Changes in the way people perceive attachment tend to occur with changes in the way people perceive support. One study looked at college students' perceptions of attachment to their mothers, fathers, same-sex friends, and opposite-sex friends and found that when students reported changes in attachment for a particular relationship, they usually reported changes in support for that relationship as well. Changes in attachment for one relationship did not affect the perception of support in other relationships. The link between changes in attachment and changes in support was relationship-specific.
