Memory Plasticity
For testing
Term | Definition |
---|---|
What were the research questions (Ericcson, Chase & Faloon, 1980) | Was the limit for memory experts only? Were skills a result of extensive practice or exceptional ability? |
kParticipants | 1 male UG student |
Task | Random digits @ 1/sec THEN recall the sequence |
Task Variability / sequence | Increased by one digit if correct or decreased by one if incorrect |
Strategy employed by participant 1 | Mnemonics, running times and significant event years or dates |
Strategy employed by participant 2 | Coded first 6 digits and held last 4-6 digits in rehearsal buffer |
Strategy employed by participant 3 | Supergroups - used segmentation (chunking) |
Historically linked research | Luria's 'S' Hunt & Loves 'V.P' |
Results | Up to 80 digits after 20 months |
Results on cognition: | Speech patterns = 3digit/sec with pauses of 2 seconds |
Conclusion 1 / findings | If a supergroup didnt work out then it could take up to 10 seconds to re-align memory |
Conculsion 2 / findings | Numbers difficult to asociate with mnemonic model performance dropped to almost beginning levels |
Conclusion 3 / findings | No transfer effect, appears to be all about the menemonics, consonants didnt work and return to again beginning performance |
