The initial attachment has special emotional significance- forming the basis of all later emotional relationships. Field filmed 4 month old babies in face to face interaction with PAF mothers / fathers, and SAF mothers / fathers. In both variations, the PAF mother and father spend more time smiling, imitating and holding hands than SAFs. Linking to reciprocity and IS, all part of attachment formation and quality (Isabella et al). Fathers then have the potential to be emotion focused PAFs, providing the required responsiveness- but perhaps only when given the role of PAF.
