A multi-institutional team has reported that it is possible for researchers to predict the performance on a video game by simply measuring the volume of specific structures in the brain.
The new study, in the journal Cerebral Cortex, found that nearly a quarter of the variability in achievement seen among men and women trained on a new video game could be predicted by measuring the volume of three structures in their brains.
AdvertisementThe study adds to the evidence that specific parts of the striatum, a collection of distinctive tissues tucked deep inside the cerebral cortex, profoundly influence a person's ability to refine his or her motor skills, learn new procedures, develop useful strategies and adapt to a quickly changing environment.
"This is the first time that we've been able to take a real world task like a video game and show that the size of specific brain regions is predictive of performance and learning rates on this video game," said Kirk Erickson, a professor of psychology at the University of Pittsburgh and first author on the study. Ann Graybiel, an Institute Professor at the Massachusetts Institute of Technology and Investigator in the McGovern Institute for Brain Research; and Arthur Kramer, a professor of psychology at the Beckman Institute for Advanced Science and Technology at the University of Illinois, were co-principal investigators on the study. Walter Boot, of Florida State University, also contributed to the research.
