Final answer:
Valencia, as an American teenager, is most likely to feel greatest peer pressure to conform to personal choices like fashion and music, as adolescents typically experience significant peer influence and desire acceptance within their groups.
Step-by-step explanation:
Valencia, being an American teenager, will likely feel the greatest pressure from peers to conform to personal choices, such as choice of clothing and music. During the psychosocial changes of adolescence, teenagers tend to become more independent from their parents and more closely tied to their peer groups. As they spend more time with peers, the influence and acceptance within these groups grow in importance. The desire to conform can often be seen in areas such as fashion and entertainment, where teens may place great value on fitting in and being accepted.
Adolescents are also working on developing their own system of moral and ethical values, and with the increasing emotional separation from parents, the impact of peer influence becomes significant. Conformity to peer standards can play a large part in their lives, as they often follow social norms to avoid feeling out of place or subjected to criticism.
