Training with cognitive exercises can improve targeted mental functions, conclude the authors of a review article published recently in the journal Alzheimer’s and Dementia. The authors (Kathryn Papp and Stephen Walsh from the University of Connecticut and Peter Snyder from Brown University) reviewed ten randomized controlled trials involving cognitive training interventions in healthy adults published since 1992. They find that specific abilities such as memory, reasoning, and speed of processing can be improved through targeted training programs. This is an important conclusion, and it is consistent with the growing evidence in support of the effectiveness of cognitive training.
The authors point out that the benefits of cognitive training tend to be specific to the trained domain. So, if you want improved memory — train on games designed to improve memory. If you want improved attention — train with attention games, and so on. The relationship to physical exercise is apparent. If you want big biceps — do curls. If you want ripped abs — do sit ups. Lumosity was designed with these principles in mind. This is why the site contains over 30 games targeting cognitive functions spanning speed of processing, memory, attention, flexibility, and problem solving — a complete gym for the brain.
It is also clear from this review that there is still much to learn. Few of the studies have follow-up testing longer than a few months, and many of them lack measures of real-world benefits such as activities of daily living. However, where longer follow-ups and real-world benefits are measured, benefits are seen to be long lasting and quite general. For example, in the ACTIVE study of cognitive training in normal healthy older adults, benefits to activities of daily living are seen 5 years after the training intervention ended.
While there is still much to learn, the weight of the evidence is showing that cognitive training can be highly effective when properly designed and executed.
