    Study Notes

    Memory Storage

    • Influenced by the invention of computers and information processing models.
    • Atkinson & Shiffrin (1970’s) proposed the Multi-Store Model:
      • Most influential theory of memory
      • Three separate stores:
        • Sensory Memory
        • Short-Term Memory (STM)
        • Long-Term Memory (LTM)
      • Not physical structures! – Computer metaphor

    Memory Store Characteristics

    • Sensory Memory:
      • Briefly holds auditory, tactile and visual information (milliseconds or seconds).
      • Just enough time to recognize and direct attention.
      • Example: Visual "after-image".
    • Short-Term Memory (STM):
      • Limited capacity:
        • 7±2 units of information (Miller’s Law)
        • New information displaces existing information.
      • Limited duration:
        • 20-30 seconds
        • Rehearsal (e.g., verbal repetition) extends duration.

    Working Memory:

    • STM is also known as Working Memory (Baddeley & Hitch, 1974).
    • Working memory is more than just sensory information or a rehearsal buffer.

    Long-Term Memory (LTM)

    • Unlimited capacity.
    • Indefinite duration:
      • Permanent? “Flashbulb” memory debate.
      • Evidence of decay, interference, and/or retrieval failure.
    • Multiple memory systems:
      • Declarative:
        • Semantic (general knowledge, e.g., the capital of France).
        • Episodic (dated recollections of personal experiences, e.g., first boyfriend/girlfriend).
      • Procedural (actions, perceptual-motor skills, conditioned responses, e.g., riding a bicycle).

    Retrieval

    • How information is recovered from memory.
    • Inaccurate and easily distorted by:
      • Unrelated events.
      • Misinformation effect:
        • Misleading post-event information.
        • Example: Question wording.
        • Implications for eyewitness testimony (Loftus & Palmer, 1974).

    Factors Affecting Retrieval

    • Order of Encoding:
      • Serial-Position effect:
        • Better recall of information at the start (LTM).
        • Better recall of information at the end (Working Memory).
    • Time:
      • Most forgetting occurs immediately after memorisation.
      • Ebbinghaus (1885): ‘nonsense’ syllables (e.g., XOS).
    • Meaningfulness:
      • Increased meaningfulness promotes recall.
    • Connectedness:
      • Relating new information to existing knowledge increases recall.
    • Retrieval Cues:
      • Hints and reinstating context cues improve retrieval.
    • Retrieval Methods:
      • Recall: No cues, highest difficulty.
      • Recognition: Selecting from a set of options, easier than recall.
      • Re-learning: Effort saved on the second learning indicates the extent of the first learning.
      • Reconstruction: Combining stored information with other available information.

    Reasons for Forgetting

    • Ineffective Encoding:
      • Information not encoded properly due to lack of attention (pseudo-forgetting).
    • Decay:
      • Memory fades over time due to decay in physiological mechanisms.
      • Not much empirical support.
    • Interference:
      • New information impairs retention of old information (retroactive interference).
      • Old information interferes with the retention of new information (proactive interference).
    • Retrieval Failure:
      • “Tip-of-the-tongue” phenomenon.
      • Retrieval often best when context is similar to the encoding context.
    • Motivated Forgetting:
      • Freud: People bury unpleasant memories in the unconscious mind (repression).

    Memory Disorders

    • Amnesia: Partial or total memory loss.
      • Retrograde Amnesia: Inability to remember events that happened before the onset.
      • Anterograde Amnesia: Inability to acquire new factual information or remember day-to-day events.
      • Post-traumatic Amnesia: Combines both retrograde and anterograde amnesia.

    Causes of Amnesia

    • Brain Injury.
    • Drugs (e.g., BZDs, anaesthetics).
    • Encephalitis.
    • Electroconvulsive therapy (ECT).
    • Alcoholism (Korsakoff’s Syndrome).
    • Lack of stimulation.
    • Severe emotional trauma.
    • Alzheimer’s disease:
      • Approximately 50% of people by age 85.
      • Not normal aging.

