What is memory?
The process of encoding, storing, and retrieving information.
What is encoding?
Forming a memory code—initial recording of information.
What is storage?
Maintaining encoded information over time.
What is retrieval?
Recovering information from memory stores.
What are the three types of memory in the Three-System Memory Model?
Sensory memory, Short-term (working) memory, Long-term memory.
How long does sensory memory last?
About 1 second.
How long does short-term memory last without rehearsal?
15–25 seconds.
What is sensory memory?
Brief preservation of information in original sensory form (sight, sound, touch).
What is iconic memory?
Visual sensory memory.
What is echoic memory?
Auditory sensory memory.
What did George Sperling’s study show?
People can briefly retain all items in sensory memory, even if only a few can be reported.
What is short-term memory (STM)?
Memory that holds meaningful info briefly (15–25 sec).
What is the STM capacity?
7 ± 2 items.
What is chunking?
Grouping items into larger, familiar units.
What is rehearsal?
Repeating information to keep it in STM or move it to LTM.
What is elaborative rehearsal?
Making connections to organize information meaningfully.
What is working memory?
Temporary memory that actively manipulates and rehearses info.
What are the components of working memory?
Visual store, Verbal store, Episodic buffer, Central executive processor.
What is long-term memory?
Permanent memory store; info may be difficult to retrieve.
What is the Serial Position Effect?
Recall is better for items at the beginning (primacy) and end (recency) of a list.
What is declarative memory?
Memory for factual information.
What is semantic memory?
General knowledge, facts, logic.
What is episodic memory?
Personal experiences and events.
What is procedural memory?
Skills and habits (e.g., riding a bike).
