Study Notes
Memory Systems
- Long-term memory (LTM) includes episodic memory (events), semantic memory (facts), nondeclarative memory (implicit), procedural memory, and conditioned responses.
- Explicit memory: memories a person is aware of and can verbalize.
- Implicit memory: memories formed without awareness; they may be unverbalizable.
- Patient H.M.'s case demonstrated that implicit memories could be formed even with brain damage and selective impairments to declarative memory (e.g., learning new motor skills).
Skill Learning
- Skill learning involves serial reaction time tasks, random events, and repetitive patterns.
- Reaction times improve with practice in repetitive patterns.
- Procedural memory guides "knowing how" which involves improvements from practice and doesn't require conscious awareness.
- Skill learning often combines perceptual-motor and cognitive components.
- Skill learning is not always purely open or closed, or perceptual-motor or cognitive.
Skill Acquisition Stages
- Stage 1 (cognitive): learning declarative knowledge about the skill.
- Stage 2 (associative): using learned knowledge and improving procedural skills, including chunking actions and error correction.
- Stage 3 (autonomous): high automaticity, minimizing reliance on conscious thought, transitioning to implicit memory.
Optimizing Practice
- Transfer Specificity: skills may not readily generalize to dissimilar environments.
- Contextual Interference: alternating between different tasks (high CI) during practice can lead to better long-term retention and improved performance than repetition of the same task (low CI).
- Desirable Difficulties: short-term learning can be enhanced by difficult practice situations that might slow initial learning but improve long-term retention and transfer.
- Variable Practice: using diverse practice conditions to support generalization and flexible responses.
Feedback
- Knowledge of Results (KR): feedback on performance allows for evaluation of the effectiveness of actions and provides an opportunity for error correction.
- External Feedback: different from internal monitoring, which can include body position awareness and confidence.
Continuous vs. Intermittent Feedback
- Continuous feedback is beneficial for initial learning (performance improvement during learning) but may lead to less permanent acquisition.
- Intermittent feedback may be less helpful initially, but can result in more robust procedural memory over the long term.
Muscle Memory
- "Muscle memory" is inaccurate; procedural memory is stored in the brain.
