title: [Aggression in peer groups during the second year of life].
abstract: 1. Very little is known about the behaviour of children in their second year and even less in their Peer-group. Aggressive behaviour among peers seems to be established at this age and it is interesting to observe it within the Peer-groups. 2. A useful definition of aggression seems to be the following one: Aggression is any physical contact, direct or indirect, by which another person is hurt. 3. We observe five different forms of aggression: 3.1 Aggression by chance, without any aim, happening out of awkwardness and motoric clumsiness. This kind of aggression becomes rarer during the second year. 3.2 Manipulating one another, as shaking arm or leg of another child, pulling his hair, tapping his body and so on, giving the impression of the aggressor exploring his partner. This kind of aggression also becomes rarer during the second year. 3.3 Robbery of objects, i.e. toys being in the hands of another; the reaction of the victim is increasing during the second year. 3.4 Aggression in order to control the group and to establish leadership in connection with the development of a group hierarchy. 3.5 Pathologic Aggression, observed on a child of the group with brain dysfunction. The child overthrows others from behind, climbs on them and bites them in the ear, the neck or the cheek. 4. We still need more observation on Peer-groups of this age to know more about the beginning and development of the here described phenomena.
