roles they are taking on differ from one group to another. These differing roles and positions people fill are a result of their interactions with others and are called role identities. Role identities may be self-realized, or may be facts like being a mother, a social worker, or a blood donor. Role identities lead people to act in certain ways due to assumed expectations for the roles. Because there is satisfaction in complying with expectations of the role, there is often distress behind an inability to appear congruent to one's identity as defined by societal norms. There is also an existing hierarchy of importance for roles that individuals take on, and according to the hierarchical standing of roles, people become more representative of roles that stand higher hierarchically, according to them. Identity salience, the likelihood of role identities being invoked in different situations, is the result of role identities being placed hierarchically in different orders from person to person. People who hold the same roles may act differently because some roles are valued over others. For example, a working mother may have less time to spend with her child as opposed to a mother that does not work. Behaviors are reflective of the identities that are held higher hierarchically by people, so people act out in self-worth and self-meaning according to these hierarchies. Someone who holds the identity of being a psychologist higher than the identity of being a linguist will find that while he/she may become competitive when meeting another person that is better at psychology than he/she, he/she won't care when in contact with someone who is much better at being a linguist than he/she. In a similar way, social relationships are influenced by this salience. Self-identity often places individuals in social contexts and a commitment to the role within that context becomes a big part of perpetrating the idea of self. It also finds people relating more to others that hold similar role identities at the top of their hierarchies. Because people have self-concepts that are derived from a role they define for themselves within the context of a group, when staying within their roles, intergroup similarities are accentuated while intergroup differences are diminished. In an attempt to assimilate oneself according to the tendencies of a group, often people reconfigure their intragroup representations or identities. Certain prototypes form about these groups that reaffirm rules that members of
