Just 10 minutes of talking with another person may prove helpful in improving an individuals memory and intellect, according to researchers at the University of Michigan.
"In our study, socializing was just as effective as more traditional kinds of mental exercise in boosting memory and intellectual performance," said Oscar Ybarra, a psychologist at the U-M Institute for Social Research (ISR) and a lead author of the study with ISR psychologist Eugene Burnstein and psychologist Piotr Winkielman from the University of California, San Diego.
During the study, funded in part by a grant from the National Science Foundation, the researcher examined ISR survey data to see whether there was a relationship between mental functioning and specific measures of social interaction.
The survey data included information on a national, stratified area probability sample of 3,610 people between the ages of 24 and 96. Their mental functions were assessed through the mini-mental exam, a widely used test that measures knowledge of personal information and current events.
Participants' level of social interactions was assessed by asking how often each week they talked on the phone with friends, neighbours and relatives, and how often they got together.
The researchers also looked at the connection between frequency of social contact and level of mental function on the mini-mental exam.
The study showed that the higher the level of participants' social interaction, the better their cognitive functioning. The relationship was reliable for all age groups, from the youngest through the oldest.
