Outline of episode sequence and protocol for the modified (A) and reversed (B) Strange Situation Test conditions.

The following effects across the episodes would be consistent with secure attachment towards the carer over the social control (stranger); increased passive behaviour, exploration and social play in the presence of the carer; greater seeking of proximity and attempts to maintain proximity/contact with the carer; greater vocalisation when separated from the carer; increased vigilance and orientation to the door when the carer is absent.
