In the third situation, the attachment behavior was put into three groups based on how the child reacted to the mothers return.
Early attachment behaviour is crucial to understanding later psychiatric problems.
However the innate capacity for attachment behavior cannot be lost.
Anxiety, fear, illness, and fatigue will cause a child to increase attachment behaviours.
According to Bowlby, almost from the first many children have more than one figure toward whom they direct attachment behaviour.
These figures are not treated alike; there is a strong bias for a child to direct attachment behaviour mainly toward one particular person.
As attachment behaviours change with age, they do so in ways shaped by relationships.
The focus is the organisation (pattern) rather than quantity of attachment behaviours.
The internal working models on which attachment behaviour is based show a degree of continuity and stability.
For example, the attachment behaviors of parents offer children their first trust-building experience.
