    Study Notes

    Foundations of Cognition I

    • Last Class: Covered short-term memory and working memory.
    • Today: Focus is on long-term memory.

    Long-Term Memory

    • Interfaces with working memory, allowing for manipulation of information from long-term storage.
    • Declarative LTM: Stores facts and experiences.
    • Procedural LTM: Stores skills and actions.

    Early Model: Atkinson & Shiffrin (1968)

    • Long-term Memory (LTM): Unlimited capacity and duration, with memories lasting from minutes to a lifetime.
    • Unlimited Storage: Unlike short-term memory, LTM doesn't rapidly forget information.
    • Unlimited Duration: Memories can be stored for extended periods, even an entire lifetime.
    • Sensory Registers: (Visual, auditory, haptic) receive environmental input.
    • Short-term Memory (STM): Temporary working memory.
    • Control Processes: (Rehearsal, coding, decisions, retrieval) affect how information is processed.

    Control Processes

    • Rehearsal: Repeating verbal information to maintain it in short-term memory, using the phonological loop; a form of rote learning (memorization).
    • Coding: Semantic elaboration of information to help it be remembered better, placing it in context of other information. This makes the information easier to remember.
    • Imaging: Creating visual images to make material easier to remember. This uses the visuospatial sketchpad while encoding.
    • Mnemonics: Memory aids linking complex information to simpler, easier-to-remember information, like a system for classifying star temperatures, which can be remembered with a phrase ("Oh Boy, Another F's Gonna Kill Me").

    Rundus (1971): Serial Position Effect

    • Words at the beginning and end of a list are recalled better than those in the middle due to primacy and recency effects.
    • Primacy Effect: Better recall of words at the beginning of a list because they've likely been rehearsed more.
    • Recency Effect: Better recall of words at the end of a list because they are still in short-term memory.

    Stages of Long-Term Memory

    • Acquisition: Initial storage of information in long-term memory
    • Retention: Maintaining information, requiring initial encoding and consolidation
    • Retrieval: Recalling information. Consolidation is the process of stabilizing memory traces after initial acquisition. It occurs over time, moving memories to long-term storage.

    Sleep & Memory

    • Memories are strengthened during sleep.
    • Targeted memory reactivation (cues presented during sleep) can improve memory.
    • Smith & Weeden (1990): Clock Experiment: Cued group (stimulated during sleep) showed significantly better task improvement up to a week later.
    • Shows that targeted memory reactivation during sleep aids memory consolidation.

    Consolidation

    • Hebbian Learning: Synaptic strengthening due to consistent pairing of neuron activities.("Neurons that fire together, wire together" – Hebb).
    • Long-Term Potentiation (LTP): A lasting increase in synaptic strength after repeated stimulation, strengthening connections between neurons that repeatedly fire together. This is thought to be a biological mechanism supporting long-term memory formation.
    • Bliss & Lømo (1973): Discovered LTP, a vital mechanism for LTM.
    • NMDA Receptors: Channels on neurons; blocked by magnesium ions and need both action potential and glutamate to open, strengthening the connection when two neurons fire together.

    Memory Encodings

    • Engram (memory trace): Imprinted physical information. A theoretical physical representation of memories in the brain. LTP is a potential process for engrams.

    Types of Long-Term Memory

    • Declarative (Explicit) Memory: Requires conscious recall. Includes episodic and semantic memories. - Episodic Memories: Event-based memories, including context (where, when). - Semantic Memories: General knowledge.
    • Non-declarative (Implicit) Memory: Doesn't require conscious recall. Includes procedural memories, classical conditioning, and other types of associative and non-associative learning

    Episodic Memory

    • Stores specific events and their context (time, location).
    • Place Cells: Neurons in the hippocampus that activate when an individual is in a specific location. Used in spatial mapping, enabling the brain to map an environment.

    Semantic Memory

    • Stores general knowledge, not tied to a specific event (e.g., facts, concepts, categorical knowledge). Storage is distributed throughout association areas in the brain.

    Patient H.M. (Henry Molaison)

    • Had surgery removing parts of temporal lobe, including connections to the hippocampus to control seizures.
    • Experienced severe anterograde amnesia (inability to form new memories) but his short-term memory and intelligence remained intact.
    • Highlights the importance of hippocampus to memory function.
    • Temporally-Graded Amnesia: recent events forgotten more than older memories.

    Standard Model of Declarative Memory

    • Hippocampus: Initially encodes information, including context like time and place.
    • Cortex: Over time, memories transfer from the hippocampus to the cortex; fully consolidated memories are stored in the cortex.

    Multiple Trace Theory

    • New trace formed in the brain with every retrieval attempt.
    • Hippocampus is always (even for old memories) involved.
    • Memories, on recall, are altered, through a process called reconsolidation.

    Procedural Memories

    • Memory of actions and skills (e.g., tying your shoes).
    • Associated with the striatum and cerebellum (part of the basal ganglia).
    • Damage to these areas causes a loss of procedural abilities.

    Associative Memory

    • Information Retrieval based on related cues. Ex: Classical Conditioning (learning a fear).

    Non-Associative Memory

    • Learning without associations. Covers Habituation (decrease in response after repeated stimulus) and Sensitization (increase in response after a strong stimulus)
    • Usually involves a reflex-arc type local mechanism

    Eric Kandel: Gill Withdrawal Reflex

    • Demonstrated that LTP underlies the formation of simple memories, like reflexes (e.g., aplysia's gill withdrawal) from non-associative learning like habituation.
