Researchers from Johns Hopkins University discover brain-training method to improve working memory
The researchers at Johns Hopkins University have made a groundbreaking discovery in the field of cognitive training. They have found that a specific brain-training method can significantly improve working memory, a key component of our daily cognitive function.
Working memory is crucial for learning and adapting to new information quickly. It has been linked to literacy and numeracy skills, making it an essential aspect of our cognitive abilities. Scientists have long been searching for effective ways to enhance working memory, and now, researchers at Johns Hopkins University have found a promising solution.
In a recent study published in the Journal of Cognitive Enhancement, the researchers compared two main types of brain-training exercises: “dual n-back” and “complex span.” They recruited 136 young adults and divided them into three groups to engage in these exercises for a month.
After analyzing the participants’ brain activity using electroencephalograms (EEG), the researchers found that those who had completed the dual n-back task showed a 30 percent improvement in working memory. This improvement was almost twice as much as those who had completed the complex span task.
Furthermore, the participants who engaged in the dual n-back task also showed changes in the activity of the prefrontal cortex, a brain region crucial for attention and memory. This suggests that the dual n-back task specifically targets the brain areas responsible for real-world problem-solving tasks.
The researchers are now focused on understanding why the dual n-back task is so effective in enhancing working memory. They hope to adapt this exercise for consumer use or clinical applications in the future.
This groundbreaking study sheds light on the potential of targeted cognitive training to improve cognitive abilities. It emphasizes the importance of choosing the right brain-training methods to achieve significant results in enhancing cognitive function.
