Psychology - Memory - Long Term Memory Short Answer Flashcards
Longterm Memory
Divided into two types
Explicit
Implicit
Explicit Memory
consciously try to remember and recall
i. e. when studying for an exam
- episodic memory
- semantic memory
Implicit Memory
memories that are not part of our consciousness
-formed from behaviours
-procedural memory
(can also be called non-declarative memory)
Procedural Memory
stores information about how we do things
i. e. learning how to swimming
- no conscious recall
- type of implicit memory
Glanzer and Cunitz
Study and Aims
1966
the serial position effect
-to investigate whether STM and LTM are different memory stores
Glanzer and Cunitz
Procedure
pp’s given a list of common words to memorise
then were asked to recall as many as possible
Glanzer and Cunitz
Results
pp’s remembered more words on average from the beginning (primacy effect) and the end (regency effect) rather than in the middle
SERIAL POSITION EFFECT
Glanzer and Cunitz
Conclusion
pp’s remembered more words from the beginning of the list because they had been transferred by rehearsal to the LTM
-Words at the end of the list were still in the STM
Miller STM Limited Capacity
words in the middle were forgotten because of the limited capacity of the STM

Glanzer and Cunitz
Evaluation
Strengths
- reliable, easy to replicate
- practical applications for improving memory of important information
Limitations
-lacks ecological validity, not how we use memory in everyday life
Milner et al HM
1966
Epilepsy patient
-surgery destroyed his hippocampus leaving him with severe amnesia
-he was unable to make new memories
HM patient Aim and Method
Aim to investigate anterograde amnesia
Method a case study using numerous psychometric tests, experiments and observations
HM patient Results
HM had the ability to learn new motor skills so his procedural memory was intact.
- could not make new episodic and semantic memories
- had working memory as he was able to hold conversations
- STM AND LTM no longer connected
HM patient Conclusion
- causes of brain damage such as HM supports the distinction between LTM and STM
- damage to the hippocampi destroys LTM, memory only lasts as long as their STM
HM patient Evaluation
strengths
-in depth and detailed
limitations
-cannot generalise from a case study
