Study Notes

Learning Outcomes

  • The three components of memory are encoding, storage, and retrieval
  • Memory models provide frameworks for understanding how memory works
  • There are different types of memory with unique characteristics
  • Forgetting can be caused by various factors
  • Common memory disorders are described

Encoding

  • Encoding is the process of transforming incoming information into a memory representation
  • Attention is crucial for encoding, with divided attention hindering memory formation
  • Three types of encoding are shallow (structural), intermediate (phonemic), and deep (semantic)
  • Deeper encoding leads to longer-lasting memory codes, facilitating better recall

Storage

  • Storage refers to the maintenance of encoded information in memory
  • Information processing models, inspired by computers, are influential frameworks
  • The Atkinson & Shiffrin Multi-Store Model proposes three distinct memory stores: sensory memory, short-term memory (STM), and long-term memory (LTM).
  • These stores are not physical structures but metaphorical representations of memory functions

Sensory Memory

  • Sensory memory briefly holds incoming auditory, tactile, or visual information
  • It acts as a fleeting “echo” allowing for initial recognition and attention redirection

Short-Term Memory (STM)

  • STM has a limited capacity of around 7±2 units of information, known as Miller's Law.
  • New information can displace existing information within STM, which has a duration of 20-30 seconds.
  • Rehearsal extends the duration of information in STM.
  • Baddeley and Hitch's working memory model expands on STM, proposing a more dynamic and active system

Long-Term Memory (LTM)

  • LTM has unlimited capacity and indefinite duration, potentially lasting permanently.
  • Debate exists around the concept of “flashbulb” memories and evidence of decay, interference, or retrieval failure.
  • LTM is organized into different systems including: declarative (explicit) memory, procedural (implicit) memory.
  • Declarative memory is further subdivided into semantic memory (general knowledge) and episodic memory (dated personal experiences).

Retrieval

  • Retrieval involves accessing information from memory.
  • It's not an exact replica of the original experience but can be distorted by unrelated events.
  • Misleading post-event information can impact memory, as exemplified by the misinformation effect, affecting eyewitness testimony.

Factors Affecting Retrieval

  • Serial-Position Effect: Recall is better for information presented at the beginning (LTM) and end (WM) of a sequence.
  • Time: Forgettting occurs most rapidly after memorization.
  • Meaningfulness and Connectedness: Meaningful and connected information is easier to recall
  • Retrieval Cues: Hinweise and reinstating context improve recall.
  • Retrieval Methods: Recall, recognition, re-learning, and reconstruction are different approaches to retrieving information.

Reasons for Forgetting

  • Ineffective Encoding: Lack of attention can lead to information not being encoded properly.
  • Decay: Memory fades over time due to physiological deterioration, with limited empirical support.
  • Interference: Competition from other information can cause forgetting (retroactive interference or proactive interference).
  • Retrieval Failure: The "tip-of-the-tongue" phenomenon illustrates retrieval difficulties.
  • Working Memory (WM) Capacity: Presenting too much information at once overwhelms WM.

Practical Implications for Personal Studies

  • Maximize Encoding Capacity: Minimize interference and maximize attention to improve encoding.
  • Be Mindful of WM Capacity: Limit information presented at once.
  • Space Learning: Distribute practice over time to consolidate learning.
  • Avoid Shallow Processing: Engaging in deep processing through elaboration, visualization, paraphrasing, and explanation leads to better retention.
  • Use Techniques to Assist Recall: Employ strategies like reconstruction, reinstating context, chunking information, and using retrieval cues.

Practical Implications for Medical Professionals

  • Present information in manageable chunks.
  • Utilize clear categorization and chunking of information, emphasizing important concepts.
  • Give key information early and summarize at the end (primacy and recency effects).
  • Facilitate encoding from WM to LTM by encouraging frequent repetition of key information.
  • Deepen encoding through meaningful explanation, concrete examples, and visual aids.
  • Connect new information to patients' existing knowledge and prior learning.
  • Provide recall cues such as diagrams, visuals, leaflets, and written instructions.
  • Consider using visual aids, explanations, and examples for patient education to enhance recall.
  • Explain rationales for treatments and procedures to facilitate better understanding and compliance.

