USC College psychology graduate student John Prindle investigates memory training’s impact on everyday functioning in older adults.
These days older adults are turning to a variety of methods to keep their brains active and maintain their cognitive abilities: Crossword puzzles. Sudoku. Nintendo has even created “Brain Age,” a video game billed to give the mind “the work out it needs.”
USC College’s John Prindle wondered whether in addition to improving memory, such exercises also bolster one’s ability to perform everyday activities such as balancing a checkbook or following a recipe.
Prindle’s psychology master’s thesis examines the randomized clinical trial data provided by a large-scale federal study, Advanced Cognitive Training for Independent and Vital Elderly (ACTIVE). Funded by the National Institutes of Health (NIH), the study involved collecting data from adults ages 65 to 94, from six locations nationwide. The roughly 2,800 participants made up three experimental groups targeting three areas of cognition — memory, reasoning and speed of processing. There was one control group. ACTIVE researchers hoped to prove that such cognitive training translates into everyday gains.
But Prindle, a third-year doctoral student, found that was not the case. Relying on quantitative methods in psychology, he determined that while the training helped subjects’ memory abilities as compared to the control, there was no difference between how the two groups performed in everyday tasks.
“So in that way the treatment failed to do what the designers of the study hypothesized,” Prindle said. “The goal of the study was to show that focused memory training would improve everyday abilities and the results from my work show there was no transfer.”
“It remains to be seen whether these computer games and everything just help you be better at the task you are performing or if it helps you out overall.”
Can any training improve memory in everyday tasks? Prindle suggests other forms of memory training, or some other cognitive ability (reasoning or speed of processing), should be explored if one wants to improve everyday abilities through a cognitive intervention.
John McArdle, professor of psychology and gerontology in the College and Prindle’s adviser, emphasized the significance of Prindle’s findings.
“Since so many elderly are impacted by memory failures, and will do most anything to prevent these declines, John’s results lead to practical suggestions for improvements in this important applied area,” McArdle said.
Prindle and McArdle also co-wrote a paper published in the December issue of Psychology and Aging that examines reasoning, one of the three experimental groups from the ACTIVE dataset.
“John is a great student colleague,” McArdle said. “My research team would not be doing such good work at this advanced level without his extensive knowledge and hard work.”
Prindle presented his findings as part of a poster event for third-year doctoral students sponsored by the Department of Psychology on Dec. 10. Students either presented aspects of their master’s thesis projects or other projects they presented at professional meetings. Participants included:
