Detailed explanation-1: -Peterson & Peterson used a sample of 24 psychology students, which is an issue for two reasons. Firstly, the psychology students may have encountered the multi-store model of memory previously and therefore may have demonstrated demand characteristics by changing their behaviour to assist the experimenter.

Detailed explanation-2: -Lloyd and Margaret Peterson aimed to test the hypothesis that information which is not rehearsed is lost quickly from short-term memory.

Detailed explanation-3: -Bahrick, Bahrick, and Wittinger (1975) investigated what they called very long-term memory (VLTM). Nearly 400 participants aged 17 – 74 were tested. Participants were asked to list the names they could remember of those in their graduating class in a free recall test.

Detailed explanation-4: -Peterson and Peterson aimed to investigate the duration of short-term memory and also provide evidence for the multi-store model.
