Game Mechanics Matter: Differences in Video Game Conditions Influence Memory Performance.

We collected behavioral evidence to support the hypothesis that video game conditions have varying influences on hippocampus-dependent memory. Results indicate that participants who played in the video game conditions with clear reward mechanisms performed better on a declarative memory task than those who played in the video game conditions without reward mechanisms. Those who reported spending more time gaming weekly also performed the task better than those who reported spending less time gaming weekly, suggesting that gaming might have short-term and long-term effects on the hippocampus.
