Sensory Store
Limited duration, must attend to info or it's lost
2 of 14
STM
Capacity - Miller 7+/-2. Duration - Peterson and Peterson 18 seconds. Encouding - Acoustic Baddeley acoustic similar words are difficult
3 of 14
LTM
Capacity - Unlimited. Duration - Potentially a lifetime Bahricks. Encoding - Baddeley semantic words are confusing
4 of 14
Rehearsal
Maintenance Rehearsal (Maintained) . Transfer info by Elaborative Rehearsal.
5 of 14
Primacy and Recency Effect
When 20 words read out first ones are remembered due to LTM (as rehearsed) while last ones due to STM as just heared

Clive Wearing
Shows Separate stores, Shows LTM not unitary

Baddeley Word-length
Reading speed/5words/one-syllabic or pollysylabic/immediately wright down, more shorts words, could recall just as many as articulate in 2 seconds, perhaps only due to short words being better to remember as more familiar, language dif. explained
8 of 14
Peterson and Peterson
Duration of STM, trigrams, less than 10% recall after 18 seconds,but Trigrams are artificial therefore not really valid, also other trigram could not fully decay and affect new answers
9 of 14
Baddeley Encoding in STM
Acoustically similar/dissimilar, Semantically similar/dissimilar, Worse recall of acoustically similar, therefore stored as acoustically similar words
10 of 14
Bahrick
Duration of LTM, photos and graduates, 20% of recall and 60% recognition group after 50 years, more valid as meaningful stimuli, but not known if decay of info after 50 due to Duration og LTM or natural decay of memory with age
11 of 14
Baddeley Encoding LTM
Semantically similar words difficult to recall after 20 minutes therefore encoded semantically
12 of 14
Strengths
Distinguish between STM/LTM case study evidence, primacy and recency effect can be explained, lab based experiment replicable-reliable, case studies give in-depth knowledge
13 of 14
Weaknesses
Too simplistic (again Clive), needed access to LTM to process STM therefroe not linear, can transfer with other methods rather than rehearsal, lab based experiment lack realism and demand of characteristics, case studies can't be generalised
