Playing 3-D video games (platformers?) can boost memory formation, UCI study finds
For their research, Craig Stark and Dane Clemenson of UCIs Center for the Neurobiology of Learning & Memory recruited non-gamer college students to play either a video game with a passive, two-dimensional environment (Angry Birds) or one with an intricate, 3-D setting (Super Mario 3D World) for 30 minutes per day over two weeks.
Before and after the two-week period, the students took memory tests that engaged the brains hippocampus, the region associated with complex learning and memory. They were given a series of pictures of everyday objects to study. Then they were shown images of the same objects, new ones and others that differed slightly from the original items and asked to categorize them. Recognition of the slightly altered images requires the hippocampus, Stark said, and his earlier research had demonstrated that the ability to do this clearly declines with age. This is a large part of why its so difficult to learn new names or remember where you put your keys as you get older.
Students playing the 3-D video game improved their scores on the memory test, while the 2-D gamers did not. The boost was not small either. Memory performance increased by about 12 percent, the same amount it normally decreases between the ages of 45 and 70.
