Bahrick - LTM Duration experiment:

Studied 392 participants from Ohio, aged between 17 and 74
High school yearbooks were obtained from the participants or directly from schools
Recall was tested in various ways including; a photo recognition test consisting of 50 photos, some from the school yearbooks, and a free recall test where participants recalled the names of their graduation class
Participants who were tested within 15 years of graduation were about 90% accurate in photo recognition and 60% accurate in free recall
Participants who were tested within 48 years of graduation were about 70% accurate in photo recognition and 30% accurate in free recall
This shows LTM can last a very long time
High external validity - uses real life meaningful memories
Confounding variables were not controlled - participants may have looked at book and rehearsed memory over the years
