Q

What has Endel Tulving (1985) stated?

A
  • realised the MSM version of the LTM was too simple.
  • proposed idea that LTM had 3 stores which contained different types of information.
  • includes episodic, semantic and procedural memory.

Q

What is episodic memory?

A
  • personal events and memories of when the event occurred, people, objects, places and behaviours involved.
  • need to make a conscious effort to retrieve such memories and express these in words.
  • autobiographical
    ↳ memories are about you and your experiences.
  • strength of memory can be affected by emotions felt at the time
    ↳ strongest recall of memory can be when you felt really happy or sad.

Q

What is semantic memory?

A
  • facts, what words mean, etc.
  • not always time stamped
    ↳ don’t always recall when we first remembered such facts.
  • explicit memory.

Q

What is procedural memory?

A
  • can recall these memories without a great deal of conscious effort such as driving a car (implicit).
  • sort of skills we may find hard to explain to someone else.

Q

What is the evaluation of LTM - clinical evidence?

A

POINT - one strength is the supportive clinical evidence.
EVIDENCE - supported by memory case studies such as Patient HM and Clive Wearing. Their episodic memory was severely impaired due to amnesia but heir semantic and procedural memories were unaffected. Patient Hm was unable to recall owning or stroking a dog but did not need an explanation on what a dog was. Both knew how to walk, speak and in the case of Clive, a professional musician, was still able to play the piano, sing and read music.
EXPLANATION - suggests LTM is not a unitary store but constitutes different types like episodic, semantic and procedural.
LINK - supports Tulving’s view that there are different memory stores in the LTM where there is a possibility for one store to be damaged and others to go unaffected.

Q

What is the evaluation of LTM - neuroimaging evidence?

A

POINT - one strength is neuroimaging evidence from brain scan studies.
EVIDENCE - Buckner and Peterson (1996) found episodic and semantic memories were both recalled from the prefrontal cortex which is divided into two, one on each side of the brain. Left prefrontal cortex was involved in recalling semantic memories and episodic memories were recalled from the right prefrontal cortex.
EXPLANATION - suggests that different areas of the brain are activated when recalling a particular type of memory.
LINK - supports Tulving’s idea of different types of stores for LTM.

17
Q

What is the evaluation of LTM - real life application?

A

POINT - one strength is that it has enabled psychologists to help people with memory problems.
EVIDENCE - Bellville et al (2006) found that episodic memories could be improved in older people who had a mild cognitive impairment where results found that trained participants performed better on a test of episodic memory compared to control group.
EXPLANATION - suggests that identifying the different types of LTM is beneficial as it allows specific treatments to be developed bettering people’s lives as they are able to recall episodes in their own life.
LINK - help improve the quality of life of people with memory disorders.

18
Q

What is the evaluation of LTM - problems with clinical evidence?

A

POINT - one weakness is the issues associated with clinical evidence.
EVIDENCE - lack of control of all sorts of different variables in clinical studies.
EXPLANATION - involves people who have had brain injuries due to unexpected accidents therefore psychologist has no control over what happened to patient before they experienced the injury. E.g. very little idea of patient’s memory before injury in case of amnesia therefore there is no knowledge on how much worser it got.
LINK - conclusions researchers have reached about memory based on clinical studies may not be internally valid.

What is the evaluation link of LTM - clinical evidence?
