What Kids Forget Today They May Recall Tomorrow

While adult memories tend to fade with time, a new study has found that small children may experience the opposite effect in what is known as “delayed remembering.” In a new study, researchers found that children are able to recall previously forgotten information days later.

For the study, researchers asked four and five year-old children to play a video game in which they had to remember word-pair associations. They found that those who re-played the game after a two-day delay scored more than 20 percent higher than kids who re-played it later the same day.

“An implication is that kids can be smarter than we necessarily thought they could be,” said Kevin Darby, a doctoral student in psychology at the Ohio State University and co-author of the study. “They can make complex associations, they just need more time to do it.”

The research is the first to document two different but related cognitive phenomena simultaneously: “extreme forgetting” — when kids learn two similar things in rapid succession, and the second thing causes them to forget the first — and delayed remembering — when they can recall the previously forgotten information days later.

The findings “give us a window into understanding memory and, in particular, the issue of encoding new information into memory,” said lead study author Dr. Vladimir Sloutsky, professor of psychology at Ohio State and director of the university’s Cognitive Development Lab.

“First, we showed that if children are given pieces of similar information in close proximity, the different pieces interfere with each other, and there is almost complete elimination of memory,” Sloutsky said. “Second, we showed that introducing delays eliminates this interference.”

“It seems surprising that children can almost completely forget what they just learned, but then their memories can actually improve with time.”

The study involved 82 children, ages four and five, from central Ohio preschools. The children played a picture association game on a computer three separate times. The first time, they were shown pairs of objects, such as a baseball cap and a rabbit, and told whether the pairs belonged to Mickey Mouse or Winnie the Pooh. To win the game, they had to match each pair of objects with the correct owner.

Kids learned the associations fairly easily. At the beginning of the game, they were scoring an average of 60 percent, but by the end of the game their average scores had risen to around 90 percent.

The children then played the game again immediately after, but the researchers scrambled the pairs belonging to Mickey and Pooh, so that the kids had to learn a completely new set of associations with the exact same objects.

Similar to the first time, the kids started out scoring around 60 percent, and ended around 90 percent — scores that proved they were able to learn the new picture associations.

The researchers wanted to test whether learning the new associations in the second game caused the kids to forget what they learned in the first game, so they had half of the kids play one more time the same day. For the final game, the researchers brought back the original pair associations from the first game.

And it seemed that the kids did indeed experience extreme forgetting. They began the third game scoring around 60 percent, and ended scoring around 90 percent —  the same as if they were learning brand new information.

The other half of the kids didn’t play the third game until two days later. Darby explained why.

“We know from previous research that kids struggle to form complex associations in the moment, so we thought that with some time off and periods of sleep they might be able to do better,” he said. “And it turned out that when they had time to absorb the information, they did better.”

In fact, they ended up scoring a lot better: Kids who had taken a two-day break began the game with an average score of nearly 85 percent, and finished with a score just above 90 percent. Their final scores were similar, but they remembered enough to start out with a 25-point advantage over kids who didn’t get a two-day break.

Sloutsky said that, for children, learning the pair associations is similar to learning things like rules, schedules, or arrangements. For example, a child may have to remember that on Saturdays she can use the scooter and her brother plays video games, but on Sunday she plays video games and her brother uses the scooter.

The findings suggest that children may have difficulty remembering such things in the moment, but once they have had a few days to absorb the new information, they can remember it later.

Sloutsky cautioned that the study does not in any way suggest that kids can absorb adult-sized quantities of information if only they are given time to sleep on it. Instead, it means that they can absorb kid-sized quantities of information given time, even if they seem to forget in the moment.

“We’ve shown that it’s possible for children’s memories to improve with time, but it’s not like we uncovered a method for super-charging how much they can remember,” he said. “The takeaway message is that kids can experience extreme forgetting, and the counterintuitive way to fight it is to let time pass.”

The study is published in the journal Psychological Science.
