Abstract
Using an example of a goose which grew up in complete isolation, this article shows how escape behaviour increases through all its developmental steps by lack of a sufficient secure primary attachment object. If a gosling has no mother, its fear influences wide parts of its behaviour and blocks the capacity to approach another animal in order to form a new attachment. But the urge for attachment is still alive and provokes strong conflicts between this urge and fear. In these situations displacement activities and apathy occur – attachment-disordered behaviour. Under partly artificial circumstances, a change to ‘normal’ attachment behaviour took place by reduction of escape motivation, which enabled the goose to accept her brood. From this moment on the attachment-disordered behaviour, the displacement activity and the apathy disappeared. Implications to human behaviour are drawn – a comparison between displacement activity and neurotic symptoms, the state of apathy and personal disorder. A synthesis of ethological and psychoanalytical models concerning etiological and therapeutic aspects is discussed. Fear and attachment, not aggression and sexuality – our ‘animal heritage’ – are the primary factors which influence our development. The balance of fear and attachment is the basis for a healthy or unhealthy development of social relationships. This applies to social living animals as well as to humans.
