When people use their computer or smartphone to store information, they may not be able to detect if that information has been manipulated when they retrieve it later, according to researchers from the University of Waterloo.
“In our study, individuals could rely on an external store when trying to remember some material and manipulations of that store often went undetected,” said Evan Risko, lead author of the study and a professor of psychology.
For the study, participants performed a series of memory tasks where they were required to use a file on a computer to store and later recall a list of words that the researchers presented to them. This computer file functioned as the participant’s external memory store similar to how people might store information they want to remember on a smartphone. For the first three trials, the list the participants stored on the computer was untouched. This allowed participants to develop trust in their external memory store.
