The major classes of roles, i.e. target children (blue), mothers (green), investigators (red) and fathers (black), are shown. Length normalization by prefix with is used. Swedish lacks the class ‘investigator’. In order to facilitate the visual inspection of the series, the few points with MLU above 15 are not shown (this concerns English and German).
