What did Dr. West find?
Dr. West found that action video games tend to make people think in a way known as “response learning”. In this kind of learning, players use their old habits within their game to navigate through the virtual environment. Compared to real-life, this is very different from what we know as “spatial learning”. People in real life get around by noticing clues in their environment and using landmarks. Dr. West discovered that response learning might be unhealthy for the brain.
From this most recent study, Dr. West and his colleagues concluded that action video games cause the hippocampus to shrink in size. In contrast, they saw that platform games increased the size of gray matter within the hippocampus.
