a mentally stimulating experience which 'gets the brain's juices flowing'．"

　　The experiment saw children given a range of cognitive tests before watching 20 minutes of a movie in either 2D or 3D and being tested again. The results showed those who saw the 3D content reacted faster and performed better in the second round of testing. Mental engagement also rose by 13% among 3D watchers. Child psychologist Dr.Woolfson added that "supportive parenting" and regularly listening to classical music can also aid a child's memory.
