Memory- STM and LTM 0.0 / 5 ? PsychologyMemoryA2/A-levelAQA Created by: pollywantsabCreated on: 21-02-18 10:37 What was Miller's research based on? Counting dots, musical notes and words 1 of 20 Miller's research on the capacity of the STM found that? That it was 7 +/- 2. 2 of 20 Who said that Capacity of STM is likely to be even smaller than this? Cowan (2001) reviewed STM research and said it is likely to be only 4 after seeing Vogel's research 3 of 20 What did Simon (1974) say? Simon says that its the size of the chunk that affects capacity and that more smaller chunks can be recalled 4 of 20 What's a limitation of Miller's theory? Individual differences 5 of 20 What was Peterson and Person's research based on? Recollection of consonant syllable after counting back from a three digit number. 6 of 20 What did Peterson and Peterson find as the duration of the STM? Recall accuracy: 3 Seconds -90%, 9 seconds- 20%, 18 seconds- 2% 7 of 20 What is a limitation of Peterson and Peterson's research Lacking in ecological validity- Lab study 8 of 20 What is a limitation of the STM duration research? Lacks internal validity as information may have been displaced not lost 9 of 20 What's the capacity of the LTM? Potentially limitless 10 of 20 What was Bahrick's research based on? Recalling names of high school classmates, using yearbook photos as a prompt 11 of 20 What did Bahrick et Al (1975) find as the duration of the LTM? Recall with photo prompt: 15 years- 90%, 48 years- 70% 12 of 20 What is a limitation of Bahrick's research? May lack accuracy as people may have kept in contact with high school classmates. 13 of 20 What was Baddeley's research into coding based on? Recollection of acoustically similar and semantically similar words 14 of 20 What did Baddeley find out about STM? Coded acoustically 15 of 20 What did Baddeley find out about LTM? Coded semantically 16 of 20 What is a limitation of Baddeley's research into LTM? Lack's internal validity, only tested 20 minutes later, not enough time for it to be LTM 17 of 20 Why might STM not be coded entirely acoustically? Brandimonte et al (1992) found out that coding may also be visual 18 of 20 STM- Capacity, Duration and Coding? Capacity- 7 +/- 2, Duration- 3-9 seconds, Coding- mainly acoustic 19 of 20 LTM- Capacity, Duration and Coding? Capacity- Potentially unlimited, Duration- potentially a life time, Coding- Semantic 20 of 20
