Final answer:
Foreclosed identities are identities that are undesirable to parents and community members, according to Erikson. They occur when adolescents adopt the beliefs and ideas of their parents or society without question, leading to a weak sense of self and confusion.
Step-by-step explanation:
Erikson refers to identities that are undesirable to parents and community members as foreclosed identities. These are identities in which adolescents do not make a conscious search for their own sense of self, but instead adopt the beliefs and ideas of their parents or society without question. This can lead to a weak sense of self and confusion about one's own identity and future.
