Baseball may be America's favorite pastime recreational reading is more consistently ranked highly.
It’s not hard to see why recreational reading is simultaneously engaging and relaxing, and it’s fun to do alone and with friends. A team of researchers at the Beckman Institute for Advanced Science and Technology has uncovered yet another reason to love reading. It may help preserveÂ memory skillsÂ as people and their brains grow older. Their work is reported inÂ Frontiers in Psychology.
“Leisure reading, the kind that sucks you in, is good for you, and it helps build the mental abilities on which reading depends,” said Beckman researcher Liz Stine-Morrow, the study’s senior investigator.
One of theseÂ mental abilitiesÂ is episodicÂ memory, or memory for events, which allows us to remember what happened in previous chapters of a book and to make sense of the ongoing story. Another ability is working memory, the capacity to hold things in our minds as we engage in other mental processes. Working memory helps us keep track of things that happened in recent paragraphs as we continue reading.
Both episodic memory and working memory tend to decline as we get older, but habitual readers routinely practice these skills in different contexts.
There’s a pretty robust literature showing that there’s a relationship between working memory and both language comprehension and long-term memory. Working memory seems to decline with age, but there’s a lot of variation, especially amongÂ older adults.
Study into the connection:
A mystery surrounding the relationship between reading and memory is whether it’s reading that helps to improve memory or if strong working memory abilities improve reading comprehension skills. Knowing the direction of causality will have important implications on the types of treatments that can help preserve memory throughout one’s life.
Stine-Morrow and the interdisciplinary team conducted a study to test the relationshipÂ between reading and memory. To start, they needed a collection of interesting and engaging books the kind that sucks you in, and decided to reach out to the experts at the Champaign Public Library’s Adult Literacy Services. The list contained both familiar titles and books that the participants might not have discovered on their own. The list also contained a variety of genres from non-fiction to mystery to more complicated literary fiction.
The research team distributed these books to older adult participants in theÂ local communityÂ via iPads loaned out for the duration of the study. The iPads were also preloaded with a custom app that allowed participants to track their reading progress and answer additional questionnaires. Participants read for 90 minutes a day, five days a week, for eight weeks. A separate active control group completed word puzzles on their iPads instead of reading while tracking their progress with the same custom app.
Recreational reading does imrpove memory among the elderly:
At the start of the study, participants came to The Adult Learning Lab at the Beckman Institute, where they were assessed for different cognitive skills. It included working and episodic memory, as well as other verbal and reading skills. They were tested on these skills again at the end of the eight weeks.
The results were indisputable. In comparison to the puzzle group, the group that read books for eight weeks showed significant improvements in working memory andÂ episodic memory. Thus, the study demonstrated that regular, engaged reading strengthened older adults’ memory skills.
Future of the study:
The causal linkage between reading and memory opens several new avenues for future treatments for conditions such as Alzheimer‘s disease.
Future work could explore the longer-term benefits of reading or the possibility of tailoring a reading treatment to an individual’s taste in books.
For now, however, the message is clear. How can we stay mentally sharp as we age? Read a book.
