What research evidence is there to support the theories of the role of the father in attachment?
Geiger (1996) - father's play interactions were more exciting in comparison to mothers (mothers more affectionate & nurturing)
Hardy (1999) - fathers were less able to detect low levels of infant distress
Field (1978) - fathers can be the nurturing attachment figure as when they are the primary caregiver, they spend more time smiling, holding hands etc.
