By this point (about 7 months old), most infants formed an attachment to their primary attachment figure (PAF), and so begin to show separation anxiety from them. The PAF forms from the quality of the relationship, not the quantity of time spent, i.e. the sensitivity and responsiveness of the figure increases the quality of the relationship. The relationship with this figure is then believed to become the template for future relationships (internal working model). Here, infants also show stranger anxiety. In 65% of children, the PAF is the mother, compared with 3% being the father. Interestingly, 39% of infants were not primarily attached to the person feeding/ physically caring for them.
