Memory Processes and Structures

Working Memory

  • Alternate Name: Working memory is also referred to as short-term memory.

Memory Processes in the Information-Processing Model

  • Three Processes of Memory: The three processes crucial for memory in the information-processing model are:
    • Encoding: The process of transforming incoming information into a form that can be stored in memory.
    • Storage: The method of maintaining information over time.
    • Retrieval: The act of recalling or accessing the stored information.
    • Non-Process: Recollection is not considered one of the three main processes.

Source Misattribution

  • Definition: The inability to distinguish what you originally experienced from what you heard or were told later about an event is termed as source misattribution.
    • Related Terms:
    • Source misinformation: Providing incorrect details about a memory.
    • Source confusion: Previously experienced information being confused with new sensory information.
    • Source bias: The influence of false information on memory recall.

Long-Term Memory Limits

  • Capacity of Long-Term Memory: Long-term memory has no apparent limit, meaning it can store vast amounts of information indefinitely.

Types of Long-Term Memory

  • **Types and Characteristics: **
    • Semantic Memory (E): Contains general knowledge, facts, rules, and concepts.
    • Implicit Memory Types:
    • Procedural Memory (I): Skills and actions.
    • Classical Conditioning (I): Learning through association.
    • Priming (I): Improved identification of objects or words.
    • Episodic Memory (E): Contains personal experiences and specific events.

Recall vs. Recognition

  • Recall: The ability to retrieve and reproduce previously learned information independently (e.g., free response questions).
  • Recognition: The ability to identify previously encountered information among options (e.g., multiple-choice questions).

Brain Structures and Their Functions

  • Basal Ganglia (3): Processes and stores information obtained from classical conditioning.
  • Amygdala (2): Strengthens memory for emotionally charged events.
  • Cerebellum (1): Helps execute motor movements.

Long-Term Potentiation (LTP)

  • Concept Summary: Long-term potentiation can be summarized as:
    • Neurons that fire together wire together (B): This concept illustrates the physical basis for learning and memory.

Maintenance Rehearsal vs. Elaborate Rehearsal

  • False Statement: Maintenance rehearsal is not more effective than elaborate rehearsal in retaining information for prolonged periods.
  • Rehearsal Types Defined:
    • Maintenance rehearsal: Involves rote repetition of information.
    • Elaborate rehearsal: Involves connecting new information to existing information or concepts to aid retention.

Context-Dependent Memory

  • Definition: Context-dependent memory occurs when recall is better when tested in the same context or environment (A) where the information was initially learned.
    • Antithesis:
    • Remembering best when tired (B).
    • Forgetting due to interference (C).
    • Remembering unrelated details (D).

Context-Dependent vs. State-Dependent Memory

  • Context-Dependent Memory: Refers to memory improved by being in the same location as the learning took place.
  • State-Dependent Memory: Refers to memory performance being enhanced when a person's internal state (e.g., mood, substance use) is the same at recall as it was at encoding.

Explicit Memory Defined

  • Conscious Recollection: The conscious, intentional recollection of an event or information is referred to as explicit memory.
    • Opposite of implicits:
    • Implicit Memory (a): Involuntarily retrieved knowledge.
    • Short-Term Memory (c): Temporary storage of information.
    • Somatic Memory (d): Not a standard term for memory processes.

Serial Position Effect

  • Definition: The serial position effect refers to the tendency to:
    • Remember the first and last items in a list best (B).
    • Individuals often forget the middle items (C) of the list.

Types of Amnesia

  • Anterograde Amnesia: Characterized by the inability to form new memories after the onset of impairment (B).
  • Retrograde Amnesia: Best described as the inability to recall previous memories before a brain injury (B).
