Memory Unit Flashcards
Encoding definition
Process that moves memories from one type to the next
Memories begin with _______.
An external event
Sensory memory
- visual memories(iconic) last less than 1/2 sec
- auditory memories(echoic) last 3-4 sec
Short term memory
- aka working memory
- memories last as long as rehearsed(about 20 seconds w/o)
- most people hold 7 items +/- 2 (theory by George miller)
Long-Term Memory
- memories last minutes, hours, days, weeks, decades
- capacity is virtually limitless
Flashbulb memory
Vivid memories of an event, sometimes on a national scale.
Eidetic memory
Photographic memory
List of encoding tips
Serial position effect, over learning, rehearsal, mnemonic devices, chunking, self reference effect, effortful vs. automatic processing, semantic encoding, spacing effect, encode imagery
Serial position effect
First part of list= primacy effect
Last part= recency effect
Mnemonic devices
(Tricks)
- acronyms
- pegword
- method of loci
Semantic encoding
Understanding the meaning of things and seeing info in a logical way
Spacing effect
Aka distributed vs. massed rehearsal
Long-term potentiation
More you practice info, the stronger neuron connections become
Implicit vs. explicit memory
Implicit–skills
Explicit—facts, experiences
Structures in the brain
Long term memory–hippocampus
Short term memory–prefrontal cortex
Skill memory–cerebellum
