If there was an app on your phone that claimed to improve your memory, would you be willing to try it? It's hard to resist the idea of having a better memory. After all, our memories are delicate and can be affected by various factors such as diseases, injuries, mental health conditions, and aging.
In response to this perceived need, the brain training industry has grown rapidly, offering a wide range of accessible and affordable mental exercises through smartphone and tablet apps. Many researchers have found evidence suggesting that well-designed exercises can improve mental abilities and even lead to better scores on IQ tests. They compare the brain to muscles, suggesting that targeted repetition of memory exercises can strengthen and condition our memory processes, similar to how athletes engage in strength and conditioning by repeatedly exercising specific muscle groups.
In contrast to everyday activities like reading a detailed article or solving a complex puzzle, memory training apps are specifically designed to provide a more challenging workout for the brain. These apps typically involve tasks that require tracking a large number of objects while being distracted by a secondary task, such as mental calculations or exploring a game's landscape. If this brain training proves effective, it could be beneficial for individuals with brain-related disabilities or those recovering from conditions like cancer.
Critics, though, argue that while the concept is appealing, the overall evidence fails to demonstrate significant improvement in core brain processes. Additionally, despite the claims made by many apps and brain training companies, scientists have yet to identify the key factors that make an intervention truly effective or determine the best approaches to address the diverse needs of individuals seeking help.
While the question is still open to debate, there is evidence suggesting that short-term working memory training can benefit high-functioning individuals, such as college students. However, it's important to note that brain training, like diet and exercise, is unlikely to have identical effects on every individual.
