Study Notes

Memory

Components of Memory:
- Encoding: How information gets into memory
  - Attention is critical for encoding
  - Divided attention can negatively impact memory
- Storage: How information is maintained in memory
- Retrieval: How information is recovered from memory
  - Retrieval is not perfect, and information can be distorted

Models of Memory

Atkinson and Shiffrin's Multi-Store Model:
- Proposed by Atkinson and Shiffrin in the 1970s
- A model of memory storage with three key components:
  - Sensory Memory: Briefly stores sensory information (milliseconds to seconds)
  - Short-Term Memory (STM): Holds a limited amount of information for about 20 seconds
  - Long-Term Memory (LTM): Stores information for indefinite periods with unlimited capacity

Memory Types

Sensory Memory:
- Briefly stores sensory information, such as auditory, visual, or tactile information
- Allows us to perceive and be aware of stimuli
Short-Term Memory (STM):
- Also known as working memory
- Has a limited capacity, often referred to as Miller's Law (7 ± 2 units of information)
- Rehearsal helps extend the duration of information in STM
**Long-Term Memory (LTM): **
- Stores information for extended periods with unlimited capacity
- Multiple memory systems within LTM include:
  - Declarative Memory: Explicit knowledge, including:
    - Semantic Memory: General knowledge (e.g. capital of France)
    - Episodic Memory: Personal experiences (e.g. first date)
  - Procedural Memory: Implicit knowledge, including actions, motor skills, and conditioned responses (e.g., riding a bicycle)

Reasons for Forgetting

Ineffective Encoding:
- Information not encoded properly due to lack of attention
Decay:
- Memory fades over time
- Limited empirical support
Interference:
- Competition from other information
  - Retroactive Interference: New information interferes with retention of old information
  - Proactive Interference: Old information interferes with retention of new information
Retrieval Failure:
- Difficulty accessing information that has been stored in memory
  - "Tip-of-the-tongue" phenomenon
Working Memory (WM) Capacity:
- Don't overload WM with too much information at once
- Chunk information into meaningful categories to increase WM efficiency

Practical Implications: Study Skills

Maximise Encoding Capacity:
- Minimize interference and maximize attention
Mindful of WM Capacity:
- Avoid overloading WM
Space Learning:
- Avoid cramming and space out learning sessions for better retention
Avoid Shallow Processing:
- Deepen understanding by elaborating on concepts, drawing diagrams, and paraphrasing information
Use Techniques for Deep Processing:
- Make connections to existing knowledge to enhance learning
Use Retrieval Techniques:
- Context reinstatement, chunking information, and using cues can help with retrieval

Memory Storage

The invention of computers influenced models of memory storage.
Atkinson & Shiffrin (1970’s) proposed the Multi-Store Model, a widely accepted model suggesting that memory has three separate stores: Sensory Memory, Short-Term Memory (STM), and Long-Term Memory (LTM).
These stores are not physical structures but rather conceptual representations.

Sensory Memory

Briefly holds auditory, tactile, or visual information, just long enough for recognition and attention redirection.
Acts like an “echo” rather than a storage unit, like a visual “after-image”.

Short-Term Memory (STM)

Limited capacity, holding approximately 7±2 units of information (Miller’s Law).
New information can displace existing information in STM.
Limited duration, lasting around 20-30 seconds.
Rehearsal (verbal repetition) extends the duration of information in STM.

Working Memory

Baddeley & Hitch (1974) expanded on STM, introducing the concept of Working Memory.
Working memory is not simply a rehearsal buffer for sensory information, but actively manipulates and processes information.

Long-Term Memory (LTM)

Unlimited capacity and indefinite duration.
Debates exist regarding the permanence of LTM, with evidence suggesting decay, interference, or retrieval failure.
LTM is organized into logical frameworks, encompassing Declarative memory (facts, explicit knowledge; including Semantic and Episodic) and Procedural memory (actions, skills, conditioned responses).

Reasons for Forgetting

Information lost if not encoded properly—inability to remember due to lack of attention.
Decay—memory fades over time, but little empirical support exists.
Interference—competition from other information, including retroactive interference (new info affecting old) and proactive interference (old info affecting new).
Retrieval failure—“tip-of-the-tongue” phenomenon; retrieval is easier when context is similar to encoding context.
Motivated forgetting—Freud’s concept of repression where unpleasant or traumatic memories are suppressed.

