Q

What else may semantic memory relate to?

-functions of an object
-what behaviour is appropriate to use in a certain situation
-abstract concepts e.g mathematics and language

Q

How do episodic memories become SEMANTIC?

Memory loses its ASSOCIATION to a particular event and becomes GENERALISED

Q

Why are we less aware of procedural memories

A

they have become AUTOMATIC and UNAVAILABLE of conscious introspection

Q

What happens if we think too much about procedural memories

A

prevents us from carrying them out.
e.g if you think too much about riding a bike it will cause you to lose your balance

Q

Why is it important that procedural memories are AUTOMATIC

A

so we can focus our attention on other tasks whilst performing these everyday motor skills

Q

Where are procedural memories stored?

A

in the CEREBELLUM

17
Q

State one POSITIVE evaluation of LTM
(Hint: Amnesia)

A

Evidence for the distinction between EPISODIC/SEMANTIC and PROCEDURAL memory has come from research=patients with amnesia

Patients with amnesia= unable to store NEW episodic or semantic memories

HOWEVER, procedural memory=largely unaffected

18
Q

State a POSITIVE evaluation of LTM
(Hint: brain scans+ recall)

A

Scientific evidence captured from brain scans SUPPORTS idea of DIFFERENT types of LTM.

E.g when asking patients to RECALL different types of information, different areas of the brain were shown to be active on an fMRI.

Episodic=hippocampus
Semantic= temporal lobe
Procedural= cerebellum

19
Q

State a POSITIVE evaluation of LTM
(Hint: Clive wearing)

A

Case studies of brain damaged patients offer support for the different types of LTM.
e.g. Clive Wearing is a man who suffered from a viral infection which damaged his hippocampus

He has NO episodic memory and cannot form NEW semantic memories.

HOWEVER, his procedural memory is still intact (e.g. he can still play the piano)

20
Q

State a NEGATIVE evaluation of LTM
(Hint: individual case studies)

A

Research into the different types of LTM have typically been conducted on INDIVIDUAL PATIENTS (e.g clive wearing and HM)

Although case studies are highly detailed and provide A LOT of information, they are ISOLATED CASES of one individual

It would be inappropriate to assume that everyone’s LTM is formed in the same way-> findings cannot be generalised to WIDER population
