Within this framework, some secure infants favor independent exploration, some prefer interactive play. Some cry during separation, others do not. And reunion behavior ranges from active distance interaction to close contact. These patterns tend to be stable across time and are entirely consistent with the organization and adaptive function of the secure base concept. T he most surprising aspect of infant attachment behavior is that ineffective secure base behavior in the Strange Situation finds two very different expressions.
Avoidant infants show little greeting or proximity seeking in reunion episodes.
They may in fact abort active approaches, actively avert gaze, or ignore the mother's call. They may also show flashes of anger in their expression or cries.
