Memory Flashcards
How does memory work?
Triggers and clues aid recall of memories that are rehearsed
Primacy effect
First information given
Recency effect
Recent information given
Information processing
Information is taken in by the senses and responded to
Computer analogy
Human mind operates Iike a computer- handles input, processes and outputs in the form of behavior
What is the memory?
The mental process used to encode, store and retrieve information
How important is the memory?
Allows us to recall events, skills and knowledge
Example of developmental changes in memory
Alzheimer’s effects people over 65
Who came up with the multi store model and when?
Atkinson and Shiffrin’s - 1969 and 1971
What is the order of the msm?
Sensory memory-short term memory-long term memory
What information is encoded in the sensory memory?
Sight, touch, taste, hear, smell
How long is information held in the sensory memory and why is this?
1-2 seconds due to limited capacity
How is information from the sensory memory moved into the STM?
Attention
How long are memories held in the STM and how many items are held?
15-30 seconds- 7 +/- 2 items
What happens to info that is not rehearsed in the STM?
Displacement
How is info moved from the STM to my LTM?
Rehearsal in the rehearsal loop
Capacity and time of the LTM?
Infinite
How is information lost from the LTM?
Trace decay- dissipates
Evaluation of the msm
- distinction between the STM and LTM
-supports serial position effect with the rehearsal loop
-case of HM as he was unable to transfer info over to LTM
-more than one LTM store
-people do not need to rehearse
Serial position effect?
Position of information and its chance of recall
Intermediate effect
Low recall of information given in the middle of a list
How does the STM encode?
Acoustically
How does the LTM encode?
Semantically (meaning)
Who created the working memory model and when?
Baddeley and Hitch (1974)
What did baddeley and hitch believe?
The stm store in the msm was too simplistic- they believed there was different processes that manipulate info
What are the different parts of the wmm?
Central executive, Visuo-spatial sketch pad, phonological loop (articulately control system and phonological store), episodic buffer, LTM
Where does data come into?
Central executive
What is the role of the articulately control system?
Rehearses words as the inner voice
role of the phonological store?
Stores what you hear
Role of central executive?
Organization of information
Role of phonological loop?
Auditory information
Role of visuo-spatial sketch pad?
Deals with visual information and records placement
Role of episodic buffer?
Pulls info from LTM
What are the 3 parts of the LTM?
Language, episodic LTM and visual semantics
Who was KC?
Amnesiac who showed how we make memories meaning and personal. After being in a motorcycle accident and loosing hippocampus- Tulving discovered he could remember semantic facts due to his parahippocampus
What did Tulving do and when?
In 1972 made the distinction between semantic and episodic LTM
Semantic memory
Stores meaning, concepts, facts
Episodic memory
Stores experiences and events with emotion