Memory Disorders

Amnesia: Partial or total memory loss.
- Retrograde Amnesia: Inability to recall events before the onset; retrieval failure.
- Anterograde Amnesia: Difficulty forming new memories; consolidation failure.
- Post-Traumatic Amnesia: Combines both retrograde and anterograde amnesia; duration of anterograde amnesia helps categorize head injury severity.
Alzheimer’s Disease:
- Affects working memory, increasing sensitivity to distractions.
- Procedural memory is relatively intact, but declarative memory (semantic and episodic) is impaired.
- Semantic memory: Difficulty with language and recall of conceptual information.
- Episodic memory: Difficulty with remembering personal experiences, often an early symptom.
- Ribot’s Law states that recent memories are more vulnerable to loss.
- Difficulty in consolidating information from STM to LTM.

Practical Implications: Professional

Understand memory limitations to improve patient care, including:
- Recall is crucial for patient adherence to treatment plans.
- Consider factors affecting encoding and retrieval to facilitate patient learning and understanding.
- Avoid presenting excessive information at once.
- Chunking information into categories helps organize and recall.
- Repeating key information facilitates rehearsal and transfer to LTM.
- Relate new information to existing knowledge and past experiences.
- Provide recall cues like diagrams, leaflets, and written instructions.

Practical Implications: Personal

Study skills to enhance learning and memory:
- Minimize distractions to maximize attention during learning.
- Space out learning to avoid mass practice, promoting consolidation.
- Engage in deep processing techniques like elaborating on information, drawing diagrams, and explaining concepts.
- Use techniques to improve recall, such as reconstruction, reinstating context, and creating cues.

Memory: Key Components and Models

Memory is a complex cognitive function that involves several key processes: encoding, storage, and retrieval.
Encoding refers to how information is initially processed and entered into memory. It can be shallow (structural), intermediate (phonemic), or deep (semantic), with deeper levels resulting in stronger and more lasting memory codes.
Storage refers to how information is maintained in memory over time. The multi-store model proposed by Atkinson and Shiffrin (1970s) suggests three distinct stores:
- Sensory Memory: Holds brief sensory information for milliseconds to seconds.
- Short-Term Memory (STM): Holds limited information (7±2 units) for 20-30 seconds, and can be extended through rehearsal.
- Long-Term Memory (LTM): Holds information indefinitely with an unlimited capacity.
Retrieval refers to bringing stored information back into conscious awareness.

Factors Influencing Retrieval

Serial-Position Effect: Information at the beginning and end of a sequence is better remembered than information in the middle.
Time: Most forgetting occurs immediately after memorization, but this rate slows down over time.
Meaningfulness: Information that is meaningful and connected to existing knowledge is easier to recall.
Retrieval Cues: Hints and contextual cues can facilitate retrieval.
Retrieval Methods: Different methods have varying levels of difficulty:
- Recall: Retrieving information without any cues (most difficult).
- Recognition: Identifying information from a set of options.
- Re-learning: Measuring the time saved when relearning previously learned information.
- Reconstruction: Combining stored information with other available information.

Reasons for Forgetting

Ineffective Encoding: Information is not encoded properly due to lack of attention.
Decay: Memory fades over time due to physiological changes, but this has limited evidence.
Interference: Competition from other information can impair memory:
- Retroactive Interference: New information interferes with old information.
- Proactive Interference: Old information interferes with new information.
Retrieval Failure: Information is present in memory but cannot be accessed due to insufficient cues.
Motivated Forgetting: Unpleasant or embarrassing memories are consciously repressed (Freud).

Common Memory Disorders

Amnesia: Partial or total memory loss:
- Retrograde Amnesia: Inability to recall information before the onset of amnesia.
- Anterograde Amnesia: Inability to form new memories after the onset of amnesia.
- Post-Traumatic Amnesia: Combines both retrograde and anterograde amnesia.
Alzheimer's Disease: Progressive neurodegenerative disorder characterized by memory impairment and cognitive decline.
- Early Stages: Working memory is intact but sensitive to distraction.
- Later Stages: Difficulty with language and recall of conceptual information, episodic memory deficits, and consolidation issues.
Korsakoff's Syndrome: Memory disorder caused by chronic alcohol abuse.
