From the article, Kids need more time than adults give them, study finds (Emphasis by bolding is mine):
"Children are increasingly being expected to provide an adult-level of detail and information," says David Shore, associate professor in McMaster University's Department of Psychology, Neuroscience & Behaviour. "Adults have had years to hone their perceptual skills; children - even 10 year olds - are just starting out."
The study is the first to probe so-called change blindness in children, a hot topic in psychology circles especially when it pertains to gauging the veracity of children who are called upon to give eyewitness testimony in court.
"We expect children to be adult-like, because of their proficiency on computers or because they display adult-like speech," he says, "so we give them instructions and get impatient when they can't understand what we tell them the first time. Children learn through repetition, at a pace suitable to the child, not to the curriculum. Once upon a time, kids controlled their own pace; now that pace is controlled by adults."
