Ein kleiner Junge, etwa 2 Jahre alt, und seine etwa 5jährige Schwester spielen vor ihrer Hütte unter Aufsicht ihrer Mutter. Es kommt dabei zu Interaktionen von Rivalität, kontrollierter Aggression und Eingreifen der Mutter. Später spielen die beiden allein, wobei auf Distanz aggressive und/oder kämpferische Handlungen mimisch dargestellt werden; besonders tut dies der Junge. (Spiegelaufnahmen)

A little two-year-old boy and his approximately five-year-old sister are playing in front of their hut under the eyes of their mother. During the children's interactions many instances of rivalry and aggressive quarrels about the object with which they are playing can be observed. The little boy acts without any restraint, whereas his elder sister controls her aggressive intentions. There are only a few instances where the mother interferes. Later, both siblings are playing alone. Now we observe their mimic expression of menacing and fighting activities directed towards an imaginery person in "empty space", so to speak.
