Relative to adults, children tended to use more regions of their brains to complete the word tasks, activating more regions near the back of the brain. At the same time, children showed less activation in some regions at the front of the brain that have been commonly seen in adult studies of word processing. In some brain regions, children and adults showed very similar levels of activation while performing the tasks. This included some parts of the frontal lobe.
