Remembering why: Can people consistently recall reasons for their behaviour? (Study)

“Nearly six hundred undergrads answered open-ended questions about why they’d purchased, downloaded or copied their most recently acquired album (the vast majority had acquired one within the last two weeks), and then they provided the same information again six months to a year later. The participants’ answers fell into five main categories: because they liked the artist, liked the music, liked a specific song or songs, someone had recommended the album, or they needed the album for a specific purpose.

The key finding was that only one in five participants gave a consistent reason or reasons at both time points. […]

A subset of 82 of the participants also gave their reasons at a third time point, approximately six months to a year after the second time of questioning. Although still evident, changes in memory between the second and third time points were far reduced compared with between the first and second time points. This is important for real-life legal situations because consistency of answers across later interviews could be interpreted as a sign of memory reliability. ‘It appears critical to have an accurate and complete record of the very first interview given by a witness,’ the researchers said.”