Applying Learning to Personal Experiences

  • Analyze your own memory lapse to identify the type of memory involved (sensory, STM, or LTM).
  • Determine likely causes of the lapse based on discussed forgetting factors.
  • Explore potential strategies to enhance future recall of information, drawing on the principles described in this lecture.

Key Components of Memory

  • Memory is comprised of Encoding, Storage, and Retrieval.
  • Encoding is how information gets into memory.
  • Attention is crucial for successful encoding.
  • Storage is how information is maintained in memory.
  • Retrieval is how information is recovered from memory.

Memory Models

  • Information processing models are based on computer metaphors.
  • The multi-store model is the most influential theory of memory.
  • Atkinson and Shiffrin proposed the multi-store model, which includes three stores: sensory memory, short-term memory (STM), and long-term memory (LTM).
  • These stores are not physical; they are theoretical.

Sensory Memory

  • Information from sensory experiences is kept momentarily, just long enough for processing and attention redirection.
  • Sensory memory is likened to an "echo" or a "visual after-image."

Short-Term Memory (STM)

  • STM has limited capacity; 7±2 units of information can be stored (Miller's Law).
  • New information can displace existing information in STM.
  • STM has a limited duration of 20-30 seconds.
  • Rehearsal extends the duration of information in STM.

STM as "Working Memory"

  • This theory by Baddeley and Hitch (1974) describes STM as more than just a temporary storage space.
  • Working memory encompasses not only sensory information but also cognitive processes like manipulation and reasoning.

Long-Term Memory (LTM)

  • LTM has unlimited capacity and stores information indefinitely, despite some debate on the permanence of memories.
  • LTM has several systems organized in a logical framework.
  • Declarative: Explicit knowledge about facts and events:
    • Semantic: General knowledge (e.g., capital of France).
    • Episodic: Dated recollections of personal experiences (e.g., first date).
  • Procedural: "How-to" knowledge; actions, skills, conditioned responses (e.g., riding a bicycle).

Reasons for Forgetting

  • Ineffective Encoding: Insufficient attention can result in information not being encoded properly.
  • Decay: Memory fades due to the passage of time; however, this theory lacks much empirical support.
  • Interference: New information can interfere with the retention of older information (retroactive interference), while older information can interfere with new information (proactive interference).
  • Retrieval Failure: Information is present in LTM but not accessible; "tip-of-the-tongue" phenomenon is an example.
  • Working Memory Capacity: Limitation in the amount of information that can be processed simultaneously (e.g., providing too much medical information at once).

Enhancing Memory

  • Minimize interference and maximize attention to improve encoding capacity.
  • Chunk information into meaningful categories.
  • Space learning; avoid cramming.
  • Avoid shallow processing, such as simple rereading.
  • Use deep processing strategies:
    • Elaborate on information, draw diagrams, provide examples, paraphrase, explain concepts.
    • Connect information to existing knowledge.
  • Facilitate Recall: Employ retrieval cues (e.g., visuals, information leaflets), consider the order of presentation, and use techniques like reconstruction.
  • Reinstate context: Returning to the environment where learning happened can aid recall.

Clinical Case: Clive Wearing

  • Clive Wearing's case demonstrates the impact of memory impairments on different aspects of memory functions.
  • Despite an intact sensory memory, Clive's ability to form new memories was severely compromised, affecting his STM and LTM capacity.

Practical Implications for Studying

  • Maximize encoding capacity: Minimize distractions and focus attention.
  • Be mindful of working memory capacity: Chunk information and avoid overload.
  • Space learning: Avoid cramming and use spaced repetition techniques.
  • Avoid shallow processing: Engage in deeper processing strategies (e.g., concept mapping, elaborating).
  • Use techniques for retrieval: Construct retrieval cues, utilize reconstruction, and reinstate context.

