How was duration for STM tested?
Using Nonsense Trigrams
1 of 14
Who conducted research for STM duration?
Peterson and Peterson
2 of 14
Findings of duration of STM research?
80% of trigrams were recalled at 3 second intervals. This decreased down to 10% at 18 secs.
3 of 14
Duration of STM?
18 seconds
4 of 14
Reliability high or low in duration for STM duration research?
High as the settings were controlled
5 of 14
What was validity and generalisability like in study for duration in STM?
Ecological validity was low as it was a lab experiment. Generalisability was low as procedure was not everyday behaviour.
6 of 14
Who conducted research into capacity of STM?
Jacobs
7 of 14
What was the procedure for research into STM capacity?
Digit Span Technique (Read lists of different length word/letters/numbers and have to recall as many as possible)
8 of 14
What were the findings of Jacobs research into STM capacity?
Recall for: numbers=9.3/ letters=7.3.
9 of 14
Was age a factor in research into capacity for STM?
Yes. Eight year olds remembered 6.6 characters, and 19 year olds remembered 8.6.
10 of 14
Millers magic number?
7+-2
11 of 14
Evaluation of capacity research in STM?
High realability, low ecological validity, lacks generalisability.
12 of 14
Who conducted research into Encoding for STM?
Conrad
13 of 14
What were the findings for encoding in STM research?
STM is encoded acoustically as PPS found it harder to recall letters which were acoustically dissimilar
