STM & duration study and findings?
|
Peterson& Peterson
consonant trigram experiment participants were able to recall 80% of trigrams after 3 second interval. after 18 seconds, fewer than 10% of the trigrams were recalled correctly.. therefore STM is 3-18 seconds and is limited |
|
LTM & duration study and findings?
|
Bahrick.
asked people to put names to faces from there high school year book, 48 years on people were about 70% accurate in remembering. therefore LTM is unlimited |
|
STM & capacity study and findings?
|
George Miller.
Miller's Magic number 7+/-2 we have a range of 5-9 items/digits in our STM capacity. therefore limited. chunking- grouping digits/letters-improve recall in STM & helps us process info into our LTM. |
|
LTM & capacity?
|
unlimited

STM & encoding study and findings?
|
Conrad.
STM- mainly acoustically & visually. he found that acoustically similar letters/words such as B G C T V D are difficult to process in STM. |
|
LTM & encoding study and findings?
|
Baddley.
Concluded that to process memory in the LTM is has to be- semantically dissimilar coding Words that are acoustically different such as:PEN,CAT,WINDOW CAN be processed in the LTM. however Words that are acoustically similar such as: BIG WIDE LARGE do NOT process in the LTM or STM. so... Acoustically dissimilar words can be processed in the STM |

differences between stm & ltm study?
|
Research for differences between STM & LTM
Conducted by: Glazner & Cunitz Date: 1966 Experiment type: lab Experiment design: independent groups Controlled group: Recall words from list Experimental group: Distracter task then recall words Findings: Primary effect: Recall words from the start of the list as in LTM Recency effect: Recall words from end of the list as in STM |
