Using Smartphones Can Help Improve Your Memory Skills

Experts have suggested that overuse of digital devices could cause the determination of cognition. However, recent research suggests differently.

The use of digital devices might actually benefit you instead of causing you to become lazy.

According to a recent study conducted by University College London (UCL) researchers, utilizing digital devices like smartphones may actually benefit individuals’ memory skills rather than making them lazy or forgetful.

The study, which was published in the Journal of Experimental Psychology: General, demonstrated that using a digital device may aid in the storage and recall of very important information. Their memory is thus freed up to remember other, less important things. 

Neuroscientists have previously raised worry that excessive use of technology might lead to cognitive decline and “digital dementia”. 

The new study, however, demonstrates that utilizing a digital device as external memory helps individuals recall knowledge not only saved into the device, but it also helps them to remember unsaved information too.

Researchers created a memory game that can be played on a touchscreen tablet or computer to show this. 158 people, ranging in age from 18 to 71, participated in the experiment.

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 to remember half of the trials and they were allowed to set reminders on the digital device for the other half.

The results found that participants tended to use digital devices to store the details of the high-value circles. And, when they did so, their memory for those circles was improved by 18%. Their memory for low-value circles was also improved by 27%, even in people who had never set any reminders for low-value circles.

However, results also showed 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.

Senior author, Dr. Sam Gilbert (UCL Institute of Cognitive Neuroscience) 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. But 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. But 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.”

  • I really enjoyed the your article using digital devices improved memory. I also believe it helps other features of cognitive recognition. I notice my 78 year old mother using her cell phone to enjoy Tic Toc and other news cycles about crime in the news that she enjoyed 📚 reading. I thought at first this was not a good practice for her to do. Yet my mother has been ill and alone for a while. As I notice her using the device I realized that the device became her helpful companion and was a way to keep her happy and alert to people and things in the world. I find her when I awake up at 4am or 6am in the morning using this helpful tool for her . It gives her joy and somehow reduces her stress or illnesses and helps her not be alone. She does worry about losing her eyesight. But remarks to me that she is happy that her sight has not completely failed her and the diminish capacity of her sight is mostly her fear of going blind. That terrorizes her and me. But your article who's name I cannot recall now is true. Digital devices with apps like Google and TicToc and even Facebook helps with memory and other cognitive activities of the brain especially memory. The point of adding higher and lower value points as a reward to help memory is good as is the key point to save what one needs to higher recall to print or to the digital device one uses to insure that higher value information has a protection to be retained.I really enjoyed reading your article. My momma would Thank you too but she does not know that I read your posting yet I Thank you for providing this helpful information as it helps me to care for my mother.
