07b_Memory and Forgetting Flashcards
Memory:
Three Processes
Encoding
Storage
Retrieval
Information processing model (Multi-Store):
Three components
Sensory memory
Short-term memory
Long-term memory
Sensory memory (aka Sensory register)
Brief storage of sensory stimuli (a few seconds)
Echoic Store
Iconic Store
Echoic Store
Sensory memory of auditory information
Iconic Store
Sensory memory of visual information
Short-term memory:
Overview
Limited amount of information
Without rehearsal, info begins to fade within 30sec
Short-term memory:
Encoding
Primarily acoustic
May also be semantic, visual, kinesthetic
Short-term memory:
Primary Memory
Passive memory storage
5-9 distinct units
Larger amounts held by chunking information
Short-term memory:
Working memory
Manipulation and processing of information
Long-term memory:
Converting information from STM
Elaborative rehearsal
Maintenance rehearsal
Elaborative rehearsal
Relating new information to existing information
Maintenance rehearsal
Simply repeating information with little or no processing
Long-term memory:
Encoding
Mostly semantic
May be encoded visually or acoustically
Long-term memory:
Capacity
Unlimited
Permanent
Long-term memory:
Two timeframes
Recent (secondary) memory
Remote memory
Serial Position Effect
Supports existence of separate short-and long-term stores
Primacy effect
Recency effect
Levels-of-Processing Model:
Overview
Alternative to information processing model
Differences due to depth of processing rather than separate memory stores
Levels-of-Processing Model:
Three Levels of Processing
Structural
Phonemic
Semantic
Which processing level is deepest and produces greatest amount of recall?
Semantic Processing
Long-Term Memory:
Procedural memory
Learning “How”
Cognitive skills
Motor skills and habits
Long-Term Memory:
Declarative memory
Learning “What”
Acquisition of facts and other information
Semantic and Episodic memory
Declarative Memory:
Semantic Memory
General knowledge
Independent of any context
e.g, facts, rules, and concepts
Declarative Memory:
Episodic Memory
Autobiographical memory / personal experience
Flashbulb memories
Type of memory most affected by normal aging
Episodic Memory
