Study Notes
Skill Acquisition Stages
- Cognitive Stage: Characterized by understanding the task conceptually and relying heavily on declarative knowledge (knowing what to do).
- Associative Stage: Refining the skill through practice, reducing errors, and improving accuracy.
- Autonomous Stage: Skill becomes automatic, requiring minimal conscious thought.
Power Law of Learning
- Performance increases rapidly with initial practice, then slows down as expertise develops.
- Demonstrates a diminishing returns effect.
- Represented by the formula: T = aP^-b (where T is task time, a is initial time, P is practice, and b is the rate of learning).
Asymptotic Learning and Retention
- Performance approaches a limit (asymptote) as practice increases.
- Skills can decay over time without practice ("use it or lose it").
- Some skills, like driving, retain high levels of retention with minimal decay.
ACT Theory
- Divides knowledge into declarative (facts) and procedural (knowing how).
- Skills develop as declarative knowledge becomes procedural through practice.
- Proceduralisation: The transition of declarative knowledge to automated processes.
- Practice strengthens procedural knowledge, making it faster and more reliable.
Instance Theory
- Learning involves storing instances (past solutions).
- Retrieval becomes faster as more instances are stored.
- Task performance transitions from algorithmic processing to instance retrieval (relying on past experiences).
Expert Memory and Chunking
- Experts don't necessarily have better overall memories; their expertise is domain-specific.
- Chunking: Organizing information into meaningful units to improve memory and recall
- Example: Expert chess players chunk pieces based on their functions, enabling better recall than novices.
Expertise and Processing
- Experts process information differently, focusing on deep underlying principles rather than surface features.
- Example: Expert physicists think in terms of principles, while novices focus on individual equations.
Implicit Learning
- Some skills develop implicitly, meaning individuals learn to perform tasks without conscious awareness of the rules.
- Often occurs through repeated exposure or practice.
Expert-Novice Differences
- Novices operate on surface-level information.
- Experts develop broader, interconnected units of knowledge.
- Experts are faster and more accurate due to chunked, principle-based strategies.
Challenges of Expertise
- Expertise can lead to bias or hinder performance in novel situations, as experts rely heavily on familiar patterns.
Kolers (1976) Experiment
- Demonstrated the Power Law of Learning using reading inverted text.
- Participants' reading speed increased dramatically with practice but decayed after a year.
de Groot, Chase, and Simon (1973) Experiment
- Chess experiments showed how chunking helps experts remember configurations by processing meaningful patterns rather than surface details.
