“Imagine that your doctor has prescribed you these medications,” the researchers told the older adults, aged 55 to 74, who were participating in an experiment at several Chicago health centers.
“Please show me when you would take these medicines over the course of one day.” After reading the instructions on seven pill bottles, the participants were asked to distribute them in a medication box with 24 slots, one for each hour of the day.
