People Remember Mondays and FridaysA new study published in PLOS ONE explores how people’s cognitive depictions of weekdays are constructed and what effect it has on their perception of time—in particular remembering what day of the week it is.

The study aimed to shed light on a possible link between the seven-day weekly cycle and basic cognition; they accomplished this by characterizing mental representation of the weekdays.

Study participants were asked which words they associated with specific days of the week. Results indicated that Mondays and Fridays had the most mental representations. Monday was linked with negative words, such as “boring” and “tiring.” Friday was associated with positive words, such as “freedom” and “party.”

There were fewer representations for the other weekdays, which indicated to researchers that they carried less meaning and made them harder to remember.

Researchers tested participants on how quickly they could correctly state what day it was. The results showed that participants could correctly indicate when it was Monday or Friday twice as fast as they could identify a Wednesday. Furthermore, when people got the day of the week confused with another, it usually occurred in the middle of the week.

Dr. David Ellis, the study’s lead researcher, suggests that a weekday may not be remembered based on where it falls on the seven-day cycle, but where it falls in relation to the weekend.