Learning Outcomes

  • Identify the 3 key components of memory: encoding, storage, and retrieval.
  • Outline models of memory: Atkinson-Shiffrin (modal model), levels of processing theory, and multiple memory systems.
  • Describe the characteristics of each memory type: sensory, short-term, working, and long-term memory, including declarative (episodic and semantic) and procedural memory.
  • Discuss reasons for forgetting: encoding failure, decay, interference, retrieval failure, and motivated forgetting.
  • Describe common memory disorders: amnesia (retrograde, anterograde, post-traumatic), and memory loss in Alzheimer's disease.

Encoding

  • Attention is critical for encoding.
  • Divided attention can impede encoding.
  • Types of 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

  • Multiple memory systems are organized in a logical framework:
    • Declarative memory (explicit):
      • Semantic memory (general knowledge): examples include knowing the capital of France or the rules of chess.
      • Episodic memory (dated recollections of personal experiences): examples include remembering your first day of school or your first date.
    • Procedural memory (implicit): examples include riding a bicycle or typing on a keyboard.

Retrieval

  • Information retrieved from memory might not be an exact replica of the original.
  • Information can be distorted by unrelated events.
  • The misinformation effect: misleading post-event information can distort memory, potentially affecting eyewitness testimony (Loftus & Palmer, 1974).

Factors Affecting Retrieval

  • Serial-Position effect: better recall for information at the beginning (long-term memory) and the end (working memory).
  • Most forgetting occurs immediately after memorization.
  • Ebbinghaus (1885): memory for "nonsense" syllables decays over time (forgetting curve).
  • Meaningfulness and connectedness increase recall.
  • Retrieval cues help to access information.
  • Retrieval methods:
    • Recall: no cues, most difficult.
    • Recognition: select from an array of options.
    • Relearning: effort saved on relearning indicates the extent of initial learning.
    • Reconstruction: combines 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 with time due to deterioration of neural connections - not much empirical support.
  • Interference: competition from other information:
    • Retroactive interference: new information impairs old information.
    • Proactive interference: old information interferes with new information.
  • Retrieval failure: "Tip-of-the-tongue" phenomenon; context similar to encoding can improve retrieval.
  • Motivated forgetting: Freud - people repress unpleasant memories into the unconscious mind.

Clinical Disorders of Memory

  • Amnesia: partial or total memory loss.
    • Retrograde amnesia: inability to remember events prior to the onset (retrieval failure).
    • Anterograde amnesia: inability to take in new information or remember day-to-day events (consolidation failure).
    • Post-traumatic amnesia: combination of both retrograde and anterograde amnesia; the period of retrograde amnesia shrinks while the period of anterograde determines the severity of the head injury.
  • Causes of amnesia: brain injury, drugs, encephalitis, electroconvulsive therapy (ECT), alcoholism (Korsakoff's Syndrome), lack of stimulation, severe emotional trauma, Alzheimer's disease.

Memory Loss in Alzheimer's Disease

  • Working memory: initially intact but becomes more sensitive to distraction.
  • Long-term memory:
    • Procedural memory: relatively intact.
    • Declarative memory:
      • Semantic memory: difficulty with language and recall of conceptual information, often occurring years before diagnosis.
      • Episodic memory: among the first signs and symptoms (forgetfulness, missed appointments); Ribot's law - recent memories are more likely to be lost; deficits in consolidation from short-term to long-term memory.

Practical Implications

  • Professional:

    • Understand factors affecting recall to help patients with memory problems.
    • Consider situational factors that may contribute to memory difficulties (stress, distraction).
    • Refer patients for cognitive impairment screening if needed.
    • Facilitate patient recall:
      • Minimize distractions.
      • Chunk information into categories.
      • Present important information early and summarize at the end.
      • Repeat key information to promote rehearsal.
      • Make information meaningful and connect it to existing knowledge.
      • Provide retrieval cues.
  • Personal:

    • Maximize encoding capacity: minimize interference and maximize attention.
    • Be mindful of working memory capacity.
    • Space learning and avoid cramming.
    • Avoid shallow processing (rereading without comprehension).
    • Use strategies for deep processing: elaborating, drawing diagrams, providing examples, paraphrasing, explaining concepts.
    • Build connections with existing knowledge.
    • Use recall techniques: reconstruction, reinstating context, chunking information, thinking of cues.
