•Bahrik (1975) studied 392 participants aged 17-74 – using year books from school to recognise faces.

•Recall was tested in various ways:

-Photo recognition consisting of 50 photos

-Free recall where participants recalled as many names as they could from their graduating class

•Participants who had graduated within 15 years = 90% accurate in photo recognition.

•Participants who had graduated 48 years ago = 70% for photo recognition.

•These findings suggest that information in the LTM can last a very long time.
