Articulography enables precise analysis of speech movements that are not visible from the outside. Small sensors are glued to the speech organs (tongue, jaw, lips), which can be made visible by a magnetic field. Speaking is a motor activity that takes place so quickly that we hardly become aware of how we coordinate individual articulators. The aim of the research is to gain basic insights into the complex interaction of the speech organs.

In language acquisition research, the narrative abilities of children are examined with picture stories. The design of the pictures makes it possible to capture different areas in a targeted manner. The three protagonists in the picture, the bird, the fox and the fish, all have a masculine genus. Thus, in German terms like 'er' and 'der' are ambiguous and are avoided by adults, for example, in order to allow the listener a clear assignment with terms like 'the fox'.

Structure trees are a simple way to display the structure of sentences and parts of sentences. The different levels can be used to illustrate the individual constituents and their relationship to each other. In the sentence 'Peter already knows that she will come soon', for example, there is a closer relationship between 'Peter' and 'knows' than between 'she' and 'knows'. A structure tree always represents only one possible analysis of the constituents.

In linguistic usage there is often a clear difference between literal meaning and actual use: "The wheat beer" in the picture literally refers to a drink. But the term "wheat beer" can also be used to refer to the drinker. The separation between literal meaning and use is generally found in the linguistic theory of meaning and is an important first step in exploring the human ability to communicate meanings with language.
