Flashcards
Coding, Capacity and Duration of memory
Cards in this deck (15)
- 1Baddeley researched which part of memory?Coding
- 2What did Baddeley find from his research?Information is coded semantically in long term memory
Information is coded acoustically in short term memory - 3What is the main limitation of Baddeleys research?Artificial stimuli - the word list has no personal meaning to participants
Limited application - 4What did Jacobs research into?Capacity of memory, specifically digit span
- 5What did he do and what did he find?He measured digit span (how many numbers/letters pp could remember)
Findings: 9.3 digits, 7.3 letters - 6What did Miller research into?Capacity of memory
- 7What did he find?We remember 7+-2 chunks on average
- 8One limitation of Jacobs research?Lacks validity - study was conducted a long time ago not as much control
Confounding variables - 9One Limitation of Millers research?Capacity may be over estimated
Cowan estimated only about 4 chunks - 10Who researched duration in short term memory?Peterson and Peterson
- 11What did they find?That STM lasted up to 18 seconds without rehearsal
- 12Who researched duration in long term memory?Bahrick et al (Yearbook)
- 13What did he find in his research?Recognition of faces was 90% after 15 years, recall of names was 60%
Recognition dropped to 70% after 48 years - 14One limitation of Peterson and Peterson?They used meaningless stimuli - remembering consonant syllables doesnt have any significance to real life
Lacks external validity - 15One strength of Bahricks study?Higher external validity
Real-life meaningful memories studied
Shephard - greater recall with meaningful memories rather than other controlled studies
