A little practice goes a long way, according to researchers at McMaster University, who have found the effects of practice on the brain have remarkable staying power.

The study, published this month in the journal Psychological Science, found that when participants were shown visual patterns—faces, which are highly familiar objects, and abstract patterns, which are much less frequently encountered—they were able to retain very specific information about those patterns one to two years later.

"We found that this type of learning, called perceptual learning, was very precise and long-lasting," says Zahra Hussain, lead author of the study who is a former McMaster graduate student in the Department of Psychology, Neuroscience & Behaviour and now a Research Fellow at the University of Nottingham. "These long-lasting effects arose out of relatively brief experience with the patterns – about two hours, followed by nothing for several months, or years."
