Study Notes

Retention and Memory

Retention: People remember more information over time if it is personally relevant or connected to their daily experiences.
Ebbinghaus' Forgetting Curve: Memory decays rapidly at first, with a sharp drop in memory within hours or days after learning.
Real-world memories: People remember meaningful information longer and more steadily, contradicting Ebbinghaus' curve based on meaningless data.

Theories of Forgetting

Decay Theory: Memories fade over time if not accessed or rehearsed.
- Supported by Ebbinghaus' forgetting curve showing memory strength decreasing over time.
- Criticisms: Lacks explanation for memory retrieval and doesn't account for the retention of meaningful information.
Interference Theory: Other memories disrupt recall.
- Proactive Interference: Old memories interfere with new memories.
- Retroactive Interference: New memories interfere with old memories.
- Criticisms: Not always consistent, and the complexity of memory interactions makes it difficult to assess the extent of interference.
Retrieval Failure Theory: Memories are stored, but difficult to access without cues. Emphasizes the importance of cues and contexts for retrieval.
- Criticisms: Over-reliance on cues, and doesn't explain why some memories are poorly encoded in the first place.

Working Memory

Working Memory: A revised model of short-term memory, highlighting its role in processing and manipulating information.
Span: Working memory has a limited capacity, but its size can be affected by various factors.
- Attention: Larger working memory spans lead to better focus and ignoring distractions.
- Understanding: Facilitates comprehension of complex information.
- Problem-Solving: Supports thinking through steps and solving puzzles.
- Multitasking: Allows easier juggling of multiple tasks.
Evidence:
- Neuropsychological studies show patients with small working memory spans but normal long-term memory, suggesting different mechanisms for short-term and long-term memory.
- Transfer failure challenge: Not all information stored in short-term memory necessarily transfers to long-term memory.
- Dual-task performance: People can perform tasks simultaneously if the information is stored in different modalities or if the central executive's capacity is not exceeded.

Influence of Attention on Memory

Encoding (Learning): Dividing attention negatively affects encoding, leading to less effective learning and storage.
Retrieval: Dividing attention has a less severe negative effect, but still makes recalling information harder.

Real-world Forgetting

Forgetting Happens More Slowly: Real-world scenarios show a gradual decline in memory compared to Ebbinghaus' rapid drop.
Meaningful Information: Real-world memories tend to be retained longer, particularly those with meaning or frequent use.

Consolidation and Memory

Perseveration: The process of consolidating information into memory. If interrupted, the memory trace will not be consolidated, impairing recall. Longer perseveration leads to stronger memory traces.

Sleep and Memory

Sleep Enhances Memory: Sleeping immediately after learning improves memory.
Prevention of Dreaming: Blocking dreaming further enhances memory consolidation.

Circadian Rhythms and Memory

Circadian Influence: Rhythms influence alertness and memory performance throughout the day.
Morning vs. Evening: People have different optimal times for learning and remembering.
Afternoon Sleep: Memory is less effective if sleep occurs in the afternoon.

Interference and Forgetting

Proactive Interference: Prior learning interferes with new learning.
Retroactive Interference: New learning interferes with previously learned material.
McGeoch's Mechanisms: McGeoch suggests that forgetting is due to recalling unwanted memories (interference), not actual loss of information.
- Response Competition: Multiple potential responses compete for recall.
- Altered Context: Contextual cues influence memory retrieval.
- Set: A specific type of contextual effect.

State-Dependent and Encoding Specific Memory

State-Dependent Memory: Memory is better when retrieval occurs in a similar state to encoding (internal context).
Encoding Specificity: Similar to state-dependency, matching contexts between encoding and retrieval is key (external context).

Types of Memory

Episodic Memory: Memory for personal experiences and events bound to specific times and places.
Semantic Memory: Memory for general knowledge, facts, and concepts.