    Memory Loss in Alzheimer's Disease

    • Working memory:
      • Relatively intact initially but increased sensitivity to distraction.
    • Long-term memory:
      • Procedural relatively intact.
      • Declarative (Semantic):
        • Difficulty with language and recall of conceptual information (e.g., a clock).
        • Can occur years before diagnosis.
      • Declarative (Episodic):
        • Among the first signs and symptoms (e.g., “forgetfulness,” missed appointments).
        • Ribot’s law: Recent memories are more likely to be lost.
        • Deficits in consolidation from short-term to long-term memory.
    • Implications:
      • Vivid memories can be confused with psychotic symptoms.
      • Therapeutic application: Reminiscence therapy.

    Practical Implications: Professional

    • Understand factors that affect recall to:
      • Gain insight into why patients do not recollect information or present with memory problems.
      • Not always age-related!
      • Referral and/or screening for cognitive impairment.
      • Situational factors may play a role (e.g., stress, distraction).
    • Recall is crucial for good patient adherence.

    Practical Implications: Personal (Study Skills)

    • Maximize encoding capacity:
      • Minimize interference.
      • Maximize attention.
    • Be mindful of working memory capacity.
    • Space learning; avoid "mass practice":
      • Relearning helps consolidation.
    • Avoid shallow processing:
      • Do not just read and reread information.
    • Use deep processing strategies:
      • Elaborate on information, draw diagrams, think of examples, paraphrase information, and explain concepts to a friend.
      • Build connections with existing knowledge.
    • Use techniques to improve recall:
      • Reconstruction, reinstating context, chunking information, and thinking of cues.

    Memory and Its Components

    • Memory is not an entity, but a process
    • 3 key components: Encoding, Storage, Retrieval
    • Clive Wearing case demonstrates the fragility of memory
    • Encoding: how information enters memory. Attention is key for effective encoding
    • Levels of Processing Theory: (Craik & Lockhart, 1972)
      • Shallow: structural (physical appearance)
      • Intermediate: Phonemic (sound)
      • Deep: Semantic (meaning)
    • Deeper levels of processing lead to longer lasting memory codes
    • Storage: how information is maintained in memory
    • Multi-Store Model of Memory (Atkinson & Shiffrin, 1970’s)
      • 3 distinct stores: Sensory, Short-Term, Long-Term
      • Sensory Memory: Brief retention of sensory information
        • Auditory, tactile, visual
        • Like an echo
      • Short-Term Memory (STM): Limited capacity (7±2 units of information) and duration (20-30 seconds)
        • Rehearsal extends duration
      • Working Memory (Baddeley & Hitch, 1974) focuses on processing and manipulating information
        • Not just a simple store
      • Long-Term Memory (LTM): Unlimited capacity and indefinite duration
        • Information is potentially permanent

    Factors Influencing Retrieval

    • Serial Position Effect: Easier to recall information at the beginning (LTM) and end (WM) of a list
    • Time: Most forgetting happens immediately after memorization
    • Meaningfulness: Increases recall
    • Connectedness: Increases recall by relating new information to existing knowledge
    • Retrieval Cues: Hints that help recall
    • Retrieval methods:
      • Recall: No cues (most difficult)
      • Recognition: Selecting from a list
      • Re-learning: Effort saved during second learning
      • Reconstruction: Combining stored information with other information

    Reasons for Forgetting

    • Ineffective Encoding: Information not encoded correctly due to lack of attention
    • Decay: Memory fades over time due to decay in physiological mechanisms (not much empirical support)
    • Interference: Competition from other information
      • Retroactive: New information impairs old
      • Proactive: Old information interferes with new
    • Retrieval Failure: Information is present but cannot be accessed
    • Motivated Forgetting: (Repression: Freud) - Painful or embarrassing memories buried in the unconscious

    Memory Disorders

    • Amnesia: Partial or complete memory loss
      • Retrograde: Inability to recall events prior to onset
      • Anterograde: Inability to form new memories
      • Post-traumatic: Combines both
    • Alzheimer’s Disease: Progressive neurodegenerative disease impacting memory
      • Working Memory: Intact initially but becomes sensitive to distraction
      • Long-Term Memory
        • Procedural: Relatively intact
        • Declarative
          • Semantic: Difficulty with language and conceptual information
          • Episodic: Difficulty with personal events (among the first signs)

