The mnemonic peg system, invented by Henry Herdson,[1] is a memory aid that works by creating mental associations between two concrete objects in a one-to-one fashion that will later be applied to to-be-remembered information.
[3] Memory grand master, Ed Cooke, reportedly has been working on the Millennium PAO system, which would create an association for all numbers 000-999.
The students that used the peg system performed significantly better than the control in both immediate and delayed tests.
The individual can develop a mnemonic peg system in order to remember this association by thinking of a duck with a pot on its head.
The peg system works, so long as the information trying to be remembered is specific, able to be visualized, and tied to a unique retrieval cue.
