Study Notes

Memory is a complex cognitive process involving encoding, storage, and retrieval of information.

Types of Memory

Sensory memory: A brief storage of sensory input (iconic - visual, echoic - auditory) with a large capacity but very short duration.
Short-term memory (STM): Limited capacity (7 ± 2 chunks) and short duration memory store. Rehearsal and chunking enhance STM capacity.
Long-term memory (LTM): A relatively permanent and unlimited capacity memory store.
- Explicit (declarative) memory:
  - Episodic memory: Personal experiences and events.
  - Semantic memory: General knowledge and facts.
- Implicit (non-declarative) memory: Procedural memory (skills and habits), priming, classical conditioning.

Processes of Memory

Encoding: Transforming sensory information into a neural code that can be stored in memory (visual, acoustic, semantic). Mnemonic devices are used to aid encoding.
Storage: Maintaining encoded information in memory over time. Memory consolidation involves moving information from STM to LTM.
- Role of brain regions (hippocampus, amygdala).
Retrieval: Recalling stored information.
- Free recall, cued recall, recognition.
- Context-dependent and state-dependent retrieval.
- Retrieval cues aid retrieval.

Models of Memory

Atkinson-Shiffrin Model (Multi-Store Model): Three-stage model of memory (sensory, short-term, long-term).
Baddeley's Working Memory Model: A more complex model of STM including components like the central executive, phonological loop, and visuospatial sketchpad, and episodic buffer.
Levels of Processing Model: Deeper processing leads to better memory retention.
Tulving's Model of Memory Systems: Classifies LTM into explicit (declarative) and implicit (non-declarative) memory.

Forgetting and Memory Failures

Theories of forgetting:
- Decay theory: Memories fade over time if not used or rehearsed.
- Interference theory: New information disrupts the retrieval of old information (retroactive) or old information disrupts the retrieval of new information (proactive).
- Retrieval failure: Information is stored but cannot be retrieved due to a lack of appropriate cues.
Amnesia: Loss of memory, either retrograde (loss of past memories) or anterograde (inability to form new memories). Caused by brain injury or trauma.
Tip-of-the-tongue phenomenon: A temporary inability to retrieve information that is stored in memory.

Memory and the Brain

Role of hippocampus, amygdala, prefrontal cortex, and cerebellum in memory processes.
Neurotransmitters involved: acetylcholine, glutamate, and others.

Memory Development

Memory development changes across the lifespan, with changes in infancy and childhood, and age-related changes.
Neuroplasticity influences memory development.

False Memories and Reconstruction

Misinformation effect: Incorporating misleading information into memories.
Eyewitness testimony: Susceptibility of eyewitness accounts to inaccuracy.
Source monitoring errors: Confusing the origins of a memory.

Applied Memory

Memory techniques and strategies
Role of memory in learning and education
Memory enhancement/training
Memory in artificial intelligence.

Special Topics

Flashbulb memories: Detailed and vivid memories of emotionally significant events.
Autobiographical memory: Memory of personal experiences.
Prospective memory: Remembering to perform actions in the future.
Memory disorders (Alzheimer's, dementia): Brain diseases that damage/weaken memory processes.