    Practical Applications (Healthcare)

    • Patient Memory and Recall:
      • Understanding factors influencing recall can help explain patient memory problems
      • Consider referral or cognitive impairment testing
      • Facilitate recall by:
        • Minimizing interference and maximizing attention
        • Chunk information
        • Repeat key information
        • Make information meaningful by explaining rationales and using examples
        • Provide retrieval cues

    Practical Applications (Study Skills)

    • Encoding:
      • Minimize interference
      • Space your learning (avoid cramming)
      • Use deep processing (élaboration, paraphrasing, explaining)
    • Retrieval:
      • Use retrieval cues
      • Practice!

    Key Components of Memory

    • The three key components of memory are encoding, storage, and retrieval.
    • Encoding is how information enters memory.
    • Storage is how information is maintained in memory.
    • Retrieval is how information is accessed from memory.

    Levels of Processing Theory

    • Deeper levels of processing (semantic) generally lead to longer lasting memory codes and better recall.
    • Shallower levels of processing (structural and phonemic) are less effective for long-term memory.

    Models of Memory

    • Multi-store Model proposes three separate stores for memory: sensory, short-term, and long-term.
    • Sensory Memory is the brief storage of information for a few milliseconds or seconds, depending on the stimulus type.
    • Short-Term Memory (STM) is the area where conscious processing takes place.
    • Long-Term Memory (LTM) is the storehouse of information that can last indefinitely.

    Characteristics of Memory Types

    • Sensory memory is a very brief echo of information, lasting only long enough to be recognized and directed.
    • Short-term memory has a limited capacity (around 7±2 units of information) and duration (20-30 seconds). Rehearsal can extend the duration of information in STM.
    • Working memory is a more complex concept than STM and involves more than just sensory information and rehearsal. It is responsible for active manipulation and processing of information in the short-term.
    • Long-term memory has an unlimited capacity and indefinite duration.

    Retrieval

    • Serial-Position Effect: Items at the beginning and end of a list are better remembered than those in the middle. This is likely due to primacy effects (information at the beginning has a chance to be transferred to LTM) and recency effects (information at the end is still in working memory).
    • Time: Most forgetting occurs immediately after information is memorized, and then plateaus.
    • Meaningfulness: Information that is meaningful is more easily remembered.
    • Connectedness: Information that connects to existing knowledge is more easily remembered.
    • Retrieval Cues: Hints and reinstating contextual cues can help to recall information.

    Why We Forget

    • Ineffective encoding: Information not encoded properly due to lack of attention, resulting in pseudo-forgetting.
    • Decay: Memories fade with time due to decay in physiological mechanisms.
    • Interference: Competition from other information, such as new information interfering with old information, or old information interfering with new information.
    • Retrieval Failure: Difficulty in retrieving information. The "tip-of-the-tongue" phenomenon is an example.
    • Motivated Forgetting: The theory that individuals repress unpleasant memories, pushing them into the unconscious mind.

    Memory Disorders

    • Amnesia: Loss of memory.
      • Retrograde Amnesia: Inability to remember events that happened prior to the onset of amnesia.
      • Anterograde Amnesia: Inability to acquire new memories.
      • Post-Traumatic Amnesia: A combination of retrograde and anterograde amnesia, often following a head injury.
    • Alzheimer’s Disease: A progressive brain disorder that affects working memory, long-term memory (both semantic and episodic), and cognitive function.

    Practical Implications

    • Professional
      • It is important to be aware of factors that affect recall to understand why patients may have difficulty remembering information or present with memory problems.
      • Referral and/or screening for cognitive impairments are necessary.
      • Patients’ recall is crucial for adherence to medical instructions.
      • Facilitate encoding by presenting information in chunks, repeating key information, and making it meaningful.
      • Provide retrieval cues to support patient recall.
    • Personal
      • Attention and minimizing interference are critical for encoding information.
      • Utilize strategies for deep processing such as elaborating on information, drawing diagrams, and creating connections to existing knowledge.
      • Use techniques to improve recall such as chunking information, using mnemonics, and practicing the retrieval process.
