Study Notes

Memory

Psychology defines memory as the mind's ability to encode, store, and retrieve information.
Memories are a record of past experiences that guide future actions.
Memory is simply sensory input received from the environment.
Cognition is the processing of environmental information gathered through our senses.
Memory is the ability to encode, store, retain, and recall information and past experiences in the brain.

Where are memories stored?

The hippocampus, located in the temporal lobe, is the brain region where episodic memories are formed and indexed.

Parts of the brain involved in memory

Hippocampus: Forms and indexes episodic memories for later access.
Neocortex: Controls higher functions including sensory perception, motor commands, spatial reasoning, and language.
Amygdala: Major processing center for emotions.
Basal Ganglia: Primarily involved in motor control, also responsible for motor learning, executive functions, and behavior, and emotions.
Cerebellum: Coordinates voluntary movement, balance, and posture.
Pre-frontal Cortex: Part of the neocortex at the front of the brain; involves decision making, reasoning, personality, social appropriateness, and complex cognitive processes.

How are memories stored?

Memories are made of different neurons (nerve cells) that encode memories and control thoughts and perceptions.
Brain cells called neurons activate and form connections, creating neural patterns that represent memories.

Structures of Human Memory

Sensory memory: Acts as a buffer for incoming sensory information, retaining it briefly.
- Iconic memory: Stores visual information for 0.5 to 3 seconds.
- Echoic memory: Stores auditory information for 3 to 4 seconds.
- Haptic/Tactile memory: Stores touch-related information for 1 to 2 seconds.
Short-term memory (STM): Temporary storage system that processes incoming sensory memory.
- Lasts approximately 20 to 30 seconds.
- Used for storing information that is only needed fleetingly.
- Capacity is limited but access is rapid.
- Decays rapidly with a limited capacity of 5 to 9 chunks of information.
  - A chunk is a unit of information, which can be a single item or group of items.
  - Chunking can increase short-term memory capacity.

Mnemonic Devices

Memory aids to assist in the retention and retrieval of information.
Visual mnemonic devices: Rely on imagery.
- More whimsical and creative devices are more effective.
Acrostics/Acronyms:
- Acrostic: Uses the first letter of each line to spell out a word.
- Acronym: Shortens phrases using initials.
Rhyming mnemonics: Put information into poetry form.

Long-Term Memory (LTM)

Vast store of knowledge and records of prior events.
Duration ranges from weeks, months, years, or decades.
Unlimited capacity, slow access time, and forgetting occurs slower or not at all.
Two types of long-term memory:
- Explicit memory (Declarative Memory): Conscious recall of information like facts, events, and experiences.
  - Episodic memory: Memories of events and experiences.
  - Semantic memory: Structured record of facts, concepts, and skills derived from episodic memory.
- Implicit memory (Procedural memory): Unconscious recall of skills, habits, and conditioned responses.

Nature of Memory

Memory has essential characteristics:
- Input (Encoding): Process of creating or taking in new information to create a new memory.
- Storage: Process of holding or storing information for retrieval.
- Output (Retrieval): Process of accessing stored memory.

Processes of Human Memory

Memory is a complex process involving learning, retention, recall, and recognition. Memorization has four distinct processes:
- Encoding/Registration: Translates sensory information into a coded form for easy storage and reproduction.
- Information is transformed into engrams and codes.
- Consolidation: Strengthens the memory trace by transforming short-term memories into more stable long-term memories.
- Storage/Retention: Storing memories in various brain regions based on type.
  - Involves long-lasting changes in synaptic connections, forming what's known as a neural network.
- Retrieval: Process of accessing stored memories when needed.
  - The brain reactivates the memory’s neural pattern formed during encoding and consolidation during storage.

Models of Memory

Atkinson-Shiffrin Model of Memory: Developed by Richard Atkinson and Richard Shiffrin (1968). Memory must pass through three stages:
- Sensory memory
- Short-term memory
- Long-term memory

Why Do We Forget? Five Theories of Forgetting

Decay Theory: Memory degrades over time if not actively used.
Interference Theory: One memory competes or interferes with another.
- Retroactive interference: New information overlaps old information.
- Proactive interference: Old information overlaps new information.
Motivated Forgetting: People actively or subconsciously forget unpleasant memories, possibly a coping mechanism.
Encoding Failure: Information was never properly inserted or encoded into long-term memory.
Retrieval Failure: Memory exists but the necessary triggers or cues to recall it are missing.
- The "tip-of-the-tongue" phenomenon.

Human Memory in HCI

Human memory is a psychological process enabling users to encode, store, and retrieve information when interacting with computer systems and digital interfaces.
Understanding how memory works helps designers create user-friendly (usable) interfaces that align with user cognitive capabilities.

Theories of Memory

Memory Trace Theory: Everything we encounter or experience is recorded in the form of memory traces.

Theories of General Memory Function

Most psychologists agree that memory involves three distinct processes:
- Encoding
- Storage
- Retrieval

Information Processing Theory

Developed by Richard Atkinson and Richard Shiffrin.
Memory begins with sensory input from the environment, which is held very briefly in the sensory register.
Information recognized in the sensory register might then be passed to short-term memory (20 to 30 seconds).
Some of the information transferred to short term memory is processed by being rehearsed.
