what is memory?
a single term that reflects the retention of information over time
What are the 4 kinds of memory?
- sensory memory
- short-term memory
- Long term memory
- working memory
What is sensory memory?
- each sense had it’s own system (eg. iconcic, echoic)
- the duration is short, but capacity is very large
What is short term memory?
- related to working memory,
- duration of information lasts about 20 seconds
- everything in your head right now
Who is tested sensory memory?
- George Sperling
What is the duration for sensory memory?
- 1/2 sec for visual
- 2-4 seconds for auditory
How long is the duration of short term memory?
duration of information lasts about 20 seconds
What is the golden rule for short term memory?
- 5+ or -2
What is working memory?
- holds information temporarily for analysis
- up to 30 sec without rehearsal
- limited to 5-9 items
What is the duration of working memory?
up to 30 sec without rehearsal
What is Chunking (short term memory)
way to group information in meaningful ways
What is rehearsal?
- simple; repeat information
- elaborate: make meaning of the information
what is the duration and capacity of longterm memory?
infinite
Two types of long term memory?
- explicit (declarative)
- implicit (non- declarative)
What are explicit memories?
- Explicit memories are those we consciously try to remember and recall
- storage of facts and events and is the type of memory you are aware of having and can consciously express
What are the 2 types of explicit memories?
- episodic memory
- semantic
What is episodic memory ?
- Episodic memory is information about events we have personally experienced
What is semantic memory?
- our knowledge about facts
What are non- declarative or implicit memories?
- Are not part of our consciousness.
- They are memories formed from behaviors.
What are 2 types of implicit memories ?
- procedural
- emotional conditioning
What is Procedural memory?
- information about how to do things
- where you are able to perform actions without consciously monitoring
What is Emotional Conditioning?
- Memories acquired through classical conditioning, - you get when smelling the aroma of favorite food truck while walking by.
- Associations are created implicitly between stimuli that commonly occur together
What are the three stages of memory?
- encoding
- storage
- retrieval:
What is Encoding
process of getting information into our memory
