Theory, errors produced during the learning ________ the strength of an incorrect perceptual trace.

A

increase

28
Q

What are the limitations of Adams Closed-Loop Theory? (3)

A
  • The theory cannot explain the accurate performance of novel movements or open‑loop movements made in the absence of sensory feedback
  • It may be impossible for the brain to store a separate perceptual trace for every movement ever performed (or is this muscle memory??)
  • Variability in movement practice may actually improve motor performance of the task – depending on the type of task.
29
Q

Schmidt’s Schema Theory:

  • Generalized motor program contains the rules for creating the spatial and temporal patterns of muscle activity needed to carry out a given movement.
  • ______ schema is used to select a specific response.
  • _________ schema is used to evaluate the response.
  • Think of a toddler learning the rules for what a dog is.
A
  • Recall

- Recognition

30
Q

With Schmidt’s Schema Theory, optimal learning will occur if a task is practiced under _________ circumstances.

A

different

31
Q

What are the limitations of Schmidt’s Schema Theory? (3)

A
  • Differences between children and adults with variable forms of practice.
  • Lack of specificity of interaction with other systems during motor learning.
  • Inability to account for the immediate acquisition of new types of coordination.
32
Q

Ecological Theory:

  • Motor learning is a process that increases the coordination between perception and action consistent with the _____ and ___________ constraints.
  • The theory emphasizes dynamic exploratory activity of the perceptual/motor workspace to create optimal strategies for performing a task.
A

task and environmental

33
Q

With Ecological Theory, the patient learns to distinguish the relevant _________ cues important to organizing action.

A

perceptual

34
Q

What are the limitations of Ecological Theory? (2)

A
  • Still a very new theory.

- Has not been applied to specific examples of motor skill acquisition in any systemic way.

35
Q

“How” motor learning occurs may depend on the ________ _____, the stage of ________, and the _________ in which the movement occurs.

A

37
Q

Describe the cognitive stage of motor learning.

A

The learner attempts to understand how to perform a skill.

38
Q

Describe the intermediate or associative stage of motor learning.

A

The learner begins to modify and/or adapt the movement pattern as needed.

39
Q

Describe the autonomous stage of motor learning.

A

Movement execution becomes more automatic and attention can be directed elsewhere.

40
Q

In the intermediate or associative stage of motor learning, what is counterproductive when they enter this stage?

A

-facilitation techniques and/or manual guidance

41
Q

What can you start to introduce in the autonomous stage of motor learning?

A

distractions during therapy such as conversations (dual-task)

42
Q

What are Neo-Bernsteinian Perspective 3 stages of motor learning? Describe them.

A

Novice: learner simplifies the movement problem by “freezing out” some of the available degrees of freedom.
Advanced: learner begins to reinstate and/or release additional degrees of freedom.
Expert: additional degrees of freedom released, additional passive forces exploited.

43
Q

How can we asses motor learning?

A

Performance Curves

44
Q

A

Overlearning (postmastery)

45
Q
  • _____ _____ paradigm is used to determine the degree of automaticity of performance.
  • What is acceptable degree?
A
  • dual task
