Statistics / Researchers / Case Studies Flashcards
What is the capacity of STM?
7 +/- 2 units.
Who conducted research into the capacity of STM?
Miller (1956).
What is the duration of STM?
18-30 seconds.
Who conducted research into the duration of STM?
Peterson and Peterson (1959).
After 3 seconds, what was the percentage of accurate recall of the trigram?

Who conducted research into STM coding?
Baddeley (1966).
Who conducted research into LTM coding?
Baddeley (1966).
Who proposed the Multi-Store Model of memory?
Atkinson and Shiffrin.
What year was the Multi-Store Model proposed?
1968.
What happened to KF?
Suffered brain damage in a motorcycle accident. His verbal STM was damaged, however, his visual STM was mostly unaffected.
Who conducted the serial position research?
Murdock (1962).
What model of memory does ‘serial position research’ support?
Multi-Store Model.
What happened to Clive Wearing?
He contracted a viral infection in his brain. He lost his episodic memory but his procedural memory was unaffected (could still play the piano but had no memories of his wedding).
Who conducted research into the sensory register?
Sperling (1960).
Which model of memory does Sperling’s research support?
Multi-Store Model.
Which case studies support/disprove the Multi-Store Model?
- KF (strength and weakness).
- Clive Wearing (weakness).
Who proposed the Working Memory Model?
Baddeley and Hitch.
What year was the Working Memory Model proposed?
1974.
What is the capacity of the visuospatial sketchpad?
3-4 items.
Which year was the Episodic Buffer added?
2000.
Which case study supports the Working Memory Model?
KF.
Who conducted the ‘dual-task’ research?
Baddeley et al (1975).
Who conducted research into musical memory?
Berz (1995).
Who proposed the different types of long-term memory?
Tulving.
What year were the different types of LTM proposed?
1985.
Which case study supports the different types of LTM?
Clive Wearing.
Who conducted research into brain scan evidence for the different types of LTM?
Tulving et al (1994).
