Study Notes

Memory Defined

  • Memory is the process of encoding, storing, and retrieving information.

Memory Processes

  • Encoding: Recording information in a usable form for memory.
  • Storage: Maintaining encoded material in memory.
  • Retrieval: Locating and bringing stored information to awareness.

Example: Trivial Pursuit

  • Encoding: Properly recording information (e.g., Mumbai's location).
  • Storage: Retaining encoded info.
  • Retrieval: Recalling info when needed (e.g., location of Mumbai)

Analogy to Computer

  • Encoding: Input through keyboard.
  • Storage: Information saved on the hard drive.
  • Retrieval: Accessing information via software.

Three-System Model of Memory

  • Sensory Memory: Initial, brief storage of sensory input (iconic, echoic).
  • Short-Term Memory (STM): Holds information temporarily (15-25 seconds), and organized by meaning.
  • Long-Term Memory (LTM): Stores info permanently, potentially difficult to retrieve.

Movement Through Memory Systems

  • Information moves from sensory memory to STM, then to LTM if rehearsed.

Sensory Memory

  • Iconic Memory (visual): Lasts approximately 1 second.
  • Echoic Memory (auditory): Lasts up to 4 seconds.
  • Purpose: Allows time to process and decide if information is worth storing.

Short-Term Memory (STM)

  • Capacity: Approximately 7 +/-2 chunks of information.
  • Duration: Short-lived (20 seconds) without rehearsal.
  • Purpose: Temporary storage before information is processed or discarded.

Rehearsal

  • Simple Rehearsal: Repeating information without elaborating.
  • Elaborative Rehearsal: Organizing and considering information in a meaningful way to enhance LTM transfer.

Long-Term Memory (LTM)

  • Declarative Memory (Explicit): Facts and events, further divided into...
    • Semantic Memory: General knowledge and facts (e.g., rules of logic, ZIP codes).
    • Episodic Memory Events tied to specific times, places, contexts (e.g., first day of college).
  • Procedural Memory (Implicit): Skills and habits (e.g., riding a bike). Cannot be verbally described but can be performed.

Memory Retrieval Issues

  • Encoding, storage, or retrieval problems can affect memory recall.

Working Memory (WM)

  • Functions as an active workspace in the brain, temporarily holding, manipulating, and rehearsing information.
  • Components:
    • Central Executive Processor: Reasoning, decision making, planning.
    • Visual Store: Stores visual and spatial information.
    • Verbal Store: Stores language-based information.
    • Episodic Buffer: Stores information about events.

Working Memory Capacity Limitations

  • Can only hold 3-4 chunks of information at a time.

Working Memory & Awareness

  • High cognitive effort during working memory tasks can decrease awareness of surroundings.
  • Example: Using a phone while driving.

Working Memory & Stress

  • Stress can diminish WM capacity and effectiveness.

Long-Term Memory (LTM)

  • Stores information persistently, with almost unlimited capacity.
  • Evidence for LTM: Includes brain damage cases exhibiting retention in past memories while losing ability to form new memories.
  • List Recall:
    • Primacy Effect: Items at the beginning of a list are better remembered.
    • Recency Effect: Items at the end of a list are better remembered.

Mnemonics (Memory Strategies)

  • Techniques for improving memory retention.
  • Examples: associating musical notes with words, rhymes.

Flashbulb Memories

  • Vivid recollections of important or surprising events.
  • Characteristics: strong emotional connection, vivid imagery, detailed recollections, BUT inaccuracies can occur over time.

Tip of the Tongue Phenomenon (TOT)

  • Temporary inability to recall a piece of information.

Levels of Processing Theory

  • Deeper processing leads to stronger memory.
  • Shallow: Physical characteristics (e.g., letters, words).
  • Intermediate: Meaning of items, units, sounds.
  • Deep: Meaning plus associations (e.g., prior knowledge).

Explicit Memory

  • Conscious recollection of information.
  • Examples: names, dates, facts, events.

Implicit Memory

  • Unconscious recollection of information influencing behavior.
  • Examples: automatically avoiding an obstacle, feelings towards someone even without conscious recollection of why.

Priming

  • Exposure to a stimulus (a prime) enhances recall of related information.

Memory Failures

  • Forgetting due to Interference:
    • Proactive: Previously learned info disrupts learning newer info.
    • Retroactive: More recently learned info disrupts recall of earlier info.
  • Forgetting due to Encoding Failure: Insufficient attention during information processing.
  • Forgetting due to Decay: Loss of information with time.

Memory Dysfunctions

  • Alzheimer's Disease: Progressive and irreversible brain disorder causing cognitive decline.
  • Amnesia: Memory loss without other cognitive impairments.
  • Retrograde Amnesia: Memory loss for events before the traumatic incident.
  • Anterograde Amnesia: Inability to form new memories after the incident.

Constructive Processes in Memory

  • Memory relies on schemas (personal experiences, biases) to reconstruct past events and interpretations. Memories are not exact copies of events, but reconstructions.

Children's Memory Reliability

  • More susceptible to external influences compared to adults. Carefully handling children's testimony is vital to minimize suggestibility.

Memory and Culture

  • Similar memory processes exist across cultures, differences exist in memory practices.

Repressed & False Memories

  • Controversy around the existence of repressed memories. Difficult to distinguish repressed traumatic memories from recalled false memories that are not real. Some suggest memories can be constructed or distorted.
