Study Notes

Memory as an Information Processing System

Memory is a system for encoding, storing, and retrieving information.
It's compared to a computer, with encoding as input, storage as retention, and retrieval as output.

Encoding

Encoding is the input of information into the memory system.
Sensory information is labelled or coded by the brain.
Information is organized with similar information and connected to existing concepts.
This can be automatic (like recalling lunch) or effortful (studying for a test).

Storage

Storage is the creation of a permanent record of encoded information.
Information passes through sensory, short-term, and long-term memory.

Retrieval

Retrieval is the process of accessing stored information.
Recall, recognition, and relearning are the three main retrieval methods.

Types of Encoding

Semantic encoding: encoding of meaning of words.
Visual encoding: encoding of images.
Acoustic encoding: encoding of sounds, especially words.

Types of Long-Term Memory

Explicit memory: conscious memories
- Episodic memory: personal experiences
- Semantic memory: facts and general knowledge
Implicit memory: unconscious memories
- Procedural memory: skills and habits
- Priming: prior exposure affects current response
- Emotional conditioning: associating emotions with stimuli

Factors Affecting Memory

Decay: memories weakening over time.
Interference: old memories hindering new ones (proactive) or new ones hindering old ones (retroactive).
Suggestibility: leading questions or suggestions influencing memories.
Misinformation effect: inaccurate information altering memories.
Bias: personal beliefs and attitudes impacting memory.

Memory Errors

Transience: fade of memories over time.
Absentmindedness: lapse in attention leading to forgetting.
Blocking: inability to retrieve stored information.
Misattribution: confusing the source of a memory.
Suggestibility: external cues influencing memories.
Bias: personal beliefs skewing memory recall.
Persistence: unwanted memories being retained.
Intrusion: irrelevant thoughts or memories entering the memory.

Memory-Enhancing Strategies

Rehearsal: conscious repetition of information.
Chunking: organizing information into meaningful units.
Elaborative rehearsal: linking new information to existing knowledge.
Self-reference effect: relating information to oneself.
Distributed practice: spacing out study sessions.

Memory and the Brain

Different brain regions (amygdala, hippocampus, cerebellum, prefrontal cortex) play various roles in different types of memory.
Neurotransmitters (e.g., glutamate, acetylcholine) are involved in memory processes.

Amnesia

Amnesia: memory loss due to brain injury, disease, or psychological trauma.
Anterograde amnesia: inability to form new memories after the injury.
Retrograde amnesia: inability to recall memories prior to the injury.

Everyday Connections

Autobiographical memory: personal recollections.
Identifying retrieval cues for everyday tasks.
