Study Notes
Motor Learning - PHYL 4518
- Course code: PHYL 4518
- Instructor: Zoe Chan, PhD
- Email: [email protected]
- Semester: F2024
- Week: 13
Experts vs. Novices
- Experts switch attention more frequently than novices.
- Experienced surgical nurses:
- Switch attention less frequently.
- Know when and where to place attention for effectiveness.
- Demonstrate a "quiet eye," fixating on the target for 1-2 seconds before the action.
- Show more prediction and anticipation of future actions.
- 14/29 correct responses on the expert/novice attention question.
- 15 (51.7%) responses indicated true and 14 (48.3%) responses indicated false.
Today's Learning Objectives
- Understand schema learning and when to use variable and constant practice.
- Understand the differences between blocked and random practice and the research benefits of random practice.
- Understand overlearning.
- Explain the role of modeling and imagery in learning, including the basic neurophysiology.
- Understand the difference between mastery goals and performance goals.
Goal of Practice
- Goal of practice: Perform at the highest possible level when performance counts.
- Conditions are usually variable.
- How to prepare for variable parameters?
Common Example - CPR
- Practiced in a sterile, stress-free environment.
- Performance conditions in real-world scenarios are different.
Generalized Motor Program (GMP)
- A skill represents a class of movements (e.g., throwing a football).
- Contains various parameters (e.g., distance, height, arm angles, targets).
- Contains fundamental and consistent characteristics (invariant features).
- Includes relative timing of muscle activation (set position, step, follow-through).
- Discrete movement patterns are governed by GMPs.
- Each parameter can be adjusted depending on the case (e.g., a football pass in different weather conditions).
Schema Learning
- For each parameter of a GMP, a relationship is created based on each practice trial.
- Builds the GMP.
- Football throw distance example: Schema determines the required force based on the throw distance, not by remembering every individual throw.
Variable and Constant Practice: Schema Learning
- Variable practice enhances schema learning.
- Constant practice: Repeat the same variant of the skill.
- Variable practice: Vary a parameter each time.
- Example: Throwing a football—constant practice would be at a distance of 7m, while variable practice would involve a range of distances between 5 and 11m.
Variable and Constant Practice: Early Skill Acquisition
- Constant practice outperforms variable practice in early skill acquisition.
- However, variable practice performs as well or better in novel situations.
- Constant practice: 5, 7, 9 or 11 mph
- Variable practice: 5, 7, 9 and 11 mph.
- Data from Catalano & Kleiner, 1984 show absolute error values for constant and variable practice groups at different transfer test velocities.
Block vs. Random Practice
-
In most settings, the goal is to learn several skills simultaneously. (e.g., physicians practicing suturing and knot tying; soccer players practicing shooting, passing, heading, receiving passes)
-
Two approaches:
- Blocked practice: Practice all trials of one skill before switching to another (E.g., working on shooting, then passing, then heading).
- Random practice: Practice trials are interleaved (E.g., working on all 3 skills repeatedly).
Block vs. Random Practice: Shea and Morgan Experiment
- 3 tasks to be learned under blocked or random conditions.
- Retention tests were administered 10 minutes later and 10 days later.
- Results: Random practice produced better performance, especially when tested randomly.
- Acquisition and retention were tracked during the experiment. Data presented in a graph.
Block vs. Random Practice: Why?
- Elaboration hypothesis: Considering different skills in random practice creates meaningful connections and elaborations between the different trials, facilitating skill acquisition.
-
Forgetting hypothesis: Forgetting solutions between skills in random practice strengthens skill learning by forcing the learner to re-learn and recall solutions frequently, leading to stronger connections in memory.
- Blocked practice: You remember how to perform the movement trial to trial.
- Random practice: You forget the solution between tasks and produce solutions, facilitating further learning.
Block vs. Random Practice: Testing the Forgetting Hypothesis
- 3 groups: Blocked, Random, Random + model.
- Random + Model: Model shows skill performance, enhancing the blocked group, eliminating the random practice's benefits.
- Data displayed in a graph showing absolute constant error over time (immediate and delayed retention).
Block vs. Random Practice: Research Since Shea and Morgan
- Random practice is generally shown to be better than blocked practice in various contexts, including badminton serves, baseball pitches, handwriting, and learning musical pieces (e.g., clarifying songs).
- Evidence from various studies supports the benefits of random practice over blocked practice.
Reading
- Relevant reading link provided (https://sirc.ca/blog/motor-learning-to-enhance-athlete-skill-development/).
Overlearning
- Overlearning: Continual practice beyond the point of peak performance to enhance resistance to forgetting, with a focus on the repetition of the process, not just the movement.
- More resistant to forgetting.
- Enhances movement adaptability and flexibility.
- Expert blacksmiths hit the same point. They use different movement patterns each time.
Mental Practice: Modeling and Imaging
- Regular mental practice is a common behavior in high-level performers.
- Techniques include imagery/visualization, observational learning (modeling), relaxation and stress control, positive self-talk, and attention control.
Modeling (Observational Learning)
- Instructor or model demonstrates the skill in person or on video, and the learner mimics the skill.
- Learner absorbs coordination, sequencing, and timing information.
- Constraints (including goals) influence the task.
- Learners focus on end points or distal effector actions; this provides the most information regarding the overall movement.
- Similar to external focus of attention.
Modeling: Neuroscience
- Some visuomotor neurons (mirror neurons) are active during observation and execution.
- Motor resonance system: Understand the action, intention, enable imitation, and understand the behavioral state of the model.
- Less active when observing non-human actors, impossible movements, or unfamiliar tasks.
Imagery
- Imagery: Mental or cognitive rehearsal of a skill, used for skill acquisition and preparation.
- Skill acquisition: Learners model the skill in their own minds repeatedly.
- Techniques include skill rehearsal, arousal modification.
- Imagery without physical practice is marginally successful. Combining both physical and mental practice is more beneficial.
Imagery: Neuroscience
- Different brain areas are active in experts and inexperienced individuals during imagery.
- Experts activate motor areas. Inexperienced individuals activate visual areas.
- fMRI data illustrate the different brain activations in experts and novices.
Imagery: Controversial Benefits
- Weeks of mental imagery of weight-lifting improves strength.
- Results may include better central commands, increased motor unit activation, and more efficient inter and intramuscular coordination.
- Some studies indicate improved finger abduction and elbow flexion after weeks of strength training imagery.
- Data comparing imagery and control groups with regards to weightlifting/strength training exists.
Imagery in Stroke Rehabilitation
- Stroke-affected individuals: Partial paralysis, often on one side.
- Active movement may be dangerous without supervision.
- Mental practice is a beneficial addition.
Intention Toward Improvement and Mastery
- Practice must have goals to overcome weaknesses, maximize strengths, or change techniques based on individual learner characteristics.
- Mastery goals: Enhance skill and comparisons are made to oneself.
- Performance goals: Win or be better than someone else.
- SMART goals (Specific, Measurable, Achievable, Relevant, and Time-Bound).
Goal Setting
- Specific goals are superior to "do your best" goals for acquisition and retention.
- Experimenters set more realistic goals, thus avoiding motivation decline. Goal-setting data (graph) is presented for 'do your best', experimenter set and participant set goals.
Intention Toward Improvement and Mastery
- Successful coaches plan and organize practice with precisely defined goals and objectives (individual and team).
- Effective practices are short, intense, and organized.
Reminders
