retaining information

recalling information
Baddeleys (1966) aim
To investigate whether there is a difference encoding STM and LTM
Baddeley’s (1966) participants
72 participants, 15-20 in each group
Baddeleys (1966) procedure
Participants were split into 4 groups: similiar & dissimilar semantic and similar & dissimilar acoustic. And were asked to recall the words after reading them on a list.
Baddeley’s (1966) findings
accoustic encoded better than semantic encoding, however semantic encoding was remembered for longer. Similiar was recalled better than dissimilar.
Baddeley’s (1966) conclusion
acoustic encoding is STM and semantic is LTM.
Tulvings theory
Tulving proposed that there were 3 types of LTM: semantic, procedural and episodic
Procedural memory
memory of skills (e.g. riding a bike) - unconscious
Semantic memory
memory of general knowledge (e.g. spelling) - conscious
Episodic memory
memory of events (e.g. first day of school) - conscious
Tulvings advantages
lots of credibility
- Clive Wearing, a man who had severe amnesia, had lost episodic memory but still had semantic memory
- Baddeley’s study; supports the existance of semantic memory. And associated semantic memory with LTM storage
Tulvings disadvantages
- episodic memory and semantic memory are linked. E.g. if you remembered that your partner was unfaithful (episodic memory) you will probably trust them less (semantic memory)
MSM
linear model of memory implying that our memories are made up of three seperate stores: sensory memory, short term memory, long term memory
Sensory memory (MSM)
Always recieves information but most of it receives no attention and is decayed. Putting attention on the data causes it to be transferred to STM.
DURATION: 1/4 to 1/2 sec
CAPACITY: all sensory experience
CODING: sense specific/environmental stimuli
Short term memory (MSM)
Mainly encodes information acoustically. Maintenance rehearsal involves physically or mentally repeating information to extend 30 seconds. If maintenance rehearsal is not done, then information is decayed.
DURATION: 15-30 seconds
CAPACITY: 7+_ chunks
ENCODING: mainly auditory
Long term memory (MSM)
Encodes information mainly semantically. Information can be recalled to STM when needed. Elaborative rehearsal involves linking new information with information already stored there and is required to turn STM to LTM.
DURATION: minutes -> lifetime
CAPACITY: Unlimited
ENCODING: mainly semantically
MSM SCOUT
Supporting evidence: Baddeleys study
Too simples: memory is far more complex than the MSM proposed
-> Tulvings theory
Useful: gives us good understanding of the structure and process of STM - allows researchers to expand on this model
