Weiyi Ma, an assistant professor in the school of Human Environmental Science, is interested in how humans behave and develop. He and his colleague Diankun Gong, a researcher at the University of Electronic Science and Technology in Chengdu, China, approach this research topic in an unusual way — through studying video game players.

Ma and Gong began working together in 2013 at the Key Laboratory for Neuroinformation at the UEST, where Gong is currently a researcher in the area of cognitive neuroscience. Ma left China for Australia in 2014, and he started his role as an assistant professor at the U of A in 2017, but the two maintained their research collaboration.

"Gaming is a big part of our modern way of life," explained Ma. "Worldwide, 2.2 billion people spend 3 billion hours per week. In our research, we use video gaming as a medium to study human behavior in a digitized world."

In order to study how the human brain responds to video games, Ma, Gong and their colleagues at the Key Laboratory use behavioral measurements and technology such as electroencephalogram, or EEG tests, and magnetic resonance imaging, or MRI. They compare the effects of gaming on the brains of expert gamers to the effects on amateurs who have less prior exposure to video games. Using these techniques, Ma and Gong have shown that video games affect the brain in many different ways, including effects on white and gray matter, neural plasticity and visual selective attention.

Currently, the two researchers are studying what happens when habitual gamers reduce their time playing video games. They are also investigating whether oxytocin, a hormone known to increase empathy and generosity, can help people collaborate more effectively in a digital environment.

Ma explained that this field of research has applications for many different fields. For example, research has found that sports games have similar effects on sensory development as physical participation in sports. Video games could also be useful in the field of rehabilitation and communication disorders, as therapy tools to help patients increase communication and motor skills. At the University of Arkansas, Ma collaborates with researchers in psychology and music cognition.
