In the childlab of the Max Planck Institute for Human Cognitive and Brain Sciences in Leipzig, Germany, the linguists examine among other things, how babies and children process language. They want to know which steps are necessary to understand words and sentences.
They measure the brain activity of children by means of electroencephalography (EEG) and magnetic resonance imaging (MRI). By this, the scientists can create an image of the brain in a playful atmosphere. In some studies, they also play just with the children. For example, the researchers show three-year-olds two images with different situations and tell a little story that fits into one of the two images. The child then chooses which image matching the story.
