Brain Training Games - Do We Need Them?

By Lia Lyn


Until quite recently, most neuroscientists believed that core aspects of cognitive processing were essentially fixed from a young age, with little or no room for improvement. Capacities like memory, attention, and sensory processing were thought to be largely determined after a relatively brief period of early development. In this worldview, those endowed with strong cognitive capacities through genetics and early development was destined to operate at a high level throughout much of their lives. Those not so fortunately endowed were out of luck.

The understanding that the brain is changing dynamically throughout life has revolutionized our way to look at cognition. We don't believe anymore that children are stuck with the brain they were born with. We don't believe anymore or that aging means inevitable loss of memory. Today we understand that our brain changes constantly and there is a multitude of ways to improve our brain's functions.

The science of the brain is changing the way we see these different issues today. We now understand that with the right stimulation, our brain can become more effective in processing information and solving problems. The brain can dramatically change and remodel itself to become more efficient in paying attention, remembering and thinking creatively.

The capacity of the human brain to make new associations and acquire new knowledge has been appreciated for hundreds of years. However, the brain's ability to fundamentally reorganize itself when confronted with new challenges is a relatively recent discovery. In response to these challenges, the brain will adapt and change. Given the right kind of exercise, it will reshape itself to be more efficient and effective. This power of reshaping is referred to as neuroplasticity, and its consequences are only now beginning to be fully appreciated.

Training can improve cognitive outcomes. Interactive multimedia software technology, like that used in video games, can be used to present specific task demands to individuals in a form that is intensive, repeatable, adaptive, and highly targeted. This advance in technology, combined with a new appreciation of the brain's ability to reshape itself, has led to an explosion in interest in using computer-based technology to train the brain.
