How smartphones can help boost people’s memory skills

Smartphones can boost people’s memory skills, according to a new study.

Scientists say that rather than making us lazy or forgetful the digital devices are actually good for us.

The researchers say smartphones store very important information, which frees up our brains to remember other things.

The University College London team say using a phone as an external memory not only helps people remember what’s stored in the phone, it helps them remember unsaved information too.

Neuroscientists have previously been worried that using too much technology could reduce our brain function and even lead to a form of “digital dementia.”

For the study, the team developed a memory task to be played on a touchscreen digital tablet or computer.

The test was taken by 158 people aged 18 to 71.

Participants were shown up to 12 numbered circles on the screen, and had to remember to drag some of these to the left and some to the right.

The number of circles that they remembered to drag to the correct side determined their pay at the end of the experiment.

One side was designated ‘high value,' meaning that remembering to drag a circle to this side was worth 10 times as much money as remembering to drag a circle to the other ‘low value’ side.

Participants performed this task 16 times.

They had to use their own memory on half of the trials and they were allowed to set reminders on the gadget for the other half.

Results showed participants tended to use the digital devices to store the details of the high-value circles.

When they did so, their memory for those circles was improved by 18 percent.

Their memory for low-value circles was also improved by 27 percent, even in people who had never set any reminders for low-value circles.

The results also unearthed a potential cost of using reminders.

When they were taken away, the participants remembered the low-value circles better than the high-value ones, showing that they had entrusted the high-value circles to their devices and then forgotten about them.

The study’s senior author Dr. Sam Gilbert said: “We wanted to explore how storing information in a digital device could influence memory abilities.

“We found that when people were allowed to use an external memory, the device helped them to remember the information they had saved into it.

“This was hardly surprising, but we also found that the device improved people’s memory for unsaved information as well.

“This was because using the device shifted the way that people used their memory to store high-importance versus low-importance information.

“When people had to remember by themselves, they used their memory capacity to remember the most important information.

“When they could use the device, they saved high-importance information into the device and used their own memory for less important information instead.

“The results show that external memory tools work.

“Far from causing ‘digital dementia,' using an external memory device can even improve our memory for information that we never saved.

“We need to be careful that we back up the most important information.

“Otherwise, if a memory tool fails, we could be left with nothing but lower-importance information in our own memory.”

The findings were published in the Journal of Experimental Psychology.
