Sara Festini wants you to remember your password.

And, if after being prompted to change it, you later try to log in with an outdated password, and 颅鈥� for the life of you! 鈥� you cannot remember the new one, Festini, associate professor of psychology, wants to know why.

That鈥檚 the gist of Festini鈥檚 current research question into prioritization within working memory 鈥斅爋r it鈥檚 at least a relatable way to remember what it鈥檚 about.

Working memory is the front-of-mind, day-to-day information people use to make decisions, from updating a password to remembering a new person鈥檚 name. Festini鈥檚 research is sponsored by a three-year, $277,536 grant from the U.S. National Science Foundation to investigate interference and incentivization in working memory, to understand how people can remember better what is most important to them in the here-and-now.

For example, imagine being introduced to six people at your company鈥檚 holiday party, and one of them is the darling daughter of the CEO, but the others you might never see again. How will you remember the daughter鈥檚 name when you bump into her at the punchbowl later? Will you accidentally call her by one of the others鈥� names? Or did you think to yourself,聽Just smile and nod 鈥� no need to remember these people聽鈥� and deliberately forget the others鈥� names from the get-go?

鈥淚 wanted to find out with this NSF grant how people naturally prioritize information,鈥� Festini said. 鈥淚f we tell them that certain information is more or less important, what types of differences or what types of factors influence if somebody is going to actually remove the information from working memory?鈥�

In the lab, Festini and undergraduate student researchers test and study participants鈥� working memory using words with point values attached. People tend to be faster and more accurate at recalling words with higher point values. Conversely, if a word is assigned a negative point value, it is more likely 鈥渢hrown out鈥� of peoples鈥� minds, and therefore it is less likely to clutter working memory 鈥斅爉aking the other high-value words easier to remember.

Interestingly, Festini has found that low- or no-value words tend to be retained, too, suggesting that 鈥減eople aren鈥檛 as aware that to have optimal performance, it鈥檚 actually beneficial to remove the low value or less important information,鈥� Festini said.

Like an obsolete password or the names of five interlopers at the company party.

Festini鈥檚 project also includes NSF funds for a community partnership with Glazer Children鈥檚 Museum, across the river from campus. Psychology students are employed through the grant as museum assistants, interacting with children and their caregivers to teach concepts like memory and executive function through an exhibit based on the colored-button, beeping, batteries-not-included Simon memory game. (Reach into your long-term memory for this one.)

The object is to remember the order the colored lights appear as they are projected on a wall. Players tap the wall to repeat back the patterns. Each successful repetition results in a longer, more challenging next sequence that builds upon the last. Red. Red-Green. Red-Green-Blue. Red-Green-Blue-Green. And so on.

鈥淭o play this game, you have to remember the order of the lights in your working memory, and you鈥檙e using executive functioning to strategically plan and sequence the order of your behaviors,鈥� Festini explained. 鈥淭hose are similar executive skills that we鈥檙e using when we鈥檙e prioritizing information in working memory.鈥�

The exhibit exposes children to psychological science at an early age. What鈥檚 a good score? It depends.

Maggie Hayes 鈥�26, a psychology major and museum assistant, explained that older children, like 7- or 8-year-olds, and adults tend to do better, which makes sense, given psychological development.

鈥淟ittle kids don鈥檛 have well-developed executive functioning,鈥� she said. 鈥淭hey can鈥檛 grasp the concept of having to wait or having to do it in order. So even if you kind of tell them, 鈥榃ait, wait,鈥� they don鈥檛. Even if you explain that they need to do it in order, they鈥檒l just press whichever one flashed most recently.鈥�

Psychology major Juan Diego Cela Rivera 鈥�27, also a museum assistant,聽notices the same, with some older children鈥檚 sequences reaching double-digits. Occasionally, a preschooler will surprise him, though.

鈥淪ometimes, you might see a 3-year-old, and they do better than a 7-year-old,鈥� he said. 鈥淭hat鈥檚 impressive. I tell them, 鈥榊ou're almost gonna break my record.鈥� And, I mean, I鈥檓 20 years old!鈥�

His record? 17.

Seventeen?

鈥淚t鈥檚 the highest score I鈥檝e seen,鈥�
he said.

His secret, he says, is 鈥渟uper focus鈥� and tapping fast 鈥斅燼nd not letting his fellow museum assistant distract him with talking or telling jokes, strategies Festini calls 鈥渉eightened attention鈥� and 鈥渋nhibition of distractors,鈥� types of executive functioning skills.

In the future, applied research from the current project could investigate how to develop better study strategies for students or initiate interventions for individuals who have difficulty with focusing, like people with attention deficit hyperactivity disorder. Those with post-traumatic stress disorder might benefit, as well, Festini said, by learning ways to remove information from their minds.

But right now, determining the basic science and understanding of how working memory works is the priority. That, and community education.

鈥淭he broader impacts of the NSF grant are to share our knowledge and expertise about this field and have (families) get excited about the mind,鈥� Festini said.

Hayes said she鈥檚 seeing this firsthand.

鈥淚 like when the parents play the game themselves. I like when the parents ask about the concepts, and I get to talk about psychology with them. They ask about what we鈥檙e doing, and they鈥檙e interested in the University. It鈥檚 part of the community.鈥�
