Peterson and Peterson (1959)
Outline Peterson and Peterson’s 1959 study methodology
- They showed participants a trigram (3 letter nonsense word)
- Participants had to recall the trigram after counting backwards in 3s from 300. The length of time they had to count for varied from 3 seconds to 18 seconds to see how long it was until participants forgot the word

The longer the interval delay, the less trigrams were recalled (80% after 3 seconds, 10% after 18 seconds)
What is the duration of the long term memory?
Lifetime
