models of memory
explanations to how memory works
three box/information processing model
external events are processed by sensory memory, before some of it gets encoded into short term. some more info is then encoded into long term memory.
any info that is not encoded is lost
iconic memory
split second perfect “photograph” of a scene
echoic memory
perfect brief (3–4 secs) memory for audio
selective attention
encoding what is important or what we are currently paying attention to
short term memory
memories that usually fade after 10-30 secs. has capacity of 7 items on average
clunking
grouping any number of items into 7 groups
mnemonic devices
memory aids
(ex, ROYGBIV= colors of rainbow)
long term memory
permanent memory with unlimited storage
decay
when long term memories fade over time
episodic memory
memories of specific events stores in chronological order
semantic memory
general knowledge of the world
procedural memory
memories of skills and how to perform them
explicit/declarative memories
memories that are intentionally remembered/recalled
implicit/nondeclarative memories
memories that are not intentionally remembered/recalled
levels of processing model
memories are either deeply/elaborately processed or shallowly/maintenance processed.
states that people remember things more if they spend more time and energy on it
retrieval
last step of any memory model.
gets information out of storage and into consciousness.
there are 2 kinds: recognition & recall
recognition
matching a current event/fact with one already in memory
recall
retrieving a memory when given an external cue
primary effect
predicts that items shown in the beginning are more likely to be recalled
