Washington: A new research has shown that learning only certain activities, such as photography, may help elderly improve their cognitive functioning.
These findings reveal that less demanding activities, such as listening to classical music or completing word puzzles, probably won't bring noticeable benefits to an aging mind.
Lead researcher Denise Park of the University of Texas at Dallas, said that it seems it is not enough just to get out and do something-it is important to get out and do something that is unfamiliar and mentally challenging, and that provides broad stimulation mentally and socially.
She asserted that when people are inside their comfort zone they may be outside of the enhancement zone.
For their study, Park and colleagues randomly assigned 221 adults, ages 60 to 90, to engage in a particular type of activity for 15 hours a week over the course of three months.
Some participants were assigned to learn a new skill - digital photography, quilting, or both - which required active engagement and tapped working memory, long-term memory and other high-level cognitive processes.
Other participants were instructed to engage in more familiar activities at home, such as listening to classical music and completing word puzzles. And, to account for the possible influence of social contact, some participants were assigned to a social group that included social interactions, field trips, and entertainment.
At the end of three months, Park and colleagues found that the adults who were productively engaged in learning new skills showed improvements in memory compared to those who engaged in social activities or non-demanding mental activities at home.
The study has been published in Psychological Science.
