Identifying Causes of Errors

  • Categories of Errors in Performance:

    • Errors can be classified as follows:

    • Errors due to constraints, including:

      • Developmental level.

      • Equipment used.

      • Structural issues with the task or drill (e.g., throwing).

      • Environmental changes.

      • Psychological factors such as fear.

    • Comprehension Errors:

      • Occur when the learner lacks understanding of skill requirements or expectations.

    • Response Selection Errors:

      • Can involve perceptual errors, decision-making errors, and recall errors.

    • Execution Errors:

      • Include neuromuscular coordination errors and issues related to the speed-accuracy tradeoff.

    • Sensory Errors:

      • Pertains to visual errors and proprioceptive errors.

Speed-Accuracy Tradeoff

  • Understanding the Speed-Accuracy Tradeoff:

    • Spatial Accuracy:

    • Increased emphasis on speed negatively affects spatial accuracy, and vice versa.

    • Temporal Accuracy:

    • Tends to improve if a performer increases movement speed or decreases movement distance.

    • Implications for Skill Acquisition:

    • Early stages should focus less on accuracy and more on overall practice.

Categories of Corrections

  • Types of Corrections Based on Difficulty:

    • RETRY:

    • A simple modification of an established pattern.

    • Easy to implement and requires little learning.

    • Changes can be made quickly and have a minimal adverse effect on performance.

    • REFINE:

    • Improvement of an established pattern.

    • Requires moderate effort and a reasonable amount of learning.

    • May involve initial performance decrement before improvement.

    • REBUILD:

    • Establishing a new pattern.

    • Difficult to correct and requires extensive learning.

    • May significantly impact performance negatively at first and can lead to negative transfer and frustration.

Feedback in Skill Development

  • Key Principles of Feedback Provision:

    • Effective instructors and therapists highlight the importance of providing feedback tailored to prepare individuals for independent performance.

    • Questions surrounding feedback include:

    • Should feedback be administered?

    • When is the right time for feedback?

    • What is the appropriate volume of feedback?

Types of Feedback

  • Categories of Performance Feedback:

    • Task Intrinsic Feedback:

    • Encompasses sensory-perceptual information such as vision, proprioception, and auditory sensations.

    • Naturally occurs during skill performance.

    • Extrinsic Feedback:

    • Supplementary feedback not inherent to the skill itself.

    • Enhances the intrinsic feedback obtained from sensory-perceptual experiences.

Importance of Extrinsic Feedback

  • Benefits of Extrinsic Feedback:

    • Enhances task-intrinsic feedback that learners can detect.

    • Provides information that may be missed by learner's sensory systems.

    • The amount of teacher feedback given correlates significantly to the appropriate practice levels students engage in.

Categories of Extrinsic Feedback

  • Two Distinct Types:

    • Knowledge of Results:

    • External information regarding the outcome of skill performance or goal achievement.

    • Knowledge of Performance:

    • Feedback pertaining to movement characteristics that led to performance outcomes.

Motivational and Reinforcing Properties of Feedback

  • Roles and Benefits of Feedback:

    • Motivational Properties:

    • Energizes learners to increase effort.

    • Reinforcing Properties:

    • Positive reinforcement, negative reinforcement, and punishment are all techniques to enhance learning.

    • Informational Properties:

    • Offers essential insight into performance improvement.

    • Dependency-Producing Properties:

    • Excessive reliance on feedback can hinder autonomous skill execution.

Strategies for Feedback Frequency

  • Methods to Adjust Feedback Frequency:

    • Faded Feedback:

    • Gradually reducing the frequency of feedback over time.

    • Bandwidth Feedback:

    • Providing feedback only when performance is outside a designated range.

    • Summary Feedback:

    • Offering feedback summarizing multiple attempts rather than immediate assessment.

    • Average Feedback:

    • Delivering average performance feedback over several attempts.

    • Self-Control Feedback:

    • Allowing learners to control the timing and frequency of feedback they receive.

Knowledge of Performance Feedback

  • Distinct Types of Knowledge in Performance:

    • Verbal Knowledge of Performance:

    • Crucial for providing comprehensive skill analysis to improve performance.

    • Video Replay:

    • A powerful tool that captures performance attempts for repeated viewing.

    • Learners need to understand what to focus on and how to interpret the footage.

    • Video Feedback Learning Stages:

    • Shock

    • Error Detection

    • Error Correction

    • Independence

Verbal Knowledge of Performance Feedback

  • Usefulness and Types of Verbal Feedback:

    • The content of verbal performance feedback is critical for skill improvement.

    • Practitioners must prioritize the most critical components of the skill during feedback.

    • Types of Verbal KP Statements:

    • Descriptive KP:

      • Simply describes the movement without suggestions for change.

    • Prescriptive KP:

      • Indicates what the learner must do to correct mistakes.

    • Best practices suggest using prescriptive feedback in the early stages and descriptive feedback as skills develop.

The "Sandwich" Approach to Feedback

  • Structure of Providing Feedback:

    • Feedback should be structured so that corrective information is sandwiched between reinforcement and motivational support:

    • Information to reinforce correct performance.

    • Information to assist in error correction.

    • Encouragement to motivate the learner to implement recommendations.

Precision of Augmented Feedback

  • Adjustments During Different Learning Stages:

    • In early learning stages, feedback can be general yet effective for guiding improvement.

    • As skills become refined, more precise feedback becomes beneficial, provided that the learner possesses the requisite understanding.

Guidance Hypothesis and Frequency of Feedback

  • Implications of Feedback Frequency on Skill Acquisition:

    • Feedback aids in error correction but excessive feedback can hamper skill acquisition.

    • It is suggested that children may benefit from more consistent feedback to build confidence and understanding.

Feedback-Delay Interval

  • Timing of Feedback Delivery:

    • Providing feedback too soon may inhibit learners from self-evaluating their movements, disrupting the development of error detection and correction strategies.

    • Practitioners can facilitate learning by prompting reflective thinking through targeted questions.

Post-Feedback Interval

  • Synthesis of Feedback Information:

    • Learners utilize the post-feedback interval to process received information, both internal and external, and formulate adjustments.

    • Practitioners should encourage active processing of feedback for movement modification and check for understanding.

Modes of Instruction

  • Prescriptive vs. Guided-Discovery Approaches:

    • Variability of practice involves diverse methods:

    • Demonstration.

    • Verbal instruction.

    • Contextual interference.

    • Feedback precision, frequency, and timing influence learning outcomes significantly.

Challenging Traditional Myths in Instruction

  • Common Misconceptions in Skill Learning:

    • Myth 1: Demonstrations are not universally effective for all learners.

    • Myth 2: Specific, blocked practice is not always essential for learning a skill.

    • Myth 3: Frequently providing detailed augmented feedback may not improve performance outcomes.

    • Myth 4: Prescriptive coaching is not always superior to guided discovery approaches.

    • Myth 5: Game intelligence skills can be instructed and practiced effectively.
