Memory (2022) Flashcards
describe LTM
LTM consists of 3 types: episodic, semantic, procedural
split into declarative (episodic and semantic) and non declarative (procedural)
episodic memory
memory of events
semantic memory
memory of what things mean
procedural memory
memory of how to do things
declarative
episodic and semantic memory
non declarative
procedural memory
give 3 evaluation points of LTM
STRENGTH - LTM has specific locations in the brain
STRENGTH - supported by amnesiacs
WEAKNESS - too simple
elaborate strength of LTM (LTM has specific locations in the brain)
LTM has specific locations in the brain
Brain scans show that different areas have different functions e:g motor area shows procedural memory
elaborate weakness of LTM (too simple)
LTM is too simple
Distinctive types of LTM are difficult to separate so this may be a oversimplification
elaborate strength of LTM (supported by amnesiacs)
Supported by amnesiacs
Clive Wearing lost most of his semantic memory but retained his procedural memory
This shows different types of LTM are stored in different places
serial position effect
The tendency to remember words at the beginning and end of a list more than the middle
‘Serial position curve’ describes the recall if plotted on a graph
primacy effect
The tendency to remember words at the beginning of a list more as they have been rehearsed (LTM)
recency effect
The tendency to remember words at the end of a list more as they have been heard recently (STM)
aim of Murdock’s serial position curve study
To see if recall was affected by position of words in a list
method of Murdock’s serial position curve study
16 participants listened to 20 word lists of varying length (10-40w) and were asked to recall after each list. They were given 90 seconds to recall.
results of Murdock’s serial position curve study
Recall was related to position in the list
Higher recall for words at the beginning (primacy)
Higher recall for words at the end of list (recency)
conclusion of Murdock’s serial position curve study
Shows the serial position effect and supports MSM
