Smartphones could improve memory - study

Smartphones and other electronic gadgets have been an ubiquitous part of many people's lives for years now. But while the myriad of apps that are available include many that can help us not forget important details or dates, there has always been some debate around how good these gadgets are for our own internal memories. Now, new research has shed a light on the subject.

According to the study, published on August 1 in the Journal of Experimental Psychology: General, external memory devices can actually improve memory for information that someone has never saved.

For the study, led by University College London (UCL) researchers, 158 volunteers were asked to play one of three memory task games involving high and low value circles on a touchscreen digital tablet or computer. The researchers found that digital devices help people to store and remember very important information. This, in turn, frees up their own memory to recall additional, less important pieces of information.

Participants who tended to use the digital devices to store the details of the high-value circles in the trial, demonstrated a memory improvement of 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.

Senior author, Dr Sam Gilbert (UCL Institute of Cognitive Neuroscience) said: “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.”
