Memory-Peter and Peterson

Question 1

Peter and Peterson 1959

Answer 1

Aim-to see if rehearsal was necessary to hold information in the short term store

Method- participants were given sets of three letters to remember (such as a GYK, MTW) but were immediately asked to count backwards in threes out loud for different lengths of time. This was done to prevent rehearsal participants were then asked to recall the letters in the correct order

Results- the results of the study showed that participants had forgotten virtually all of the information after 18 seconds

Conclusion- it was concluded that we cannot hold information in the short-term store unless we can rehearse it.
