Findings of Ebbinghaus
Found that we have 2 memory stores, STM and LTM
1 of 19
Define Primacy Effect
Remembering Items at the start of s list
2 of 19
Define Recency Effect
Remembering items at the end of a list
3 of 19
Strength of Ebbinghaus Study
Used CVCs (consonant-vowel-consonant) so they had no meaning
4 of 19
Limitation of Ebbinghaus Study
Used one participant, himself which might have experimenter bias, low ecological validity due to the use of lists that we rarely use in everyday life, CVCs do not relate to remembering real life words/lists
5 of 19
Capacity of STM
7 +/- 2 items (chunks of items etc)
6 of 19
Duration of STM
Up to 30 seconds
7 of 19
Encoding of STM
Mainly acoustic, though it can be Visual
8 of 19
Capacity of LTM
Unlimited
9 of 19
Duration of LTM
Lifetime
10 of 19
Encoding of LTM
Semantic
11 of 19
How can Capacity of STM be increased (Who found this out)
Using Chunking (Miller, 1956)
12 of 19
What Model of Memory did Atkinson and Shiffrin develop?
The Multi-Store Model of Memory (MSM)
13 of 19
What does the MSM consist of?
Sensory Memory (SM), Short-term memory (STM) and Long-term Memory (LTM)
14 of 19
Capacity, Duration and Encoding for SM?
Capacity is very small, Duration is up to 2 seconds and Encoding is via stimuli, which is modality specific
15 of 19
How is information passed from SM to STM?
By paying attention to it
16 of 19
How is information passed from STM to LTM?
Through Elaborative Rehearsal
17 of 19
Define elaborative rehearsal
Information that is processed in the STM using its meaning is passed to the LTM
18 of 19
Define Maintenance Rehearsal
Repeating information over and over again to yourself in your head to avoid decay
