It appears that couples help each other remember outstanding tasks (“to-dos”) by issuing reminders. Professor Malia Mason and co-authors examine if women and men differ in the frequency with which they offer this form of mnemonic assistance. Results converge on the possibility that men, relative to women, are less inclined to be concerned with keeping track of their partners’ outstanding needs, perhaps because doing so is a behavior that is less strongly prescribed for men than for women.
